Landfill leachate treatment device and treatment method thereof

Abstract

The invention discloses a landfill leachate treatment device and a treatment method thereof, and belongs to the field of landfill leachate. According to the scheme, when leachate in garbage is treated, garbage raw materials can be compressed through compression equipment, so that the leachate in the garbage raw materials seeps out, easily degradable components in the garbage and oxygen are subjected to an aerobic biodegradation reaction to generate a large amount of heat, so that ammonium chloride powder is heated and decomposed into ammonia gas and hydrogen chloride, a built-in airbag ball expands to extrude an inner extrusion ball, nitrogen and hydrogen sulfide are subjected to extrusion force to push a rubber sealing sheet open and flow out of a first flow channel, the PH value of leachate is reduced, when the built-in air bag swells until the spherical bag is punctured by a spine, a culture solution and methanogens are released, and the methanogens convert organic acid and H2 into methane, so that the organic matter concentration, the metal ion concentration and the conductivity of the leachate in the garbage raw materials are all rapidly reduced.

Description

technical field [0001] The invention relates to the field of landfill leachate, more specifically, to a landfill leachate treatment device and a treatment method thereof. Background technique [0002] Landfill leachate refers to the moisture contained in the garbage itself in the landfill, the rain and snow water and other moisture entering the landfill, deducting the saturated water holding capacity of the garbage and the covering soil, and passing through the garbage layer and the covering soil. A kind of high-concentration organic wastewater, as well as the water leaked from the accumulated garbage ready for incineration, the treatment of leachate in urban landfills has always been a very difficult problem in the design, operation and management of landfills, seepage Filtrate is the product of gravity flow of liquid in the landfill, mainly from precipitation and the water contained in the garbage itself. There are many factors that may affect the properties of leachate du...

AI Technical Summary

Problems solved by technology

[0003] At present, in the treatment process of landfill leachate, the leachate of urban waste landfill is a kind of high-concentration organic wastewater with complex components. If it is directly discharged into the environment without treatment, it will cause serious environmental pollution. Purpose, it is essential to treat the leachate. In the prior art, it may appear that the concentration of organic matter, metal ion concentration, conductivity and biodegradability in the leachate are difficult to decrease rapidly when the leachate is treated. As a result, the working efficiency of the leachate treatment is relatively low, and when the treated leachate fails to meet the sewage discharge standard, it will also be stored and cannot be discharged, which greatly reduces the work efficiency
