Microwave sterilization and ozone sterilization differ in many aspects:

1. Sterilization method: Microwave sterilization uses high-frequency oscillation and temperature to sterilize. It can penetrate the inside of objects for comprehensive sterilization. It is usually used for the sterilization of food and medicines. Ozone sterilization uses the strong oxidizing property of ozone to sterilize objects. It mainly sterilizes the surface of objects and can also be used to sterilize gases or liquids inside.

2. Scope of application: The result of microwave sterilization is usually to heat up the material being processed and kill microorganisms. It is particularly effective for polar substances, but cannot effectively treat non-polar substances or metals. Ozone has strong oxidizing properties and can sterilize the surface of any substance, but it cannot penetrate into the interior of a solid.

3. Safety: Microwave sterilization usually needs to be carried out in a closed space, but the human body can be nearby without any impact. Ozone sterilization can be carried out in any space, but the human body must leave, otherwise it may cause harm.
