研究了电解还原含酚废水中的氧生成过氧化氢氧化降解含酚废水的新工艺。考察了pH值、阴极电位、亚铁离子浓度、苯酚浓度等操作条件对苯酚降解率的影响。苯酚连续降解为二氧化碳，在pH值为3时，效率更高，而不是其他pH值。在pH = 3时，苯酚的COD电流效率高于阳极氧化，在初始COD为260-2600 ppm范围内，完全降解的电流效率大于60%。
A novel process of an oxidative degradation of aqueous phenol effluent with hydrogen peroxide produced by electroreduction of oxygen dissolved in the effluent was studied. Effects of operational conditions such as pH, cathode potential, ferrous ion concentration and phenol concentration on the degradation rate of phenol were clarified. Phenol was successively degraded to carbon dioxide at pH 3 with higher efficiency rather than the other pH's. The COD current efficiency at pH 3 was higher than that for the anodic oxidation process of phenol and was more than 60% for complete degradation in the range of 260-2600 ppm of initial COD.
