摘要：
Anaerobic ammonia oxidation (Anammox) boasts a unique nitrogen removal process, appealing to researchers. However, its technological advancements are impeded by environmental sensitivity and slow bacterial growth. Integrating it with other wastewater treatments is crucial for its further development. Microbial fuel cells (MFCs) can convert nitrogen-containing pollutants into harmless substances (N2) while generating electrical currents, and the electrical currents they generate promote the growth and metabolic activities of Anammox bacteria (AnAOB), which allows Anammox to have a higher nitrogen removal efficiency. This paper offers a comprehensive summary of the research progress regarding the coupling process of Anaerobic ammonia oxidation microbial fuel cell (Anammox-MFC), systematically elucidates the structure of the currently commonly used Anammox-MFC, and at the same time provides an in-depth exploration of the operation mechanism in its coupling process. Subsequently, this paper also explores the key factors affecting Anammox-MFC such as pH, temperature, organics, etc., and comprehends that all these factors are crucial for optimizing the system. Finally, this paper presents the challenges of Anammox-MFC including technology optimization, microbial synergy, environmental factors. Meanwhile, it looks forward to the future development of this technology and discusses the improvement strategies to elevate the performance of the system for denitrogenating and electricity production. As a green and sustainable technology, Anammox-MFC has a broad prospect for future research in the field of denitrogenation. Overall, this paper provides the first detailed overview of Anammox-MFC research in recent years, offering valuable insights for the subsequent stage of research.
