摘 要:为研究菹藻浜宝山段河道污染负荷和污染物来源,利用2007—2011年菹藻浜宝山段河道污染源的水质数据,选取COD、NH3-N和总磷等作为典型水质指标,计算蕴藻浜COD、NH3-N污染负荷和各污染源贡献率。结果表明氨氮和COD为蕴藻浜宝山段河道主要污染类型;菹藻浜宝山段的COD、氨氮水环境容量分别为27149t/a、1357t/a,COD的削减量为-13218t/a,现状纳污量未超出水环境容量;氨氮的削减量为2175t/a,削减率为62%。上游和支流为菹藻浜宝山段河道主要污染源,上游对COD和NH3-N的贡献率分别为30.12%、36.23%,支流对COD和NH3-N的贡献率分别为54.36%和58.62%。To make clear the pollutant load and sources of Wenzaobang River in the Baoshan Region, five typical water quality indexes including COD, NH3 -N were selected. The rate of contribution from every pollution source and pollutant load of the Wunzaobang River according to the survey of pollution sources at Wenzaobang River from 2007 to 2011 were figured out. The results show that the main pollution source is from upstream and tributary. Wenzaobang River water environmental capacity of COD and NH3 -N is 27 149 t/a and 1 357 t/a. The reduction quantity of COD is - 13 218 t/a. As a result, permissible quantity of pollutants is lower than water environmental load. The reduction quantity of NH3-N is 2 175 t/a and reduction rate is 62 %. The upstream contributes 30. 12 % COD and 54.36 % NH3 -N while the tributary contributes 36.23 % COD and 58.62 % NH3 -N.
