摘　　要：以PTA废水生化出水为对象,分别采用MBR、臭氧氧化、Fenton氧化以及类Fenton氧化等工艺展开深度处理研究,预期出水COD质量浓度小于40 mg/L,色度降至15以下。结果表明,类Fenton氧化法能够将生化出水COD质量浓度降至30~40 mg/L,色度降至10左右,相比于试验中常规的Fenton试剂氧化法,氧化效果更为明显,COD去除率提高了30%左右。In this paper, the effluent from PTA wastewater was treated with MBR, ozone oxidation, Fenton oxidation and Fentonoxidation. The effluent COD was expected to be less than 40 mg/L and the chroma was below 15. The results showed that the Fentonoxidation method could reduce the effluent COD to 30 ~ 40 mg/L and the chroma decreased to about 10. Compared with theconventionalFentonreagent oxidationmethod, the oxidationeffectwasmore obvious andtheCODremoval rate increasedabout 30%.
