Abstract: Based on the mechanism of micro-electrolysis and the oxidation H2O2,this study has given the proposed of micro-electrolysis and H2O2 oxidation to treatment coating wastewater. The best condition for micro-electrolysis and oxidation can be determined by experiment, too. The experimental results show that this method will enable the value of ρ(CODcr)of the wastewater from 4 000 mg/L to 100 mg/L and the ratio of CODcr removal is up to 95%, and the effluent of wastewater can reach the discharge standards. In addition, this study analyzes the problems of micro-electrolysis, and gives the proposed some solutions to these problem.

Key words: micro-electrolysis, chemical oxidation, coating, paint wastewater
