Fluidized Bed Fenton (FBF) technology, a fusion of the Fenton method and fluidized bed reactor, has emerged as a superior alternative to conventional Fenton technology for treating organic industrial wastewater. This innovative approach has garnered significant attention from researchers in recent years. While earlier studies primarily focused on pollutant degradation in simulated wastewater and catalyst development, there has been a growing interest in examining the alterations in mass or heat transfer performance attributed to fluidized beds. This paper explores the factors that contribute to the effectiveness of Fluidized Bed Fenton technology in efficiently degrading various challenging organic pollutants, while also reducing iron sludge production and expanding the applicable pH range, through an analysis of reaction kinetics. Meanwhile, combined with the related work of fluid dynamics, the research related to mass and heat transfer inside the reactor of Fluidized Bed Fenton technology is summarized, and it is proposed that the use of computers to establish a suitable model of Fluidized Bed Fenton and solve it with the assistance of computational fluid dynamics (CFD) and other software will help to further explore the process of mass and heat transfer inside the fluidized bed, which will provide the basis for the future of the Fluidized Bed Fenton from the laboratory to the actual industrial application.
流化床 Fenton（FBF）技术是 Fenton 法和流化床反应器的融合，已成为处理有机工业废水的传统 Fenton 技术的优越替代品。这种创新方法近年来引起了研究人员的极大关注。虽然早期的研究主要集中在模拟废水中的污染物降解和催化剂开发上，但人们越来越关注流化床引起的传质或传热性能的变化。本文通过反应动力学分析，探讨了流化床 Fenton 技术在有效降解各种难处理有机污染物的同时，减少铁污泥产生和扩大适用 pH 范围的因素。同时，结合流体动力学的相关工作，总结了流化床 Fenton 技术反应器内传质和传热的相关研究，并提出利用计算机建立流化床 Fenton 的合适模型，并借助计算流体动力学（CFD）和其他软件进行求解，将有助于进一步探索流化床内的传质和传热过程，为流化床 Fenton 从实验室到实际工业应用的未来提供基础。
