摘要

经现场调查发现,四川省某县的生活垃圾填埋场,目前已发生渗滤液泄漏并对周边地下水产生污染。以高锰酸盐指数、NH_3-N、Cl~-、SO_4~(2-)、Fe~(2+)、Mn~(2+)、TDS和总硬度等8个指标为对象,采用F值指数法和主成分分析法并结合地下水化学分析对周边10个采样点的地下水水质进行综合评价,并用ArcGIS 10.3对污染物浓度进行插值,分析不同种类污染物在场地附近的浓度分布特征。评价结果表明:填埋场周边地下水已受到严重污染,综合评分F值均>7.20,属于极差级别,整体上,2种评价方法所得不同采样点污染程度排序结果基本一致,埋场下游方向越近污染越严重,主要污染物为Cl~-和SO_4~(2-),污染较重的采样点的地下水化学类型也相应的由HCO_3-Ca型转变为了HCO_3·Cl-Ca和SO_4-Ca 2种类型。研究表明,该文采用的水质评价模式可用于污染地下水水质评价,并能对评价结果给出合理解释。
        After the site investigation, it is found that the municipal solid waste landfill of a county located in Sichuan Province has produced leachate leakage, thus the surrounding groundwater was polluted. Taking 8 indicators such as COD_(Mn), NH_3-N,Cl~-, SO_4~(2-), Fe~(2+), Mn~(2+), TDS and total hardness as object parameters, F value index and the principal component analysis combined with groundwater chemical analysis were used to evaluate the quality of surrounding groundwater at 10 sampling sites comprehensively. The results of the evaluation show that the groundwater around the landfill has been seriously polluted, and the comprehensive rating F value is greater than 7.20, which belongs to the extremely poor level. On the whole, the results of the pollution degree of different sampling points obtained by the two evaluation methods are basically the same. The closer the downstream direction of landfill is, the more serious the pollution is. The main pollutants are Cl~-and SO_4~(2-)and chemical types of groundwater with heavy pollution are also changed from HCO_3-Ca to HCO_3·Cl-Ca and SO_4-Ca. The research shows that the water quality evaluation model adopted in this paper can be used to evaluate the quality of polluted groundwater and give a reasonable explanation for the evaluation results.
