Abstract:
A method for treating a material contaminated with a hazardous substance which comprises drying the material to be treated, admixing the dried material with at least one of calcium oxide and a material containing calcium oxide, and subjecting the resultant mixture to a mechanochemical treatment. A product formed by the above treatment can be solidified by a process comprising admixing the product with an inorganic powder capable of forming a hydrate, and the resultant solid product can be used as a material in civil engineering work, construction or the like. The method can be employed for treating the incineration ash, fly ash from a dust collector, collected dust, or soil which is contaminated with dioxins, and the soil contaminated with polychlorinated biphenyl.
