澄碧河水库流域污染负荷估算

Estimation of pollution load in Cheng Bi River Reservoir Basin

运用统计数据以及排污系数法对澄碧河水库流域范围内工业、生活、农业面源、畜禽水产养殖、旅游污染负荷进行全面估算,确定流域的主要污染源。结果表明,澄碧河水库流域范围内主要污染源为农业面源污染,其次是生活污染源和畜禽养殖污染源,2015年主要污染物COD、氨氮、总氮、总磷的入库量分别为:5314.32t、177.13t、386.48t和35.52t。

Using the statistical data and discharge coefficient to conduct a comprehensive estimation of pollution load from industry, domestic sewage, agriculture non-point source,livestock, aquaculture,tourist industry in ChengBi River Reservoir Basin. The results indicated the water pollution in ChengBi River Reservoir Basin was mainly contributed by agriculture non-point source, secondly contributed by domestic sewage and livestock feces pollution.5314.32tons of COD,177.13tons of NH3-N,386.48tons of TN and 35.52tons of TP was discharged into ChengBi River Reservoir Basin in 2015.
