垃圾填埋场堆体整形及雨污分流治理工程改进

Improvement of Landfill Body Shaping and Rain and Sewage Diversion Treatment Project

为确保场区垃圾堆体的整体稳定性,完善雨污分流排水系统,垃圾填埋场要做好堆体整形及雨污分流治理工程。某市生活垃圾卫生填埋场通过垃圾堆体整形、重新施作渗滤液导排盲沟、更换中间覆盖膜、修建堆体雨水口等多项举措,为膜上雨水提供导排通道。这样可以有效提高雨污分流效率,减少渗滤液总量,节约处理费用,从而降低填埋场运营成本及渗滤液外溢环境污染风险。

In order to ensure the overall stability of the garbage dump in the site and improve the rain and sewage diversion and drainage system,the landfill should do a good job of heap shaping and rain and sewage diversion treatment projects.A city’s domestic waste sanitary landfill provides a drainage channel for rainwater on the membrane by reshaping the garbage heap,re-installing the leachate drainage blind ditch,replacing the intermediate covering film,and constructing the rainwater outlet of the heap.In this way,the efficiency of rain and sewage diversion can be effectively improved,the total amount of leachate can be reduced,and treatment costs can be saved,thereby reducing the operating cost of the landfill and the risk of environmental pollution caused by leachate spillage.
