| 中文摘要 |
| 在中温（35 ℃）条件下，应用连续式单级高固体厌氧消化技术对有机垃圾进行了实验室规模的处理研究.在启动阶段，垃圾进料量随反应器内pH值及产气量的变化作适当调节.结果表明，在反应器进料有机垃圾的含固率（TS）达到24.79%，挥发性固体物质（VS）达到230.62 g/kg的情况下，系统的产气效率以进料VS计达到了705.77 L/kg.反应器启动30 d后，内部料液的pH值稳定在6.9～7.3之间.在稳定运行阶段，以进料VS计，高固体厌氧消化反应器的有机负荷率（OLR）达到6.98 kg/(m3·d)，水力停留时间（HRT）为35 d，启动实验取得了较为理想的效果. |
| 英文摘要 |
| Under mesophilic condition (35 ℃), a bench-scale experiment based on high solid anaerobic digestion process was conducted in a fed-batch single phase reactor. At the start-up stage, the feeding amount of organic waste was modified with the variation of pH value and gas production. The results of this stage showed that 705.77 L of gas production per kg VS added was obtained while the total solids content of the feeding waste was 24.79% and the VS content was 93.04% of TS. After 30 days of the start-up, the pH value ranged between 6.9 and 7.3 in the reactor, and after 50 days the organic loading rate (VS) reached 6.98 kg/(m3·d) with an HRT of 35 days. |
