A method for producing organic matter in compost while preventing malodors using an odorless fermentation decomposition solution for organic matter.

摘要

PPROBLEM TO BE SOLVED: To provide a liquid for promoting odorless fermentation and decomposition of an organic substance that swiftly decomposes an organic substance such as seafood debris, stock excreta, foodstuff debris, garbage, meat debris and sludge while preventing and controlling malodor thereof, and a method for manufacturing compost from the organic substance under odor control using the liquid. PSOLUTION: The liquid for promoting odorless fermentation and decomposition of an organic substance is produced by hot-sterilizing at 70-80C a nutriment liquid prepared by adding molasses and rice bran to water heated to 30-40C, adding lactic acid bacteria separated from cereal as a primary and spawn containing yeast after cooling to perform fermentation, and adjusting pH to 3.0-4.0. The method comprises mixing the above produced liquid with the organic substance, adjusting water content for a raw material for odorless compost, leaving stacked for 24-48 hours, subjecting to anaerobic fermentation at 35-50C under odor control leading to a histolysis state, subsequently starting aerobic fermentation by air blow and stirring and continuing aerobic fermentation for about two weeks while overturning the stack of the organic substance once a day.
