摘　　要：汽车整车制造厂涂装废水具有水质复杂、水质波动大,水量大等特点,其中磷化废水含有重金属镍是国家严控的第一类污染物质,如处理不当必然会对人类生存及生态环境造成严重危害。本文阐述了通过二级化学+混凝沉淀工艺处理磷化废水,出水水质达到《水污染物排放限值》(DB44/26-2001)第二时段三级标准。The coating wastewater of automobile manufacturers has the characteristics of complex water quality, large fluctuations in water quality, and large water volume. Phosphating wastewater containing heavy metal nickel is the first type of pollutants strictly controlled by the country. If it is not handled properly, it will inevitably cause serious harm to human survival and the ecological environment. This article describes the treatment of phosphating wastewater through the second-level chemical + coagulation and precipitation process, and the effluent quality reaches the third level of the second period of "Water Pollutant Discharge Limit"(DB44/26-2001).
