摘要
研究城市雨水径流水质的变化规律可为城市雨水资源利用提供科学依据。通过对保定市区2010年6到9月份7场降水的雨水水质和不同路面径流水质进行监测，发现了雨水及路面径流污染物浓度随着降水时间呈下降趋势，降水水质及路面径流水质的各项污染物指标之间存在相关性显著的线性关系，路面径流SS浓度与产流量之间存在相关性显著的对数关系。依据饮用水卫生标准和城市杂用水卫生标准对不同路面径流水质进行了单因子评价，表明城市路面雨水径流可用于绿化、冲厕、消防、建筑施工和洗车等方面。
Study the changing rule of water quality on rain and runoff in urban area may offer scientific support for the utilization of rainwater re-sources. Through monitoring the water quality of rainfall water and runoff produced on different road surface in seven events of precipitation during June and September in 2010, we found that pollutant concentration showing a downward trend as the time of rain going, and there exists a fine correlation in different index of water quality both in rain water and road surface runoff. Moreover, there exists a good correlation be-tween concentrate of SS and runoff depth at the surface of concrete road. Finally, in accordance with water quality standards for drinking and for urban water consumption, we evaluated water quality of different road runoff, which showed that urban road runoff can be used for landsca-ping, washroom flushing, fire fighting, construction and car wash.
