PURPOSE:To effectively recover generated heat, by arranging a rotor having undulated parts and a stator in a state close to each other and connecting the rotor to a rotary driving means. CONSTITUTION:A rotor 4 is rotated at 1,500-7,200 rpm by a rotary driving means 10 to continuously introduce ozone-containing air from a waste water introducing pipe 7. Waste water and ozone-containing air are stirred at a high speed by rotating the rotor 4 at a high speed and high speed shearing surfaces are formed between the perforation parts of the perforated plates 3 of a stator and the rotor 4, both of which provided so as to approach each other, and between the perforation parts and the plate parts to generate strong cavitation in waste water. By this mechanism, cavitation air bubbles are generated while the generated air bubbles are suddenly compressed in the compression stage of compression and expansion to generate high temp. and charge is generated on the surfaces of air bubbles to ionize the substance in each air bubble. Thus, reactivity is enhanced and the generated heat is recovered by a heat exchanger 19.
