摘　　要：针对造纸化学品生产废水具有成分复杂,可生化性差,有机物、NH3-N、Cl-浓度高的特点,采用"初沉池-悬浮生物滤池(A/O)-混凝沉淀池-催化氧化池-硝化滤池"组合工艺对造纸化学品生产废水进行了中试研究,取得很好的处理效果。结果表明,在进水COD为4 832～12 846 mg/L,NH3-N为39～430 mg/L,Cl-为3 200～15 000 mg/L的情况下,处理后出水COD小于500 mg/L,NH3-N小于35 mg/L,主要指标达到污水综合排放标准(GB 8978-1996)三级标准。Based on the characteristics of complicated composition, low biodegradability, high concentra-tion of organic compounds, high ammonia nitrogen and high chloride ion of wastewater from the factory producing paper chemicals,the method of＂ primary settling tank-suspended biological filter （A/O）-coagulation sedimenta-tion tank-catalytic oxidation tank-nitrification filter＂was used in the treatment of paper chemicals wastewater in pilot research, and good results were achieved. The results indicated that after being treated by the combined process, the effluent COD and NH3-N of water was less than 500 mg/L and 35 rag/L, under the conditions of the content ranges of COD, NH3-N and Cl^- of 4 832 - 12 846 mg/L, 39 - 430 mg/L and 3 200 - 15 000 mg/L, re-spectively. The water quality index of effluent reached the Ⅲ-class criteria specified in Integrated Wastewater Discharge Standard （ GB 8978-1996）.
