摘要
微生物法是染料废水治理的重要方法。本文综述了特异性酶作用下好氧细菌和真菌对偶氮染料的脱色以及厌氧条件下氧化还原介质作为电子穿梭体时偶氮染料的非特异性还原过程。指出厌氧偶氮还原是偶氮染料还原的主要形式,电子供体不同脱色效率不同。对目前生物法去除偶氮染料存在的问题进行了分析,提出了相应的对策措施。
Biological process is an important approach to treat the dye wastewater. The azo dyes decolouration by special azoreductase of different aerobic bacteria and fungi was summarized. Under anaerobic condition, reductive decolourization of azo dyes was carried in the presence of redox mediators which act as electron shuttle. It was also pointed out that azo dye reduction occurred mainly under anaerobic condition. Different electron donor resulted in different decolourization rate. Problems of current biotechnology were analyzed and corresponding measures were discussed.
