An optional particle size range gis selected from a plurality of particle size ranges g and an OHelution amount D is determined by the following procedure. (1) The rate vof OHconcentration increase of the sea water is determined based on the pH measured in an elution test of the slag of the particle size range g. (2) The rate of OHconcentration increase per the specific surface area of the slag A is determined based on the specific surface area sand the rate vof OHconcentration increase of the slag of the particle size range g, and based on the determined rate, the rate v of OHconcentration increase of the slag of each particle size range g other than the particle size range gis determined. (3) The OHelution amount d of the slag of each particle size range g is determined by the equation: OHelution amount d=[rate v of OHconcentration increase]×[settling time t from the sea surface to the visible water depth]×[proportion w in the slag A], and the OHelution amount D is determined by summing up each OHelution amount d.

摘要： PROBLEM TO BE SOLVED: To provide a method capable of suitably reducing hexavalent chromium even for a substance containing powdered chromium oxide which is small in grain size.SOLUTION: In the method, a substance containing reductive sulfur is mixed with a substance containing chromium oxide, and the mixture is treated with steam so that hexavalent chromium contained in the substance containing chromium oxide is reduced. The mixture is made to have a grain size in which the ratio of the grains of a diameter of 2.5 mm or less is not more than 40 mass%, and the mixture having the grain sizes is treated with steam. Since the mixture is adjusted in grain size to be a grain size distribution in which the mixture has a high ratio of coarse particles, steam goes into circulation over the entire mixture layer, which is capable of suitably reducing hexavalent chromium contained in the substance having chromium oxide.

摘要：【課題】スラグの種類を問わず原料として使用できるとともに、凝固収縮孔が生じたり、内部歪みによる破壊が生じたりすることがないスラグ塊状物を、特別な専用設備を要することなく、少ない手間と時間で低コストに製造する。【解決手段】粒子間の空隙率が30vol%以上となるような粒度を有する粒状スラグを層状に敷き詰めてスラグ層を形成し、このスラグ層に溶融スラグを流し込んで粒子間隙に溶融スラグを流入させ、溶融スラグを凝固させることにより、この凝固したスラグと前記粒状スラグとからなるスラグ塊状物を得る。このスラグ塊状物は、粒状スラグが溶融スラグを小さく分断する役割を果たすため、凝固時の収縮による収縮孔が個々の空隙内に分散して生成し、収縮歪みも同様に分散し、さらには、CaO・SiO2鉱物のγ変態に伴い発生する応力も分散される。このため、大きな凝固収縮孔が生じにくく、また、塊状物を破壊に至らしめるような大きな内部歪みが生じにくい。【選択図】図1

摘要： PROBLEM TO BE SOLVED: To provide a treatment method whereby sulfur content and water-soluble Ca content can be effectively reduced in slag containing sulfur and Ca.
SOLUTION: The treatment method comprises steps of: soaking the slag containing sulfur and Ca in a solvent, blowing carbon dioxide into the solvent and adjusting pH of the solvent to 4-10, thereby extracting a sulfur component and a Ca component contained in the slag into the solvent and reacting the extracted Ca component with the carbon dioxide so as to produce calcium carbonate; and recovering the calcium carbonate together with the treated slag. The treatment method enables efficient extraction of the sulfur component and the Ca component contained in the slag into the solvent and fixation of the Ca component as calcium carbonate, thereby effectively reducing the sulfur content and the Ca content in the slag containing sulfur and Ca.
