摘要
合流制管网溢流(combined sewer overflows,CSOs)是造成我国城镇地表水环境污染的重要原因。文中以广州市东山湖及其相关排水管网为研究对象,通过构建东山湖水动力、水质模型,模拟分析现状条件下CSOs对东山湖水质的影响,以及DN3000支隧建成后对东山湖水质的改善效果。结果表明,DN3000支隧对东山湖CSOs污染防治起到明显作用,该工程建成后,可以保证在典型暴雨时期,东山湖全水域内COD_(Cr)、TN、TP均可满足《地表水环境质量标准》(GB 3838—2002)Ⅳ类标准。
Combined sewer overflows(CSOs)is an important cause of urban surface water pollution at home.Dongshan Lake and the related drainage network in Guangzhou City were taken as the research object.By means of modeling of hydrodynamic and water quality models of Dongshan Lake,the impact of CSOs on the water quality under the current conditions was simulated and analyzed,and the improvement effect of DN3000 deep tunnel on Dongshan Lake water quality was also analyzed.Results showed that the DN3000 deep tunnel played an important role in the prevention and control of CSOs pollution in Dongshan Lake.After the completion of tunnel,COD_(Cr),TN and TP in Dongshan Lake could meet class Ⅳ standard specified in Environmental Quality Standard for Surface Water(GB 3838—2002)during typical heavy rainstorm period.
