The invention has two working modes of cavitation single action and cavitation cooperating with the plasma water treatment technology. The independent cavitation action means that untreated liquid enters the self-oscillation cavitation cavity through the inlet pipe, large-range cavitation is formed in the cavitation cavity, cavitation bubbles are rapidly collapsed to form a high-temperature high-pressure environment, and steam is cracked in the high-temperature high-pressure environment to generate hydroxyl radicals (OH) with strong oxidizing property. And at the outlet a cavitation jet will be formed. The cavitation jet flow is converged at the center of the impact cavity and impacts, and uncorrupted bubbles in the cavitation jet flow are split into micro bubbles in the impact area, so that the surface area and the surface energy of the bubbles are increased, and the surface oxidation reaction is enhanced. Particularly, the strong micromixing action in the collision area increases the contact probability among reactants, and the pressure fluctuation changes the molecular energy and the distribution thereof, so that the cavitation is effectively enhanced, the vaporization processes of the formation, growth and collapse of the vacuoles in the liquid are more violent, the chemical bond breakage of water molecules in the cavitation bubbles is accelerated, and the yield of hydroxyl radicals OH is further improved. The working mode of the cavitation and plasma water treatment technology is that on the basis of cavitation, negative pressure formed in the self-excited oscillation cavitator is utilized to introduce plasma generated by a plasma discharge device into a cavitation process through an air inlet pipe, a series of chain reactions are continuously induced, and hydroxyl radicals OH continuously participate in the consumption and generation of the chain reactions, so that the macroscopic existence time of the hydroxyl radicals OH is greatly prolonged. And the combination efficiency is increased by several times through the high-efficiency mixing of the self-oscillation cavitator.
The self-oscillation cavitation cavity shown in figure 1 has an optimal structure found by numerical simulation and experiments. With its optimum structure, a large cavitation area can be obtained and the yield of hydroxyl radicals OH is the highest. All cavitator parameters were the same for the reactor.

The inner hole of the flange is a threaded hole, the flange is in threaded fit with the liquid inlet pipe, the distance between the nozzles is changed by adjusting the screwing length of the threads, and the collision strength of cavitation jet is adjusted. The liquid inlet of the cavitator can be connected with a pressure regulating valve to regulate the inlet pressure of the cavitating cavity, and the collision strength is further regulated. Different collision distances and different inlet pressures of the self-oscillation cavity have different cavitation intensities, so that the optimal degradation can be achieved by adjusting parameters of the system according to the types of organic matters of the sewage and the concentration of pollutants.
The upper cover plate, the lower cover plate and the self-oscillation cavitator are made of transparent materials, so that the visualization in the cavitation and collision processes is realized.
In order to extend the cavitation inside the self-oscillating cavitator to the outside of the cavitator, it is necessary to maintain the pressure condition of the jet formed inside the self-oscillating cavitator after the jet is ejected. Therefore, the liquid outlet is arranged on the upper cover plate of the reactor, so that the impact cavity is filled with liquid, the environment condition of submerged jet is created, the external environment of cavitation jet does not change rapidly after leaving the self-oscillation cavitator, and the cavitation area is enlarged. And provides cavitation jet conditions for the impinging stream.
