PRODUCTION OF WATER CLARIFYING MATERIAL BY RECYCLING INCINERATION ASH AS VALUABLE RESOURCE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a water clarifying material by which large amount of the incineration ashes can be utilized as valuable resources. SOLUTION: Incineration ash of municipal refuse is mixed with mineral clay for ceramic raw material at a proper ratio, the mixture is molded to a proper shape, the molding is fused and calcined at a proper temp. to form a pottery base material 2. Then a glaze is applied to the pottery base material 2 and is calcined again at a proper temp. The glaze contains mineral powder having stretching vibrations or deformation vibrations exhibiting maximum molecular vibration spectrum in an infrared wavelength region among molecular vibration spectra of water.
