摘要
[目的]研究银杏叶厌氧发酵产沼气潜力。[方法]以银杏叶为原料,在30℃下进行批量式恒温沼气发酵试验,探讨其产气潜力和产气规律。[结果]银杏叶具有较好的产气潜力,沼气发酵时间为45 d,总产气量为1 945 ml,每克银杏叶可产沼气231 ml,原料TS产气率374 ml/g(TS),VS产气率453 ml/g(VS)。[结论]该研究可为银杏叶厌氧发酵产沼气应用提供参考。
[ Objective ] The research aimed to study biogas production potential of the G. biloba leaf. [ Method] G. biloba leaf as material, batch thermostatic methane fermentation test was conducted at 30 ℃ to study its biogas production potential and rule. [ Result] G. biloba leaf had good biogas production potential, and biogas fermentation time was 45 d. Total biogas production was 1 945 mt, and biogas production per gram of G. biloba leaf was 231 ml. Gas production rate of the TS for material was 374 ml/g （ TS）, and gas production rate of the VS was 453 ml/g （VS）. [ Conclusion] The research could provide reference for application of G. biloba leaf producing blogas.
