摘　　要：在污水深度处理领域,电芬顿法作为均相芬顿体系的衍生,已经广泛应用于高浓度难降解有机废水的处理中。铁离子作为均相电芬顿体系中的主要活性物种,由于其在反应过程中易于沉淀的特点,从而会产生大量的铁污泥,降低了均相电芬顿处理废水的效率。因此,采用将铁活性物种负载到载体材料制成非均相电芬顿体系主催化单元的方法,可有效减少铁离子的流失,同时也能提高反应效率。本文概述了非均相电芬顿的反应机理,通过介绍非均相电芬顿电极材料和催化剂两个方面来说明非均相电芬顿的发展现状,并对其未来的发展状况进行了展望。In sewage depth processing,electro-Fenton,as a derivative of homogeneous Fenton technique,has been widely used in the treatment of heavily contaminated wastewater. As the main active species of iron ions in the homogeneous electric-Fenton system,there is a large amount of iron sludge in the process of the reaction,which can reduce the efficiency of homogeneous electro Fenton process. The method of supporting the iron active species on the carrier materials to prepare the main catalytic unit of the heterogeneous electro-Fenton can effectively reduce the loss of iron ions and improve the efficiency of the electro-reaction.In this paper,we summarizedthe reaction mechanism of heterogeneous electro-Fenton,the development of heterogeneous electro-Fenton by introducing two aspects of heterogeneous electro-Fenton electrode materials and its future development.
