摘要
生物难降解有机废水是水处理中的难题之一。电催化氧化技术作为目前处理有机废水方面比较成熟的工艺,其阳极材料是该过程的核心。综述了几种目前应用的电催化氧化阳极材料,并通过对金属氧化物阳极析氧机理的研究得出影响阳极析氧电位的因素。最后,对今后电催化阳极材料的研究方向做了展望,以期获得更好的有机废水处理效果。
Bio-degradable organic wastewater treatment is one of the problems in water treatment.Electro-catalytic oxidation technology is a mature technology in organic wastewater treatment.Anode material is the heart of electrocatalytic oxidation process.Several currently used anodic oxidation materials were presented,and through the study on the mechanism of metal oxide anode for anodic oxygen evolution,factors which would impact oxygen evolution potential were reviewed in this paper.Finally,future research directions of electro-catalytic anode materials were put forward in order to get a better effect for organic wastewater treatment.
