Ozonation is one of the most effective and efficient advanced oxidation processes (AOPs) and has shown great potential in the treatment of industrial effluent and wastewater. In the present work, the ozone-Fenton process for % COD and color removal together with electrical energy per order (EE/O) determination for distillery industrial wastewater (DIW) was established. The process was developed by combining the ozone (O₃) with the Fenton (Fe²⁺/H₂O₂) process. The ozone-Fenton (O₃/Fe²⁺/H₂O₂) was compared with other treatment processes such as O₃, Fe²⁺, H₂O₂, O₃/Fe²⁺, O₃/H₂O₂, and Fe²⁺/H₂O₂ for EE/O together with % COD and color removal efficiency for DIW. The removal of color at 100% and chemical oxygen demand (COD) of 96.875% were achieved with a minimum of EE/O of 0.5315 kWh/m³ using the O₃/Fe²⁺/H₂O₂ process by operating at optimum conditions. The % COD and color values obtained using O₃/Fe²⁺/H₂O₂ were significantly higher than those obtained using O₃, Fe²⁺, H₂O₂, O₃/Fe²⁺, O₃/H₂O₂, and Fe²⁺/H₂O₂ processes. The % color, % COD removal, and its associated EE/O were evaluated by varying Fe²⁺, H₂O₂, O₃ inlet and COD concentration, and initial wastewater pH using the O₃/Fe²⁺/H₂O₂ process. The synergy effect of the O₃ and Fe²⁺/H₂O₂ processes was evaluated and reported. Our experimental findings suggest that combining O₃ with the Fe²⁺/H₂O₂ process could effectively treat industrial effluent and wastewater.

使用臭氧辅助 Fenton 工艺处理酿酒厂工业废水：每个订单评估用电能去除颜色和化学需氧量

臭氧化是最有效和最高效的高级氧化工艺（AOPs）之一，在处理工业废水和废水方面显示出巨大的潜力。在目前的工作中，建立了用于测定蒸馏工业废水 (DIW) 的 % COD 和颜色去除以及单次电能 (EE/O) 测定的臭氧-芬顿工艺。该工艺是通过将臭氧 (O ₃ ) 与芬顿 (Fe ²⁺ /H ₂ O ₂ ) 工艺相结合而开发的。臭氧-芬顿（O ₃ /Fe ²⁺ /H ₂ O ₂）与其他处理工艺如O ₃、Fe ²⁺、H ₂ O进行比较₂、O ₃ /Fe ²⁺、O ₃ /H ₂ O ₂和Fe ²⁺ /H ₂ O ₂用于EE/O以及％COD和DIW的颜色去除效率。使用 O ₃ /Fe ²⁺ /H ₂ O ₂工艺，在最佳运行条件下，以 0.5315 kWh/m ³的最低 EE/O 实现了 100% 的颜色去除和 96.875% 的化学需氧量 (COD)条件。使用 O ₃ /Fe ²⁺ /H ₂ O _{2获得的 % COD 和颜色值}显着高于使用O ₃、Fe ²⁺、H ₂ O ₂、O ₃ /Fe ²⁺、O ₃ /H ₂ O ₂和Fe ²⁺ /H ₂ O ₂工艺获得的那些。^{通过改变 Fe 2+}、H ₂ O ₂、O ₃入口和 COD 浓度以及使用 O ₃ /Fe ²⁺ /H ₂ O的初始废水 pH 值来评估 % 颜色、% COD 去除率及其相关的 EE/ O ₂过程。O的协同效应_对3和 Fe ²⁺ /H ₂ O ₂过程进行了评估和报告。我们的实验结果表明，将O ₃与Fe ²⁺ /H ₂ O ₂工艺相结合可以有效地处理工业废水和废水。
