Continuous Electrochemical Oxidation of Phenol Using a Three-Dimensional Electrode Reactor
The removal of phenol wastewater was experimentally investigated using a three-dimensional electrode reactor with granular activated carbon and titanium filter electrode arrays. The effects of the electric current, the residence time and the initial concentration on the phenol removal were evaluated. For the initial concentration of 490 mg/L, the phenol removal was obtained as 90% under the conditions of electric current 2 A, residence time 40 min. The effluent path of the electrochemical cell was optimized, using the anode effluent instead of the top effluent, where the phenol and COD removal was both increased to 95% and the corresponding energy consumption was decreased from 9.66 to 7.63 kWh/kg COD.
