| Abstract: | Printing and dyeing wastewater was treated by hydrolytic acidification- biological contact oxidation -air floatation-biological active carbon process. The treatment process, main constructions and equipment were introduced. The operation results showed that the process can effectively remove BOD5, CODcr, chroma and SS from wastewater. When the influent BOD5, CODcr, chroma and SS were 70-300 mg/L, 2004600 mg/L, 200-600 times and 300-600 mg/L respectively, the effluent quality can reach the I-class discharge standards of water pollutants for dyeing and finishing of textile industry （GB4287-1992）, with BOD5 6-23 rag/L, CODcr 20-30 mg/L, chroma 15 -40 times and SS 25 -70 mg/L. |
