| 摘 要： | 国外对城市降雨径流污染进行了研究,国内也有文献报道。夏青提出了模拟径流污染对受纳水体影响的点源、非点源污染分别计算然后线性叠加的近似方法。但是,对城市整体径流污染对河流影响的系统模拟还处于探索阶段,并有许多未真正解决的问题。因此,必须确定因分散排放经不同长度河段到总排放口的污染物衰减量,即径流排放的污染物浓度取值等问题。我们对这些问题的解决和实现作一初步的偿试。

| Abstract: | The runoff pollution of rivers within urban area and their down streams was simulated using a method overlaying both point and non-point sources. Runoff discharges have been converted into a discharging outlet by means of concentration decrease. The results indicated that BOD contribution from non-point sources to rivers in urban area of Chengdu consists of 37.5-82.6% of the total. A typical runoff rush on river spreads about 18 km downstream and lasted 8.2 hours. |
