Sterilization effect of ozone generator in extensive animal and human experiments
020 ppm, which can be sensed by people when the concentration is sensitive. When the concentration is 0.15ppm, it is the olfactory threshold. Most people can smell it, and that's the hygiene standard. When the concentration reaches 1-10ppm, it is called the stimulation range. In fact, the safe use of ozone can completely guarantee people's health. For more than 100 years, ozone generators have not been used in the world for more than 100 years. Ozone generator The results showed that the germicidal efficacy was effective when the humidity was 70-80%, and poor when the humidity was lower than 45%. Therefore, in general use, especially in the sterile room and ward of Pharmaceutical Workshop, attention should be paid to the environment. Increase the humidity appropriately. When ozone is used for air disinfection, it should be noted that the germicidal efficacy of ozone is the product of the actual concentration of ozone C and the action time t, i.e., k = C × T. the actual concentration C of ozone is the concentration sterilization threshold Cmin. Even if the time is prolonged, I'm afraid it has no bactericidal effect in actual operation. Ozone should be used as ozone generator for air disinfection according to different application space and different sterilization and disinfection purposes. Ozone generation concentration refers to the concentration of 30 minutes in a fixed volume under natural diffusion mode. The unit is mg / m3. Ozone production is calculated by the concentration and time accumulation of ozone. Ozone generation and ozone concentration are the most basic parameters. Therefore, the target of ozone disinfection should be indicated. There are also two general indicators, the ozone safety indicator for the application space and the product service life indicator, which also need to be indicated to users. For general deodorization, deodorization, etc., the concentration is usually no more than 0.05ppm. If used for indoor sterilization, it is generally 0.1-1ppm; higher concentrations are usually required on the surface of objects or ward areas.
