| Abstract: | Internal electrolysis, using iron as the anode material, activated carbon as the cathode material and the catalyst, have been performed to treat copper EDTA complex wastewater. EDTA-Cu＇ s removal efficiency and impact factors with intermittent flow experiment have been investigated in pilot plant; and then, using a continuous flow test to determine the optimum reaction con- ditions： pH = 1.39, retention time is 20 min. Under the best conditions, removal rate of copper and COD are 96. 75% and 27.29% , respectively. Internal electrolysis processes provide adequate ferrous ions to follow-up Fenton reaction and improve the biodegradability of the water. Internal electrolysis process to treat EDTA copper complex wastewater is both efficient and economical, which has great potential at same time. |
