A two-step anaerobic baffled reactor (ABR-1 and ABR-2) for H2 production from municipal food waste (MFW) was investigated at a temperature of 26 °C. In ABR-1, the average yield of H2 at an HRT of 26 h and OLR of 58 kg COD/m3 d was 250 ml H2/g VS removed. As unexpected; the H2 production in the ABR-2 was further increased up to 370 ml H2/gVS removed at a HRT of 26 h and OLR of 35 kg COD/m3 d. The total H2 yield in the two-step process was estimated to be 4.9 mol H2/mol hexose. The major part of H2 production in the ABR-1 was due to the conversion of COD(particulate) (36%). In the ABR-2 the H2 yield was mainly due to the conversion of COD in the soluble form (76%). Based on these results MFW could be ideal substrate for H2 production in a two-step ABR processes.
采用两步厌氧折流板反应器（ABR-1 和 ABR-2）在 26°C 下从城市食品废物（MFW）中生产氢气。在 ABR-1 中，在 HRT 为 26 h 和 OLR 为 58 kg COD/m3 d 的条件下，氢气的平均产率为 250 ml H2/g 去除的 VS。出乎意料的是；在 HRT 为 26 h 和 OLR 为 35 kg COD/m3 d 的条件下，ABR-2 中的氢气产量进一步提高到 370 ml H2/gVS 去除。两步法的总氢气产率估计为 4.9 mol H2/mol 己糖。ABR-1 中大部分氢气的产生归因于 COD（颗粒状）的转化（36%）。在 ABR-2 中，氢气的产率主要归因于可溶性形式 COD 的转化（76%）。基于这些结果，MFW 可以成为两步 ABR 工艺中生产氢气的理想底物。
