为了控制和降低银川地区潜水污染的程度,根据银川地区2010年枯水期潜水水质监测资料,采用《城市环境水文地质工作规范》（DZ 55-87）规定的综合污染指数法为地下潜水污染评价方法,以潜水环境背景值（污染起始值）为评价标准,选取氯化物、硫酸盐、氟化物、砷、锌、铬（六价）、矿化度、总硬度、氨氮、硝酸盐、亚硝酸盐、总铁、锰等13项指标作为评价因子进行综合评价,根据污染指数将研究区划分为未污染、轻度污染、中度污染和重度污染4个等级评价区;并对原因进行分析,最后,提出地下潜水污染防治对策.

In order to control and reduce the level of phreatic pollution in Yinchuan area,according to the monitoring data of phreatic in dry season in 2010,using ＂urban environment hydrogeology norms＂（DZ55-87） provided comprehensive pollution index as evaluation method of underground water pollution,by 13 phreatic environmental background values（starting pollution value） as an evaluation factor for a comprehensive evaluation,include evaluation criteria,chloride selecting,sulfate,fluoride,arsenic,zinc,chromium（hexavalent）,salinity,total hardness,ammonia,nitrate,nitrite,total iron,and manganese,and according to pollution index,phreatic pollution is divided into four types,no pollution,slight pollution,moderate pollution and severe pollution,and the causes of phreatic pollution is analyzed.Finally,prevention measures of phreatic pollution are proposed.
