摘要
农作物秸秆是一种重要的富含有机质(80%～90%)的生物质能源,因其复杂的晶体结构,不能直接被厌氧菌群利用来生产沼气。因此以秸秆作为原料发酵时,需要进行预处理,使复杂的晶体结构得到破坏,从而易于被厌氧菌群利用。文章综述了国内外用物理法、化学法、生物法、物化法预处理秸秆的相关研究进展,考查了不同预处理方法对厌氧消化效果的影响。
Agricultural crop straws are important biomass energy resources,which are rich in organic content（80%～90%）.It can hardly be utilized by the anaerobic bacteria to produce biogas due to its complicated crystal structure.Therefore,the crop straw should be pretreated by means of destructing the complicated crystal structure so as to be easily utilized by the community of anaerobic bacteria in stalk and straw fermentation.This paper summarized different pretreatment methods including physical,chemical,biological and physic-chemical method at home and abroad.Their effects on straw anaerobic digestion are also discussed.
