Improved structure of irregular refuse landfill
The invention provides a modification structure of an irregular refuse landfill, the irregular refuse landfill comprises a foundation pit used for storing refuse, the modification structure comprises: an anti-seepage wall, the anti-seepage wall is arranged around the foundation pit to define a closed area with the occupied area larger than the foundation pit so as to prevent landfill leachate from permeating and diffusing to the outside of the area; the permeable wall is arranged in the area and located at the boundary position of the foundation pit, the two sides of the permeable wall intersect with the anti-seepage wall, and a percolate collecting area provided with an extraction well is formed between the permeable wall and the anti-seepage wall; the permeable wall has the characteristic of allowing the landfill leachate to permeate and pass through, and at least part of pollutants in the permeated landfill leachate can be removed. The transformation structure of the irregular refuse landfill is simple in structure construction, low in operation cost, capable of treating the landfill leachate in situ and high in practicability.
本申请提供了非正规垃圾填埋场的改造结构，所述非正规填埋场包括用于存放垃圾的基坑，所述改造结构包括：防渗墙，其环绕所述基坑设置，围成一封闭的占地大于所述基坑的区域，以防止垃圾渗滤液向所述区域外部渗透扩散；可渗透墙，其设于所述区域内，并位于所述基坑的边界位置，所述可渗透墙两侧与所述防渗墙交汇，与防渗墙之间形成一设置有抽提井的渗滤液收集区；所述可渗透墙具有允许所述垃圾渗滤液渗透经过的特点，可除去透过的所述垃圾渗滤液中的至少部分污染物。本申请的非正规垃圾填埋场的改造结构，结构建设简单，运行成本低，能够原位处理垃圾渗滤液，实用性强。
