摘　　要：从废水特点、水量和水质分析以及构筑物参数设计等方面,介绍了苏州某金属制品有限公司的废水处理整改工程。采用分类收集/分类处理、混合预处理、生化处理、末段加药的联合工艺处理金属制品废水。实际处理结果表明,出水COD≤50 mg/L,Cu^(2+)≤0.5 mg/L,Ni^(2+)≤0.1mg/L,Cr^(6+)≤0.1 mg/L,CN^-≤0.2 mg/L,Zn^(2+)≤1.0 mg/L,出水水质优于《污水综合排放标准》(GB 8978—1996)一级标准及《电镀污染物排放标准》(GB 21900—2008),含重金属污泥外委处理。The wastewater characteristics, quantity and quality as well as structure parameters, etc. for the wastewater treatment rectification project of a metal products company in Suzhou was intro- duced. The combined process of separate collection, classified preprocessing, complex pretreatment, bio- chemical treatment and end dosing was used to treat metal products wastewater. The actual result showed that effluent COD, Cu^2＋ , Ni^2＋ , Cr^6＋ , CN- and Zn^2＋ were less than 50 mg/L, 0.5 mg/L, 0.1 mg/L, 0.1 mg/L, 0.2 mg/L, and 1.0 mg/L respectively, which is better than both first grade of Integrated Wastewater Discharge Standard （GB 8978 - 1996 ） and Emission Standard of Pollutants for Electroplating （GB 21900 -2008）. The disposal of sludge containing heavy metal was entrusted to third parties.
