酸碱预处理对芦蒿秸秆厌氧发酵的影响
Effect of acid and alkali pretreatment on anaerobic fermentation of artemisia selengensis straw
摘要
Abstract
In order to compare the effects of different pretreatment methods on gas production performance of artemisia selengensis straw, the straw was pretreated with acid or alkali of different concentrations before anaerobic digestion. Alkali pretreatment could effectively improve the performance of biogas production comparing with the control group, and the 2% NaOH pretreatment was the best. VFA concentration could be up to 4882.34 mg·L-1 at the early stage of anaerobic fermentation in the alkali pretreatment system, which was 705.21% higher than the control group. The gas yield of unit total solid (TS) was 288.42 ml·g-1in the alkali pretreatment system, which was 17.08% higher than control group, and methane content reached 61.14%.关键词
