Research Progress of Photocatalysis-Fenton System for Efficient Degradation of Organic Pollutants
With the continuous acceleration of industrialization,more and more pollutants are discharged to cause serious pollution of surface water.The scientific community has confirmed that Advanced Oxidation Techniques(AOPs)are an effective measure to address the problem of severe water pollution.Among the many organic pollutant treatment methods,the light-Fenton method has become an attractive alternative method for removing pollutants from water bodies due to its environmental friendliness,affordable price and wide range of applications.This paper focuses on the main catalytic oxidation of photocatalytic synergistic Fenton in the treatment of printing and dyeing,antibiotics and polyphenolic refractory wastewater in recent years,and compares and analyzes the degradation mechanism of the current photocatalytic Fenton and single photocatalysis and Fenton technology.Then,the strategy of large-scale development and application of optical Fenton technology is proposed,in order to provide new ideas for the future development of optical Fenton catalysis.
