Research Progress on Advanced Oxidation Method for Treating Printing and Dyeing Wastewater
In recent years,with the rapid development of the printing and dyeing industry,the discharge of printing and dyeing wastewater has been continuously increasing.Printing and dyeing wastewater has the characteristics of complex composition,high chromaticity,high alkalinity,high content of difficult to degrade organic matter,and poor biodegradability,making it one of the difficult to treat industrial wastewater.How to efficiently treat printing and dyeing wastewater is crucial to people's livelihood.Advanced oxidation method has the characteristics of deep degradation,high removal rate,and complete destruction of pollutant structure,and is widely used in the treatment of printing and dyeing wastewater.At present,there are six common advanced oxidation methods,namely electrocatalytic oxidation,wet catalytic oxidation,photocatalytic oxidation,ozone catalytic oxidation,Fenton catalytic oxidation,and Fenton-like catalytic oxidation.This paper reviews common advanced oxidation methods,analyzes their applications in the treatment of printing and dyeing wastewater,and looks forward to their development direction,in order to better utilize advanced oxidation methods to treat printing and dyeing wastewater.
