论龙岩市生活垃圾焚烧厂配套填埋场防渗工程施工管理

Discussion on construction management of anti-seepage system engineering of Longyan municipal solid waste incineration plant

龙岩市生活垃圾焚烧厂为有效处理垃圾焚烧所产生的炉渣,以及经固化、稳定化处理后的飞灰,建设了配套填埋场。为杜绝填埋场渗沥液的外渗,同时防止地下水向填埋库区的渗入,并确保填埋场安全可靠的运行,减少渗沥液产生量,避免造成二次污染等问题,建设科学安全有效的防渗系统工程对于填埋场工程来说至关重要。通过对填埋场内部防渗系统的简要介绍及阐述,对适合此配套填埋场的防渗材料、衬层系统和衬层结构以及防渗材料铺设等问题进行了深刻的分析。

In order to effectively dispose the slag generated from waste-incineration and the flying ash after stabilization, an assorted landfill has been built in municipal solid waste incineration plant of Longyan City. To reduce the leachate production and avoid its corresponding secondary pollutions, a scientific and effective seepage system engineering for the landfill site is very important. Such engineering is able to preclude the extravasation of landfill leachate, prevent the infiltration of groundwater to landfill area, and ensure a safe and reliable operation for landfill site running. This study briefly introduced the inside anti-seepage system of the assorted landfill. In addition, the choice of anti-seepage material, lining system, and lining structure which are suitable for the assorted landfill are investigated in detail.
