High-efficiency seepage-proofing method for landfill site for domestic garbage treatment

Abstract

The invention discloses a high-efficiency seepage-proofing method for a landfill site for domestic garbage treatment and belongs to the technical field of seepage-proofing treatment. That a sedimentation dual-state water reducing layer is innovatively introduced by taking a layered seepage-proofing mode as a seepage-proofing foundation can be realized, landfill leachate generated during the landfill of domestic garbage and the heat generated in the microbial treatment process are dually settled and drained to the sedimentation dual-state water reducing layer by utilizing the characteristic ofmicrobial treatment of the landfill leachate, pollutant components in the landfill leachate are first decomposed by combining shunting adsorption filtration with the microbial treatment, secondly, theabsorbed heat is stored to heat the landfill leachate to evaporate, and the landfill leachate is discharged to the outside of the landfill site along a pre-buried pipeline to collect and recycle water resources and heat energy, and the landfill leachate is efficiently treated in a mode of actively draining and promoting the dual-state change, so that the seepage-proofing effect of the landfill site is obviously improved.

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
