摘　　要：近年来,不少地区发生了垃圾填埋场渗滤液泄漏而引发地下水污染和土壤重金属超标等问题,对当地居民生活生产用水以及粮食安全造成了严重威胁。以贵州某生活垃圾卫生填埋场为研究对象,详细调查了填埋场周边水文地质条件,对填埋场上游、场内、下游地表水进行系统取样检测,采用单因子指数法、综合评价法、灰色关联分析法对水质污染指标和水质进行了评价。结果显示:填埋场下游区域地表水部分水质指标严重超标,部分样点水体污染程度为重污染;样品中污染物主要物质成分与生活垃圾卫生填埋场渗滤液污染物主要物质成分基本一致,表明该生活垃圾填埋场存在渗滤液泄漏,对下游地表水造成了污染。In recent years,problems such as groundwater pollution and soil heavy metal exceeding the standard caused by landfill leachate leakage have occurred in many areas,posing a serious threat to local residents living and production water and food security.Taking a domestic waste sanitary landfill site in Guizhou as the research object,the hydrogeological conditions around the landfill site were investigated in detail,and the surface water in the upstream,in-site and downstream of the landfill site was systematically sampled and detected.The water quality pollution index and water quality were evaluated by single factor index method,comprehensive evaluation method and grey correlation analysis method.The results showed that the water quality indexes of some surface water in the downstream area of the landfill were seriously exceeded,and the water pollution degree of some sampling points was heavy pollution.The main material composition of the pollutants in the sample is basically the same as that of the leachate pollutants in the domestic waste sanitary landfill site,indicating that there is leachate leakage in the domestic waste landfill site,which pollutes the downstream surface water.
