Research on Electrochemical Oxidation Process for Treating Phenol Cyanide Wastewater
To address the issue of treating phenol cyanide wastewater from coke oven gas,the process was optimized using Fenton reaction,flocculation precipitation,and advanced plasma oxidation technology for pretreatment,followed by electrochemical catalytic oxidation for deep treatment to achieve the goal of treating industrial phenol cyanide wastewater.Through practical application,the results show that selecting the optimal electrochemical catalytic oxidation time of 2.0 hours can effectively treat high concentration pollutants and make the liquid meet national emission standards.
