Garbage is an adjunct to urban development. The operation of cities and people generates hundreds of millions of tons of garbage every year. One side is the growing urban waste, and the other is the unbearable smell of garbage, which has become a thorny problem in urban waste disposal. The fast-growing Chinese cities are suffering from the “garbage siegeâ€.
For a long time, China has used landfill and composting methods for waste disposal. At present, China is about 80-90% of the urban life to be filled, so that not only the scarce land is invaded, but also the resources are not used. At the same time, simple landfill without technical treatment will inevitably pollute groundwater and surface water. Exposed garbage will produce a lot of harmful gases and flies, mosquitoes, mice and so on. Even the currently improved sanitary landfill, although it can prevent the waste permeate from polluting groundwater, surface water and the atmosphere, still requires a large amount of land. Composting waste is not only difficult to reduce the total amount of waste, but also low in fertilizer efficiency.
Statistics show that 2/3 of the more than 600 large and medium-sized cities across the country are surrounded by garbage, and one-fourth of the cities have no suitable place to stack garbage. The total amount of urban garbage dumped in the country is as high as 7 billion tons over the years, and the amount of production is increasing at an annual rate of about 8.98%. At present, Beijing produces 18,300 tons of garbage every day, an annual increase of 8%. The garbage disposal capacity in Beijing is currently only 10.41 million tons per day, with a gap of up to 8,000 tons.
Regarding the problem of garbage siege, Zhou Shengxian, Minister of the Ministry of Environmental Protection, also said during the "two sessions" that this is a common problem facing environmental protection. First, it is necessary to clarify responsibilities and strengthen waste management. In addition, learning from advanced foreign technology, the most important thing is to rely on technology. solve.
In this context, the Beijing International Fair on China's International Environmental Technology and Services Promotion Conference exclusively introduces and promotes the German garbage compound processing technology, in order to find a new way for Chinese cities.
It is understood that the German waste compound treatment project is the most advanced garbage treatment technology in the world. The project has the characteristics of no secondary pollution, high energy conversion rate, 100% reduction, low cost, mature technology and large-scale application. . It is treated by anaerobic fermentation treatment and "liquefaction-gasification" and converted into combustible gas, followed by power generation. The technical room of this project is far superior to the new waste-to-energy processing technology system and system solution for waste incineration power generation. It can achieve pollution-free, high efficiency and high efficiency. The whole process is completed in a closed tank. At the same time, the garbage is 100% harmless, which will not cause odor or groundwater pollution, and will not produce heavy metals and dioxins. Emission of toxic gases such as Britain.
At the same time, the German project party will also find cooperation targets through the “China International Environmental Technology and Service Promotion Conference†platform of the Beijing International Trade Fair, sign a project cooperation plan, and carry 3 to 700 million funds to promote the project. Really let technology change the city and make garbage a green resource for sustainable urban development.
According to the organizing committee of the conference, the important part of the 2013 Beijing International Trade Fair “Environmental Service†will be held--China International Environmental Technology and Service Conference (**http://jjh.cusdn.org.cn/) Supported by the China Urban Development Research Association, supported by the Chinese Academy of Social Sciences, the China International Friendship Cities Association, the Italian New Technology, Energy and Sustainable Development Agency, will be held from May 28 to June 1, 2013. The Beijing National Convention Center was held. The activities included project signing, promotion meetings, fairs, exhibitions, and visits by Chinese and foreign delegations.
At that time, the conference will invite overseas city delegations, the world's top 500 environmental giants, representatives of 483 member cities, and representatives of domestic and international environmental service industry buyers to gather the world's highest international environmental event. The conference re-launched the project to promote cooperation, will hold 4-5 international professional promotion meetings, 60 private appointments for business negotiations, 30-500 million US dollars on-site contract cooperation quotas and 4 Chinese and foreign delegations to visit each other; A high-end trading platform serving the world's environment, cooperating with the global environmental development plan, signing a contract for the world's environmental transactions, reviewing the international environment in which international environmental projects are based, and conducting overseas delegations to “bring in†and Chinese city delegations as needed. The “going out†campaign will jointly promote the trade between China and global environmental services, upgrade the level of China's environmental service industry, and build a better environment for the world.
