摘要
对贵阳市某垃圾填埋场周边土壤中主要成分进行分析,采用单因子污染指数、综合污染指数和内梅罗指数法进行评价。结果表明该垃圾填埋场沿地下水流向上土壤存在一定的污染,土壤中的污染因子主要为COD Mn、NO2-、SO42-、Mn、F-、Hg。随着距离的增加,污染程度呈现衰弱的趋势。
major pollutants in soils surrounding a landfill of Guiyang City were analyzed, and based on that the pollution status was evaluated by means of Single Factor Pollution Index, Comprehensive Pollution Index and Nemerow Index. The result showed that soils along the groundwater flow have been contaminated by CODMn, NO2- , SO2/4- , Mn, F- and Hg, and the pollution degree declined with the increasing distance from the landfill.
