Embodiment 1

[0022] The utility model relates to an end-site covering system of a domestic garbage landfill, which includes, from the bottom to the top of the garbage dump, an exhaust layer, an anti-seepage layer, a drainage layer and a vegetation layer. Among them, the material of the exhaust layer is a mixture of waste incineration slag and gravel, the mixing ratio is 5:1, the particle size of the slag is 1-10mm, the particle size of the gravel is 2-40mm, and the thickness is 25cm; the anti-seepage layer The paved material is clay with a compacted thickness of 40cm; the paved material of the drainage layer is a mixture of waste incineration slag and gravel, the mixing ratio is 4:1, the particle size of the slag is between 10 and 40mm, and the particle size of the gravel is between 40-60mm, with a thickness of 35cm; the material for the vegetation layer is a mixture of landfill soil, waste composting products and biochar, with a mixing ratio of 100:5:1 and a thickness of 20cm. Among them,...

Abstract

A domestic garbage landfill final cover system includes an exhaust layer, an impervious layer, a water drainage layer and a vegetation layer, and garbage incinerator slag is used as a main composition part of the exhaust layer and the water drainage layer to substitute natural aggregate or an artificial material; and MSW (municipal solid waste) compost products and biological carbon are added to the vegetation layer in order to greatly enhance the methane oxidation ability and improve the ecological functions of soil. The landfill final cover system comprehensively utilizes domestic garbage organisms and heat treatment (byproducts) products, and has the advantages of simple and practical technical method, strong universality, wide source and low price of raw materials, high degree of treatment of wastes by using wastes, provision of a new way to resolve the heavy metal problem restricting the recycling of perishable components in the MSW and realize the comprehensive treatment of the MSW, and remarkable economic, environmental and social benefits.

Description

technical field [0001] The utility model relates to an end-site covering system of a domestic waste landfill, which belongs to the field of solid waste management and pollution control. Background technique [0002] As of 2012, the volume of municipal solid waste (MSW) in my country has reached an astonishing 171 million tons, and it is increasing year by year at a growth rate of nearly 10%. Affected by multiculturalism such as catering, the important feature of MSW composition in my country is the super high content of perishable components (accounting for 50-70% of the total). Due to social, economic and technical conditions such as public awareness of environmental protection, regional classified collection facilities, and relevant laws and regulations, most of the perishable waste is not collected separately, but is mixed with other components into MSW logistics, making the original high-efficiency waste Treatment and recycling technologies have been tested to varying d...
