Abstract A three-dimensional-electrode Electro-Fenton Depth coupling method was applied on industrial vinylon waste-water treatment using mosaic electrode made from brass copper. the reaction paths and mechanisms in equipment was preliminarily investigated. They were then compared with those of three-dimensional electrode method, common Electro-Fenton method and common electrolysis method. The results indicated that the removal rate of the volatile phenol COD achieved 93.6% at a electrolysis period of 3.0h, initial pH of 4.0, electrodes space of 3cm, electric current density of 30mA/cm2and brass copper dosage of 10g/L. By such experiment, the research tried to verify that a three-dimensional- electrode Electricity-Fenton Depth coupling method using mosaic electrode made from brass copper ore works more effectively than traditional three-dimensional electrode method, common fenton method and common electrolysis method.
