【Abstract】 With the electro chemical methods, H 2O 2 is produced on the cathode in the electrolytic cell, then H 2O 2 reacts with Fe 2+ dissolved on the anode to produce Fenton reagent. Fenton reagent is used as an oxidant in the treatment of dye wastewater. Results of COD analysis show that COD removal rate is above 80%. Several factors affecting the energy consumption in the electrolytic cell are analyzed. If the current density of electrolysis is controlled within 10*!mA/cm 2, the electrolysis voltage can be controlled within 5V.更多还原
