| 摘 要： | 为了分析径流下渗系统在径流削减和污染控制方面的性能,本文对一个高速公路路面雨水径流下渗系统性进行了监测.结果表明,降雨量、径流量、径流削减量和径流排放量之间存在明显的正相关性(r=0.82～0.97,p0.05).该系统表现出高效的径流削减能力,当降雨量小于20 mm时,可以削减70%以上的径流量.与径流削减相比,该系统在污染物负荷控制方面更为有效.当降雨量在0～10 mm之间时,污染负荷的削减率几乎为100%;而当降雨在10～20 mm之间时,污染负荷的削减率仍然可以超过60%.相对总氮(TN)和总磷(TP)而言,下渗系统对悬浮物(SS)和化学需氧量(COD_(Cr))的去除能力要更高、更稳定.研究表明,径流下渗系统作为雨水管理的工具,在径流削减和改善水质方面具有良好的性能.

| Abstract: | An infiltration trench receiving highway stormwater was investigated to analyze its operational capacity both in runoff volume reduction and pollution elimination. It was detected that there are obviously positive correlations among rainfall, runoff, reduction and discharge volume (r=0.67~0.91, p<0.05). The system worked effectively in reducing the runoff volume by more than 70% for the storm events with rainfall less than 20 mm. Comparable with stormwater reduction, the system was more effective in reducing the pollutant load, almost 100% for the rainfall between 0 and 10 mm; while still over 60% for the rainfall between 10 and 20 mm. Among the pollutant parameters selected, SS and CODCr were highly and steadily reduced by the system compared to TN and TP. The findings have proven the capability of infiltration trench as a tool in stormwater management achieving both flow reduction and water quality improvement. |
