Abstract

Hazardous wastes such as fly ash and asbestos can be melted by the plasma treatment, which become a block of glassified slag and those volume decreases sharply by 49_??_65% from the original volume. Glassified slag of the fly ash including heavy metals such as Zn, Cu, Fe and so on has an extremely good water-proof capability. The electric conductivity of the solution of 18.8g slag in 700ml distilled water is nearly as same as that of the pure distilled water, being only about 0.1% of the electric conductivity of the solution of the fly ash in the distilled water. The molten asbesto surface becomes a hard skin without needle-like fibers, which has no influence on the human health. As a result, the plasma treatment is very useful for the environmental preservation
