| 摘 要： | 分别在五种不同条件下进行了沼气产气对比试验。试验条件分别为:干牛粪,温度为20℃,排气方式分别为持续排气、间歇排气(每天排气4次);干牛粪,温度为35℃,排气方式分别为持续排气、间歇排气;干牛粪与小麦秸秆按质量比1∶1配比的混合物,温度为35℃,排气方式为间歇排气。将原料装入100 L自动生物发酵罐中,并控制发酵温度和压力,检测发酵过程中沼气的日产气量、料液pH及产气中甲烷体积分数。结果发现,在间歇排气条件下,干牛粪与小麦秸秆混合物与相同质量的干牛粪相比总产气量提高约20%,但日产气量降低,产气周期延长近40%。相同质量的干牛粪,在35℃时发酵与在20℃时发酵相比总产气量提高约35%,高峰产气速度提高约1倍;持续排气相比于间歇排气,日产气量提高约1倍,但甲烷平均体积分数降低约10%。
