以人工有机固体废弃物为对象，在实验室规模上对相分离两级厌氧工艺进行了研究和评价。产酸工艺与后续的填充床产甲烷工艺相结合，既注重产氢，又注重固体物质的增溶效率。在产氢或增溶操作的流出物中，在产甲烷时达到的最大允许OLR高于单一产甲烷过程。产氢操作比溶解化操作更适合于联合收割机产甲烷工艺，因为产氢操作的停留时间比溶解化操作短得多，对COD和VSS的总体去除率几乎相同。产酸工艺中的产氢操作和产甲烷工艺的组合在25 h的总保留时间下产生约442 mmol 1-反应器（1）天（-1）的甲烷和199 mmol 1-反应器（1）天（-1）的氢气，表明82%的COD去除率和96%的VSS分解率。(c)2006爱思唯尔有限公司保留所有权利。
Phase-separated two-stage anaerobic process was examined and evaluated using artificial organic solid waste in laboratory scale. Acidogenic process, which was combined with subsequent methanogenic process using packed-bed reactor, was operated emphasizing on either hydrogen production, or solublizing efficiency of solid materials. In either effluent from hydrogenogenic, or solublizing operation, maximum allowable OLR achieved at methanogenesis was higher than the single methanogenic process. Hydrogenogenic operation was more suitable to combine methanogenic process than solublizing operation, since retention time of hydrogenogenic operation was much shorter than the solublizing operation, obtaining almost the same levels of overall removal efficiency in both COD and VSS. The combination of hydrogenogenic operation in acidogenic process and methanogenic process produced approximately 442 mmol 1-reactor(1) days(-1) of methane and 199 mmol 1-reactor(1) days(-1) of hydrogen at 25 h of total retention time indicating 82% of COD removal with 96% of VSS decomposition.
