细菌染料脱色机理研究进展

摘要

Treatments against the textile printing and dyeing wastewater, one kind of hard-degradation industrial wastewater, have been given priority to the biological treatment combining with the physical and chemical treatment. In the biological treatment, the use of bacteria for dye decolorization is one of the emphasis which removes colors by adsorption or degradation dyes. By summarizing the decolorizing bacteria for azo dyes, anthraquinone dyes and triphenylmethane dyes, and their decoloring enzyme and dye degradation product, the possible decolorizing mechanism for three dyes by using bacteria was discussed.%纺织印染废水属于难处理工业废水，对其处理一直以生物处理为主、物理化学处理为辅。在进行生物处理时，利用细菌对其中的染料进行脱色是其中的重点。细菌对染料的脱色包括吸附脱色和降解脱色。本文通过总结对偶氮染料、蒽醌染料和三苯甲烷染料三种应用最广泛的染料具有脱色作用的细菌及其染料脱色的相关酶、降解产物，探讨了细菌对这三种染料可能的脱色机理。
