光能型沼气生物脱硫反应器研究进展

Research Progress of Phototrophic Microbial Reactor Removing Hydrogen Sulfide from Biogas

文章介绍了不同种类的光能型沼气生物脱硫反应器,并指出了该研究领域目前所存在的主要问题:此类反应过程需要辐射能,当单质硫颗粒出现后,液相趋于混浊且透光率明显下降,从而干扰微生物代谢活动;另外,分离单质硫颗粒则需要动力或药剂消耗,从而增加运行成本。

This paper introduced different types of phototrophic microbial reactor removing hydrogen sulfide from biogas. The main problems in this field were pointed out that the process needed radiant energy. When the elemental sulfur parti- cles appeared, the liquid phase became turbid and the light transmission rate decreased obviously, which interfered with microbial metabolic activities. Separation of elemental sulfur particles required power consumption or chemical agentia, and that would increase the operation cost.
