冰糖橙皮发酵产沼气潜力的实验研究

摘要

文章以冰糖橙皮为原料,采取中温(29℃±1℃)的条件下进行批量式沼气发酵试验,实验采用3个不同TS含量的接种物进行发酵,发酵时间分别为45 d,38 d,30 d.实验结果表明,冰糖橙皮在厌氧活化污泥TS为6.58％,8.04％,11.76％的含量下,产气潜力分别为214 mL·g-1TS,245 mL·g-1TS,386 mL·g-1TS;225 mL·g-1VS,258mL·g-1VS,406 mL·g-1VS,是一种可行的沼气发酵原料,为冰糖橙皮提供了新的资源化利用途径.%Biogas fermentation with sweet orange peel was conducted at (29 ℃ ± 1 ℃) by batch fermentation,and 3 different inoculums with different TS concentration of 6.58％ (group 1),8.04％ (group 2),11.76％ (group 3) were adopted,and their fermentation lasted 45 d,38 d,30 d,respectively.The results showed their biogas yields were 214mL · g-1TS,225 mL · g-1VS for group 1;245 mL · g-1TS,258 mL · g-1VS for group 2;and 386 mL · g-1TS and,406mL · g-1VS for group 3.It was a feasible raw material for biogas fermentation.
