Global consumption and discharge of antibiotics have led to the rapid development and spread of bacterial antibiotic resistance. Among treatment strategies, electrochemical advanced oxidation processes (EAOPs) are gaining popularity for treating water/wastewater containing antibiotics due to their high efficiency and easiness of operation. In this review, we summarize various forms of EAOPs that contribute to antibiotic degradation, including common electrochemical oxidation (EO), electrolyte enhanced EO, electro-Fenton (EF) processes, EF-like process, and EAOPs coupling with other processes. Then we assess the performance of various EAOPs in antibiotic degradation and discuss the influence of key factors, including electrode, initial concentration and type of antibiotic, operation conditions, electrolyte, and water quality. We also review mechanisms and degradation pathways of various antibiotics degradation by EAOPs, and address the species and toxicity of intermediates produced during antibiotics treatment. Finally, we highlight challenges and critical research needs to facilitate the application of EAOPs in antibiotic treatment.
全球抗生素的消费和排放导致了细菌抗生素耐药性的迅速发展和传播。在治疗策略中，由于其高效和易于操作，电化学高级氧化工艺（EAOPs）在处理含抗生素的水/废水方面越来越受欢迎。在这篇综述中，我们总结了各种形式的 EAOPs，这些方法有助于抗生素的降解，包括常见的电化学氧化（EO）、电解质增强的 EO、电芬顿（EF）过程、EF 类似过程以及与其他过程耦合的 EAOPs。然后，我们评估了各种 EAOPs 在抗生素降解方面的性能，并讨论了关键因素的影响，包括电极、抗生素的初始浓度和类型、操作条件、电解质和水质。我们还回顾了 EAOPs 降解各种抗生素的机制和降解途径，并讨论了抗生素处理过程中产生的中间产物的种类和毒性。最后，我们强调了在促进 EAOPs 在抗生素处理中的应用方面存在的挑战和关键的研究需求。
