摘要

The effect of the contaminated water feed mode on advanced oxidation performance, for a combined system, using ozonation with electrolysis (ozone-electrolysis) in a two-compartment electrolytic flow cell, was discussed for ozone injection to the cathodic compartment of the cell. When ozone-electrolysis was applied, removal of the chemical oxygen demand (COD) proceeded in the cathodic compartment. The overall COD removal rate increased with the increase in current density for direct feed of contaminated water to the anodic compartment (DFA mode). However, the overall COD removal rate decreased at high current density for direct feed to the cathodic compartment (DFC mode), although the overall performance for the DFC mode was better than the DFA mode. The difference in the dependency of the performance on current density was determined to be due to the difference in the advanced oxidation mechanisms for each mode.
