In the 14th five year plan, domestic waste is managed in this way
2022-02-23
Dry garbage, wet garbage and hazardous garbage. Many residents in Beijing, Shanghai and other places have been very skilled in garbage classification. How to improve the classified collection and transportation system of domestic waste in the next few years? How to upgrade the management system intelligently? Recently, the national development and Reform Commission, the Ministry of ecological environment, the Ministry of housing and urban rural development and the National Health Commission issued the guiding opinions on accelerating the construction of urban environmental infrastructure (hereinafter referred to as the Guiding Opinions), which made arrangements for the construction of a scientific and perfect domestic waste classification and treatment system. The guidance specifies that by 2025, the classified collection and transportation capacity of domestic waste will reach about 700000 tons / day and the incineration capacity will reach about 800000 tons / day; The utilization rate of urban resources reaches about 60%, and the incineration capacity of urban domestic waste accounts for about 65%. Tong Lin, director of the environmental sanitation engineering technology research center of the Ministry of housing and urban rural development, said that the guiding opinions defined the construction pattern of treatment facilities focusing on incineration, promoted waste reduction and resource utilization, and pointed out the direction for the classification and treatment of domestic waste during the 14th five year plan period. According to the guiding opinions, the classified collection and transportation system of domestic waste will be improved during the 14th Five Year Plan period. All localities will reasonably arrange domestic waste classified collection stations, improve the classified transportation system, and speed up the capacity of classified collection and transportation facilities. According to the requirements, all localities will clarify the construction objectives and tasks of facilities for classified collection and transportation of domestic waste, steadily promote the construction of facilities, and effectively connect the classified delivery end and classified treatment end, so as to avoid the "separation before mixing" of waste. At the same time, during the "14th five year plan" period, China will also fully implement the domestic waste charging system, implement the waste measurement and charging of non resident users, explore the charging of resident users according to the amount, encourage all localities to innovate the charging mode of domestic waste treatment and continuously improve the collection rate. The construction of incineration treatment facilities will be accelerated. The construction of waste incineration facilities will be accelerated in areas with a daily domestic waste removal volume of more than 300 tons in urban built-up areas. In areas that do not have the conditions to build large-scale waste incineration treatment facilities, the State encourages the construction through cross regional joint construction and sharing. Tong Lin said that during the "14th five year plan" period, we should closely follow the high-quality development requirements of waste classification and treatment, further expand the technical pattern focusing on incineration and reduce the amount of primary waste landfill on the existing basis. Orderly promote the construction of kitchen waste treatment facilities. "With the implementation of waste classification, all localities need to adopt a combination of long-term layout and transitional arrangements to speed up the construction and transformation of kitchen waste treatment facilities, and comprehensively solve the problems of food waste, household kitchen waste and farmers' market waste treatment." Tong Lin said, "according to the classified collection of kitchen waste, the characteristics of kitchen waste, the size of the population, the consumption of facility end products and by-products and other factors, scientifically select appropriate technical routes and treatment methods, and strive to solve the problem of product outlet." The Guiding Opinions also proposed that, in accordance with the principles of green, low-carbon, intensive, efficient and circular development, encourage the construction of "multiple in one" comprehensive disposal bases for the treatment, disposal and resource utilization of sewage, garbage, solid waste, hazardous waste and medical waste, and promote the construction mode of vein Industrial Park; Promote the effective connection between municipal sludge disposal and waste incineration, leachate and sewage treatment, comprehensive utilization of incineration slag and solid waste, incineration fly ash and hazardous waste disposal, hazardous waste and medical waste disposal. Tong Lin explained that this is conducive to promoting the sharing of process equipment, resources and energy, the CO treatment of environmental pollution and the sharing of responsibility and risk, realizing the rational utilization of resources, the effective disposal of pollutants, the prevention and control of environmental risks, and steadily improving the development level of facilities. Domestic waste treatment should also be upgraded to intelligent green. In the next stage, the state will promote the intelligent upgrading of the whole system of domestic waste classification management, digitally innovate the infrastructure operation and supervision mode, and strengthen information collection, sharing, analysis, evaluation and early warning; Adopt advanced energy-saving, low-carbon and environmental protection technologies, equipment and processes to promote stable emission up to standard. "The guiding opinions focus on improving the quality of urban ecological environment, which is of great significance to improve the modernization level of environmental infrastructure, promote the construction of ecological civilization and green development." Tong Lin said. (outlook new era)
