MANUFACTURING METHOD FOR HYDROTHERMALLY SOLIDIFIED MATERIAL OF PAPER SLUDGE INCINERATION ASH |
摘要 |
PROBLEM TO BE SOLVED: To provide a manufacturing method for a granular solidified material enhanced in strengths and suppressed in the elution of a harmful component of heavy metals without damaging microporosity/porosity being the original property of paper sludge incineration ash and suitable for a soil improving material having hygroscopicity or water retention. SOLUTION: Water and/or hot water, quick lime and cement are added to incineration ash obtained at the time of incineration treatment of paper sludge and mixed therewith at a temperature from the normal temperature to 98°C to form a granulated molded material. After the molded material is aged, it is subjected to hydrothermal solidifying reaction to manufacture a hydrothermally solidified material of paper sludge incineration ash having a microporous/porous structure.
