四川红层地区简易垃圾填埋场地下水污染现状调查及防治对策
|
摘要
基于红层地区6座简易填埋场进行地下水水质监测,统计识别了红层地区简易垃圾填埋场地下水的主要污染物种类;通过标准指数法、评分法、污染指数Pki法对XX县简易生活垃圾填埋场地下水质量及污染现状进行评价。结果表明:6座简易填埋场区域地下水水质较背景井水质下降严重,为较差~极差(FI=7.10~7.36);红层地区简易垃圾填埋场地下水中高锰酸盐指数、氨氮、亚硝酸盐和铁、锰污染程度最严重;针对研究区填埋场情况,建议就地封场,下游敏感的填埋场可采取垂直防渗措施。
Based on the groundwater quality monitor in 6 simple landfill sites located in red beds,pollutant species of the groundwater in these areas were investigated by statistical identification. And ground water quality and pollution status of a simple landfill in a county was evaluated through standard index method,scoring method and pollution index( Pki) method. Results showed that the groundwater qualities of 6 simple landfills decreased a lot,which is poor-badly( FI = 7. 10 ~ 7. 36). And groundwater of simple landfills in red beds was the most serious polluted. Permanganate index,ammonia nitrogen,nitrite,iron and manganese were the most severe pollutants. It is suggested that the landfill of the study area should be closed and the vertical anti-seepage measures should be taken for the sensitive landfill downstream.
