After the coagulation and sedimentation in the jar test with ferric chloride, the residual COD in the supernatant was 9000 mg/L which was further oxidized by chloric acid or with Fenton method. The COD removal efficient increased with the increasing of the dosage of chloric acid from 0.5 ~ 100 g/L or the H2O2/Fe2+ from 5/2.5 ~ 50/25 g/L, and the economical dosage were suggested as chloric acid 50 g/L or the H2O2/Fe2+ 50/25 g/L which resulted in the residual COD of 400 and 3300 mg/L individually for 95 and 63 % COD removal percentages. Oxidation test showed that only 5 minutes was needed for 92 % COD removal in the case of chloric acid dosage 50 g/L.
