摘　　要：[目的]研究不同来源污泥对玉米秸秆厌氧发酵产气效率的影响。[方法]以玉米秸秆为原料,在接种量相同的条件下,研究了4种不同来源污泥对玉米秸秆厌氧发酵日产气量和累积产气量的影响。[结果]4种不同来源污泥的累积产气量依次为颗粒状污泥>河底污泥>浓缩污泥>压滤泥饼。采用颗粒状污泥为接种物的日均产气量和累积产气量最高,分别为3.73 L/kg VS和56.29 L/kg VS。[结论]该研究结果为充分利用秸秆原料,提高能源利用效率,实现能源可持续发展提供了试验基础。[Objective] The aim was to study the effect of sludge from different sources on biogas yield efficiency through anaerobic digestion of corn straw.[Method] The present research studied on daily biogas yield and the accumulated biogas amount through anaerobic digestion of corn straw and sludges from four sources.[Result] The accumulated biogas yields produced from sludges in four sources from high to low were granular sludge,river sediments,concentrated sludge and filtered sludge.The first one proved the highest at 3.73 and 56.29 L/kg VS in daily biogas yield and the accumulated biogas.[Conclusion] The research laid a foundation for full utilization of straw,improvement of energy utilization and sustainable development.
