摘要
汾河流域水资源供需矛盾以及水污染日趋突出,已经成为制约汾河流域社会经济发展的主要因素之一。根据临汾市历年汾河流域水文水质资料,分别从计算原则、模型的确定、模型参数的设定、纳污能力统计与分析等方面对汾河流域13个水功能区进行纳污能力计算分析。其结果,各功能区COD和氨氮纳污能力分别为4180.70t/a和214.53 t/a;核定COD和氨氮限排总量分别为2480.91 t/a和172.91 t/a,均小于纳污能力。提出为保持水域功能,防止水体污染,需从源头对污染物的排放量进行控制。
The contradiction between supply and demand in water resources and water pollution in Fen river basin are prominent day by day,have become one of the key factors restricting social and economic development in the area.In this paper,the author,according to historical data in hydrology and water quality of Fen river basin in Linfen City,carried out calculation and analysis about loading pollutant capacity,respectively in calculation principles,determination of modal,setting of modal parameters,statistics and analysis in loading pollutant capacity,etc.,for 13 water function areas in the basin,The results is that COD,loading pollutant capacity in ammonia and nitrogen are respectively 4180.70 t/a and 214.53 t/a.The verified COD,loading total amount of pollutant discharge restricted in ammonia and nitrogen are respectively 2480.91 t/a and 172.91,both are less than those in the loading pollutant capacity.The author put forward that it is necessary for discharge of pollutant to be controlled at the source of water so as to maintain the function of waters and prevent pollution of water.
