| Abstract: | A study on electrocatalytic oxidation of Reactive Red Violet X-2R by bipolar three-phase three-dimensional electrode was carried out.The effects of affecting factors on treatment efficiency,such as voltage,electrodes space,electric current density,initial pH,aeration intensity and so on,were examined.The determined optimum process conditions were as follows： voltage 30 V,electric current density 28 mA/cm2,electrodes space 5 cm,initial pH 6,aeration intensity 3 L/min.The removal rates of the effluent colority and COD were respectively 99.1% and 93.5%,when the dyeing wastewater with initial pH value of 6 was treated for 50 min. |
