Title:
DETOXIFICATION METHOD FOR INCINERATION ASH, AND INCINERATION ASH REGENERATED FERTILIZER
Document Type and Number:
Japanese Patent JP2020078790
Kind Code:
A
Abstract:
To provide a detoxification method for incineration ash which reduces a content of hexavalent chromium, and an incineration ash regenerated fertilizer in which a content of hexavalent chromium is reduced, according to a simple method.SOLUTION: In a detoxification method for incineration ash, incineration ash of biomass resources is mixed with organic waste, and fermented. According to the detoxification method for incineration ash, the incineration ash of biomass resources can be detoxified according to a simple method, since harmful hexavalent chromium contained in the incineration ash is reduced to harmless trivalent chromium by fermenting the incineration ash with microorganisms contained in the organic waste, or by reductive reaction using contact with organic materials contained in the organic waste. Further, an incineration ash regenerated fertilizer contains incineration ash of biomass resources, and organic waste, and is a fertilizer detoxified according to the detoxification method for incineration ash.SELECTED DRAWING: Figure 1
