摘要
印染废水是普遍的难处理废水之一,而其中偶氮染料废水的总量则占有很大部分。偶氮染料废水具有的普遍特点是生化性差、处理难度大、COD(化学需氧量)高、色度高等。概述了偶氮染料废水电化学处理工艺的发展现状和研究热点,并综合对比了其处理工艺,指出应进一步发掘催化剂的种类、扩大修饰电极的适用范围,提高偶氮染料废水的处理效率。
Printing and dyeing wastewater is one of the universal refractory wastewater, while the amount of azo dye wastewater holds the very major part.The general characteristics of azo dye wastewater are poor biochemical, difficult to process, high COD and high chroma etc..The development status and research focus of chemical treatment technologies of azo dye wastewater were summarized, and the treatment technologies of wastewater were comprehensively compared.It was pointed out that the types of catalyst should be further explored, the application scope of modified electrode should be extended, and the process efficiency of azo dye wastewater should be improved.
