During the 2020 COVID-19 outbreak, ozone disinfection and sterilization played an important role in preventing and controlling the spread of the epidemic. Ozone has strong oxidizing properties and can quickly destroy the cell walls, cell membranes and nucleic acids of bacteria, viruses and other microorganisms, thereby effectively killing them. The following are the specific applications of ozone in the prevention and control of the new coronavirus:

1. Air purification: Ozone can be used to disinfect indoor air and effectively kill viruses and bacteria in the air. During the COVID-19 epidemic, many places have adopted ozone disinfection technology to ensure air quality and reduce the risk of virus transmission.

2. Object surface disinfection: Ozone disinfection technology can also be used to sterilize object surfaces, such as hospital equipment, household items, etc. The surfaces of these objects may be contaminated with the new coronavirus. Ozone disinfection can effectively kill the virus and reduce the risk of infection.

3. Food disinfection: In the food production process, ozone water can be used for soaking and flushing pipelines, production equipment and containers to achieve the purpose of disinfection and sterilization. During the COVID-19 epidemic, ozone disinfection technology can help ensure food safety and prevent the spread of viruses through food.

4. Disinfectant wipes and hand sanitizer: Some disinfectant wipes and hand sanitizer contain ozone components. Using these products can effectively kill viruses and bacteria on hands or surfaces and reduce the risk of infection.

In short, during the outbreak of the new coronavirus in 2020, ozone disinfection and sterilization played an important role in many aspects, effectively reducing the risk of virus transmission and ensuring public health safety.
