摘要: 以波斯菊(Cosmos bipinnata Cav.)秸秆为原料,在恒温(30±0.5) ℃的条件下进行批量式沼气发酵试验,设计对照组(120 mL接种物)和试验组(120 mL接种物+11.91 g波斯菊秸秆)。结果表明,试验组沼气发酵时间为33 d,净产气量为3 248 mL,计算得出波斯菊秸秆的总固体含量产气潜力为289 mL/g,挥发性固体含量产气潜力为282 mL/g。

Abstract: A batch biogas fermentation experiment was carried out with the straw of Cosmos bipinnata as raw material at (30±0.5) ℃ at constant temperature. The control group (120 mL inoculum) and the experimental group (11.91 g straw of Cosmos bipinnata) were used to test the biogas fermentation. The results showed that the biogas fermentation time of the experimental group was 33 d and the net gas production was 3 248 mL. The gas production potential of the straw of Cosmos bipinnata was calculated, and the gas potential of total solid content was 289 mL/g, and the gas potential of volatile solid content was 282 mL/g.

Key words: Cosmos bipinnata Cav., biogas fermentation, potential for gas production
