互花米草是国家环保总局首批公布的十大外来生物入侵物种之一,也是唯一的海岸盐沼植物。由于生长速度快、繁殖能力强、生物量大以及不占用耕地等特点,是发展生物质能源的优良物种。通过厌氧发酵将其转化为沼气,不但可以控制互花米草过度生长繁殖,解决其资源化问题,每年还可获得数量不菲的沼气,符合可持续发展的要求。将近年来互花米草厌氧发酵产沼气方面的研究进行了归纳和总结,主要包括互花米草特性、厌氧发酵产沼气的优劣势、可行性及相关研究进展以及今后的研究重点和展望,厌氧发酵产沼气研究进展包括直接发酵、过程控制、预处理、混合发酵和深度气化利用。互花米草中钠抑制的消除、机械收割、厌氧发酵工艺、相关工程技术设备以及能源化利用长效运行管理机制等将是今后互花米草能源化利用研究的重点。
Spartina alterniflora is one of the first ten invasive alien invasive species announced by the State Environmental Protection Administration and the only coastal salt marsh plant. Due to its fast growth rate, strong reproductive capacity, large biomass and non-occupation of cultivated land, it is an excellent species for the development of biomass energy. By anaerobic fermentation to convert it into biogas, it not only can control over growth and reproduction of Spartina alterniflora, but also solve the problem of its resource utilization. It can also obtain a large amount of biogas every year, which is in line with the requirements of sustainable development. In recent years, the research on anaerobic biogas production from Spartina alterniflora was summarized and summarized, including the characteristics of Spartina alterniflora, the advantages and disadvantages of biogas produced by anaerobic fermentation, the feasibility and related research progress, as well as the research priorities and prospects in the future The research progress of anaerobic biogas production includes direct fermentation, process control, pretreatment, mixed fermentation and deep gasification. Sputum reduction of sodium inhibition, mechanical harvesting, anaerobic fermentation process, related engineering and technical equipment and energy use of long-term operation and management mechanism will be the future of Spartina alterniflora research focus.
