不同行政区入秦淮河污染物通量分担率研究
|
摘要
为研究秦淮河流域各行政区入秦淮河的污染物通量分担率,基于一维平原河网水环境数学模型,模拟了2016年受沿河支流及排污泵站影响的主要入河的污染物(NH3-N、TP)通量。结合实测和计算结果,量化分析了控制单元及全流域内各行政区对主要入河污染物通量的分担率。结果表明,秦淮河流域内各行政区对国考七桥瓮断面主要超标因子的分担率为:秦淮区的NH3-N平均分担率为12%、TP平均分担率为13%;雨花台区的NH3-N平均分担率为20%、TP平均分担率为15%;建邺区的NH3-N平均分担率为2%;江宁区的NH3-N平均分担率为55%、TP平均分担率为53%;溧水区的NH3-N平均分担率为1%、TP平均分担率为2%;句容市的NH3-N平均分担率为10%、TP平均分担率为17%。
In order to study the pollutant flux sharing rate of different administrative areas in the Qinhuai River,the pollutant flux of the main pollutants( NH3-N and TP) into the Qinhuai River influencing by the tributaries and sewage pumping stations in 2016 were simulated based on the one-dimensional plain river network water environment mathematical model. Combined with the measured and calculated results,quantitative analysis of the pollutant flux sharing rate of different control units and administrative areas in the whole basin was carried out. The results show that the pollutant sharing rates of different administrative areas in the Qiqiaoweng section are as follows: the average sharing rates of NH3-N and TP of Qinhuai District are 12% and 13%,respectively; the average sharing rates of NH3-N and TP of Yuhuatai District are 20% and 15%,respectively; the average sharing rate of NH3-N of Jianye District is 2%; the average sharing rates of NH3-N and TP of Jiangning District are 55%and 53%,respectively; the average sharing rates of NH3-N and TP of Lishui are 1% and 2%,respectively; the average sharing rates of NH3-N and TP of Jurong City are 10% and 17%,respectively.
