| 摘 要： | 以新鲜聚合草为发酵原料,在实验室自行设计的发酵装置上进行了厌氧发酵试验,通过测定发酵过程中发酵液和沼气的各项指标,对蔬菜废弃物厌氧发酵的可行性及接种量对发酵过程的影响进行了研究.结果表明,聚合草用厌氧发酵工艺处理是可行的;在试验采用的10%、20%、30%和40%四个水平的接种量中,最佳接种量为20%时,聚合草TS=12.40%的产气率为95.43 mL/g,VS=83.9的产气率为1006.36 mL/g.明显高于其他3组实验.

| Abstract: | A batches of anaerobic digestion experiments for fresh comfrey were conducted in self-manufactured anaerobic equipment. The feasibility of anaerobic digestion of comfrey and the effect of different concentration inoculums on anaerobic digestion were studied. The results showed that the anaerobic digestion can fit for the characteristics of anaerobic fermentation of fresh comfrey. Among inoculums concentrations of 10% ,20% ,30% and 40%, the best concentration of inoculum is 20% and the potential of biogas production with comfrey is 569. 52 mL/g · TS or 84. 17 mL/g · VS. respectively, which were obviously higher than those of other three treatments. This study provided a good reference for the research and development of the comprehensive utilization of fresh comfrey. |
