| 中文摘要 | 城市降雨径流产生的非点源污染是城市水污染的重要来源。该文以北京清华大学校园区为例,研究校园区的降雨径流污染特征及其对水体环境的影响。选取校园内道路、屋顶和绿地等不同的下垫面类型,采用天然降雨径流取样和人工降雨实验相结合的方式,对降雨径流的水质进行了化验分析,得到不同下垫面的降雨径流水质特性。结果表明:屋顶和道路径流以氮素污染为主,绿地径流以总磷TP和化学需氧量COD污染为主;通过降雨前后河道水质检测,分析了地表径流对河流水体环境质量的影响;最后对比分析了绿化屋顶和普通屋顶的径流水质表明,绿化屋顶具有较好的减污效果。; Urban rainfall-runoff pollution is a significant non-point source pollution for urban water bodies.The campus of Tsinghua University was taken as a case study in this research to analyze the characteristics of the rainfall-runoff pollution for a university campus.Runoff samples from the roofs,roads and grassland were tested that to study different underlying surface features.The results showed the runoff from roofs and roads had nitrogen as the major pollutant.The greenland runoff had TP and COD as the key pollution indicators.Comparison of the river water quality before and after rainfall showed the impact of the rainfall-runoff discharge on the river water environment.Green roofs gave more effective runoff pollution reduction than non-green roofs. |
