Ecological hydrogen production in anaerobic wastewater treatment process

As a new clean energy source and important material, the use and demand of hydrogen are increasing-rapidly. So that bio-hydrogen producing technology moves toward cutting down the operation costs in recent years. Bio-hydrogen production capacity improvement and cost reduction are two key points for industrialization of the process. The paper focuses on: Mixed fermentative bio hydrogen production system; fermentation types and their engineering control; the integrated processes with bioengineering and wastewater treatments. In a closed ecologic niche in organism hydrogen-producing fermentation reactor, non-organism factors to influence organism fermentation rate and fermentation product ingredient normally contain temperature, pH and organic elements etc. The new concept was edited and that is Ecological Hydrogen which comes from mixed fermentative wastewater treatment system.
