How to deal with the garbage in the dump? What are the methods and processes for garbage disposal?

In the process of real estate development and operation, garbage disposal in garbage dump is a problem that cannot be ignored. Reasonable disposal of garbage is not only related to environmental sanitation, but also affects the value of surrounding real estate and the quality of life of residents. The following will introduce the methods and processes of garbage disposal in detail.

Garbage disposal methods mainly include the following. Landfill is a common treatment method, which fills the garbage into the prepared pit and then compacts the covering soil layer. This method is relatively simple in operation and low in cost. But it also has some disadvantages, such as occupying a lot of land resources, and harmful substances in garbage may penetrate into soil and groundwater, causing environmental pollution.

Incineration method is to burn garbage at high temperature and convert it into ash, gas and heat. Incineration can significantly reduce the volume of garbage, and at the same time, it can also use the generated heat to generate electricity or heat. However, some harmful gases, such as dioxins, will be produced in the incineration process, which will cause serious pollution to the atmospheric environment if not handled properly.

Composting method is to use microorganisms to decompose organic matter in garbage and turn it into organic fertilizer. This method is suitable for treating garbage containing a lot of organic matter, such as kitchen waste. Composting can not only reduce the amount of garbage, but also produce fertilizer beneficial to the soil, but the composting process takes a long time and requires high classification of garbage.

The process of garbage disposal generally includes four links: collection, transportation, treatment and disposal. In the collection process, it is necessary to classify and collect garbage according to its types and properties, which is helpful for the subsequent treatment. For example, separate recyclables, harmful waste and other garbage.

In the transportation link, special garbage transport vehicles need to be used to ensure that garbage will not leak and emit odor during transportation. Transport vehicles should be cleaned and maintained regularly to ensure the safety and hygiene of transportation.

The processing link carries out corresponding operations according to different garbage disposal methods. If the landfill method is adopted, the garbage needs to be compacted and covered; When incineration is adopted, the incineration equipment should be strictly operated and managed; When composting is adopted, the conditions such as temperature, humidity and ventilation of composting should be controlled.

The disposal link is to arrange the treated products reasonably. For the garbage after landfill treatment, long-term monitoring and maintenance should be carried out to prevent environmental pollution problems; For the ashes produced by incineration, it is necessary to carry out safe landfill or comprehensive utilization; Organic fertilizer produced by composting can be used in agricultural production and other fields.

In order to compare the advantages and disadvantages of different garbage disposal methods more clearly, the following is a simple table:

processing method advantage disadvantage? burial method,burying method Simple operation and low cost. Occupy land, pollute soil and groundwater Incineration The volume reduction effect is good, and energy can be recycled. Harmful gas is generated, and the equipment investment is large. Composting method Can produce organic fertilizer Long processing time and high classification requirements.

In the actual garbage disposal work, appropriate disposal methods and processes should be selected according to the characteristics of garbage, local environmental conditions and economic conditions, so as to realize effective garbage disposal and rational utilization of resources and create a good environment for real estate projects.

Donation, transformation, cross-border … See where the abandoned bike-sharing has gone.

  A Burmese bought ofo and oBike bicycles that were abandoned overseas and donated them to poor children. On June 20th, a batch of modified bike-sharing was sent to a rural school near Yangon. Local students no longer need to walk far to school every day. This is undoubtedly a blessing for those abandoned bike-sharing.

  Two years ago, bike-sharing was the darling of capital, and the number of bike-sharing in the city was increasing day by day, and eventually it was surplus; A year ago, when the wind blew away, some entrepreneurs who were swimming naked faded, and there were fewer and fewer players in bike-sharing, leaving only abandoned bicycles and bicycle cemeteries. It is estimated that by 2020, at least 10 million bike-sharing vehicles will be scrapped, which will not only occupy public space and land resources, but also produce at least 160,000 tons of municipal waste. So, where have all those deserted bike-sharing gone?

  donate

  Non-profit organizations buy bicycles

  Donate it to Burmese students after transformation.

  According to foreign media reports, Mike, a foreign entrepreneur, founded a non-profit organization called LessWalk, bought 10,000 bicycles from enterprises in bike-sharing, and plans to donate them to students in Myanmar.

  In rural Myanmar, it is very common for students to walk a long way to get to school. Some students walk from home to school for more than an hour every day. Many families can’t afford bicycles or motorcycles, and school buses are unheard of for these children.

  LessWalk made a simple transformation on the bought bike-sharing, added a back seat to them, converted the QR code scanning lock into a common key lock, and then transported them to Myanmar. Most of these bicycles were purchased from liquidators, who controlled oBike’s closed business in Singapore and inherited ofo’s abandoned fleet, which made their purchase price cheaper than ordinary bicycles.

  At the end of April, the first batch of 3,300 bicycles arrived in Myanmar, and on June 5, another 1,000 ofo bicycles were delivered to the warehouse in Yangon. Mike said that they bought a total of 4000 bicycles from ofo.

  He said that the average price of bicycles is about S $20 (about RMB 100). Together with transportation, modification and distribution costs, the cost of each bicycle is about 35 US dollars (about RMB 240 yuan). He bought 5000 cars out of his own pocket, and the other half was sponsored by sponsors. Mike hopes to call on friends from all over the world to join his plan to "regenerate" hundreds of thousands of abandoned bicycles.

  Ofo’s branch in the United States announced in mid-2018 that it would shrink its related business in the United States. A spokesman for ofo in the United States declared: "They will not be thrown into the garbage dump. We hope to leave these little yellow cars here and give them to people who need them." Ofo said that more than 40,000 small yellow cars it put into use will not be abandoned on the streets, nor will they become urban garbage and occupy public resources. At present, it has donated about 3,000 bicycles to local communities and charitable organizations in 10 evacuated cities. In the future, ofo will donate more cars in more cities.

  After ofo withdrew from India, bicycles were recycled by Bounce, a shared scooter company. After ofo announced the closure of business in Israel and other Middle Eastern countries, it also donated bicycles to local charities.

  Sorting bicycles that have reached the scrapping cycle.

  Ofo promotes recycling

  In China, ofo claims that bike-sharing has a complete recycling process to ensure that obsolete vehicles can be effectively disposed of.

  Not long ago, some media reported that thousands of ofo sharing bicycles cars were crushed into scrap iron in a demolition factory in Xuefu Section 2, Wuhou District, Chengdu, and then recycled and transported away by the scrap factory at the price of 15 yuan per car. The relevant personnel of the scrap factory said that there were about 3,000 small yellow cars at the scene.

  The small yellow car with an ex-factory price of several hundred yuan was eventually sold as scrap iron, and many people expressed "distressed". In this regard, the relevant person in charge of ofo responded that the scrapping clean-up is under the supervision of the government, and the normal management behavior of enterprises on vehicles involves only a very small part of the amount of vehicles put into Chengdu, which has reached the retirement age.

  Last year, ofo said that it had reached a strategic cooperation with Beijing Vanke, China Circular Economy Association and Beijing Urban Renewable Resources Service Center to promote the recycling of used bicycles, so as to recycle the bike-sharing that has reached the end-of-life cycle and realize the green closed-loop management of the whole life cycle from production, use to recycling.

  Mobike made furniture and runways.

  Realize 100% recycling.

  On Earth Day on April 22nd this year, mobike and YUUE Product Design Studio in Berlin jointly released a group of creative cross-border cooperation to turn bicycle parts into furniture products, such as recliners, vertical lights, coffee tables, desktop finishing racks, candlesticks, etc. All the raw materials of these furniture are from discarded parts in mobike, which shows the new achievements of mobike’s "life cycle" plan.

  For example, the mobike classic front fork was transformed into a desktop finishing rack: the front fork has its own internal criss-crossing reinforcing ribs, which naturally divides the container into several parts. The connection between the added PC material and the front fork makes full use of the original screw holes, just like the mortise and tenon structure, and a desktop finishing rack with fashionable appearance and practical function was born.

  "mobike will be scrapped one day after serving for thousands of kilometers. Although every mobike’s materials can be recycled through recycling, we hope that they can be revived through simple transformation, which is also a more environmentally friendly and energy-saving measure. " Qin Hao, a senior expert on sustainable development in mobike, said. In July 2018, mobike took the lead in putting forward and actively practicing the concept of life cycle environmental protection in the industry. In the whole process of design, procurement, production, delivery, operation and scrapping, the "3R principle" (Reduce, Reuse and Recycle) was implemented, and the used bicycles were 100% recycled, realizing energy conservation and environmental protection in the whole life cycle of mobike.

  Not long ago, a plastic multifunctional playground made of waste tires from mobike was laid on the playground of Wanhua School in Yan ‘an. According to reports, the particles donated to the plastic site come from the waste tires recycled in mobike, all of which are solid polyurethane tires made of polyurethane materials specially developed by Dow Company. This is another use of recycling in bike-sharing.

  According to the introduction of mobike, the maintenance records of each vehicle’s components are recorded on the intelligent life cycle management platform in mobike, which can clearly trace the service life of each component, and optimize the design and production of vehicles according to the maintenance records, so as to improve the service life of vehicles and reduce the resource consumption and carbon emissions caused by maintenance. Among them, smart locks, solar panels and wheelsets will be recycled and reused after passing the test. As of a year ago, mobike had recycled more than 300,000 tires in cooperation with manufacturers.

  In addition, mobike cooperated with China Renewable Resources Development Co., Ltd. and Tianjin Xinneng Renewable Resources Co., Ltd. to provide mobike with professional services such as recycling, dismantling and harmless treatment after the end of bicycle life cycle.

  Hello, waste wheels become cat nests.

  Recycling according to material differences

  Not long ago, at the scene of a public welfare activity, the stray cat nest made by parents and children with bike-sharing’s used wheels was very eye-catching. The bottom of the nest formed by overlapping tires ensures a certain distance from the ground, which can not only prevent the nest from being soaked in rainy days, but also increase its own weight and make the nest not easy to topple; The nest is made of three wheels, leaving room for stray cats to move, and waterproof cloth is wrapped to effectively block strong winds and rain.

  In fact, since last year, Harrow Bicycle has transformed some bicycle waste wheels into stray cat nests, and placed them in the places where stray cats often appear on campus, giving them a warm home in winter.

  Hellobike said that it will sort and recycle bicycle parts according to their material differences. Metal materials such as the main frame are recycled to make metal ingots for recycling, and the plastic of the car body is granulated for secondary processing, and the parts that cannot be completely decomposed, such as tires and cushions, are treated scientifically and harmlessly.

Internet access in China for 20 years: the structure of netizens is optimized and the access equipment is diverse.

 In 2014, China achieved the 20th anniversary of full-function access to the Internet. In the past twenty years, the construction level of Internet infrastructure such as backbone network and broadband network in China, and the number of Internet basic resources such as IP number, domain name number and website number have all entered the international advanced ranks; In addition, the number of Internet users in China surpassed that of the United States in June 2008, ranking first in the world.

The number of netizens has increased steadily, but the imbalance between urban and rural areas is still significant.

According to the 35th Statistical Report on Internet Development in China published by CNNIC, as of December 2014, the number of netizens in China reached 649 million, and the Internet penetration rate was 47.9%. From 1997 to 2000, with Yinghaiwei Company opening its Internet service to ordinary families, and then Sohu.com and People.com went online, the Internet development in China entered an active period, and the number of netizens doubled, with the growth rates of 238.7%, 323.8% and 152.8% in the three years from 1998 to 2000 respectively. In the first decade of the new century, with the gradual recovery of the Internet in China from the bursting of the bubble and entering the web2.0 era, the continuous innovation of Internet applications has driven the total number of netizens to continue to grow at a high speed; Since 2009, the growth rate of netizens has continued to slow down and entered a platform period.

 

picture one  1997-2004yearThe scale of netizens in China

 

Judging from the absolute scale of Internet users, China is undoubtedly the largest Internet country, but judging from the structure of Internet users, there is still a problem of unbalanced regional development in China’s Internet popularization. Although the number of netizens in rural areas has also maintained a rapid growth rate, its Internet penetration rate is still far lower than that in urban areas. As of December 2014, the Internet penetration rate in rural areas was 28.8%, an increase of only 0.7 percentage points compared with 2013. The gap between urban and rural Internet access in China makes the vast rural residents "on the unfortunate side of this gap, which means that they have few opportunities to participate in our new information-based economy and online education, training, shopping, entertainment and communication" (US Department of Commerce). Internet should be one of the powerful tools to break the urban-rural dual system. Solving the digital access gap between urban and rural areas will help to fundamentally solve the problem of unbalanced regional development in China.

 Mobile devices have penetrated into the lives of netizens, and network TV has become a new hot spot.

The whole industry in cmnet has maintained a strong development trend. From 2006 to 2009, the penetration rate of mobile Internet increased rapidly, and the number of mobile Internet users doubled. After 2009, the scale of mobile Internet users has increased steadily. In the context of the slowdown in the overall growth rate of Internet users, mobile Internet access has become the main driving force for the overall scale of Internet users in China. By 2012, mobile phones have become the largest internet terminal for Chinese netizens; In 2014, the proportion of Internet users using mobile phones reached 85.8%, and the proportion using tablet computers reached 34.8%. In 2014, China’s telecom industry officially entered the 4G era. The 4G network will greatly promote the development of the mobile Internet in the future with faster communication speed, lower tariffs and carrying capacity for large data transmission.

 

picture three  1999-2014The scale of rural netizens and rural Internet penetration rate in China

 

In 2014, Internet companies launched fierce competition around the "living room", and TV is becoming an important Internet access device. According to CNNIC data, as of December 2014, the proportion of netizens using TV to access the Internet has reached 15.6%. In the same period, according to the data released by the Ministry of Industry and Information Technology, the number of IPTV users in China has reached 33.636 million. As a mixed form of traditional TV and OTT TV, network TV will be further integrated with terminals, making TV a comprehensive digital home terminal with communication, Internet and TV functions. If the mobile phone is the mobile revolution of the traditional Internet, then network TV will become the living room revolution of the network society.

Guo Fucheng: Stop calling me Guo Tianwang, Andy Lau is old, I’m not old (Photo)






Guo Fucheng profile photo


  "Standing in the rain, with tears in my eyes, I don’t know where to go," Guo Fucheng was always at the bottom of the ranking of the Four Heavenly Kings. In the eyes of the outside world, in addition to having sexy abdominal muscles, he seemed to be the weakest and most controversial among the Heavenly Kings. Time flew, and after the peak of the "Four Heavenly Kings", Guo Fucheng, who has won two consecutive Golden Horse Best Actor, is more concerned about movies.


  state


  Andy Lau is old, I am not old


  When talking to Guo Fucheng, he sat in front of the glass window of the hotel room, wearing a white shirt. Although he happily chatted with reporters about the past and present lives of the Four Heavenly Kings, he no longer wanted anyone to call him "Guo Tianwang" or "idol". "Idols no longer exist for me. Some people say that Jacky Cheung and Andy Lau are old, but I am not old, and I must work hard to win those so-called awards. As an actor, I can accept wrinkles, but if a singer comes out with wrinkles, I can’t stand it myself."


  award


  Let me let go of my idol burden


  In 2005, Guo Fucheng, who had been silent for almost three years, won the Taiwan Golden Horse Award for Best Actor with his mature image in the movie "Sanchakou".


  Looking back on the experience of winning the first Best Actor Award, he said with a smile: "I feel a little surprised, a little surprised, because for my opponents at the same time, I am more optimistic about Liang Jiahui. Winning this award has a great impetus for my future performances. You know, when you let go of the burden of idols, you realize that there is still so much room for development in the film."

  If there are crocodiles in the river, they have to jump


  "Detective C +" is Guo Fucheng’s first film since he won the title of the best actor in a row. He plays a private investigator who takes the audience step by step to uncover the culprit behind the cold case. In this movie, Guo Fucheng needs to jump into a stinky ditch and get into a garbage heap, which must be very difficult for a person like him who is very careful about his image. To this, he said with a smile: "The garbage is fake, and I thought at the time that it must be very stinky. In fact, the scene I couldn’t stand was jumping into a river, because the color of the river was darker than my hair, and there was oil floating on it. I asked the director’Do you really want to jump? ‘He put on a look of helplessness. The assistant director next to me said to me,’ My assistant and the actor saw a crocodile in the river. ‘"


  This year Jacky Cheung and Andy Lau have both come to the mainland for concerts. Many people expect all four kings to come, but Guo Fucheng said that now he is more focused on doing a musical well. "I will not rest in music, but in the days to come, I will invest less in music and more in movies."

Reminder | New scam! Do you know the mobile phone extension? Someone lost 50 thousand overnight

  CCTV News:Pretending to be an acquaintance to borrow money, pretending to be a public security bureau, a procuratorate or a court officer to investigate a case, and hiding a Trojan link &hellip in short messages and QR codes; … These tricks must have made everyone immune, but do you know? Some telecommunications services that you have never heard of have also begun to become new traps set by scammers!

The mobile phone was locked and more than 50,000 yuan was stolen.

  When he woke up, Mr. He in Shenzhen found that his mobile phone was locked. At the same time, a shopping platform account was stolen by strangers. Criminals used white bars to spend and apply for loans, and robbed more than 50,000 yuan overnight.

0

  Later, Mr. He discovered that his mobile phone had been taken over by a strange number. The short message from the operator shows that this is a business to add a secondary number, and Mr. He’s mobile phone number was added as a secondary number by criminals. When the secondary phone is turned off, all short messages will be received by the primary phone, and criminals will receive Mr. He’s short message verification code during this period, and then commit crimes.

"Subnumber" ≠ "kinship number"

  Without an ID card, a bank card or even a real name, the money is gone. What the hell is a minor number?

  Many people think of "family number" at first, but "deputy number" and "family number" are not the same thing.

=

  Family number usually refers to the phone bill package opened by different owners and different numbers in order to make calls between them cheaper, and the secondary number is the "one card with many numbers" service provided by operators. On the basis of not changing mobile phones and SIM cards, users can add up to three real mobile phones as secondary numbers. The main and auxiliary numbers can stand by at the same time, and you can freely choose any number to dial, answer the phone and send and receive short messages as needed.

Don’t reply to text messages too casually.

  Then, how did Mr. He’s mobile phone number become the "secondary number" of criminals?

  Reduction of criminal modus operandi

  Step 1: Buy materials.Criminals buy leaked names, bank card numbers, ID numbers and reserved mobile phone numbers online, commonly known as "four big pieces".

  Step 2: Fishing.Criminals apply to the users who have mastered the bank card information, initiate the business application of binding the sub-number, and find the target of the crime by casting a net widely. Once you reply by mistake, you are hooked.

  Step 3: Forced shutdown.Because the main number can only take over the SMS when the secondary number is turned off, criminals usually use two means at this time. One is to use SMS bombing to force the target to turn off the mobile phone, and the other is to use the mobile phone cloud service to remotely operate the mobile phone.

  Step 4: White Wolf with Empty Gloves.Using the SMS verification code received by the main number, criminals ransacked the online shopping account bound to the mobile phone number.

  Patterns are stacked, and it is impossible to prevent them! For this kind of fraud, after receiving all kinds of SMS notifications, you must read the content of the SMS clearly and do not reply at will.

"SMS custody" business is also not very secure.

  After the SMS storage service is opened, you can save your mobile phone messages on the server of the operator. Now, many mobile phone manufacturers’ cloud services are doing the same thing. However, this is a hidden danger function.

  Case review

  One morning, Miss Ding saw two short messages from banks and mobile phone operators on her mobile phone, which were sent at 3:43 am and 4:12 am respectively. As soon as the account is checked, the balance of more than 100,000 yuan will be zero overnight! Not only that, Miss Ding also suffered a credit card theft and was "applied" for a bank universal loan of 70,000 yuan.

  How on earth did all this happen?

  Reduction of criminal modus operandi

  Step 1: Hit the database to get all kinds of account information.The so-called "library collision" means using software to try a high probability digital sequence. Using this simple and rude method, the user’s network identity, online banking account number, mobile phone business hall and other accounts can be seen at a glance. Insiders said: "The speed of library collision is very fast, at least thousands per minute. If some good equipment is used, the efficiency is higher and the success rate is above 50%."

  Step 2: Open SMS storage and SMS interception services to obtain verification code.This is the most critical step. After the opening of this service, the dynamic verification code to ensure the safety of landing has successfully become the bag of criminals.

  Step 3: Open the physical SIM card.At this point, criminals can pretend to be victims and apply for 4G card replacement service in the online business hall. For the convenience of the people, some operators can express the card directly to the designated address.

  By intercepting short messages and copying SIM cards, fraudsters can "do whatever they want".

  As we all know, many important services rely on mobile phone authentication. If you back up the SMS to the server synchronously, it will increase the exposure opportunity. Once the service password of the online business hall is stolen, or the login permission of the cloud service is stolen, it is equivalent to "swimming naked".

The loopholes in the unpopular business are targeted by scammers.

  The "Research Report on the Trend of Online Fraud in 2016" released by the anti-fraud reporting platform "Hunting Network Platform" proposes that since 2016, online fraud has mainly shown several obvious characteristics:

  Mobile phone cards have become new theft targets;

  Jump to the phishing website by using short URL and weiyun sharing link;

  Well-known recruitment websites and voice platforms for open recruitment;

  A phishing website that is difficult to distinguish between true and false;

  The implementation of precision fraud;

  Fraud professionalism is getting higher and higher;

  Using loopholes in new business and unpopular business to commit fraud;

  Use cloud disk and synchronization software to steal information.

  Among them, the loopholes in mobile phone cards and unpopular business are mentioned.

  Security experts suggest that we should develop good online habits, don’t click unfamiliar links, don’t fill in our personal information in the website interface with unknown security, and regularly modify the password of social accounts to avoid information such as mobile phone contact information being leaked; Improve safety awareness, develop good habits of using mobile phones, and avoid being infected by mobile phone viruses.
