秸秆和菌糠沼气化利用研究进展

Research Progress on Anaerobic Co-Fermentation of Crop Straws and Mushroom Cultivation Residue

秸秆和菌糠的沼气化利用是一种既经济又环保的农业废弃物处理方式。为了给秸秆和菌糠沼气化利用的理论研究及应用研究提供参考,文章综述了秸秆和菌糠的原料特性、厌氧发酵过程中主要的影响因素和厌氧发酵过程中的关键技术。在关键技术中,重点总结了原料的预处理技术、混合发酵技术和干发酵技术,提出了在秸秆和菌糠沼气化利用中,这三项技术的综合运用是一个新的研究方向。

Utilization of crop straws（ CS） and Mushroom Cultivation Residue（ MCR） to produce biogas were an economical and environmental friendly way of managing agriculture residues. This paper summarized the characteristics of CS and MCR,the influence factors and some key techniques in their anaerobic fermentation. The focuses were put on three key techniques including material pretreatment,anaerobic co-fermentation and dry fermentation. It was proposed that integrated utilization of these three techniques would be a new research direction for the CS and MCR co-digestion.
