| 中文摘要: |
| 为提高生物天然气的生产质量与效率，开展污泥复合有机物厌氧消化生产生物天然气技术研究。通过探讨厌氧消化的技术原理、工艺流程及关键步骤（如水解、酸化、脱氢、甲烷化等），分析了微生物种群结构与功能，揭示了不同混合比例、预处理方式及消化温度对厌氧消化效率与产气率的影响机制，并提出了优化方案。结果表明，该方案在显著提升生物天然气产量的同时，有效提高了天然气中甲烷的含量，进一步提升了产品的整体质量。 |
| 英文摘要: |
| To improve the quality and efficiency of biogas production, this study investigates the technology of biogas production via anaerobic digestion of sludge composite organic matter. The technical principles, process flow, and key steps of anaerobic digestion are examined in depth，including hydrolysis, acidification, dehydrogenation, and methanogenesis. The structure and function of the microbial community are also analyzed. Based on these analyses, the mechanisms by which different mixing ratios, pretreatment methods, and digestion temperatures affect anaerobic digestion efficiency and gas yield are revealed. An optimization scheme is proposed accordingly. The results demonstrate that the proposed scheme significantly increases biogas production while effectively enhancing the methane content of the biogas, thereby further improving the overall product quality. |
