ABSTRACT:
An ultraviolet-and-ozone disinfection apparatus200providing an improvement on disinfection, includes a disinfection tank202, a mercury UV lamp210enclosed by a quartz tube208for generating UV light with air trapped between them undergoing UV irradiation to generate ozone, an ozone transmitting tube216, a spiral water transmitting tube215wrapping around the quartz tube in a spiral manner to achieve sufficient disinfection by mixing ozone in water, a sleeve barrel enclosing the spiral tube. Along the entire flow path, water is exposed to UV radiation to achieve sufficient disinfection and reduce excessive ozone that is harmful to human health.
