Final cover layer structure for early recycle of waste landfill

摘要

The present invention relates to a waste landfill structure, and more specifically, methane gas, odorous substances and volatile organic compounds (VOCs) generated from waste landfills when stabilizing waste landfills are constructed as ecological parks, sports facilities, and golf courses. The present invention relates to a final cover layer structure for early recycling of landfills to reduce or remove harmful gases, and to prevent surface dryness and partial settlement, thereby enabling early utilization of landfills.;The present invention is a waste landfill structure composed of a plurality of waste layers and the final cover layer, the entire surface is installed on top of the final cover layer, the air supply means for supplying air and gas extraction for discharging the landfill gas or reaction gas A microorganism active reaction layer of porous material provided with means; Completely formed on top of the microbial active reaction layer is achieved by the final cover layer structure for the early recycling of the landfill, characterized in that it comprises a surface layer that can be planted grass or shrub.;As such, the present invention not only forms a surface layer for planting grass or trees on the existing final cover layer, but also oxidizes landfill gas generated during the waste decomposition process using aerobic microorganisms, and at the same time blocks the transfer of waste heat from the decomposition to the surface layer. By installing a microbial active reaction layer made of a porous material that can mitigate physical shocks due to settlement, etc., it is possible to recycle waste landfill at an early stage.
