Abstract: A sterilization and deodorization waste container having dual-wave band ultraviolet lamp tube includes an isolation chamber provided on an inner side of a container lid and a dual-wave band ultraviolet lamp tube installed in the isolation chamber. The dual-wave band ultraviolet lamp tube is capable of simultaneously generating a direct ultraviolet light wave and an ozone ultraviolet light wave. The isolation chamber includes a reflector housing having a light transmitting window facing an inner cavity of a container body. The dual-wave band ultraviolet lamp tube is controlled by a control circuit to turn on to generate the ultraviolets into an inner cavity of the container body while the container lid is closed and to turn off to stop generating the ultraviolet while the container lid is opened.
