Abstract: Rapid population growth and technological advancements in various industries have led to the generation of significant volumes of wastewater requiring effective treatment. Among the available methods, advanced oxidation processes (AOPs) are highly favored due to their high efficiency, cost-effectiveness, and eco-friendly nature. These processes utilize non-selective hydroxyl radicals (•OH) to oxidize and degrade toxic pollutants in wastewater. Among the AOPs, the Fenton process has demonstrated exceptional efficacy in treating recalcitrant organic compounds. However, a key limitation of this process is the generation of large quantities of sludge, necessitating additional treatment and disposal. The fluidized-bed Fenton (FBF) process addresses this issue by crystallizing iron onto the surface of carriers within the reactor, significantly reducing sludge production.
This presentation provides a comprehensive overview of recent advancements in applying the FBF process to treat industrial wastewater. Case studies are explored across sectors such as thin-film transistor liquid crystal display manufacturing, pharmaceuticals, textiles, phenol production, refractory organics, petrochemicals, and other chemical industries. These examples underscore the potential of FBF technology to effectively reduce recalcitrant organic contaminants in wastewater. Key advantages of the FBF process over conventional Fenton-based technologies are highlighted, including improved performance, optimized operating conditions, and critical factors influencing removal efficiency. Additionally, the presentation delves into the reaction kinetics and mechanisms involved, along with the characteristics and selection of carrier materials used in the process. Finally, insights into large-scale applications of the FBF process are discussed, showcasing its viability and adaptability in addressing the challenges of industrial wastewater treatment on a broader scale.
