三维电极法处理废水的研究进展

Research Progresses in Treatment of Wastewater Using Three-Dimensional Electrode

传统二维电极面体比小、电流效率低、能耗高等不足而制约了其降解废水的实际应用。三维电极相对于二维电极来说,具有面体比大、离子间距小、传质效果好等优势,因而在降解废水中得到了广泛应用。本文介绍了三维电极的分类、制备方法和载体种类,并对三维电极电催化废水的研究进行了简单的综述。阐述了三维电极在处理废水中的电化学催化机理,同时对三维电极所面临的急需解决的问题和发展趋势作了简要的分析。

The application of traditional two-dimensional electrode in treatment wastewater is limited due to its disadvantages such as low surface/volume ratio,low current efficiency and high energy consumption.In comparison with conventional two-dimensional electrode,the three-dimensional electrode has advantages such as high surface/volume ratio,short distance between electrodes and good transferring effect which make it popular in application.In this paper,the classification,preparation methods and carrier types of three-dimensional electrode are introduced,and researches on electrochemical treatment of wastewater are reviewed.The electrocatalytic mechanism of three-dimensional electrode is introduced and its developing tendency is predicted.
