摘　　要：厌氧消化是一种有机废弃物无害化、资源化处理方式,它能够产生清洁能源沼气。含氮有机废弃物降解过程中容易产生氨氮,当其浓度过高时厌氧消化微生物活性受到抑制、甲烷产量下降,严重时会导致反应体系崩溃,造成严重的经济损失。文章通过查阅大量文献,综述了氨氮对有机废弃物厌氧消化的抑制作用及抑制模型,讨论了氨氮对厌氧微生物的抑制作用机理,并重点探究了应对氨氮抑制的调控策略,旨在为消除厌氧消化体系的氨氮抑制提供理论基础,促进利用厌氧消化技术处理含氮有机废弃物的工业应用。Anaerobic digestion nowadays applied to organic waste degradation produces methane as a clean energy simultaneously. However, anaerobic digestion of N-rich organic waste generates ammonia that, if in high concentration, would inhibit microbial activity, which will result in methane production decline, or even worse - digester failure, causing economic loss. This paper, based on literature reviewing, provided a summary of researches on ammonia inhibition during anaerobic digestion of organic waste as well as the inhibition models; in addition, the impact of ammonia inhibition on microbial population were evaluated, the influencing parameters discussed, and the appropriate control strategies suggested.
