| 以难降解废弃物——醋糟为原料，通过与猪粪、鸡粪进行混合厌氧发酵，试验了在中温（37℃）不同配比下的厌氧发酵情况。试验发现：醋糟与猪粪最佳试验组的挥发性固体（VS）含量配比为1：3，最终累积甲烷产量为286.51 mL·g-1 VS，稳定阶段的平均协同增益产气率为7.71%；醋糟与鸡粪最佳试验组的挥发性固体含量配比为1：3，累积甲烷产量为312.57 mL·g-1 VS，稳定阶段的平均协同增益产气率为2.8%。结果表明醋糟与猪粪、鸡粪混合厌氧发酵具有良好的发酵潜力，以及较高的物料协同性，可以使用该方法有效处理醋糟。 |
| 英文摘要: |
| Co-digestion has gained wide attention due to its great compatibility and synergy with raw materials. Vinegar residue is not easily degraded as a single feed under normal anaerobic conditions. Therefore, in this study, it was mixed with pig and chicken manure for codigestion at medium temperature (37℃) to enhance its value. Through a series of systematically designed batch experiments, it was found that the optimum vinegar to pig manure ratio of volatile solids was 1:3, with the final cumulative methane production capacity up to 286.51 mL·g-1VS, demonstrating a synergistic gain of 7.71% in total methane production. The optimum ratio of volatile solids and cumulative methane production for vinegar and chicken manure mixture were 1:3 and 312.57 mL·g-1VS respectively, while the average synergistic gain in the methane production was 2.8%. On the other hand, the effect of co-digestion on the methane concentration in the biogas was insignificant when pig manure was used; and for the case where chicken manure was utilized, the methane concentration decreased with increasing vinegar residue content. Nonetheless, the results demonstrate the synergistic co-digestive effect between vinegar residue and animal manure, suggesting the potential application of anaerobic co-digestion technology to treat vinegar residue. |
