摘要:
为了促进寒区沼气生产，通过在低温条件下对产甲烷菌群的传代富集，以及沼气促进剂的投放，研究提高低温沼气发酵的效果。结果表明：第一代累计产气量100.0 mL，甲烷含量为45%左右，第五代为338.3 mL，第六代则达到了367.7 mL，甲烷含量也增至65%以上；在第五代中筛选出的高效产甲烷菌群中投入促进剂，累计产气量可达到428.0 mL，增加产气率达40%以上，甚至超过了第六代产气效果16.4%。可见，随着代数的增加，菌群数量、产气量均相对增加，启动时间逐渐缩短；而沼气促进剂也能够增加甲烷发酵的效率,从而大幅提高产气量。
Abstract:
In order to promote biogas production，the study on improving the effect of biogas-fermentation was conducted by enrichment of the methanogenic community at low temperature and put in the biogas-fermentation accelerant.The results showed that the total gas production of the first generation was 100 mL,the methane content was about 45%,the fifth generation was 338.3 mL,the sixth generation reached to 367.7 mL,the gas production increased to 65% or more;In addition,put the biogas-fermentation accelerant into the efficient methane-producing microbes of screen out form in the fifth generation,the total gas production reached 428.0 mL,increased the gas production rate above 40%,even more than the effect of the gas production of the sixth generation by 16.4%.Therefore,with the increasing of enrichment generations，the starting time shortened gradually,the gas production and the flora increased;and biogas-fermentation accelerant also could increase the efficiency of methane fermentation,which could greatly improve the gas production.
