Abstract
PURPOSE: To make cyan-contg. sludge non-pollutive securely and at a low cost by adding and mixing the blast furnace slag discharged from a blast furnace to and with said sludge.
CONSTITUTION: Cyan-contg. sludge 1, cement 2, industrial water 3 and blast furnace slag 4 ground to about ≤32 meshes, more preferably about ≤100 meshes with a grinding machine 5 are put into a mixing tank 6, and are kneaded with an agitator. This mixture is granulated with a granulator 7, and the granules are stored in a storage tank 8. It is preferable to add about 25 parts powder of the blast furnace slag based on 100 parts sludge. Thereby, the elution of cyan is suppressed effectively, and is utilized adequately for land reclamation and others.
