摘要:根据实地调查情况选取代表性地下水井,利用单因子达标评价和水质综合评分值F法对吉首市地下水进行了水质监测与评价.结果表明,该市地下水中的大肠菌群超标较为普遍,氨氮、亚硝酸盐部分水井有超标现象出现,锰等重金属因子所有水井均未超标;从综合污染指数来看,位于居民集中区的地下水井的平均综合指数高于污染监控井,说明吉首市地下水质量受生活污染较工业污染更为严重.

Abstract: Water quality monitoring data by field investigation of the representative groundwater wells was evaluated by using single factor evaluation and comprehensive evaluation F method.The results showed that in most wells the indexes of coli forms exceeded the standard level,in some wells the indexes of ammonia nitrogen and nitrite exceeded the standard level,and in all wells in the indexes of heavy metals such as manganese did not.Average comprehensive indexes of the groundwater in residential areas were higher than those in pollution monitored areas,which indicates that the groundwater quality in Jishou was mainly polluted by domestic pollution.
