| 摘 要： | 基于对广东珠海城区暴雨径流污染的监测,引用SCS模型对城区暴雨径流污染负荷进行估算并分析评价。结果表明,珠海城区暴雨产流年平均1529.2mm,其中以交通主干道和商业区径流量最大。暴雨径流污染物浓度水平较高,T—N,T—P,COD_(Cr)和BOD_5负荷总量分别为765.27,74.06,11 958.94和1104.71t,其中COD_(Cr)负荷为工业点源污染的72.32％,占珠海非点源污染总负荷的24.69％。暴雨径流在雨后短时间内会使受纳水体的水质迅速恶化。因此,珠海城区暴雨径流对水环境的威胁较大。

| Abstract: | Based on monitoring of pollutants in urban storm runoff in Zhuhai city, pollutant loads are calculated with the SCS hydrologic model, and the results of the calculations are considered. The results show that the annual mean value for runoff is 1529. 2 mm, with of the highest values coming from traffic roads and commercial districts. The concentration of pollutants is high in the urban storm runoff. The pollutant loads for T-N.T-P, CODCr and BOD, are 765. 27, 74. 06, 11958. 94 and 1 104. 71 t respectively. CODCr accounts for 72. 32 percent of the pollutant load from industrial point sources(PS) and 24. 69 percent of the load from non-point sources. Urban storm runoff makes water quality worsen rapidly within short time after rain. Consequently, urban storm runoff has a large impact on the water environment. |
