摘要
我国生活垃圾卫生填埋场数量较大,尤其是早期的简易填埋场,对场地周边居民和环境产生了一定的影响,随着国民经济及环保技术的发展,亟待对简易垃圾场进行整治与封场。以四川省某生活垃圾卫生填埋场为例,在场地环境与地质背景基础上,通过对填埋场垃圾堆体封场覆盖、填埋气体导排、渗沥液导排、防洪与雨水导排、挡墙及场地绿化等主体工程的封场设计及实施,控制了垃圾渗滤液和垃圾填埋气体的污染,避免场地及周边地表水和地下水受到污染,保证了周边居民健康及环境安全。
There are a large number of domesticwaste sanitary landfills in China,especially the early simpledomestic waste landfills,which have a certain impact on the surrounding residents and the environment.With the development of national economy and environmental protection technology,it is urgent to renovate and close the simple domestic waste landfills.In this paper,a domestic waste sanitary landfill sitein Sichuan Province is taken as an example to study the closure design.On the basis of the environmental geological background of the site,through the research on the closure design of the main works such as landfill cover,landfill gas drainage,leachate drainage,flood control and rainwater drainage,retaining wall and site greening,the pollution of landfill leachate and landfill gas is controlled to avoid the pollution of surface water and groundwater around the site,and protect the health and environmental safety of surrounding residents.
