摘要

在引种到印度的杂草中,紫茎泽兰(Eupatorium odoratum L.)是一种多产的生物质生产者,可用于能源生产。由于新鲜收获的生物质含有参与甲烷生成的微生物抑制剂,因此在厌氧消化之前研究了浸出和部分好氧分解对沼气生产的影响(1.0 m3中试批量发酵罐)。经过预处理的废物产生的沼气比未经处理的废物多约70%,并且纤维素分解细菌和产甲烷细菌的数量也比未经处理的废物高。

Biogas production by anaerobic digestion of Eupatorium odoratum L.

Eupatorium odoratum L. is a prolific producer of biomass among the weeds introduced into India and it can be used for energy production. Since freshly harvested biomass contains inhibitors of microorganisms involved in methanogenesis, the effects of leaching and partial aerobic decomposition of the weed before anaerobic digestion were studied (1·0 m3 pilot-scale batch fermenters) in relation to biogas production. About 70% more biogas was produced by the pretreated waste, and it also gave a higher count of cellulolytic and methanogenic bacteria than the untreated material.
