Method and apparatus for deodorization using ozone

The invention discloses a method and a device for degrading and deodorizing by using ozone. The device comprises an ozone generation monitoring device and an ozone tail gas monitoring device. The ozone generation monitoring device comprises an ozone generation device, a power controller and a process controller. The power controller is coupled with the ozone generating device and used for controlling the ozone generation amount. The process controller is coupled to the power controller. The ozone tail gas monitoring device is used for monitoring tail gas from a waste gas/waste water environment as sampling gas, and can comprise a device for cooling, dehumidifying, dedusting and removing particles from the sampling gas, and an ozone analyzer. And the ozone analyzer can receive the sampled gas and ozone from the ozone generation device for analysis, and feeds back different ozone concentration signals to the process controller, so that the process controller controls the power controlleraccording to the differe
