【Abstract】 Feasibility and effect of electrochemical oxidation treatment method were studied dealing with high concentrated phenolic sodium wastewater. The results indicate that colourity and CODcr removal rates of the wastewater can reach 74.5% and 60 8% respectively under the optimum electrolysis condition ( I =714?A/m 2; V =10?V). Remanent chlorine plays an important role on the removal of CODcr and colourity of the effluents. In addition, the electrochemical oxidation can improved the biodegradability of the wastewater. The technique of treating phenolic sodium wastewater by neutralization—electrochemical oxidation—biological purification process proved to be applicable.更多还原
