摘　　要：在工业生产活动中排出的难降解废水污染物浓度高、毒性大且可生化性较差,对人体和环境造成了严重危害。三维电极体系是在传统二维电极体系中填充粒子电极使得污染物在粒子电极和电极板表面发生反应,具有降解效率较高、操作简单、绿色环保等优点。文章对三维电极体系中粒子电极的分类、负载改性方法、负载物以及降解机理进行了综述,并对粒子电极的制备、改性优化和应用前景进行了展望。优化粒子电极能提高其电解效率,降低运行成本,可为三维电解法在难降解废水处理中的实际应用提供技术支撑。Refractory wastewater discharged from industrial production activities,which is characterized by high concentration,high toxicity,and poor biodegradability,endangers human health and destroys the ecological environment.The three-dimensional(3D)electrode system is filled with particle electrodes in a traditional two-dimensional(2D)electrode system,so that pollutants can react on the surface of particle electrodes and electrode plates.It has the advantages of high degradation efficiency,simple operation and environmental protection.This paper studies the classification of particle electrodes,loading modification methods,loading materials and degradation mechanism in three-dimensional electrode system,and the preparation,performance improvement,and application prospects of particle electrodes in the 3D electrode system are also discussed.The optimization of the particle electrode can improve electrolysis efficiency and reduce operating cost,which provides technical support for the practical application of the 3D electrolysis method in the treatment of refractory wastewater.
