PURPOSE:To obtain a deodorant with high safety effectively deodorizing the acid odor and neutral odor at a low cost by using water granulated slag made by quickly cooling and granulating blast furnace slag as a carrier, combining an oxidizer with it, and molding and hardening the mixture. CONSTITUTION:The blast furnace slag taken out from a blast furnace is a melted material reacted with impurities in iron ore and ash and lime stone, it is made of CaO, SiO2, Al2O3, basic slag with the CaO/SiO2 ratio of 1wt.% or above is quickly cooled and granulated with pressure water. Ferric oxide is used for an oxidizer, its content is set to 0.2-5.0wt.% against the total weight of water granulated slag fine powder, fine grains, and a hardening stimulant. An adequate quantity of water is added to the combined material thus obtained, the mixture is kneaded, granulated, molded into a columnar shape by an extrusion molding machine, and hardened at the ordinary temperature. When an odor is put into contact with a deodorant thus obtained, the acid and neutral components in the malodorous gas are oxidation-decomposed by the oxidizer and adsorbed and neutralized and removed by an alkaline water granulated slag carrier. |
