Abstract
PURPOSE: To obtain a stabilized product by a method wherein a substance to be fermented is added with an org. substance and fermented in a fermentation tank, thereafter fermented substances are screened and a fraction with a small particle size is recovered as a product and a fraction with a large particle diameter is returned again to the fermentation tank to be sufficiently aged.
CONSTITUTION: An org. substance such as straws saw dusts or a part of a fermented substance is added to a substance to be fermented such as a sludge to adjust a water content and air permeability and, thereafter, a mixed substance is thrown into a fermentation tank to carry out the aerobic fermentation. Subsequently, a formed compost taken out therefrom is screened and a fraction with a small particle diameter is recovered as a product and a fraction with a large particle diameter is mixed again with a next sludge or the like in the fermentation tank as a reflux substance to be subjected to fermentation again. As described above, because the sufficient ageing is carried out, a stable product is obtained.
