For optimizing HO generation in three-dimensional electro-Fenton (3D-EF) to enhance efficacy in treating organic wastewater, a comprehensive analysis from various perspectives of HO generation was provided. By quantifying the generation of HO within the reaction system and comparing it with the changing trends in organic wastewater treatment efficiency, a close correlation between HO generation and organic wastewater treatment was revealed. A reliable and accurate kinetic model for HO generation was formulated by building upon the reactions of HO with electrodes and coexisting substances. The mathematical formulation of the kinetic model pinpointed pivotal factors influencing HO generation, including current density, dissolved oxygen concentration, and the Fe catalytic activity substance. The experimental data and fitted results under various conditions indicated that the model could reasonably and accurately describe the relationship between pivotal factors and the quantity of generated HO. Crucial strategies were proposed to enhance HO generation in the 3D-EF system by drawing from the impact rules of pivotal factors on HO generation. These strategies primarily focused on improving electrode performance, optimizing reactor conditions, and refining particle electrode preparation processes.
