中文摘要:
      雨水径流污染特征分析是海绵城市建设的基础支撑,同时可为城市水环境进一步改善提供助力。佛山新城是佛山市海绵城市建设实施方案重点区域之一,该文选取并收集其不同用地类型(住宅区、商业区、交通区、工业区等)、不同下垫面(地表、屋面、停车场等)降雨过程形成的雨水径流,分析污染特征。结果表明佛山新城雨水径流中地表径流中主要污染物为NH3-N、COD、SS,其中住宅区浓度最高,分别为 1.44 mg/L、85.2 mg/L、242 mg/L,交通区浓度最低,分别为0.6 mg/L、55.5 mg/L、115 mg/L,同时污染物浓度在降雨形成径流过程中很快就达到峰值,大多在径流初期10~20 min,具有明显的初期冲刷效应。
英文摘要:
      Analysis on rainfall runoff pollution characteristics is the support of sponge city construction, which also provides assistance for the city to further improve the water environment. The rainfall runoff data, collected from different land types (residential area, commercial area, traffic area, industrial area, etc.) and different underlay surfaces (surface, roof, parking lot, etc.) in Foshan new city, was detect the concentration of pollutants, and analysis the pollution characteristics. The result shows that the residential area is the highest concentration, and the traffic area is the lowest among the collected surface rainfall runoff formed by different land types. The main pollutants conclude NH3-N, COD, SS, which are within the range of 1.44-0.6mg/L, 85.2-55.5mg/L, 242-115mg/L respectively; The pollutant concentration reaches the peak quickly during the rainfall-runoff process, mostly in the early 10~20min, which shows pollution of rainfall runoff has obvious initial flushing effect.
