摘要
介绍了汾河太原城区段的水质现状,对主要断面的一些常规污染指标进行了长期监测,结果表明:NH3 -N和硫化物超标严重,在枯水期更为甚之,这是导致河水发生黑臭的根源;年内径流分配极不均匀、枯水期流量小是导致河流水质恶化的主要原因。最后给出了防治汾河水污染的措施。
Introduction is given to the current water quality in Taiyuan reach of the Fenhe River, and monitoring was conducted for a long period on the regular indexes of main section. The result shows that NH_3-N and sulfide surpass seriously the standard, and it is even more in rate dry season. Extremely uneven runoff distribution in a year and low water flow in dry season are causative of deterioration of the river water. Finally, the preventive measures are proposed for pollution of Fenhe River water.
