摘　　要：为研究工业污水处理厂对地下水水质的影响,选取六安市5个工业污水处理厂为研究对象,通过对其地下水水质的分析测试,采用单因子评价法和内梅罗指数法对地下水进行了质量评价。结果表明,污水处理厂地下水水质总体较好,水质超标点位基本位于污水处理厂地下水检测点。单因子评价结果中Ⅱ、Ⅲ、Ⅳ、Ⅴ类水的样本数分别占样品总数的32%、36%、20%和12%,无Ⅰ类水;内梅罗指数法评价结果中Ⅰ、Ⅱ、Ⅴ类水的样本数分别占样品总数的76%、16%和8%。地下水中氟化物、氨氮、铜、砷、硫酸盐、氯化物、硝态氮、COD、锌和钠均受到污水处理厂的影响。In order to study the impact of industrial sewage treatment plant on groundwater quality,five industrial sewage treatment plants in Lu'an City were selected as the research objects.Based on the test results of groundwater samples,single\|factor evaluation method and Nemerow index evaluation method were used to evaluate the quality of groundwater.The results show that the groundwater quality of the sewage treatment plant is generally good,and the over\|standard points are basically located at the groundwater detection point of the sewage treatment plant.According to the single\|factor evaluation results,the number of samples of gradesⅡ,Ⅲ,Ⅳ,and V groundwater in the total number of samples account for 32%,36%,20%and 12%,respectively,without grade I groundwater.The results of the Nemerow index evaluation method show that the number of samples of gradesⅠ,ⅡandⅤgroundwater in the total number of samples account for 76%,16%and 8%respectively.Fluoride,ammonia nitrogen,copper,arsenic,sulfate,chloride,nitrate nitrogen,COD,zinc and sodium in groundwater are all affected by the sewage treatment plant.
