干法沼气发酵技术作为有机固体废弃物能源化处置与利用的有效途径,发酵过程无沼液消纳问题,反应器容积小,容积产气率高,近年来已逐渐成为世界各国固体有机废弃物资源化技术研究的热点。本文综述了国内外干法沼气工程发酵技术现状和主要发展工艺,分析了沼气干法发酵关键技术设备,并展望了我国有机固体废弃物干法沼气发酵技术的发展趋势。
Dry biogas fermentation technology as an organic solid waste energy treatment and utilization of an effective way, the fermentation process without biogas solution to the problem of small reactor volume, high volume gas production rate in recent years has gradually become the world solid organic waste Resource technology research hot spots. This paper reviews the current status and main development technologies of dry biogas fermentation at home and abroad. The key technologies and equipment of biogas dry fermentation are analyzed, and the development trend of dry biogas fermentation technology of organic solid waste in China is also prospected.
