| 摘 要： | 采用Fe为阳极，石墨为阴极，利用TiO2膜光催化电-Fenton法对印染废水进行了降解，讨论了西同作用的机理并考察了溶液pH值对降解率的影响。研究结果表明：光催化电-Fenton法降解率高于电-Fenton法，证明光催化和电一Fenton法在反应过程中具有协同作用。在pH值为3，电流密度为12mA／cm2的反应条件下，可使印染废水的COD去除率达到90．3％，色度去除率98．2％。

| Abstract: | The degradation of dyeing waste water by photocatalysis/electro-fenton employing iron as anode and graph as cathode was discussed in this paper. The mechanism of synergetic effect and effects of pH values on the degradation ratio of dyeing waste water were investigated. Experimental results showed that the degradation ratio of dyeing waste water via photocatalysis/electro-fenton was higher than those via electro-fenton, and it indicates that there was a synergetic effect between photocatalysis and electro-fenton. Given the current density 20 mA/cm2 and pH value at 3.0, the COD removal rate was 90.3% and the decolor rate was 98.2% in the dyeing waste water. |
