This study investigated the feasibility of anaerobic digestion (AD) of potato peel waste (PPW) and its lactic acid fermentation residue (PPW-FR) for methane (CH4) production. The experimental results showed that about 60-70% CH4 content was obtained. The digester using PPW-FR as feedstock exhibited better performance and produced a highest cumulative CH4 production of 273 L/kg VS fed, followed by 239 L/kg VS fed using PPW under the same conditions. However, with increasing solid loadings of PPW-FR feedstock from 6.4% to 9.1%, the CH4 production was inhibited. The generation, accumulation, and degradation of volatile fatty acids (VFAs) in digesters were also investigated in this research.
本研究探讨了马铃薯皮废弃物（PPW）及其乳酸发酵残渣（PPW-FR）进行厌氧消化（AD）以生产甲烷（CH4）的可行性。实验结果表明，可获得约 60-70%的 CH4 含量。以 PPW-FR 为原料的消化器表现出更好的性能，在相同条件下，以 PPW-FR 为原料的累积 CH4 产量最高，达到 273 L/kgVS 进料，其次是 239 L/kgVS 进料。然而，随着 PPW-FR 进料的固体负荷从 6.4%增加到 9.1%，CH4 产量受到抑制。本研究还研究了消化器中挥发性脂肪酸（VFAs）的产生、积累和降解。
