摘要

摘要: 为探究山地城市小流域的水环境问题，并寻求相应的治理对策。以某山地城市DS溪为研究对象，梳理了该流域的水质与水量特征及存在的水环境问题，得出DS溪上、中、下游的综合污染指数q_i分别为0.78、1.9、1.65，主要污染源为流域内的生活污水，最终进入污水厂的污水量约56万m³/a、地下水量约406万m³/a、截留的雨污混流水量约99万m³/a，还有约41万m³/a雨污混流水直接排入长江。基于上述分析结论及流域现存的水环境问题构建出以“山水引流—清污分流—生态修复—智能截流”为核心理念的山地城市流域水环境综合治理工程体系。此实例研究以期能为其他山地城市水环境治理提供参考，全面改善山地城市流域的水生态环境。

Abstract: To identify the water environment problems in small mountainous urban watersheds, this paper seeks appropriate solutions. By taking the DS Creek in a mountain city as an example, its water quality and quantity characteristics and corresponding environmental problems are studied. The results show that the comprehensive pollution index qi of the upper, middle and lower reaches of DS Creek is 0.78, 1.9 and 1.65, respectively. And the main pollutant is the discharge of sewage along the creek. Every year, it’s about 560 000 m~3 sewage water and 4.06 million groundwater that finally runs into the wastewater treatment plant, and about 990 000 m~3 mixed rainwater and sewage discharges into the Yangtze River. Based on the above analysis, a comprehensive water environment management engineering system in mountain urban watersheds is constructed with the core concept of “mountain water diversion-sewage diversion-ecological restoration-intelligent flow interception.” It is also expected that this case study can provide a reference for the water environment management of other mountain cities, and improve the water ecological environment as a whole.
