摘　　要：采用电催化氧化法对高浓度含酚废水进行处理,考察了pH值、温度、电压、NaCl的投加量等因素对酚去除率、COD去除率的影响.结果表明,这种方法能有效去除废水中的酚和COD,特别是电压、Na Cl的投加量这两个因素对酚和COD的去除率影响较大.采用了两种复合电催化氧化法处理含酚废水,一种是直接投加H2O2,结果表明酚去除率可达95%以上;另一种是加浓H2SO4,在适宜条件下,酚去除率可达90%以上.由此得出,对含难降解有机物废水的处理,电催化氧化法能达到满意的效果.Treatment of wastewater containing phenol by electrolysis of catalysis oxidation is researched.The effect of temperature pH,added NaCl amount,voltage and so on the removal efficiency of phenol and COD is discussed. The results show that the method can remove phenol and COD of wastewater efficiently. In addition, electrolysis method of complex catalysis is employed to treat wastewater containing phenol. One method is to add H_2O_2 to the solution directly. The other method is to add high concentration H_2SO_4 to the solution. The results show that the removal rates of phenol are over 95% and 90% respectively. So wastewater containing poor_degradable organism can be treated by Electrolysis of Catalysis Oxidation,results are satisfatied.
