- Abstract:
- Surface runoff pollution, as a typical non-point source, has become one of the dominating external causes of black and odorous water and the key to pollution control now. In combination with the comprehensive environment improvement project of Wanjia Lake in Wuhan, runoff pollution control scheme is introduced based on the thorough background investigation. First-flush storage and emergency treatment are adopted to control the point pollution. The mixed sewage in the dry season and the first-flush runoff are stored in the storage tank, and lifted to the municipal sewage treatment system by pump. In order to control the non-point pollution along the lake, shallow wetland plant belt and ecological buffer zone are used for bioretention against pollutants, which could reduce the pollution load discharged into the core lake. The comprehensive environment improvement project of Wanjiahu lake has passed the inspection of local environmental protection department, and the water quality has gradually moved from stable level Ⅴ to level Ⅳ.
