Background
Many infectious diseases of human beings are transmitted by microorganisms (viruses, bacteria and fungi) through air or aerosol, the currently widely adopted chemical reagent disinfection method has great harm to human bodies, environment and ecology and fatal danger to respiratory patients, and most of chemical disinfectants can remain in the environment and have irreversible influence on environmental ecology.
Uv disinfection is a broad spectrum of non-chemical disinfection techniques used for microbial inactivation in commercial, industrial and medical environments. When the microorganism is exposed to ultraviolet sterilization wavelength, the DNA or RNA of the microorganism absorbs ultraviolet rays, and the nucleic acid of the DNA or RNA is destroyed, so that the DNA or RNA cannot be split and propagated, loses activity and is no longer infectious. Ultraviolet rays can rapidly inactivate microorganisms including coronavirus, and SARS virus treatment in 2003 and subsequent domestic and foreign experiments are verified.
The current ultraviolet germicidal lamp, namely the medical ultraviolet lamp widely used at present, complies with the technical standards of disinfection of medical institutions (WS/T367-2012), the ultraviolet germicidal lamp (GB 19258-2012) and the technical standards of disinfection (2002). A low pressure mercury lamp was used. The emission lines of the ultraviolet light-emitting diode have 253.7 nm, 184.9 nm, 313.2 nm, 365.0 nm, 404.7 nm, 546.1nm and the like, wherein 253.7 nm and 184.9 nm can destroy DNA of microorganisms, and 184.9 nm ultraviolet light can also oxidize oxygen (O) in air2) Becomes ozone (O)3) Ozone itself also has a bactericidal effect and can cause the harm of difficult breathing, lung function reduction, central nervous system damage and the like. Other long-wavelength ultraviolet light has weak bactericidal effect but is harmful to human health, and can cause illumination dermatitis, erythema, itching, blister, edema and the like on the skin; severe also causing skin cancer; ultraviolet rays can also act on the central nervous system, and headache, dizziness, body temperature rise and the like appear; acting on the eyes, it can cause conjunctivitis, keratitis, called as ophthalmia with illumination, and possibly induce cataract.
