| Abstract: | An experiment on advanced treatment of printing and dyeing wastewater was carried out using ABR-contact oxidation-air floatation,and an exploration of engineering design operation parameters was done.The results showed that if hydraulic retention time was 12 h in the ABR,COD volume load in the contact oxidation was 0.6 kg/(m3·d),after the decoloration in air floatation,the COD and color indexes of the wastewater had all reached the first-order of "The Discharge Standard for Water Pollutants of Dyeing and Printing of Textile Industry"(GB 4287—92).The running effect was stable and cost was low. |
