ABSTRACT:
A process is disclosed which comprises the steps of: slurrying sludge to be treated; applying ultrasonic radiation to the slurry to decompose dioxins contained in the sludge in a reaction field developed by the application of the ultrasonic radiation and to transfer pollutants including the resulting decomposition products from a solid phase to a liquid phase of the slurry; and separating the slurry into the liquid phase containing the pollutants and the solid phase free from dioxins by solid-liquid separation means.
