A high-efficiency anti-seepage method for landfills for domestic waste treatment

Abstract

The invention discloses a high-efficiency landfill anti-seepage method for domestic waste treatment, which belongs to the technical field of anti-seepage treatment, and can be used as the basis for anti-seepage by layering and anti-seepage, and innovatively introduces settlement two-state water reduction Layer, using the characteristics of microorganisms to treat landfill leachate, the landfill leachate of domestic waste and the heat generated in the microbial treatment process are double-sedimented and drained to the settled two-state water-reducing layer, firstly through split-flow adsorption filtration combined with microbial treatment, Decompose the polluting components in the landfill leachate, and then heat the landfill leachate by storing and absorbing heat to make it evaporate, and discharge it out of the landfill along the pre-buried pipeline to collect and recycle water resources and heat energy. The way of active drainage and prompting double-state change is used to efficiently treat landfill leachate, thereby significantly improving the anti-seepage effect of the landfill.

Description

technical field [0001] The invention relates to the technical field of anti-seepage treatment, and more specifically relates to an efficient landfill anti-seepage method for domestic waste treatment. Background technique [0002] Leakage from landfills pollutes the environment and is very harmful. After the soil is polluted, it will be salinized and poisoned. Parasites, pathogenic bacteria and other pathogens in the soil can make people sick, and seepage can also pollute groundwater, and eventually Enter the human food chain and cause serious harm to the human body. Since the 1980s, HDPE high-density polyethylene geomembranes with a thickness of 1-2 mm have been used in anti-seepage treatment of landfills in foreign countries, which has become a mature technology and has been more and more applied. my country's environmentally friendly landfills started relatively late, but in recent years, under the attention of the State Environmental Protection Administration and the imp...

AI Technical Summary

Problems solved by technology

[0004] The existing landfill anti-seepage system is relatively simple, and the anti-seepage effect is poor. Generally, the anti-seepage effect on external water is better, but the waste permeate with a high degree of pollution is difficult to treat, and it is difficult to rely on the way of microbial treatment in the waste. After treatment, the anti-seepage effect will inevitably decline over time, resulting in different degrees of leakage
