Five different mesophilic systems were evaluated in this study for the anaerobic treatment of food waste. Systems A and B were one stage methane with unsonicated and sonicated feeds, respectively, while, systems C and D were two-stage hydrogen and methane with unsonicated and sonicated feeds, respectively. System E comprised a novel sonicated biological hydrogen reactor (SBHR) followed by methane reactor. The results showed that sonication inside the reactor in the first stage (system E) showed superior results compared to all other systems. Overall VSS removal efficiencies of 67%, 59%, 51%, 44%, and 36% were achieved in systems E, D, C, B, and A, respectively. Volumetric hydrogen production rates of 4.8, 3.3, and 2.6L H(2)/L(reactor)d were achieved in the SBHR, CSTR with and without sonicated feed, respectively, while, methane production rates of 1.6, 2.1, 2.3, 2.6, and 3.2L CH(4)/L(reactor)d were achieved in systems A-E, respectively.
本研究评估了 5 种不同的嗜温系统用于处理食物垃圾的厌氧处理。系统 A 和 B 分别为未超声和超声进料的单级甲烷系统，而系统 C 和 D 分别为未超声和超声进料的两级氢气和甲烷系统。系统 E 由新型超声生物制氢反应器（SBHR）和甲烷反应器组成。结果表明，在第一级反应器内进行超声处理（系统 E）比其他所有系统的效果都要好。在系统 E、D、C、B 和 A 中，VSS 的总体去除效率分别达到 67%、59%、51%、44%和 36%。在 SBHR、有和没有超声进料的 CSTR 中，分别实现了 4.8、3.3 和 2.6 L H2/L(反应器)d 的体积产氢率，而在系统 A-E 中，分别实现了 1.6、2.1、2.3、2.6 和 3.2 L CH4/L(反应器)d 的甲烷产率。
