| 摘 要： | 在中试规模下,研究餐厨垃圾高温厌氧消化试验,通过监测餐厨垃圾厌氧消化过程中产气量、气体组成等产气情况和消化液中pH值、SCOD、NH4+-N、VFAs等化学指标含量变化,确定餐厨垃圾厌氧消化的最大有机负荷,并分析餐厨垃圾高温厌氧消化技术的可行性,结果表明,在工程上餐厨垃圾单独进行高温厌氧消化产甲烷具有技术可行性,但难以保证系统长时间安全稳定运行;餐厨垃圾厌氧消化正常运行时最大有机负荷可达2.551 kg VS/(m3.d);当系统有机负荷为2.551 kg VS/(m3.d)时,每天每千克VS最高可产生甲烷量0.622 m3;氨氮对餐厨垃圾厌氧消化产甲烷影响明显;餐厨垃圾中固有Na+含量对厌氧消化产甲烷影响不明显。

| Abstract: | In the pilot scale, the thermophilic anaerobic digestion of food waste was studied. By monitoring the gas situation like gas output and gas composition, and the chemical index changes of pH value, SCOD, VFAs and ammonia,we determined the biggest organic load of food waste anaerobic digestion and analyzed the feasibility of anaerobic digestion of food waste. The results showed that anaerobic digestion of food waste was technically feasible. But it was difficult to guarantee the safe and stable situation for a long time. The maximum organic loading of food waste system could achieve 2.551 kg VS/(m3·d). In the system, 0.622 m3 methane were generated by one kilogram VS per day under the maximum organic loading condition. Gas situation was affected remarkable by ammonia in anaerobic digestion process.The inherent Na+ content in anaerobic digestion process had no significant effect on methane production. |
