Disinfection Mechanisms of UV Light and Ozonization

ABSTRACT

Ultraviolet (UV) and ozonization technology are efficient physical processes for the disinfection of bacteria and viruses. At present, due to the outbreak of the novel coronaviruses (SARS-CoV-2) around the world, it is imperative to seek effective disinfection methods for the SARS-CoV-2. In this paper, the disinfection mechanisms of UV and ozone were analyzed, and many studies on the inactivation of similar coronavirus such as SARS-CoV and MERS-CoV by UV and ozone were reviewed. The feasibility on the application of UV and ozone to inactivate SARS-CoV-2 was discussed.
