摘　　要：对长春市某大学校园不同途径的雨水水质进行监测的基础上,研究分析了园区降雨过程中不同下垫面的污染情况和各项水质指标变化规律。结果表明:由于下垫面材料污染程度、路面材料、路面污染状况、周边大气环境质量等因素影响使不同下垫面的雨水都会受到不同程度的污染,其主要污染物为COD、悬浮性固体(SS)、氨氮、TP等;随着累积雨量的增加,最终均趋向逐渐减小的规律;路面雨水比屋面雨水污染严重;初期雨水污染情况较严重,后期雨水水质较好。根据研究的雨水水质情况确定后续雨水回用技术及处理工艺,以此缓解水资源短缺和水质污染的问题。The pol lut ion si tuat ion of di f ferent under lying surface and the change rule of each water qual i ty index were researched, on the basis of rainwater quality monitoring by different approaches in a university campus . The results showed that due to some factors, such as the underlying surface material pollution, road materials, road surface pollution condition and surrounding atmospheric environment quality, the pollution of different underlying surface rainwater would be different. Main pollutants of rainwater runoff in the city campus area were such as C0D, SS, NH^ N, TP and etc. Ultimately, along with the increase of accumulated rainfall, the pollutants tended to gradual ly decrease. The road rain pollution was more serious than roof runoff pollution and the early rain pollution was serious, but the late rain water quality was much better. According to the rainwater conditions, subsequent rainwater recycl ing technology and processing technology were determined as a way to al leviate the problem of water shortage and water pollution.
