| 中文摘要: |
| ：以叶菜类大白菜、甘蓝菜、生菜和油麦菜废弃物为发酵原料，在35±1℃的条件下，通过
测定厌氧消化过程中的产气量、甲烷含量、总固体含量、挥发性固体含量各项指标，对4种单一蔬菜
废弃物及4种不同配比的蔬菜废弃物的沼气发酵产气特性和规律进行研究。结果表明：经过30 d
的发酵周期，单一蔬菜废弃物和混合蔬菜均是较优的发酵原料，其中产气潜力最优的是混合蔬菜
组中的大白菜和甘蓝菜质量比为1∶1的实验组5，其原料产气率、TS产气率和VS产气率分别为50、
761和1 035 mL/g；以单一蔬菜废弃物大白菜为原料的实验组1产甲烷潜力最低，平均甲烷含量及
累积产甲烷量分别只有44.54%和616 mL。该实验结果对蔬菜废弃物的工程应用和缓解今后的能
源紧缺具有重要意义。 |
| 英文摘要: |
| The waste of leafy Chinese cabbage, cabbage, lettuce and long leaf lettuce were used as fermentation raw materi⁃
als. Under the condition of 35 ± 1 ℃, the gas production, methane content, total solid content and volatile solid content dur⁃
ing anaerobic digestion were measured. The characteristics and laws of biogas fermentation of four single vegetable wastes
and four different ratios of vegetable wastes were studied. The results showed that after a 30-day fermentation cycle, both
single vegetable waste and mixed vegetables were better raw materials for fermentation, with the greatest methane produc⁃
tion potential in experimental group 5 with a 1:1 mass ratio of Chinese cabbage to cabbage in the mixed vegetable group,
with raw material, TS and VS gas production rates of 50, 761 and 1 035 mL/g respectively. The experimental group 1 with a
single vegetable waste as Chinese cabbage had the lowest methane production potential, with an average methane content and cumulative methane production of only 44.54% and 616 mL. The results of this experiment have important implications
for the engineering application of vegetable waste and the alleviation of future energy scarcity. |
