摘　　要：在研究国内外有关雨水径流非点源污染研究成果的基础上,综述了城市道路、屋面、绿地雨水的水质特征及其影响因素,初期冲刷情况,以及初期雨水径流的截流控制应对方法。降雨的初期径流普遍有较高的污染物浓度,COD、TSS、TN、TP浓度值与城市污水浓度相近,截流处理这部分流量对保护水体环境意义重大。Based on the research of non-point source pollution caused by urban runoff at home and abroad , a summary was made on runoff quality characteristics , their influencing factors , first flush situation and the flow control of initial rainwater runoff of city roads , roofs and green lands.Generally , initial rainwater runoff has higher concentration of pollutants , while its concentration values of COD , TSS , TN and TP are similar to that of urban sewerage. It＇s of great significance for water environment protection to handle this part of the flow.
