摘要
以某水库为研究对象,研究单场暴雨条件下,串联式BMPs(Best Management Practices)应用于水库区域面源污染的控制研究。研究结果表明:串联式BMPs对洪峰流量有明显的削减作用,削减量达到80%,同时该系统对面源污染也有较好的控制作用,整个系统对TSS、BOD5和TN的去除效率分别为90%、74%和61%,其中滞留池对TSS有明显的去除效果,去除率可以达到60%以上,而湿地和缓冲草带系统则对BOD5和TN有较好的去除效果,去除率可达50～70%。
The control effects on non-point resource pollution combined with single rainstorm were studied at a reservoir by series of detention pond, wetland, dam and buffer strip. The results shows that about 80% rainstorm peak flow could be cut down when the runoff across the series BMPs. The detention pond is effective on the reduction of TSS which the removal rate is over 60% but have no obvious effect on the BOD5 and TN ,while the wetland and buffer strip can effectively remove the BOD5 and TN, the removal rate is about 50 - 70%. In the whole system, the removal rates of TSS, BOD5, TN were 90%, 74%, 61% respectively.
