为了探讨雨水水质对雨水利用工程的影响，以沈阳市浑南新区的雨水水质为研究对象，对单体建筑屋面、小区径流及市政排出口的雨水进行为期一年的检测与分析．研究结果表明，影响雨水水质的主要污染物是COD和SS，特别是在降雨初期比较明显，随着降雨时间的延续，水质逐渐好转．市政排出口雨水COD和SS的含量最高，变化范围分别为167～249，119～332 mg/L，小区径流雨水COD和SS的变化范围分别为27～85和106～269 mg/L，建筑屋面雨水COD和SS的变化范围分别为15～80和50～153 mg/L．3个取样点的氨氮含量分别为1．7～5．2，3．7～18．2和5．2～25．6 mg/L．

To explore the influence of rainwater quality on rain utilization projects the rainwater of building roofs community runoff and municipal outlets which were taken from Hunnan New District of Shenyang was detected and analyzed for one year. The results show that the main pollutants affecting the quality of the rainwater are chemical oxygen demand COD and suspended solids SS which is especially obvious at the beginning of rainfall. With the duration of the rainfall water quality improves.The contents of COD and SS in municipal outlets are the highest which are 167 to 249 mg/L and 119 to 332 mg/L respectively. The contents of COD and SS are 27 to 85 and 106 to 269 mg/L in community runoff 15 to 80 and 50 to 153 mg/L in the rainwater of building roofs.NH4+-N concentrations of the three sampling sites are 1.7 to 5.2 3.7 to 18.2 and 5.2 to 25.6 mg/L.
