cavitation is the phenomenon of microbubble formation, growth and subsequent collapse or cavitation at very small time intervals (subtle) to release large amounts of energy. The important role of cavitation is to create hot spots, release strongly reactive free radicals, continuous cleaning by turbulence created by the acoustic flow. Cavitation is generally used to degrade contaminants in two ways, free radical attack and photolysis, and the control mechanism of degradation is generally dependent on the relevant contaminants and cavitation intensity, and in turn on the operating conditions of the reactor. At the moment of collapse of cavitation bubbles, local hot spots are formed in the tiny space around the bubbles, extreme high temperature and high pressure are generated, and the extreme environment at the moment promotes the gas and liquid contact surfaces in the bubbles to be rapidly decomposed, namely organic matters are oxidized. The instantaneous high temperature and high pressure of bubble collapse not only promotes the direct degradation of organic matters, but also ensures that the vapor undergoes chain decomposition reaction under the environment:
H 2 O 2 →·HO+·H
·HO+·HO→H 2 O 2
2·H→H 2

On the other hand, with the synergistic effect of the aggravation of cavitation degree, the microfluidics generated in the cavitation area is startedThe mechanical stirring effect is achieved, the contact area of ozone and liquid is increased, and the action time of ozone in the solution is prolonged; due to the thermal effect of cavitation, the water temperature can be increased, and the reaction temperature is properly increased, so that the ozone oxidation reaction is facilitated, and along with the reaction, the ozone is continuously consumed. The synergistic coupling effect of ozone and cavitation promotes each other, so that an enhanced advanced oxidation is formed, the effect is superior to that of simple cavitation or ozone oxidation, and the effect of effectively guaranteeing degradation of organic matters, killing bacteria, viruses and new pollutants is achieved.
