城市封闭性黑臭水体综合治理方案

Scheme of Comprehensive Treatment for Urban Enclosed Black and Odorous Water Body

由于城市化进程的迅速发展,城市水体的黑臭趋势不断加剧,城市水环境治理迫在眉睫,势在必行。文中以治理合肥市大蜀山森林公园南湖为例,在海绵城市建设、黑臭水体治理、生态系统构建等技术路线的指导下,通过对南湖水质污染成因的分析,针对性地采用污水截流、雨水收集处理系统、生态清淤、生态系统构建等技术措施,有效控制并削减了入湖污染物浓度,恢复了多样性生态系统,南湖水质得到明显改善。除此之外,南湖水环境的有效治理为其他城市封闭性黑臭水体治理提供了宝贵的研究思路和成功的借鉴。

With the rapid urbanization,cities are facing big challenge to deal with the deteriorate black-odorous water environment.Treatment of South Lake of Dashushan Forest Park in Hefei City is taken as an example in this study.Under the guidance of sponge city construction,black and smelly water treatment,ecosystem construction and etc,the causes of water pollution are analyzed,and targeted treatment measures such as sewage interception,rainwater collection and treatment system,ecological dredging and ecosystem construction are taken to treat the black-odorous water.Results show that the input water pollutants are effectively controlled and reduced,and diversity ecosystem is restored,and consequently water quality is significantly improved.Present case provides valuable research ideas and references for the treatment of other closed black-odorous water.
