【摘要】 为了优化蔬菜废弃物厌氧消化工艺，以白菜、生菜、油麦菜、甘蓝菜和花椰菜5蔬菜的废弃物为原料，采用批量消化工艺，设置5种蔬菜废弃物以及等比例混合物的6个实验组，在35℃±1℃的条件下厌氧消化。结果表明：花椰菜产气速率最快，总产气量也是最多的，花椰菜的原料产气率达到了34.43 mL·g^-1,是白菜原料产气率的3.93倍，但花椰菜废弃物的产CH₄潜力较弱，其CH₄含量仅为42.71%;混合原料产气率比单一原料产气率提高了12.81%,且混合实验组的CH₄含量最高，达到了54.32%。在实际工程中，可直接将混合的蔬菜废弃物粉碎进行厌氧消化处理，不仅能提高产气速率和产气量，还能提高CH₄含量。该研究结果可以为蔬菜废弃物的厌氧消化工程提供一定的指导。更多还原

【Abstract】 In order to optimize the anaerobic digestion process of vegetable waste; Five kinds of vegetable wastes including cabbage, lettuce, lettuce, cabbage and cauliflower were used as raw materials. Six experimental groups of five kinds of vegetable wastes and equal proportion mixture were set up by batch digestion process, and anaerobic digestion was carried out at 35 ℃±1 ℃. The results showed that the gas production rate of broccoli was the fastest, and the total gas production was also the most. The gas production rate of broccoli raw materials reached 34.43 mL·g^-1, which was 3.93 times that of cabbage raw materials. However, the CH₄ production potential of broccoli waste was weak, and its CH₄ content was only 42.71%. The gas production rate of the mixed raw material was 12.81% higher than that of the single raw material, and the CH₄ content of the mixed experimental group was the highest, reaching 54.32%. In practical engineering, the mixed vegetable waste can be directly crushed for anaerobic digestion, which can not only improve the gas production rate and gas production, but also increase the CH₄ content. The results of this study can provide guidance for the anaerobic digestion project of vegetable waste.更多还原
