在全球气候变化的压力下,生物能源的发展受到越来越多的关注,而沼气发酵作为一种较成熟的生物质能转化方式,得到了极大的重视和快速的发展.如何提高沼气发酵的效率,使其规模化、产业化成为迫在眉睫的问题.混合厌氧发酵作为一种简单、低成本、高效率的提升厌氧发酵的模式,引起了许多学者的关注.本文通过对国内外混合厌氧发酵研究的分析,归纳了各类发酵底物特征,主要阐述了动物粪便、污水污泥及工业废弃物等混合厌氧发酵的研究进展,总结了混合发酵的优势以及影响因素,并展望了混合厌氧发酵研究趋势及应用前景,旨在为混合厌氧发酵的推广及其应用提供理论指导.
Under the pressure of global climate change, the development of bio-energy is receiving more and more attention, and biogas fermentation has gained great attention and rapid development as a more mature biomass energy conversion method. Efficiency, making it scale, industrialization has become an urgent issue.Mixed anaerobic fermentation as a simple, low-cost, high-efficiency anaerobic fermentation mode has aroused the concern of many scholars.Through the domestic and foreign mixed Anaerobic fermentation research, summarized the characteristics of various types of fermentation substrate, mainly elaborated the research progress of mixed anaerobic fermentation such as animal manure, sewage sludge and industrial waste, summarized the advantages and influencing factors of mixed fermentation and prospects The research trend and application prospect of mixed anaerobic fermentation aims to provide theoretical guidance for the promotion and application of mixed anaerobic fermentation.
