摘　　要：试验研究了不同接种量对易腐垃圾厌氧消化的影响。在垃圾投加量为发酵容积的25％。接种量为发酵容积的12．5％～75％时，垃圾发酵的产氢量与接种量无明显的相关性；当接种量由发酵容积的12．5％提高到37．5％，垃圾的TS降解量、VS降解量、产沼气总量、产甲烷量分别提高了4．2倍、1．6倍、7．9倍、1972．3倍；当接种量由发酵容积的37．5％提高到75％时，垃圾的髑降解量与VS降解量、产沼气总量及产甲烷量无较大变化，但反应的抑制期从25d缩短至15d。试验结果表明，为稳定易腐垃圾厌氧发酵产气，接种量不宜低于发酵容积的37．5％。This paper reported the experiment that the effect of micro-flora seeding volume upon anaerobic digestion of putrescihle rubbish. When the substrate （rubbish） reached 25% of total volume of fermentative reactor, with the increase of micro-flora seeding volume from 12.5% to 75% of the fermentative reactor, hydrogen production was independent of micro-flora seeding volume.With the increase of micro-flora seeding volume from 12.5% to 37.5%, the total solid （TS）, volatile solid （VS） decomposition of the substrate, biogas yield, and methane yield raised 4.2 folds, 1.6 folds, 7.9 folds and 1 972.3 folds respectively. But with the increase of micro-flora seeding volume from 37.5% to 75%, these values had no risen clearly; the stasis time was cut from 25 days to 15 days. To ensure the stabilization of anaerobic digestion process, the seeding volume of micro-flora would be 37.5% above the total volume of fermentative reactor
