Abstract

The invention relates to a high-water-content municipal solid waste landfill percolate on-site different-position treatment device. Garbage heaps on a landfill are surrounded by a pollution control unit to be isolated from underground water, rain water and air; a percolate collecting unit is located at the lowest sides of the garbage heaps to collect percolate of the garbage heaps; a percolate storage unit is used for storing the percolate of the percolate collecting unit through a pump; a percolate treatment unit is connected with the percolate storage unit through a pipeline to perform advanced treatment to the percolate; a ventilation unit can suck waste gas of the garbage heaps or blow fresh air to the garbage heaps; and a gas recovery or torch combustion treatment unit can purify thewaste gas pumped by the ventilation unit and recovery or combustion treatment are carried out. According to the high-water-content municipal solid waste landfill percolate on-site different-position treatment device, water level of the landfill can be quickly reduced, the generation of garbage percolate can be reduced, degradation of organic materials can be accelerated, and the pollution can be reduced; and rapid close of the landfill can be achieved, the treatment cost is low, and the high-water-content municipal solid waste landfill percolate on-site different-position treatment device is suitable for a garbage landfill accumulated by pit-pond garbage.

Description

technical field [0001] The invention relates to a garbage landfill treatment device, in particular to an in-situ heterogeneous treatment device for leachate of a domestic garbage landfill with high water content. Background technique [0002] Some of the existing informal landfills come from the accumulation of garbage in the original pits and ponds. The height of the garbage accumulation is equal to or lower than the surrounding ground. There are no anti-seepage measures and gas drainage measures for the bottom of the site and the garbage dump , rainwater can directly infiltrate into the garbage dump body. Low-lying areas can collect surrounding rainwater, or some areas of pits and ponds are water bodies, and the water body and leachate are integrated to form a large amount of sewage, which may pollute surface water and groundwater; at the same time, methane and hydrogen sulfide are produced during the decay of organic matter in garbage and other irritating gases, pollutin...
