Abstract
PURPOSE: To prevent the elution of elements such as Fe, Ni, Cr, F the like into water by adding the neutralized sludge of waste fluoronitric acids after drying into molten slag, thereby contg. said elements into the slag.
CONSTITUTION: After the neutralized sludge of waste fluoronitric acids is dried, the dried sludge is added mixed to and with the molten slag discharged from iron works, etc., so that elements such as Fe, Ni, Cr, F, the like in the neutralized sludge are contained in the slag, whereby the elution of said elements into water is prevented. For example, 5kg dried and neutralized sludge is added to 100kg slag of blast furnaces, converters or electric furnaces, and these are thoroughly mixed to form molten slag. After cooling, part thereof is taken out, and 100g slag is charged into 1l water. After 2 hours, the amt. of elution of elements into water is measured, but no elution into water is admitted.
