This review aims to provide a comprehensive understanding of the potential of CMs-dominated DIET in the degradation of recalcitrant organic pollutants in AD. The review covers the mechanisms and efficiencies of recalcitrant organic pollutant degradation by CMs-dominated DIET, the comparison of degradation pathways between DIET and chemical treatment, recent insights on DIET-enhanced degradation, and the evaluation of the potential and future development of CMs-dominated DIET. The review emphasizes the importance of coupled syntrophic microorganisms, electron flux, and physicochemical properties of CMs in enhancing the degradation performance of AD. Additionally, it highlights the advantages of DIET-led syntrophic metabolism over traditional oxidation technologies in terms of environmental friendliness and efficiency. Finally, the review acknowledges the potential risks associated with introducing CMs into AD systems and provides guidance for waste treatment and energy recovery.
本综述旨在全面了解以共代谢物为主导的直接电子传递（DIET）在厌氧消化（AD）中降解难降解有机污染物的潜力。综述涵盖了共代谢物为主导的 DIET 降解难降解有机污染物的机制和效率、DIET 与化学处理之间降解途径的比较、DIET 增强降解的最新见解，以及对以共代谢物为主导的 DIET 的潜力和未来发展的评估。本综述强调了耦合共代谢微生物、电子通量和共代谢物物理化学性质在增强 AD 降解性能方面的重要性。此外，它还强调了 DIET 主导的共代谢代谢相对于传统氧化技术在环境友好性和效率方面的优势。最后，本综述承认了将共代谢物引入 AD 系统所带来的潜在风险，并为废物处理和能源回收提供了指导。
