摘要
作为水库上游河道,沙湾河内水污染情况直接影响下游水库水质。本文梳理了沙湾河水质污染现状情况,进行了已建工程的评估分析,继而开展沙湾河流域在无降雨时、降雨时两种基本工况下的水质污染分析。结果显示,雨水径流污染浓度随着降雨量的增大而逐步下降,据此提出了考虑不同降雨条件下河流水质差异而进行分质处理的水质保障策略。
As an upstream channel of Shenzhen reservoir,water pollution in Shawan River directly infect the water quality in downstream reservoir.In this paper,the water pollution situation and the existing engineering in Shawan River was concluded,and the pollution analysis under the case of rainfall and no-rainfall was carried out.Results showed that,the pollution density of rainfall runoff declines with the increase of precipitation.Then the water quality protection strategy of Shawan River considering different precipitation levels was suggested.
