Title:
METHOD FOR PROMOTING ANAEROBIC DIGESTION BY USING CARBONYL IRON
Document Type and Number:
WIPO Patent Application WO/2023/197342
Kind Code:
A1
Abstract:
The present invention relates to the technical field of biological fermentation, and particularly, to a method for promoting anaerobic digestion by using carbonyl iron. The method comprises: adding carbonyl iron into a fermentation feed for anaerobic digestion. By using carbonyl iron in anaerobic digestion, the anaerobic digestion effect can be improved, and the yield of methane is improved. Carbonyl iron can accelerate the degradation of complicated organic matters by promoting microbial iron respiration, and provides a supplemental source of the necessary iron element for microorganisms, thus having a promotion effect on both hydrolysis-acidification bacteria and methanogens.
