How to alleviate the phenomenon of city garbage besieged city

How to alleviate the phenomenon of urban garbage siege and solve the problem of garbage siege can be carried out from the following aspects:

First, raise the awareness of national garbage classification and advocate the implementation of national garbage classification. The premise of garbage harmless treatment is to effectively classify organic matter, inorganic matter and toxic and harmful substances, and then treat and recycle them in different categories. This requires the whole people to realize the significance of garbage sorting and actively join it. It also requires * * * and relevant departments to strengthen the publicity of garbage classification and increase the number of garbage classification and delivery points in appropriate locations.

Second, change the way of garbage disposal, and actively change from landfill to incineration. Waste incineration power generation has become a common way of waste resource treatment in developed countries. This way can avoid a series of hazards caused by landfill. However, this method requires a large one-time investment, and local governments need to increase financial input.

Third, establish a unified environmental sanitation system in urban and rural areas. To some extent, the urban environment in our country is at the expense of the rural environment. This is also an important reason for the transfer of urban garbage to rural areas and the formation of a garbage siege.

Fourth, start from the source and promote the reduction of urban garbage. This is a goal that needs the joint efforts of the whole society. It is necessary to intensify publicity in the whole society and raise the environmental awareness of the whole people.

Do you have any good suggestions on how to alleviate the phenomenon of city garbage siege? Please make reasonable suggestions or plan the city reasonably. In this respect, China lags far behind the developed countries. The professional knowledge and technical personnel in this field have just taken up their jobs in recent years. It can be said that there are still many ways to go in China's urbanization. It's no problem to set up a waste incineration station like Japan, but the Chinese people don't have enough awareness of waste classification, the management of the * * * department is not in place, and the protests of the surrounding people are immature. It remains to be seen that the garbage incineration station will be established. However, I still call on Chinese people to learn garbage sorting.

How did the garbage in Beijing get out of the tens of meters deep pit full of garbage, people living in the "garbage circle", burning smoke from garbage, rampant mosquitoes and flies and cows foraging in garbage ... The photographer silently told this shocking fact in the net post with picture language.

Is there a phenomenon of garbage siege in Chengdu? At present, there is a phenomenon of "garbage besieged city" in two-thirds of cities in China. Do you have any suggestions on how to deal with this phenomenon? (Hebei Civil Service Examination 2011Interview on the morning of May 28th) Xu Xiaohui, senior researcher of Tu Hua.

Wang Jiuliang, a freelance photographer, won the Gold Award of Outstanding Artist of the Year in Lianzhou International Photographers' Annual Exhibition from June 5 to February 2009 with a group of works "Trapped Garbage". This group of works shows the little-known side hidden behind the rows of Beijing: plastic bags flying all over the sky, garbage dumps full of fireworks, rivers flowing with sewage ... Beijing has become a city surrounded by garbage.

Beijing surrounded by garbage is not an isolated case. In fact, while the rapid development of China has attracted worldwide attention, the quietly growing "garbage siege" is even more shocking. On a global scale, the whole earth has been covered with garbage. There is even a "Pacific garbage block" between the coast of Hawaii and the coast of North America, which consists of millions of tons of plastic garbage alluvial by seawater. Garbage has caused great damage to our living environment.

In fact, such consequences are closely related to the way of garbage disposal. In China, landfill is the main way to treat garbage. However, this kind of landfill brings great harm, and often a large number of highly toxic and harmful substances are buried in the soil together with domestic garbage, which concentrates a variety of harmful components. These garbage will produce a lot of methane and ammonia, which not only pollutes the environment, but also is prone to explosion. At the same time, landfill also ate a lot of cultivated land, which seriously threatened groundwater and caused secondary pollution.

Another important reason for the siege of garbage is the lack of treatment and funds. This is the dilemma faced by local sanitation departments. The cost of collection, transportation and treatment per ton of garbage in Beijing is 150 yuan to 170 yuan. Even in developed areas, municipal departments often have a headache for funds.

To solve the problem of garbage siege, I think we can start from the following aspects:

First, raise the awareness of national garbage classification and advocate the implementation of national garbage classification. The premise of garbage harmless treatment is to effectively classify organic matter, inorganic matter and toxic and harmful substances, and then treat and recycle them in different categories. This requires the whole people to realize the significance of garbage sorting and actively join it. It also requires * * * and relevant departments to strengthen the publicity of garbage classification and increase the number of garbage classification and delivery points in appropriate locations.

Second, change the way of garbage disposal, and actively change from landfill to incineration. Waste incineration power generation has become a common way of waste resource treatment in developed countries. This way can avoid a series of hazards caused by landfill. However, this method requires a large one-time investment, and local governments need to increase financial input.

Third, establish a unified environmental sanitation system in urban and rural areas. To some extent, the urban environment in our country is at the expense of the rural environment. This is also an important reason for the transfer of urban garbage to rural areas and the formation of a garbage siege.

Fourth, start from the source and promote the reduction of urban garbage. This is a goal that needs the joint efforts of the whole society. It is necessary to intensify publicity in the whole society and raise the environmental awareness of the whole people.

How to solve the problem of "garbage besieged city" in China, in short, is:

1, classified recovery, reuse, adhere to the road of sustainable development.

2, research and development of clean, pollution-free or low pollution (including pollution in the manufacturing process) materials.

3, improve the quality of the population, strengthen environmental publicity, improve people's awareness of environmental protection.

Nowadays, with the improvement of living standards, people waste more and more. According to statistics, every person throws away 1 every day. 5 kg, domestic waste is increasing at a rate of 6% every year. Paper, fruit and vegetable shells, glass, waste metal and electrical appliances have all become domestic garbage, especially plastic garbage such as packaging bags, disposable lunch boxes and various food plastic bags, which has become a worldwide environmental hazard. General plastic products can only be completely decomposed after 200-400 years in nature. If buried in the soil, it will affect the growth of crops, and if eaten by livestock by mistake, it will endanger health. If they are burned, they will release a lot of toxic gases and endanger human health. There are also waste batteries, which are also very harmful. Once the button-sized battery dives into the water, it will pollute 600 cubic meters of water and endanger the survival of aquatic animals and plants.

Garbage is so harmful, what should we do with it? Some students may think that "garbage usually goes to the garbage dump, and it is ok to have uncles and aunts from other places to deal with it, which has nothing to do with me." In fact, it is our responsibility to build a clean and beautiful environment. We are small citizens of society, and we can also contribute to the scientific disposal of garbage.

First of all, we can "reduce production" of garbage. We should refuse to use unnecessary disposable fast food boxes, plastic bags and other plastic products, and try to use green packaging such as paper boxes and reusable cloth bags. We should also save paper and reduce paper waste.

How to classify urban garbage Daily life garbage can be divided into three categories:

The first category is toxic and harmful waste (such as waste batteries, etc.). );

The second category is degradable garbage such as organic garbage;

The third category is refractory garbage (such as plastic, metal, glass, etc. ).

After garbage classification, organic garbage can be used as fertilizer for flowers and trees after treatment, renewable garbage can be distributed to relevant departments for recycling, and the rest garbage can be packaged and sent to the municipal garbage management department for treatment. This is the truly effective and correct method of garbage classified collection and centralized treatment.

How to reduce urban garbage can only be handled reasonably. At present, the most serious problem is the classified collection of garbage. If it can be classified, many problems of municipal solid waste treatment will be solved.

How to deal with urban garbage? On the basis of overcoming the shortcomings of single treatment method, the comprehensive treatment technology of municipal solid waste adopts the combination of two or more methods, such as landfill, composting, incineration and classified recovery, to avoid and reduce the secondary pollution and resource waste caused by improper treatment, and at the same time achieve the purpose of full utilization of resources and harmless treatment of municipal solid waste; In addition, this treatment method can completely treat municipal solid waste, and there is basically no secondary pollution. The recycling of resources conforms to the national sustainable development strategy. In fact, the comprehensive treatment technology of municipal solid waste (MSW) aims at the coordinated development of society, economy and environment, and is an optimized system engineering of MSW treatment through various management and technical means. According to the sequence of application, various unit treatment technologies in comprehensive treatment technology mainly include four processes: pretreatment, intermediate treatment, post-treatment and final disposal. In fact, the main unit treatment technologies that constitute these four processes include landfill, composting, incineration and recycling.

It can be seen from the changes in China's municipal solid waste treatment in the past 10 years that the achievements and progress of municipal solid waste are obvious, especially the advanced garbage treatment technology has been gradually applied. For example, in many landfill sites built in recent years, in order to improve the anti-seepage level of landfill sites, high-density polyethylene films are used as anti-seepage materials; In order to improve the efficiency of landfill operation, some large landfills adopt landfill compactors; Landfills in some cities such as Hangzhou, Guangzhou and Shenzhen began to recycle landfill gas.

Garbage incineration is from scratch. 1985, Shenzhen imported two sets of garbage incinerators with a daily processing capacity of 150 tons from Mitsubishi heavy industries, becoming the first modern garbage incineration plant in China. Some cities with good economic foundation in China, such as Shanghai, Guangzhou and Beijing, have built high-standard waste incineration plants. Most of these incineration plants are modern large-scale garbage incineration plants that use foreign capital, introduce key technologies or devices and build according to high pollution control standards.

Composting is the earliest and most commonly used treatment method of municipal solid waste in China. Composting mainly adopts low-cost composting system, and most garbage composting plants adopt open static composting. During the "Seventh Five-Year Plan" and "Eighth Five-Year Plan" period, China has successively carried out the research and development of dynamic high-temperature composting with high mechanization, and achieved positive results. At present, compared with the demand of garbage disposal, the investment in garbage disposal is still obviously insufficient, and the level of garbage disposal is still very low. Generally speaking, the treatment of municipal solid waste is still in the development stage from extensive to treatment. It is mainly manifested in the common phenomenon of garbage piling, and the secondary pollution of garbage disposal sites is quite common.

With the increase of combustible substances in garbage, the available value increases. Therefore, with the increasing popularity of gasification rate in big cities in China, especially in northern cities, the organic matter content and calorific value of municipal solid waste will be further improved.

The rapid growth of packaging waste is one of the important reasons for the growth of municipal solid waste. In fact, most of the waste paper, metal, glass and plastic in the garbage are discarded packaging materials after use. With the rapid development of packaging industry, there are more and more forms of commodity packaging, and the types and quantities of packaging materials increase rapidly. Overpackaged and luxury packaged products abound, especially in big cities. Disposable goods is widely used, which increases the output of garbage. At present, China's packaging waste accounts for more than 10% of municipal solid waste, and its volume should constitute more than 30% of municipal solid waste.

The change of residents' living standard and consumption structure not only affects the output of municipal solid waste, but also affects the composition of municipal solid waste. Especially in the last decade, with the further deepening of reform and opening up, residents' income has been increasing, people's living standards have been improving, and the consumption of packaging products and recyclable materials such as waste paper, plastics, glass, metals and fabrics has been increasing.
