The use of three-dimensional(3D)electrodes in water treatment is competitive because of their high catalytic efficiency,low energy consumption and promising development.The use of particle electrodes is a key research focus in this technology.They are usually in the form of particles that fill the space between the cathode and anode,and the selection of materials used is important.Carbon-based materials are widely used because of their large specific surface area,good adsorption performance,high chemical stability and low cost.The principles of 3D electrode technology are introduced and recent research on its use for degrading organic pollutants using carbon-based particle electrodes is summarized.The classification of particle electrodes is introduced and the challenges for the future development of carbon-based particle electrodes in wastewater treatment are discussed.

三维(3D)电极技术催化效率高、能耗低、发展前景广阔,是一种极具竞争力的水处理技术。在二维电极系统的基础上引入第三电极,就形成了三维电极系统,引入的第三电极又称为粒子电极。三维电极系统中的粒子电极一般呈颗粒或碎屑状,填充在阴极和阳极之间。三维电极系统的核心是粒子电极,因此粒子电极材料的选择是三维电极技术研究的重点。碳基材料具有比表面积大、吸附性能好、化学稳定性高、价格低廉等优点,在三维电极技术中被广泛用作粒子电极。本文综述了近年来碳基材料作为粒子电极降解有机污染物的研究进展,总结了三维电极技术的原理、粒子电极的分类和碳基粒子电极的研究现状,并讨论了电极在污水处理中面临的挑战和未来的发展。
