摘要
通过对清原县14个乡镇农村生活饮用水的水质分析,得出生活饮用水水质超标的指标有大肠菌群、菌落总数、铁、高锰酸盐指数,超标率分别为100%、100%、78.6%、7.1%。运用MapGIS和surfer软件绘图等值线图,模拟分析了水质污染物的空间分布特征,最后对研究区生活饮用水水质污染原因进行分析:人畜粪便、生活污水、生活垃圾等是水质污染的主要原因。
Through quality analysis of rural drinking water from 14 villages and townships in Qingyuan County,the indexes of exceeding standard have coliform group,total bacteria,Fe,permanganate index.the over standard rates are respectively 100%,100%,78.6%,7.1%.The contour map is drawn by using MapGIS and surfer software to analyze the spatial distribution features of pollutants.Finally,the causes of drinking water quality are analyzed.Animals and human beings excrete a domestic sewage,municipal solid waste,which is the main cause of water quality pollution.
