摘　　要：运用NADH/NAD^+技术对餐厨垃圾厌氧消化系统内微生物代谢状态进行动态追踪。厌氧消化系统负荷OLR从2.0kg VS/(m^3·d)到8.5kg VS/(m^3·d)整个运行过程中,在不同负荷条件下取样进行NADH/NAD^+分析。实验结果表明:在厌氧消化末期,厌氧消化的NADH/NAD^+的数值急剧的升高,最高达1.36,可以判定厌氧消化系统内的微生物系统代谢平衡崩溃。The objective of this study was to better understand the transition of microbial Metabolic state during the anaerobic digestion （AD） of food waste at different volumetric organic loading rates. Tests were conducted in laboratory scale, single- phase reactors operated at loading rates ranged from 2. 0 kg VS/ （m3 · d） to 8.5 kg VS/ （m3 · d）, the NADH/NAD＋ at different loading rates were analyzed. The experimental results show that at the end of anaerobic digestion, the value of NADI-I/ NAD ＋ increased dramatically to 1.36, indicating that microbial metabolic balance system in the anaerobic digestion system is out of balance.
