摘 要: | 为研究城市下垫面径流的水文过程与污染物浓度变化特征,对济南市2007年4~10月的6场降雨进行路面和屋面水文、水质过程同步分析,结果表明,济南降雨屋面的径流系数在0.80~0.96之间;路面的径流系数在0.88~0.96之间;径流曲线的形态与降雨过程线类似,但波动幅度相对较小;济南市降雨径流初期污染严重,降雨后期氨氮浓度稳定在2~4mg/L,屋面径流的CODcr、SS浓度分别维持在20mg/L和50mg/L以下,路面的CODcr浓度维持在50mg/L左右,但SS浓度较大;雨水径流中的CODcr与其他污染物之间的确定系数R2均大于0.8,污染物间较小的相关斜率表明了各污染物间良好的线性相关关系。

Hydrology and Pollution Characteristics of Urban Runoff in Jinan |
| |
Abstract: | Samples were collected in 4 rainfall events in Jinan from May 2007 to Aug 2007.The purpose of this study is identification and characterization of hydrological process of urban runoff, as well as concentration variation of pollutants variation of pollutants in it .Hydrology and pollution of the rainfall-runoff process were analyzed on roof and road. Study results show that runoff coefficients of roof are 0.80~0.96, while 0.88~0.96 of road in Jinan. The shapes of hydrological curves of runoff are similar to rainfall curves but a milder tendency. The research that calculated the correlation between the slope of the pollutants come to the rainwater runoff of pollutants.So can have a detection of COD and SS and other major pollutants of storm water runoff in Jinan city to represent contents of other pollutants, greatly simplifies the rain run-off water quality testing and quantitative analysis. |
