摘　　要：餐厨垃圾是城市主要的有机固体废弃物。厌氧消化能够在实现餐厨垃圾减量化的同时回收能源,已成为主流处理技术之一。阐述了餐厨垃圾厌氧消化过程中间代谢产物累积所带来的技术风险,重点从微生物角度分析抑制失稳的机理,并进一步介绍了生态优化、生物促进剂添加和微生物驯化等生物强化策略的具体作用,以保证系统高效产气和稳定运行,为餐厨垃圾规模化处理提供参考。As the main organic solid waste component in the urban areas,kitchen waste is produced in large quantities and causes serious pollution.Anaerobic digestion has become one of the mainstream processing technologies,which can reduce the amount of food waste and recover energy simultaneously.This paper discussed the technical risk of metabolite accumulation in the anaerobic digestion of kitchen waste,and the mechanism of inhibitory instability from a microbial perspective was analyzed.Furthermore,bioaugmentation strategies such as microecological regulation,additive supplementation,and microbial domestication are introduced to guarantee efficient biogas production and stable operation,which can provide a reference for large-scale treatment of kitchen waste.
