利用不同废弃物生产沼气，由于其结构复杂、可生物降解性慢等原因，仍存在一定的局限性。为了提高甲烷产率和厌氧消化性能，人们提出了各种基质前处理方法。本文综述了提高厌氧消化效率的预处理技术的最新动向、进展和研究成果。前处理技术主要分为物理、化学、生物和组合四大类。讨论了前处理过程中缓蚀剂形成的影响。揭示了这些前处理技术的能源性能、经济性和环境影响。本研究总结了未来的发展趋势，强调了前处理方法的必要性。
Biogas production from different waste resources still has limitations due to its complex structure and slowly biodegradable nature. To improve methane yield and anaerobic digestion performance, various substrate pretreatment methods have been suggested. This paper reviews the latest trends, progress, and research achievements about pretreatment technologies to improve anaerobic digestion efficiency. The pretreatment techniques are divided into four main groups which are physical, chemical, biological, and combined. The effect of inhibitor formation during the pretreatment process is discussed. The energy performance, economics, and environmental impact of these pretreatment technologies are revealed. This study concludes with future trends and emphasizes the necessity of pretreatment methods.
