  • Decolorization of Reactive Dyes and Dyeing Wastewater by Microorganisms under Anaerobic Conditions

説明

The decolorizations of four reactive dyes with azo or anthraquinone group, printing wastewater and winch wastewater were investigated using microorganisms under anaerobic conditions. Reactive dyes with azo group were effectively decolorized. The mechanism of decolorization was suggested to be a reductive cleavage of azo bond. Decolorization rate increased in the presence of organic nutrients such as desizing wastewater. Decolorizations of printing and winch wastewaters were easily achieved as good as for azo dyes. For an artificial wastewater made from 70% of the solution of four reactive dyes and 30% of desizing wastewater, 85% decolorization and 65% COD removal were attained using anaerobic-aerobic continuous treatment.
