Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a contaminant-containing solid treatment method which is inexpensive, excellent in practicality and enables contaminant to be concentrated and separated without generating extra waste.SOLUTION: The contaminant-containing solid treatment method is provided that comprises: a mixing step (step S1) of mixing a contaminant-containing solid with a powdery agent including a component to react with water and a magnetically attracted component in the presence of water; and a magnetic separation step (step S2) of magnetically separating a mixture obtained in the mixing step. The mixing object to be mixed in the mixing step has a predetermined water content, while the magnetic separation object to be separated in the magnetic separation step has another predetermined water content. The agent is one or more kinds selected from water-granulated slag powder, air-cooled slag powder, and blast furnace slag fine powder 8000.SELECTED DRAWING: Figure 1
【課題】安価で実用性に優れ余分な廃棄物を発生させることなく、汚染物質を濃縮分離可能な汚染物質を含有する固体の処理方法を提供する。【解決手段】水分存在下で、汚染物質を含有する固体と、水と反応する成分及び磁着成分を含む粉末状の薬剤とを混合する混合工程(ステップS1)と、前記混合工程を経て得られる混合物を磁力選別する磁選工程(ステップS2)と、を備え、汚染物質を濃縮し分離することが可能な汚染物質を含有する固体の処理方法において、前記混合工程の混合対象物である被混合物の含水率は、予め定める特定の含水率であり、前記磁選工程の磁選対象物である被磁選物の含水率は、予め定める特定の含水率であり、前記薬剤が、水砕スラグ粉砕物、徐冷スラグ粉砕物、高炉スラグ微粉末8000のうちから選ばれる1種以上である。【選択図】図1 |
