摘要
分析比较了国内外屋面径流水质的研究情况,结果显示,屋面径流水质存在较大的污染性,而且我国的屋面径流污染比一些发达国家的屋面径流污染明显严重。屋面径流水质主要受降雨量、降雨强度、屋面材料、季节和气温的影响。讨论了屋面径流的几种利用方案,主要包括纳入中水系统、独立的雨水利用系统、屋面绿化利用系统和渗透回灌系统。
By analyzing studies on urban roof runoff at home and abroad, it was found out that the runoff water was badly polluted, especially in China. Roof runoff water quality was affected by rainfall, rainfall intensity, roof material, season and air temperature. Some utilization projects of roof runoff water were also discussed including bringing it into normal water system, independent rainwater utilization system, roof virescence system and infiltration and irrigation system.
