Treatment of Phenol Wastewater by Three-Phase Three-Dimensional Electrode Reactor

The paper studies the influence of different factors on removal effect of phenol wastewater by three-phase three-dimensional electrode reactor, determines the optimum response conditions, and discusses the reaction mechanism. A self-made reactor is used to process simulation phenol wastewater. The pH value, influent quality concentration of phenol, electrolyte voltage and dosage of Fe^2＋ to the removal effect of phenol are analyzed by experimentation. It had a better removal effect on phenol wastewater by three-phase three-dimensional electrode reactor. The largest removal rate of simulation phenol wastewater with the quality concentration is 300 mg/L could be reached 91.2% under the optimum response conditions of pH = 3, electrolyte voltage = 15 V, the concentration of Fe^2＋ is 1 mmol/L, reaction time is 90 min. The three-phase threedimensional electrode reactor process phenol wastewater economically and effectively. The pH value, electrolyte voltage, dosage of Fe^2＋and influent quality concentration of phenol have a great impact on treatment effect.
