摘　　要：随着社会发展进程的加快,人类生产、生活排放的污水日益增多,水体氨氮污染越来越严重。本研究对凯里市3个主要饮用水源进行3年的氨氮监测。结果显示,清水江氨氮浓度要比其他两地要高,其平水期氨氮浓度变化比较稳定,而枯水期和丰水期波动比较大;里禾水库枯水期和平水期氨氮浓度变化比较稳定,而丰水期波动比较大;金泉湖2014年和2015年氨氮浓度变化比较稳定,而2016年波动较大。根据《地表水环境质量标准》(GB 3838—2002)规定的地表水环境氨氮(NH_(3)-N)含量分级,凯里市主要饮用水源的氨氮环境质量主要为Ⅰ类和Ⅱ类,其中Ⅰ类占75.93%,Ⅱ类占24.07%。总体来看,凯里市主要饮用水源的氨氮环境质量优良。With the acceleration of the social development process,the sewage discharged by human production and life is increasing day by day,and the ammonia nitrogen pollution of water body is becoming more and more serious.In this study,three main drinking water sources in Kaili City are monitored for ammonia nitrogen for three years.The results showed that the concentration of ammonia nitrogen in Qingshui River was higher than the other two places,the change of ammonia nitrogen concentration in the normal water period was relatively stable,while the fluctuation is relatively large in the low water period and the high water period;the variation of ammonia nitrogen concentration in Lihe Reservoir was relatively stable in the low water period and the normal water period,but fluctuated greatly in high water period;the changes of ammonia nitrogen concentration in Jinquan Lake in 2014 and 2015 were relatively stable,while the fluctuation in 2016 was relatively large.According to the grading of ammonia nitrogen(NH_(3)-N)content in the surface water environment in the"Environmental Quality Standard for Surface Water"(GB 3838—2002),the environmental quality of ammonia nitrogen in the main drinking water sources in Kaili City is mainly ClassⅠand ClassⅡ,of which ClassⅠaccounts for 75.93%,and ClassⅡaccounts for 24.07%.Overall,the ammonia nitrogen environment quality of the main drinking water sources in Kaili City is excellent.
