| 摘 要： | 以前湖校区为研究对象，以润溪湖为受纳水体，通过对路面雨水径流及湖水在雨前、雨中、雨后的水样进行pH、浊度、SS，COD，TP和氨氮指标测试，探究各项污染物浓度在三个阶段的变化规律，对水体水质作了综合评价，进行受纳水体污染物浓度增加值与雨水径流水质相关性分析。结果表明:雨水径流的汇入，使受纳水体的pH有所降低、其余5项指标浓度均有所增加，水质类别从Ⅳ类水增加到Ⅴ类水，相关性分析结果显著，说明雨水径流的汇入是造成水体污染物增加的主要原因，显著性相关回归方程可用于推算该区域内受纳水体污染物的增加量，预测水体污染程度。并提出了相应的建议，为解决由城市雨水径流所引起的非点源污染问题提供理论参考依据。

| Abstract: | Taking Qianhu campus as the research site and Runxi lake as the receiving water, we tested pH, turbidity, SS, COD, TP and ammonia nitrogen of road rainwater runoff and lake water to explore the changes of the concentration of pollutants before the rain, during the rain occurrence and after the rain. Correlation analysis between the concentration increase of pollutants in the receiving water body and water quality characteristics of rainwater runoff was performed to determine the characteristics of the receiving water body polluted by city rainwater runoff. The results showed that pH reduced but the others indicators increased and water quality characteristics varied from Type Ⅳ to Ⅴ of the surface water standard because of rainwater runoff, and the regression equation can used to calculate the increment of pollutants in the receiving water body with significant correlation. Responsible recommendations were suggested to provide theoretical reference basis to solve the problem of non-point source pollution caused by rainwater runoff of the city roads. |
