How does ozone generator work?

The ozone generator uses the principle of high voltage discharge to convert oxygen into ozone. That is, high-voltage alternating current is applied to the high-voltage electrode with  an insulator in the middle to let the dry and purified air or oxygen pass through. When the high-voltage alternating current reaches 10-15KV, a blue glow discharge is generated, and the free high-energy ions in the corona dissociate O2 molecules and polymerize into O3 molecules by collision. The output and concentration of ozone vary with the power supply voltage and current added.

Here explains the principle of ozone:

Ozone is a molecule (O2) formed by the combination of three atomic oxygen (O)

When ozone is generated, the third atomic oxygen in the ozone molecular structure will continue to free or escape from the structure (O2 = O2 (oxygen) + O (primary oxygen), and when it escapes, it will produce BOD and COD in the water. Bleaching, decolorization, reducing odor and other oxidation effects. If ozone does not react with other substances, it will decompose into pure oxygen (O2) without secondary pollution. The ozone generator is used to produce ozone gas (O3) Ozone is easy to decompose and cannot be stored. It needs to be prepared and used on site (in special cases, it can be stored for a short time), so it is necessary to use an ozone generator in all places where ozone can be used. The ozone generator is used in water treatment , air purification, food processing, medicine, aquaculture and other fields are widely used.
