Research Progress in Degradation of Pharmaceutical Wastewater by Electro-Fenton Coupling process
The electro-Fenton process can degrade organic pollutants in pharmaceutical wastewater through the reaction of Fe2+and H2O2 to generate hydroxyl radicals(·OH)with high activity and strong oxidation capacity.In this paper,the principles and the research progress in recent years of three-dimensional electrode coupled electro-Fenton technology,ozone coupled electro-Fenton technology,optical coupled electro-Fenton technology,ultrasonic coupled electro-Fenton technology,and microbial coupled electro-Fenton technology were introduced,the oxidation effects of various coupling processes were discussed,and finally the shortcomings and development directions of electro-Fenton coupling process were prospected.
