摘　　要：难降解有机废水成分复杂、危害大,易导致癌变、畸变,对人类健康产生重大影响,是需要优先治理的环境问题。在许多情况下,采用传统生物法和物理化学法来处理难生化处理有机废水很难达到理想的处理效果,并且其操作工艺复杂,成本相对较高。三维电催化氧化技术的出现为难降解有机废水的处理提供了一种绿色环保高效的方法。三维电催化氧化体系具有传质传热快、脱除效率高、操作简便、占地面积小等优点,呈现广阔的应用前景。结合相关应用研究文献介绍了三维电极的发展历程、基本特性,相应电解装置的特征,并重点阐述了三维电催化氧化体系对难处理有机废水的降解。分析了目前三维电催化氧化处理难降解有机废水存在的问题,并对其发展趋势及有待深入研究的方向进行了展望。以根据实际需求研发新型颗粒电极和催化剂,优化反应器内部的流场及电场,实现反应过程的进一步强化,提高电解效率并降低能耗,为今后的研究与实际应用提供了新的思路。Bio-refractory organic wastewater,which easily causes cancer and mutation,is a serious environmental problem that needs urgent treatment.According to previous experimental results,achieving the desired degradation of the bio-refractory organic wastewater by using traditional biological or physicochemical methods is difficult.In addition,these methods have complex operating processes and high cost.Three-dimensional electrodes used for the treatment of bio-refractory organic wastewater is a new type of environment-protective and efficient electrochemical treatment method.Three-dimensional electrodes have been attracting extensive attention because of their unique properties and advantages,such as high mass transfer rate,high removal efficiency,easy operation,and small footprint.Combined with related application research literature,the development history,the basic characteristics,the corresponding electrolysis device,and the degradation of bio-refractory organic wastewater in the three-dimensional system are introduced.The existing problems of the three-dimensional electrocatalytic oxidation for the treatment of bio-refractory organic wastewater are analyzed,and an expectation for its future development is explained.By developing new particle electrodes and catalysts,the optimization of the flow and electric field inside the reactor to improve the efficiency and strengthen the reaction process further is useful for future research and practical applications.
