- 摘要：
The invention provide a technique for the treatment of harmful substances by which the inhibition of soil or ash containing lead, cadmium, mercury, hexavalent chromium, selenium and/or arsenic in a high concentration from dissolving and the decomposition of organochlorine compounds such as trichloro- ethylene, polychlorinated dibenzo-p-dioxins and PCB into harmless substances can be attained economically and effectively. The invention relates to an encapsulating agent which contains sulphide iron ore and an activator and which may further contain soft-burned magnesia, cement, quicklime, slaked lime, magnesium carbonate, limestone, dolomite and/or alkali silicates. The encapsulating agent makes it possible to conduct reliably and economically the inhibition of lead, cadmium, mercury, hexavalent chromium, selenium and/or arsenic contained in soil or ash from dissolving and the decomposition of organochlorine compounds such as trichloroethylene, polychlorinated dibenzo -p-dioxins and PBC into harmless substan
