Impermeable layer structure for refuse landfill

Abstract

The invention relates to an impermeable layer structure for a refuse landfill, and belongs to the field of refuse landfill equipment. The impermeable layer structure for the refuse landfill is characterized in that after a pit is dug in the surface of a foundation, a landfill pit body, a separation layer and adsorption layers are separated out through concrete slabs, the landfill pit body is located in the middle position, and the separation layer is located at the bottom of the landfill pit body, the adsorption layers are located on the left side and the right side of the landfill pit body, garbage is landfilled into the landfill pit body, the adsorption layers and a filling layer are filled with adsorption materials, the adsorption materials can adsorb gas generated by garbage decomposition, meanwhile, a liquid leakage pipe and a liquid outlet pipe are arranged at the bottom of the landfill pit body, a side liquid outlet pipe is arranged at the bottom of the landfill pit body, liquid generated by the garbage decomposition can be recycled, and a good impermeable effect can be achieved.

Description

technical field [0001] The invention belongs to the field of garbage landfill treatment equipment, in particular, the invention relates to an anti-seepage layer structure for a garbage landfill. Background technique [0002] Waste disposal methods can generally be divided into several methods such as sanitary landfill, incineration, and composting. Garbage landfill is a place where garbage is piled up under the sanitary landfill method. Garbage sanitary landfill is widely used in China because of its low cost and good sanitation. Garbage landfill generally adopts the method of layered soil filling to dispose of garbage. For processing, pile up a layer of garbage and then cover it with a layer of loess, which can easily reduce the pollution of garbage; but the main problem that needs to be avoided in the landfill is the anti-seepage problem of the landfill. Garbage will decay and decompose, and once the liquid produced by the decomposition of garbage leaks, it will pollute t...

Garbage landfill is a place where garbage is piled up under the sanitary landfill method. Garbage sanitary landfill is widely used in China because of its low cost and good sanitation. Garbage landfill generally adopts the method of layered soil filling to dispose of garbage. For processing, pile up a layer of garbage and then cover it with a layer of loess, which can easily reduce the pollution of garbage; but the main problem that needs to be avoided in the landfill is the anti-seepage problem of the landfill. Garbage will decay and decompose, and once the liquid produced by the decomposition of garbage leaks, it will pollute the soil and water sources, causing serious pollution. The seepage structure should be strictly required, and at the same time, in addition to the possibility of seepage of rotten liquid, the decomposition of garbage will also emit a pungent smell, which affects the environment. Therefore, the invention provides an anti-seepage layer structure for landfills
