  Abstract

In this paper, we investigated the effect of an indirect oxidation zone in an electrolysis reactor that used Ti/lrO2 as the anode and SUS 316L as the cathode. Based on our preliminary results, the electrolysis reactor was operated with pole plate interval of6 mm, current density 1.0 A/dm2L and electrolyte concentration 15%. The removal efficiency, COD (chemical oxygen demand), was additionally increased by 55% and 12.5~15.0% in the direct and indirect oxidation zones, respectively. The removal efficiencies of T-N (total nitrogen) and T-P (total phosphorus) were found to be 88% and 75%, respectively. It was shown that the additional effect of the indirect oxidation zone on the removal was nearly negligible, Also, as the removal of COD, T-N and T-P took place during the initial 2~5 days ofreaction, it was concluded that there was no need to extend the retention time of the electrolysis reactor.
