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

0124674 Logan这个项目是开发一种新技术，从废水中创造一种基于生物的清洁氢气来源。废水中溶解有机物有效转化的主要障碍是阻止种间氢转移，从而使发酵过程中产生的氢不会流失到厌氧微生物手中。为了防止物种间的转移，负责发酵的微生物将与负责产生甲烷的微生物分离，使用两箱膜生物反应器。膜的目的是控制第一个反应器中的细胞滞留时间，使生长缓慢的产甲烷菌不能在第一个储罐中存在，因此无法显著降解发酵产生的氢气。该反应器的运行模式已被证明可以限制悬浮生长反应器中的膜生物污染。

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.
