Abstract The ozone fluidized bed reactor is a multiphase reactor with a series of advantages such as simple structure, low manufacturing cost, easy maintenance and operation, and low energy consumption. In order to find the parameters that can make the ozone fluidized bed better play its advantages in water treatment, a research model of the gas flow circulating reactor based on physical model experiments and computational fluid dynamics methods was built, and the experimental data were compared with the numerical simulation results. Results indicated that the numerical simulation gave a good indication of the fluid flow characteristics inside the ozone fluidized bed. Subsequently, based on numerical simulation, the internal flow field of the ozone fluidized bed was analyzed, and the effects of parameters such as height to diameter ratio, bottom inclined plate angle, and ozone input velocity were further studied. The study found that at a height to diameter ratio of 3, a bottom inclined plate angle of 45 degrees, and an ozone input velocity of 0.05 m/s, the ozone fluidized bed model can best demonstrate its excellent water treatment capacity and high economic efficiency, making sewage treatment technology more efficient and environmentally friendly.Therefore, this method could accurately find the parameters that enabled the ozone fluidized bed reactor to exert its better treatment capacity by creating a model and performing numerical simulation analysis.
