摘　　要：采用水解酸化-MBR-臭氧工艺处理印染废水,结果表明,该工艺组合能有效去除印染废水中的COD和色度等各项指标,当实际进水COD为1170.57mg/L,色度为200倍时,出水COD降至为34.95mg/L,色度为8倍以下,对COD、氨氮、总氮、总磷、色度总去除率分别为97.0%、92.8%、84.28%、92.9%、94%,出水水质优于《纺织染整工业水污染物排放标准》(GB 4287-2012),运行成本为2.33元/m^(3)。Hydrolysis acidification-MBR-O_(3) combined progress was used to treat the dyeing sewage.The results show that the process can remove COD color effectively in the dyeing sewage.When the sewage COD 1170.57 mg/L,the chroma of 200,after treatment,COD was 34.95 mg/L,the chroma was 8 below.The practical results indicate that the total removing rates of COD,NH_(3)-N,TN,TP and chroma were 97.0%,92.8%,84.28%,92.9%and 94%,respectively.Which achieved the higher requirement between Discharge standards of water pollutants for dyeing and finishing of textile industry(GB 4287-2012),operation cost 2.33 yuan/m^(3).
