摘　　要：某纺织公司由于印染废水产生量的增加和其中难降解有机物浓度的升高，现有废水处理系统的出水COD高达200～350mg／L，不能满足《纺织染整工业水污染物排放标准》（GB4287-92）的一级标准要求，为此提出增加厌氧酸4L／生物接触氧化／沉淀工艺对现有出水进行深度处理。结果表明，经新增工艺深度处理后，出水COD可稳定维持在100mg／L以下，达到了GB4287-92的一级标准．并且新增工艺可最大限度地利用现有处理工艺，具有工程应用的可行性。Due to increase of printing and dyeing wastewater volume and refractory organic concentration, the effluent COD from the existing wastewater treatment system in a dyeing and textile factory is up to 200 to 350 mg/L, which does not meet the first grade criteria specified in the Discharge Standard of Water Pollutants for Dyeing and Finishing of Textile Industry （ GB 4287 - 92）. Therefore, the combined process of anaerobic acidification/biological contact oxidation/sedimentation was added. After the advanced treatment with the new combined process, the effluent COD can be maintained below 100 mg/L, which meets the first grade criteria specified in the Discharge Standard of Water Pollutants for Dyeing and Finishing of Textile Industry （ GB 4287 - 92）. The new combined process can make full advantage of the existing facilities.
