Problems solved by technology
Due to the complex composition of waste, great differences in physical, chemical and biological characteristics, and the limitations of landfill structure design, it is impossible to provide a suitable growth environment for microorganisms, and the degradation process of waste is limited. Therefore, traditional sanitary landfills The waste degradation process is slow, the stabilization period is long, the degradation is incomplete, the gas production rate is low, and the leachate composition is complex

Embodiment Construction
[0023] In order to illustrate the technical solution of the present invention more clearly, the present invention will be briefly introduced below using examples. Obviously, what is described below is only an embodiment of the present invention. For those of ordinary skill in the art, On the premise of paying creative efforts, other technical solutions can also be obtained according to these embodiments, which also belong to the disclosure scope of the present invention.
[0024] The urban waste environmental protection treatment system of the embodiment of the present invention is arranged in a landfill, see figure 1 , including anti-seepage protection layer 10, filtrate discharge layer 20, alternately arranged landfill layers 30 and intermediate covering layers 40 from bottom to top. The anti-seepage protection layer 10 is arranged at the bottom of the landfill, and is used to prevent landfill leachate from migrating to the groundwater and polluting the groundwater body. In...

An environment-friendly disposal system for municipal waste comprises an anti-seepage protection layer, a percolate drainage layer, waste landfilling layers, middle covering layers, a percolate collection system and a percolate recharging system, wherein the anti-seepage protection layer is used for preventing waste percolate from moving to underground water and polluting the underground water; the percolate drainage layer is used for draining percolate generated in a landfill site; the waste landfilling layers are used for conducting landfilling of municipal waste needing to be disposed; each middle covering layer is used for covering the corresponding waste landfilling layer; the percolate collection system is used for generating the percolate; and the percolate recharging system is used for recharging the percolate. The percolate recharging system comprises a plurality of sets of recharging pile columns. Each set of recharging pile column comprises a first recharging pile column assembly and a second recharging pile column assembly which are arranged in a crossed mode. Each recharging pile column comprises a three-way pipeline, wherein the first pipeline communicates with the percolate collection system, the second pipeline is a vertically upward open pipeline, an included angle of about 30 degrees is formed between the third pipeline and the vertical plane, and a permeation hole is formed in the middle of the third pipeline.
Description
technical field [0001] The invention relates to a solid waste treatment system, in particular to an urban garbage environmental protection treatment system. Background technique [0002] With the expansion of city size, the increase of urban population and the improvement of residents' living standards, the output of urban waste is increasing day by day. [0003] It increases the difficulty of garbage disposal, brings difficulties to urban development and management, and seriously threatens the survival and health of urban residents. [0004] Due to the complex composition of urban waste, affected by the level of economic development, energy structure, natural conditions and traditional habits, the composition of urban waste varies greatly. Therefore, the treatment methods for urban waste vary with different national conditions, and often different cities in a country also adopt different methods. However, in the end, the harmless, resourceful and reduction of waste is the ...
