摘　　要：采用单因子指数法、内梅罗污染指数法和加拿大水质指数法,综合评价了沈阳水务集团三水厂张官9号水井、杨官1-2、杨官4-2、杨官5-1、杨官6-1水井水质,选择氨氮、硫酸盐、氯化物、耗氧量、总硬度、铁、锰7项指标作为评价因子。结果表明:张官9号水井、杨官1-2、杨官4-2、杨官5-1、杨官6-1水井水质指标均符合要求。张官、杨官地下水中总硬度较高。张官9号水井水质逐年变好;杨官6-1水井水质较稳定,2017—2019年期间水井水质没有明显变化。根据评价结果可以得出,污染情况最严重的指标对单因子指数法和内梅罗污染指数法的评价结果影响较大,而加拿大水质指数法是一种较为综合的水质评价方法。Single factor index method,Nemero pollution index method and Canadian water quality index method were used to comprehensively evaluate the water quality of Zhangguan No.9,Yangguan No.1-2,Yangguan No.4-2,Yangguan No.5-1 and Yangguan No.6-1 wells in the third Water works of Shenyang Water Group.Seven indexes of ammonia nitrogen,sulfate,chloride,oxygen consumption,total hardness,iron and manganese were selected as evaluation factors.The results show that the water quality indexes of Zhangguan No.9,Yangguan No.1-2,Yangguan No.4-2,Yangguan No.5-1 and Yangguan No.6-1 wells all meet the requirements.However,the water hardness of groundwater in Zhang Guan and Yang Guan is higher.The water quality of Zhangguan No.9 well is getting better year by year;the water quality of Yangguan No.6-1 well is relatively stable,and there is no obvious change in well water quality from 2017 to 2019.According to the evaluation results,it can be concluded that the index with the most serious pollution has a great influence on the evaluation results of single factor index method and Nemero pollution index method,while the Canadian water quality index method is a more comprehensive water quality evaluation method.
