采用优化两级A/O+高级氧化组合工艺处理印染综合废水。结果表明，通过两级A/O生化处理工艺后，尾水NH3-N、TN、TP、BOD5分别为2.34、9.75、0.67、13.1 mg/L，尾水采用Fenton或臭氧氧化后出水COD、色度分别低于60 mg/L及30倍，达到《城镇污水处理厂污染物排放标准》一级B标准。 Fenton氧化的反应条件为：pH 4~5，双氧水、硫酸亚铁、PAM的投加质量浓度分别为600、120、2 mg/L，吨水药剂处理成本为1.22元，低于臭氧氧化的成本。

The combined process,optimized two-stage A/O+advanced oxidation,has been used for treating integrat-ed printing and dyeing wastewater. The results show that after being treated by the two-stage A/O biochemical treat-ment process,NH3-N,TN,TP,BOD5 of the tail water are 2.34,9.75,0.67,13.1 mg/L respectively. After the tail wa-ter is treated by Fenton or ozone oxidation process,the effluent COD,and chroma are lower than 60 mg/L and 30 times,respectively. It is met than the First-B of the Discharge Standard of Pollutants in Urban Sewage Treatment Plants. The reaction conditions of Fenton oxidation are as follows:pH is 4-5,hydrogen peroxide 600 mg/L,ferrous sulfate 120 mg/L,and PAM 2 mg/L. The cost of chemicals treatment per ton of water is ￥1.22,lower than the cost of the ozone oxidation method.
