| 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、1 972.3倍;当接种量由发酵容积的37.5%提高到75%时,垃圾的TS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25 d缩短至15 d.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%.

| Abstract: | This paper reported the experiment that the effect of micro-flora seeding volume upon anaerobic digestion of putrescible rubbish.When the substrate(rubbish) reached 25% of total vol-ume 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,biog... |
