Two step methane fermentation process by controlling hydrogen metabolism in organic acid fermentation tank

摘要

The present invention relates to a two-step methane fermentation process by controlling the hydrogen metabolism of an organic acid fermentation tank, more specifically, to a method for controlling the oxidation-reduction potential of an organic acid fermentation tank by changing a stirring speed, passing an oxygen-To a two-stage methane fermentation process by controlling the hydrogen metabolism of an organic acid fermentation tank capable of controlling hydrogen metabolism or hydrogen partial pressure.
