Abstract ㊀With 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 targe-ted treatment measures such as sewage interception,rainwater collection and treatment system,ecological dredging and ecosystem con-struction 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.Keywords ㊀enclosed black and odorous water body㊀source control and sewage interception㊀ecological sediment dredging㊀ecosys-tem construction
