农业废弃物沼气干发酵技术研究进展

Progress of Biogas Dry Fermentation Technology of Agricultural Residues

我国农业废弃物产量巨大,大部分废弃物因得不到合理利用而被丢弃,造成了环境污染。沼气干发酵技术有较高的废物处理效率,具有运行费用低、有机负荷大、需水量小和产生沼液少等优点,能有效解决农业废弃物的处置和能源化利用问题。综述了厌氧发酵过程机制及农业废弃物干发酵产沼气的研究现状,并对干发酵的应用前景和发展趋势进行了展望。

The output of agricultural waste in our country is huge,most of the wastes are discarded because they cannot be used reasonably,which has resulted in environmental pollution. Biogas dry fermentation technology has higher waste treatment efficiency with the advantages of low operating cost,large organic load,small water requirement and less biogas production. It effectively solved the problems of disposal and energy utilization of agricultural waste. This review summarized the mechanism of anaerobic fermentation process and the research status of agricultural waste biogas production by dry fermentation. The prospect and development trend of dry fermentation were also prospected.
