猕猴桃皮中温发酵产沼气潜力的实验研究

Biogas Production Potential of Kiwifruit Peel under Moderate Temperature

文章以猕猴桃皮为原料,在恒温30℃的条件下进行批量式沼气发酵试验,实验设计对照组(120 mL接种物)和实验组(120 mL接种物+25.42 g猕猴桃皮)。实验结果表明:实验组沼气发酵时间为27 d,净产气量为2290 mL,计算得出猕猴桃皮的产气潜力分别为512 mL·g^(-1)TS,522 mL·g^(-1)VS,是一种较好的沼气发酵原料,为废弃猕猴桃皮的资源化利用提供了新的途径。

Biogas fermentation with peel of kiwifruit was studied at 30 ℃ adopting batch fermentation. Control group(120 mL inoculums) and the experiment group(120 mL inoculum and 25.4 g peel of kiwifruit) were designed. The results showed that the fermentation time of experiment group was 27 days with net biogas production of 2290 mL, and gas production potential was calculated to be 512 mL·g^-1TS, or 522 mL·g^-1VS.In a word, it was a feasible raw material for biogas fermentation.
