摘要

采用氮掺杂芦荟碳（N-C）作为厌氧共发酵的添加剂,研究其和磁场的协同作用对厌氧共发酵系统的甲烷产量、总化学需氧量（TCOD）去除率、pH值、总固体（TS）和挥发性固体（VS）去除率的影响。结果表明：与对照组CK相比,添加N-C可使发酵系统的产气高峰提前、沼气产量增加。给发酵系统施加5 mT的磁场,添加N-C可进一步提升共发酵系统性能。N-C添加剂和磁场协同作用可使产沼气高峰比CK组提前2~3 d,累计沼气产量提高48.4%~101.6%。质量分数为0.30% N-C的添加量使发酵系统获得最高的沼气产量（537.6 mL/g VS）、最高的甲烷含量（59.3%）和甲烷产量（318.8 mL/g VS）、最高的TCOD去除率（79.02%）、最高的TS去除率（44.1%）和VS去除率（55.7%）。最后,解释N-C作为添加剂和磁场在增强厌氧共发酵甲烷产量的协同作用。

Abstract

In this study, aloe peel-derived nitrogen-doped bio-based carbon （N-C） was used as an additive in an anaerobic co-digestion system to investigate the synergistic effect of N-C and a magnetic field on methane production, pH value, and the removal rates of total chemical oxygen demand （TCOD）, total solids （TS）, and volatile solids （VS）. The results show that, compared with the control group, the addition of N-C can improve the gas production peak of the digestion system and increase biogas production. Applying a magnetic field of 5 mT to the digestion system and adding N-C can further improve the performance of the co-digestion system. The synergistic effect of the N-C additive and a magnetic field results in a biogas production peak 2-3 days earlier than that of the CK group, and the cumulative biogas production increases by 48.40%-101.6%. The addition of 0.30% N-C enable the digestion system to obtain the highest biogas production （537.6 mL/g VS）, methane content （59.3%）, methane production （318.8 mL/g VS）, and removal rate of TCOD （79.02%）, TS （44.1%） and VS （55.7%）. This paper explains the synergistic effect of N-C as an additive and a magnetic field in enhancing methane production in anaerobic co-digestion.
