Leachate hoisting well applied to refuse landfill

Abstract

The invention relates to a leachate hoisting well applied to a refuse landfill. The leachate hoisting well comprises a leachate collection well, a well platform, a sleeve, a submersible sewage pump and a valve well, wherein the leachate collection well is formed by well drilling of a hollow twist drill, the sleeve is arranged in the leachate collection well, the wall of the sleeve is provided withmultiple sewage leakage holes, the submersible sewage pump is arranged in the sleeve, the well platform is arranged on a well mouth of the leachate collection well, the valve well is located at one side of the well platform, the valve well is internally provided with a leachate collection pipeline, the sleeve is internally provided with a leachate hoisting pipeline, an outlet of the submersible sewage pump is communicated with an inlet end of the leachate collection pipeline through the leachate hoisting pipeline, and an outlet end of the leachate collection pipeline is used for being communicated with leachate treatment equipment. The leachate hoisting well applied to the refuse landfill has the advantages that the problems of blockage of the submersible sewage pump and backflow of a leachate can be effectively avoided, the leachate hoisting well is completely arranged underground, and the aesthetics and traffic function of refuse landfill can be effectively improved.

Description

technical field [0001] The invention relates to the field of waste landfill management and repair facilities, in particular to a leachate lifting well applied to a waste landfill. Background technique [0002] With the increase of urban population and the rapid expansion of urbanization, the number and scale of urban domestic waste landfills are gradually expanding. Both new landfills and old landfills have the problem of enrichment of leachate in garbage dumps, especially for In old landfills, there is no leachate collection system, which causes the leachate water level in the pile to rise, which seriously pollutes the surrounding surface water, soil, groundwater and other ecological environments, resulting in a waste of land resources. [0003] At present, we have more and more experience in the treatment and restoration of waste landfills and similar polluted sites. The restoration and treatment of waste landfills has been gradually implemented, but there are still many t...
