阳离子染料废水处理技术研究进展

Research progress on treatment technology of cationic dye wastewater

阳离子染料于1855年问世,发展至今应用广泛,但阳离子染料废水排放过程中,会对环境及人体造成危害,因此处理阳离子染料废水逐渐受到各界关注。总结了处理阳离子染料废水的几种方法,包括物理法、化学法和生物法,对3种处理方法对比,表明生物法处理阳离子染料废水是一种绿色、高效、环保的方法,阐述了生物法处理阳离子染料废水的主要类型、研究现状和脱色机理,在此基础上,对当前处理阳离子染料废水的发展趋势进行了展望。

Cationic dye came out in 1855,they have been widely used today.However,in the process of cationic dye wastewater discharge,it will cause harm to the environment and human body and the treatment of cationic dye wastewater has been gradually concerned by all walks of life.This paper reviewed several wastewater treatment methods for cationic dye wastewater,including physical,chemical and biological methods.Through the comparison of above three treatment methods,it is pointed out that the biological treatment of cationic dye wastewater is a green,efficient and environment-friendly method.The main methods,research status and decolorization mechanism of cationic dye wastewater treatment by biological method were emphatically expounded.On this basis,the development trend of cationic dye wastewater treatment was prospected.
