好氧颗粒污泥处理偶氮染料废水研究进展

Research progress of aerobic granular sludge in the treatment of azo dye wastewater

偶氮染料作为纺织印染中使用最多的染料,与其中间产物芳香胺都具有一定的毒性。在众多处理方法中,生物法因其经济环保的特点一直居于应用和研究的首位。而好氧颗粒污泥(AGS)因其抗毒性能力强、生物丰富度高等特点逐渐被应用于染料废水的处理。本文论述了偶氮染料脱色和矿化原理,相关因素对AGS及其处理染料废水效果的影响和国内外部分相关实验。根据国内外研究现状对未来颗粒污泥处理染料废水进行了展望,从而为好氧颗粒污泥的偶氮染料废水处理提供参考和依据。

Azo dye, as the most used dye in textile printing and dyeing, has certain toxicity with its intermediate aromatic amine. Among many treatment methods, biological method has always been the first in application and research because of its economic and environmental characteristics. Aerobic granular sludge(AGS) has been gradually applied to dye wastewater treatment because of its strong anti-toxic performance and high biological richness.The principle of decolorization and mineralization of azo dyes, the influence of related factors on AGS and its treatment of dye wastewater and some related experiments at home and abroad were discussed. According to the research status at home and abroad, the future treatment of dye wastewater with granular sludge was prospected,which provided reference and basis for the treatment of azo dye wastewater with aerobic granular sludge.
