Black smelly water around the economy, society and people’s livelihood development has a very bad influence, seriously affects people’s production and life style, in order to further remove black smelly water bodies, this article takes the water environment treatment scheme of Houhai River in Nanshan District of Shenzhen as an example, this paper considers the treatment of water environment as a whole with systematic thinking. On the basis of in-depth analysis of the sources of pollutants in the basin, the quantitative analysis method of current pollutants in the present situation was established, and a technical route of “pollution control and interception, endogenous treatment, ecological restoration and raising quality of living water” was established according to the quantitative analysis of pollutants. In the process of treatment, the concept of sponge city should be implemented simultaneously; the river ecosystem should be improved by revetment ecological promotion, drainage outlet landscape treatment and so on. The implementation effect evaluated by model showed that all indicators could reach the design goal. The purpose of this paper could provide reference for water environment treatment schemes in other similar areas.
