厌氧消化（AD）和热解是世界范围内用于废弃生物质处理的两种有前途的技术。对AD强化技术的兴趣一直在增加，以获得足够的和可持续的甲烷生产与稳定的消化器性能。例如，相当多的注意力已经投入到AD与生物炭的偶联，生物炭是由生物质热化学转化产生的。本文综述了近年来利用生物炭提高反硝化效率的研究进展。综述了生物质炭在促进和平衡水解、产酸-产乙酸、产甲烷以及缓解抑制剂胁迫等方面的重要作用。生物炭主要通过提供发酵菌和产甲烷菌之间的生物电连接、微生物菌落的支持和缓冲能力的增强来促进生物甲烷过程。本文通过对生物质炭的早期应用进行综述，旨在明确生物质炭提高反渗透性能的潜在机制和未来的探索方向。
Anaerobic digestion (AD) and pyrolysis are two promising technologies used worldwide for waste biomass treatment. Interests on intensification techniques of AD has been increasing to obtain sufficient and sustainable methane production with stable digester performance. For instance, considerable attention has been devoted to the coupling of AD with biochar, which is produced by biomass thermochemical conversion. This manuscript presents a comprehensive review about recent achievements in enhancing AD efficiency with the utilization of biochar. The key roles of biochar include enhancing and equilibrating hydrolysis, acidogenesis-acetogenesis, and methanogenesis, as well as alleviating inhibitor stress were summarized. Biochar can promote biomethane process mainly by serving as a provision for bioelectrical connections between fermentative bacteria and methanogens, a support for microbial colonies, and a reinforcer for buffer capacity. Through an overview of the early applications, this paper aims to pinpoint the potential mechanism and future explorative directions of biochar enhancing AD performance.
