Abstract In this paper, a new electric-heterogeneous ozone-catalyzed (E-catazone) process was used in advanced treatment of the secondary biochemical effluent from coking wastewater, and the process's feasibility was also studied. By comparing the E-catazone process with three other processes:the O₃/TiO₂ nanoflowers (TiO_2-NF) process, the O₃/TiO_2-NF/H₂O₂ process, and the electrochemical oxidation process (EO), the technological advantages and oxidation mechanism of E-catazone were investigated. Under the same conditions (O₃ concentration of 84mg/L), the removal rates of COD and TOC (67.9%, 50.0%) in E-catazone process were significantly superior to the performance (25.8%, 20.9%) in O₃/TiO_2-NF process. Even with 5g/L of H₂O₂ added in the above O₃/TiO_2-NF system to promote homogeneous ozone catalytic ability, the obtained removal rates of COD and TOC had only increased to 63.6% and 43.6%, respectively. The performance of O₃/TiO_2-NF/H₂O₂ system was still not as good as the E-catazone process.
