Recent advancements in bio-electrochemical systems (BESs) for antibiotic removal are receiving great attentions due to the electro-active bacteria on the electrode that could elevate the removal efficiency. Enhanced detoxification performance of BESs compared to the traditional biological processes indicates the great potential serving as a sustainable alternative or a pre-/post-processing unit to improve the performance of biological processes. However, the successfully application of BESs to antibiotic-polluted water remediation requires a deeper discussion on their operational performance and emerging coupled systems. In order to address BESs as a practical option for antibiotic removal, we deeply analyze the detoxification mechanism of antibiotic treatment by BESs, involving BES fundamentals, extracellular electron transfer and degradation pathways via functional enzymes of microorganisms, followed by systematic evaluations of the operational conditions. Furthermore, the recently-emerged BESs combined with other techniques for practical applications has been summarized and emphasized. This review further directions the current limitations such as the potential risk of antibiotic resistance genes, etc., and prospects for the attenuation of antibiotics via BESs related techniques, promoting the development of practical application.
用于抗生素去除的生物电化学系统（BESs）的最新进展受到了极大关注，这是因为电极上的电活性细菌能够提高去除效率。与传统生物过程相比，BESs增强的解毒性能表明其作为一种可持续替代方案或预处理/后处理单元以改善生物过程性能具有巨大潜力。然而，BESs在抗生素污染水修复中的成功应用需要对其运行性能和新兴耦合系统进行更深入的讨论。为了将BESs作为抗生素去除的实际选择，我们深入分析了BESs对抗生素处理的解毒机制，包括BESs的基本原理、细胞外电子转移以及微生物功能酶的降解途径，随后对运行条件进行了系统评估。此外，还总结并强调了最近出现的BESs与其他技术相结合的实际应用情况。本综述进一步指出了当前的局限性，如抗生素抗性基因的潜在风险等，以及通过BESs相关技术对抗生素进行衰减的前景，推动了实际应用的发展。
