Refuse landfill with anti-seepage function

Abstract

The invention discloses a refuse landfill with an anti-seepage function. A first clay layer is laid on the bottom face of an arranged foundation pit; a bottom face anti-seepage film set is arranged on the top of the first clay layer and connected with a side face anti-seepage film set arranged on the side wall of the foundation pit to form an anti-seepage system on the periphery of the wall of the foundation pit of the landfill; every two adjacent refuse landfill layers are arranged in a spaced manner through the clay layer; a clay layer is further laid on the topmost refuse landfill layer so that a top face anti-seepage film set can be laid; the circumferential ring of the top face anti-seepage film set and the circumferential ring of the top of the side face anti-seepage film set are overlapped and fixed, and a closed refuse landfill structure is formed; and a plurality of main blind ditches are formed in the first clay layer and communicate with a waste liquid guiding-out pipe on the side wall of the foundation pit, and therefore waste liquid flowing into the bottom face anti-seepage film set after refuse is subjected to layered landfill is guided out. According to the overall structure of the refuse landfill, waste liquid generated by refuse can be effectively prevented from being left in the landfill, corrosivity to a permeable film on the landfill after refuse in the landfill is decayed is reduced, and accordingly damage and seepage of the anti-seepage film are avoided.

Description

technical field [0001] The invention belongs to the technical field of garbage landfill, and in particular relates to a garbage landfill with anti-seepage function. Background technique [0002] With the improvement of living standards, the output of waste in my country has also increased greatly. In the past, most of the domestic waste was treated by simple landfill in my country. The waste was degraded by digging pits for landfill and long-term weathering. . However, due to the non-standard treatment of landfills in the early stage, a large amount of corrosive garbage and polluted leachate will be produced in the process of self-degradation of long-term landfilled garbage, and polluted leachate will seep into the groundwater layer, causing damage to rivers and groundwater. Pollution has seriously affected the normal life of people around the garbage dump. [0003] In order to solve the pollution of groundwater during the process of garbage decay, existing garbage landfill...
