通过对芦蒿秸秆进行酸、碱预处理和厌氧发酵制沼气实验，比较不同的预处理方法对芦蒿秸秆产气性能的影响。结果表明，与对照组相比，碱处理能较好地改善秸秆的产气性能，其中2%NaOH处理效果最好，发酵初期VFA含量高达4882.34 mg·L-1，比对照组提高了705.21%，单位TS固体产气量为288.42 ml·g-1，较对照组提高了17.08%，甲烷含量最高可达61.14%。

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%.
