Abstract

Electricity-driven anaerobic ammonia oxidation (anammox) has garnered extensive attention as a novel, up-and-coming ammonium removal technology because of its broad, cost-efficient, and eco-friendly application. However, the anammox occurring in anode did not receive the attention it deserved. The underlying mechanisms, regulatory strategies, and technical and economic potential of anodic anammox technology are still poorly understood. Thus, we discussed the recent advance in anodic anammox, emphasizing the associated bacteria groups, and assessed the technological and economic potential of the process in terms of operating conditions and energy consumption. It was unravelled that the energy consumption of anodic anammox varies from 0.002 to 0.80 ± 0.09 kWh kg⁻¹ N. This review can improve our understanding of anodic anammox and provide a theoretical foundation for future regulation and practical applications.

微生物电解池阳极厌氧氨氧化的最新进展

电驱动厌氧氨氧化（anammox）作为一种新型、新兴的氨去除技术，因其应用广泛、成本效益高和生态友好而受到广泛关注。然而，发生在阳极中的氨氧化作用却没有得到应有的重视。人们对阳极氨氧化技术的基本机理、监管策略以及技术和经济潜力仍知之甚少。因此，我们讨论了阳极氨氧化技术的最新进展，强调了相关的细菌群，并从操作条件和能源消耗方面评估了该工艺的技术和经济潜力。本综述可增进我们对阳极氧化还原法的了解，并为今后的监管和实际应用提供理论基础。

期刊介绍： The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
