徐州市固废填埋场地下水环境质量分析研究

Analysis and research on the quality of groundwater in thesolid waste landfill sites in Xuzhou

通过对徐州市4座生活垃圾填埋场和1座危险废物填埋场区域地下水水质监测结果分析,运用单因子指数法、污染物负荷占比法和内梅罗指数法对地下水水质进行评价。结果表明,水质在良好与较差之间,水质由优到劣分别为D场、B场、W场、A场和C场。5座固废填埋场地下水的总硬度、可溶性总固体、挥发性酚类和氟化物污染负荷占比均较高,A场砷元素、W场铅元素超过地下水Ⅲ类水,具有一定的污染特征性。

in this article,we assessed the groundwater quality of 4 domestic waste landfills and 1 hazardous waste landfill in Xuzhou City based on monitoring results by single factor index method,pollutant load percentage method and Nemerow index method. The results show that the water quality is between good and poor,and the quality from good to bad is in the order of field D,B,W,A,and C. The total hardness,total soluble solids,volatile phenols and fluoride were higher proportion of pollution index in all of the 5 solid waste landfill sites,and the arsenic element of A field and the lead element of W field exceeded the Ⅲ level threshold of groundwater quality,which exhibited certain pollution characteristics.
