摘要
PROBLEM TO BE SOLVED: To provide a manufacturing method capable of providing a calcium-based compound coating insolubilization material adopted to a reclamation standard defined in Environment Agency notification No.13 by directly treating sludge containing high concentration arsenic.SOLUTION: A calcium-based compound coating insolubilization material adopted to a reclamation standard defined in Environment Agency notification No.13 can be obtained by conducting coating on a primary granulated article obtained by mixing and granulating a sludge containing high concentration arsenic with a cement-based solidification agent with the cement-based solidification agent or a cement-based solidification agent containing alginate by a secondary granulation or by modifying a surface of a secondary granulated article on which cement coating is conducted with alginate.SELECTED DRAWING: Figure 2
