干式厌氧发酵技术现状与国内应用项目简介

Research and application progress of dry anaerobic fermentation technology

针对当前农业、工业及城市排放中的大量高浓度有机固体废弃物须要进行无害化处理和资源化利用的问题,文章从生物无害化处理的角度对当前的应用技术进行了探讨。从厌氧消化项目示范角度分析了国内外干式厌氧发酵技术工艺研究现状,并结合当前干法发酵工艺及反应器开发的进展,列举了在国内稳定运行的3个干式发酵案例,对各发酵工艺的优缺点进行了阐述。通过对干式厌氧技术及应用现状的阐述与分析,为干式厌氧发酵技术的发展及实际应用提供借鉴和指导。

In view of the situation that a large number of high concentration organic solid wastes in agricultural,urban and industrial emissions need harmless treatment and resource utilization,this paper discussed the perspective of bio-harmless treatment.The research status of dry anaerobic fermentation technology at home and abroad was analyzed from the perspective of anaerobic digestion,and the development of dry fermentation reactor was also discussed in this paper.Finally,3 domestic dry fermentation cases with stable operation were listed,and the advantages and disadvantages of each fermentation process were expounded.Through the description and analysis of the dry anaerobic technology and its application status,the reasonable disposal of organic solid waste will lay the foundation.
