PROBLEM TO BE SOLVED: To obtain a low-cost waste water treatment apparatus using advanced oxidation processes. SOLUTION: Waste water is stored in a buffer tank 1 and introduced into a treatment water tank 11 by a waste water supply pipe 2 through a vortex pump 3, a rotary accelerator 4, a flowmeter or pressure gauge 5, a valve 6, and a dispersing machine 7. An oxidizing agent is injected into the waste water and oxygen is supplied from a gas supply pipe 8 to be dissolved during flowing of the waste water through the waste water supply pipe. Microbubbles are generated in the waste water by a microbubble generator comprising the vortex pump 3, the rotary accelerator 4, and the dispersing machine 7. In the treatment water tank 11, treatment water is agitated by an agitator 12. The treatment water in the treatment water tank 11 is returned to the buffer tank 1 through a return pipe 13.
