PTA废水生化出水深度处理研究

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 Fenton oxidation.The effluent COD was expected to be less than 40 mg/L and the chroma was below 15.The results showed that the Fenton oxidation method could reduce the effluent COD to 30~ 40 mg/L and the chroma decreased to about 10.Compared with the conventional Fenton reagent oxidation method,the oxidation effect was more obvious and the COD removal rate increased about 30 %.
