摘　　要： 针对云南省星云湖湖水排放对下游饮用水源地抚仙湖水质的污染日趋严重的问题,采取湖水出流改道措施,改变湖水流向,隔断上游污染,出流改道后的富营养化湖水经生态净化后排放备用水源地。生态净化工程处理规模为20×104 m3/d,主要采用稳定塘/碎石床湿地组合工艺,星云湖原劣Ⅴ类水经生态净化后达到Ⅲ类水质标准。该工程一年多的运行表明,出水水质基本达到设计要求,对保护水源地水质起到巨大作用,也为我国高原湖泊富营养化湖水的治理提供了示范和参考。 Due to downstream discharge of the polluted outflow from Xinyun Lake in Yunnan, the serious water pollution problem of Fuxian Lake has come out. The outflow diversion was taken to change the Xingyun Lake water stream and separate the upstream pollution. The Xingyun Lake water is purified by ecological engineering and then discharged to the spare drinking water source. The treatment capacity of ecological engineering is 20 × 10^4 m^3/d, and the combined process of stabilization ponds and stone wetland is used. After the ecological purification, the quality of Xingyun Lake water is changed from V class to Ⅲ class of the water quality standard. The effluent quality meets the design requirements in more than one year. The ecological engineering plays an important role in protecting drinking water quality and provides demonstration and reference for plateau lake eutrophic water treatment in China.
