Abstract
Electrochemical oxidation is an effective technology for the phenol wastewater treatment, and the anode properties are important to the electrochemical oxidationefficiency. The over-potentials of oxygen evolution have been measured for thestainless steel, feasible graphite and SnO_2/Ti anode respectively. Moreover, the synthetic phenol wastewater was treated by the electrochemical oxidation with the stainless steel or feasible graphite anodes. The experimental results showed that the order of the over-potential is SnO_2/Ti > graphite > stainless steel; meanwhile, the COD values of purified water were approaching to or less than 100 mg·L~(-1), and the phenol concentrations in the purified water were below 0.5 mg·L~(-1).
