2001 Technology for a Sustainable Environment: NSF/EPA Partnership: Biological hydrogen production as a sustainable green technology for pollution prevention (TSE01-D)

0124674Logan该项目旨在开发一种新技术，以从废水中产生基于生物的清洁氢源。 有效转化废水中溶解的有机物的主要障碍是防止种间氢转移，使得通过发酵过程产生的氢不会损失到厌氧微生物中。 为了防止种间转移，负责发酵的微生物将使用双罐膜生物反应器与负责甲烷生产的微生物分离。 膜的目的是控制细胞在第一反应器中的停留时间，使得缓慢生长的产甲烷菌不能存在于第一罐中，因此不能显著降解发酵产生的氢气。 该反应器将以已显示限制悬浮生长反应器中的膜生物污染的模式操作。

0124674LoganThis project is to develop a new technology to create a biologically based source of clean hydrogen from wastewater. The main barrier to efficient conversion of dissolved organic matter in wastewater is preventing interspecies hydrogen transfer so that hydrogen generated through fermentation processes is not lost to anaerobic microorganisms. To prevent interspecies transfer, the microbes responsible for fermentation will be separated from those responsible for methane production using a two-tank membrane bioreactor. The purpose of the membrane is to control cell detention time in the first reactor so that slow-growing methanogens are not able to exist in the first tank and will therefore be unable to significantly degrade the hydrogen produced from fermentation. The reactor is to be operated in a mode that has been shown to limit membrane biofouling in suspended growth reactors.
