This study investigated the batch experiments on biohydrogen production from wastes of plant and animal origin. Several substrates including sugar beet pulp (SBP), sugar beet leaves (SBL), sugar beet stillage (SBS), rye stillage (RS), maize silage (MS), fruit and vegetable waste (FVW), kitchen waste (KW) and slaughterhouse waste (SHW) including intestinal wastes, meat tissue, post flotation sludge were tested for their suitability for hydrogen production. Generally, the substrates of plant origin were found to be appropriate for dark fermentation, and the highest hydrogen yield of 280 dm3 H2/kg VS was obtained from fruit and vegetable waste. Contrary to these findings, slaughterhouse waste as well as kitchen waste turned out to be unsuitable for hydrogen production although their methane potential was high. It was also concluded that the combined thermal pretreatment with substrate acidification was needed to achieve high hydrogen yields from wastes.

通过暗发酵从植物和动物来源的废物中生产生物氢

本研究调查了从植物和动物来源的废物中生产生物氢的批量实验。几种底物，包括甜菜浆 (SBP)、甜菜叶 (SBL)、甜菜酒糟 (SBS)、黑麦酒糟 (RS)、玉米青贮饲料 (MS)、水果和蔬菜废料 (FVW)、厨房垃圾 (KW) 和对包括肠道废物、肉组织、浮选后污泥在内的屠宰场废物 (SHW) 进行了氢气生产的适用性测试。一般来说，植物来源的底物适合暗发酵，从水果和蔬菜废料中获得的氢气产量最高，为 280 dm3 H2/kg VS。与这些发现相反，尽管屠宰场废物和厨房垃圾的甲烷潜力很高，但它们并不适合制氢。
