Abstract
In Cu-EDTA wastewater treatment,due to the complex structure and stable nature of metal-organic complexes,it is necessary to re-ly on advanced oxidation technology to break complexes and degrade them in order to achieve green and efficient treatment effects. This work listed six common advanced oxidative complex-breaking treatment technologies,namely,electrocatalysis,photocatalysis,ozone,Fenton,acti-vated persulfate and discharge plasma,and the advantages and shortcomings of different technologies were compared and analyzed. Meanwhile,the advanced oxidation complex-breaking co-processing technologies in recent years were introduced. Their optimization,enhancement and technological applications were summarized. Besides,the exploration direction of advanced oxidation technology in the research of Cu-EDTA decomplexation was outlooked,and the importance of degradation mechanism research,joint technology development and practical engineering application was emphasized,which could provide a reference for advanced oxidative decomplexation treatments of Cu-EDTA wastewater.
