干式厌氧发酵技术是一项有机废弃物处理与资源化利用技术,在处理有机废弃物的同时既可产生清洁的甲烷能源,又可实现区域环境的改善,但其反应过程中极易出现酸化和氨氮抑制现象,进而导致反应体系产气效率降低甚至崩溃.综述了干式厌氧发酵体系失稳调控机制,总结了酸化和氨氮抑制两类失稳情况的调控策略,分析了外源添加导电材料(生物炭、磁铁矿等)、添加微量元素(铁、镍等)和生物强化以及各项调控策略之间的混合协同调控.以期为缓解干式厌氧发酵过程中出现的酸化和高氨氮抑制现象,从而实现高效稳定运行提供相应的理论参考.
Research Progress on the Regulation Mechanism and Strategy of Dry Anaerobic Digestion Based on Unstable State
Dry anaerobic digestion is a technology for organic waste treatment and resource utilization,while treating organ-ic waste,the clean methane energy can be generated and regional environmental can be improved.However,acidification and ammonia nitrogen inhibition are very easy to occur in the reaction process,which leads to low gas production efficiency or even collapse of the reaction system.In this paper,the mechanism of instability control in dry anaerobic digestion system were reviewed,and the control strategies for acidification and ammonia nitrogen inhibition were summarized.The exogenous addition of conductive materials(biochar,magnetite,etc.),addition of trace elements(iron,nickel,etc.),bio,as well as the mixed cooperative regulation among various measures were analyzed.It is expected to provide a theoretical reference for alleviating acidification and inhibition of high ammonia nitrogen in the process of dry anaerobic digestion so as to achieve efficiently and stably operation.
