【摘要】 为了全面、准确、客观分析庆安县新建水源地的水质状况,采用改进综合污染指数法为主,单项指数法、内梅罗指数法为辅进行了水质评价。结果表明,研究区浅层地下水普遍受到污染,Fe、Mn、氨氮、亚硝酸氮为主要污染物。分析了水质污染的原因,Fe、Mn因子超标属于原生地质环境问题,氨氮、亚硝酸氮因子超标属于人为原因。需对拟建水源地污染物进行处理才可能达到生活饮用水标准。更多还原

【Abstract】 In order to comprehensively,accurately and objectively analyze the water quality status of new water source of QingAn county,the improved comprehensive pollution index method is used as the main method with the Single index method and Nemerow index method as assistant method to evaluate the water quanlity.The result shows that the shallow groundwater area has been generally polluted with Fe,Mn,Ammonia nitrogen,Nitrite nitrogen as the main pollutants.The analysis of reasons for water pollution indicates that problem of Fe,Mn factor overweight belongs to the original geological environment problems;the problem of Ammonia nitrogen,Nitrite nitrogen factor overweight belongs to human reason.The water quality of proposed new water source can reach the drinking water standard only when the pollutants are treated.更多还原
