黄家湾垃圾填埋场终场覆盖方案及雨污分流系统设计

摘要

The scientific design of landfill cover and rain sewage diversion system is a powerful guarantee of landfill sites to prevent potential hazards .By summing up the lessons learned in engineering practice ,and combined with some of the problems found in the Huangjiawan landfill operations ,this article analyzes the structure and composition of the cover system , ad puts forward cover system solutions for Huangjiawan landfill site in accordance with appropriate national regulation .Meanwhile ,combined with the current rain and sewage diversion measures in the landfill site ,and the existing experience of the rain and sewage diversion ,the article also designs the rain and sewage diversion after the landfill closure by the forecast the closure terrain .%指出了垃圾填埋场终场覆盖和雨污分流系统的科学设计是防止其潜在危害的有力保证。以宜昌市黄家湾垃圾填埋场为例，结合实际运营中情况及特点，分析了其终场覆盖系统的结构及组成，依照相应国家规范提出了黄家湾终场覆盖系统方案，同时通过预测封场后的地形，结合填埋场现有的雨污分流措施及已有的雨污分流经验，设计了填埋场封场后的雨污分流系统。
