摘要
针对城市道路雨水径流瞬时汇集量大、污染负荷高的特征,设计了一种快速处理工艺并初步研究了该工艺对雨水径流负荷削减的效能。快速处理工艺包括初雨储存和旋流过滤两个过程。结合当地实际情况和相应的设计规范,设计的初雨储存池能有效储存初期道路径流。试验结果表明:旋流器主要去除SS,相应去除率为36%;而滤池能较为有效地去除各污染物,相应去除率:SS为95%、COD为50%、氨氮为80%、总氮为30%、总磷为70%。该快速处理工艺能有效控制道路雨水径流污染。
Aimed at the characteristics of large instantaneous volume and high-pollution load of urban road rainwater runoff, a new rapid treatment process was designed, and the reduction efficiency of rainwater runoff load in the process was investigated. The process includes two stages： first flush runoff storage and cyclone filtration. According to the local rainwater characteristics and the related design standard, the designed storage tank can store the first flush runoff effectively. The experimental results show that SS is removed mainly in the cyclone, with the con＇esponding removal rate of 36% , while pollutants can be removed by filtration, with the corresponding removal rates of 95% for SS, 50% for COD, 80% for NH3 - N, 30% for TN, and 70% for TP. The rapid treatment process can control the road rainwater runoff pollution effectively.
