摘　　要：综述了搅拌对厌氧消化过程的影响。通过比较,分析目前沼气工程中应用的3种机械搅拌方式,针对秸秆厌氧消化过程中易发生布料不均匀、挂壁、结壳等造成消化率低、容积产气率低、使用寿命短的问题,开发了一种能够适应浮动物料、实现垂直空间大范围搅拌的搅拌技术,介绍了其工作原理并展望了在沼气工程中的应用前景。The impact of stirring on anaerobic digestion process was discussed in this paper. Through the comparison, analysised three kinds of mechanical stirring methods which used in cur-rent biogas plans. According to the problems such as low digestibility value,low volumetric biogas production rate and short life performance resulting from uneven distributed material, wall sticking and encrustation, a stirring technology of Floating type which can adapt to floating raw materials and realize vertical large-area stirring has been developed. The working principle of this technolo-gy was introduced, and its application prospects in biogas plans were proposed.
