摘　　要：“湿热预处理+厌氧消化”是我国餐厨垃圾处理的主流工艺路线。经湿热预处理后,固形物的C/N下降,导致厌氧消化反应器出现氨氮抑制而不能稳定运行,严重时甚至出现运行失败。因此,寻找并提出有效缓解氨氮抑制的方法和途径,对于餐厨垃圾厌氧消化的正常稳定运行具有重要意义。通过文献调研阐明了餐厨垃圾厌氧消化出现氨氮抑制的微生物机理,总结了缓解氨氮抑制的相关方法,包括提高物料C/N、运行参数优化、氨氮去除和微生物驯化,提出了未来缓解氨氮抑制的研究方向,为餐厨垃圾处理的实际工艺改进提供科学思路。“Hydrothermal pretreatment+anaerobic digestion”is the main processing route for treating food waste in China.After the hydrothermal pretreatment,the C/N ratio of solid residue decreased,resulting in ammonia inhibition appearance in the anaerobic digester and unsteady running condition of the digester,even leading to operation failure in severe cases.Therefore,feasible methods and possible pathways of alleviating ammonia inhibition was of great significance for the normal and stable operation of anaerobic digesters treating food waste.In this paper,the ammonia inhibition mechanism of food waste caused by microorganisms during anaerobic digestion was illustrated by literature review,and the methods for alleviating ammonia inhibition were summarized,including improvement of material C/N ratios,operation parameters optimization,removal of ammonia and acclimation of microorganisms.The research direction of alleviating ammonia inhibition in future was also prospected.It can provide references for processing improvement of food waste treatment in practical engineering.
