摘　　要：送选取某已封场生活垃圾堆场,1a内多次对其排放污染物(地下水、渗滤液和填埋气体)取样并检测,结果表明,地下水13项水质检测指标超标7项(总大肠菌群、高锰酸盐指数、总硬度、氨氮、挥发酚、氯化物、pH),占比53.8%;渗沥液11项监测指标超标7项(化学需氧量、总氮、悬浮物、氨氮、粪大肠菌群、铬、五日生化需氧量),占比63.6%;填埋气体(管道和环境空气)的甲烷浓度均达标。提出了规范城市生活垃圾填埋场建设和管理的若干建议。An already closed municipal solid waste landill site was chosen to carry out several times of sampling and examination for one year on emission pollutants in groundwater,leachate and landill gas.It has indicated that seven groundwater variables out of thirteen ones,namely total coliform group,permanganate index,total hardness,ammonia-nitrogen,volatile phenols,chlorides and pH values,were incompliant with the relevant standard accounting for 53.8%;and seven leachate variables out of eleven ones,namely COD,total nitrogen,SS,ammonia-nitrogen,fecal coliform,chromium and five-day BOD,were in excess of the specified standard limits accounting for 63.6%.Meanwhile,methane concentration in landfill gas(both in pipeline and in ambient air)was all in compliance.Some suggestions have been given for standardizing the construction and management of municipal solid waste landill sites.
