| Abstract: | To improve the biodegradability of strong alkaline wastewater, the electrochemical oxidation process was studied for high-concentration phenolic sodium wastewater. The results indicate that the process was able to remove effectively colourity and CODCr . Chlorine residual played an important role in the removal of CODCr and colourity. Under the optimum electrolysis condition(I=714 A/m2; V=10 V; T=30 min), the process consisted of neutralization, electrochemical oxidation, bio-chemical degradation was proved to be applicable. |
