| 摘 要： | 随着城市点源污染控制程度的提高,雨水径流引起的面源污染日益突出。本文在对上海市临港不同功能区降雨径流水质监测的基础上,计算了地表径流污染负荷并对径流初期效应进行了研究。结果表明:TN、TP、CODMn径流水质变化范围分别为0.03～52.27、0.01～18.85、27～111.16 mg/L。不同功能区路面径流水质污染程度由大到小顺序依次为:交通区>商居混合区>文教区;屋面径流水质污染程度由大到小顺序依次为:商居混合区>文教区。文教区路面径流年污染负荷最低,商居混合区屋面径流年污染负荷最高,TN、TP、CODMn年污染负荷分别为11.16、1.03、33.33 kg/(hm2·a-1);31.49、5.61、172.87 kg/(hm2·a-1)。经M(V)曲线及b值法分析,在大部分降雨事件中,路面径流初期效应较明显,而屋面径流的初期效应较微弱。

| Abstract: | With the stricter control of point source pollution,non-point source pollution caused by rainfall runoff is paid more and more attention.The pollution load and the first flush effect of urban runoff were analyzed on the basis of stormwater runoff analysis.The results reveal that the concentration fluctuation of TN,TP and CODMn for the urban runoff are 0.03~52.27,0.01~18.85 and 0.27~111.26 mg/L respectively.In road runoff,the pollution of different functional areas followed the sequence of traffic area>comme... |
