摘要
对洱海西部入湖河流白鹤溪主要排污口进行调查,采用等标污染负荷法对各个排污口排污情况进行分析。结果表明:白鹤溪在丰水期与枯水期等标污染负荷相当,南支的等标污染负荷大于北支,最主要的污染因子为总氮和总磷。白鹤溪最主要的排污口为南3排污口,其次为北2排污口,总氮总磷是其主要污染因子,高锰酸盐指数在北2排污口也占有较大比例。各个排污口的污染因子在丰水期与枯水期差异较大。以排污口形式进入白鹤溪的污染负荷是白鹤溪污染负荷的主要来源。
The main wastewater outlets at the western part inflow river of Erhai Lake,Baihe,were investigated,and the sewage condition of each outlet was analyzed by the equivalent pollution load method. The results showed as follows： The equivalent pollution load of flooding season is equal to that of the dry season,and the major pollutants were TN and TP. The main wastewater outlets at Baihe River were South 3 and North 2. The North 2 outlet presented higher value of permanganate index. The constituents of pollutants in each outlet were significantly different in flooding and dry season. Pollution load from wastewater outlets was a major form at Baihe River.
