This work aimed to perform selective experimental arrays based on the electro-Fenton hybrid (EFH) process for pollutants abatement and toxicity reduction in brewery wastewater (BW). Fenton and electrocoagulation (EC) methods were assessed preliminarily, including the Fe²⁺ catalyst yield and H₂O₂ loss. Each method performance on reducing total organic carbon (TOC) was assessed using a 3³ full factorial design (FFD). Firstly, Fe²⁺ species were produced in short time ranges with the electric current density at 50 A m^-2 and electrical conductivity at 1200 μS cm^-1, followed by EFH experiments with an initial addition of 9.0 g L^-1 H₂O₂. In three levels, initial pH (2.5–3.5) values, Fe²⁺ production-dedicated time (5–15 min), and H₂O₂ renovating percentage (70–90%) were also evaluated, assessing TOC removal. Secondly, nine EFH kinetics, upon the addition of an initial 9.0 g L^-1 H₂O₂ along with H₂O₂ addition at 82.5%, every 5 min, and three levels for pH (3.0–3.4) were carried out, beginning after three Fe²⁺ production-dedicated times (4–6 min). Thirdly, another 60 min kinetic experiment was proposed, with an initial 6 min EC process, followed by a 39 min EFH process, and finally, a 15 min EC process, assessing TOC removal and remaining toxicity. A significant improvement in TOC removal performance, about 90%, along with high toxicity reduction was attained after a refined EFH-based treatment. Therefore, keeping permanent EFH conditions with more suitable parameters provided a unique perspective for removing highly significant pollutants.

这项工作旨在执行基于电子芬顿混合（EFH）工艺的选择性实验阵列，以减少啤酒废水（BW）中的污染物并降低毒性。初步评估了Fenton和电凝（EC）方法，包括Fe ²⁺催化剂的得率和H ₂ O _2的损失。使用3 ³全因子设计（FFD）评估每种方法在减少总有机碳（TOC）方面的性能。首先，在短时间范围内产生Fe ²⁺物种，电流密度为50 A m ^-2，电导率为1200μScm ^-1，然后进行EFH实验，初始添加9.0 g L ^-1 H₂ O ₂。在三个级别中，还评估了初始pH（2.5–3.5）值，Fe ²⁺生产专用时间（5–15分钟）和H ₂ O ₂更新百分比（70–90％），从而评估了TOC去除率。第二，每5分钟添加9份EFH动力学，同时添加最初的9.0 g L ^-1 H ₂ O ₂和82.5％的H ₂ O ₂，并进行三个pH值（3.0-3.4）的测试， 3 Fe ²⁺之后开始生产专用时间（4–6分钟）。第三，提出了另一个60分钟的动力学实验，首先是6分钟的EC过程，然后是39分钟的EFH过程，最后是15分钟的EC过程，以评估TOC的去除和残留毒性。经过精制的基于EFH的处理后，TOC去除性能有了显着改善（约90％），并且毒性大大降低。因此，将永久性EFH条件与更合适的参数保持在一起，为去除高度重要的污染物提供了独特的视角。
