The original process of "coagulating sedimentation-extended aeration-air floatation" has been reformed to "anaerobic-hydrolysis acidification-contact oxidation-coagulating sedimentation" on the basis of the characteristics of dyeing wastewater of nylon textile. With the removal ratios of COD?SS and chromaticity increased 18.9%?10.7%?12.3%, the quality of water outlet is improved greatly, while less sludge and low cost of the whole system are achieved.
Key words： n textile; dyeing wastewater; contact oxidation
