Self-cleaning water storage tank for secondary water supply

Abstract

The invention discloses a self-purification type water storage tank for secondary water supply, and belongs to the technical field of application of secondary water supply equipment with water quality deep purification and disinfection. The technical problems that ozone disinfection and ultraviolet disinfection are not effectively coupled by existing secondary water supply equipment, the water purification effect is poor, and the water purification cost is high are solved. Comprising a shell, a water inlet, an ozone micro-nano bubble generating device, an aeration port, an ultraviolet lamp tube, a water pumping pipe and a suction pump, the water inlet is formed in the upper portion of the side wall of the shell, the water outlet is formed in the bottom face of the shell, the ozone micro-nano bubble generating device is arranged on the upper portion of the outer side of the shell, the aeration opening is formed in the bottom of the inner side of the shell, the ozone micro-nano bubble generating device is communicated with the aeration opening, the ultraviolet lamp tube is vertically arranged on the inner side of the shell, and the water pumping pipe is made of light-transmitting materials. A spiral water pumping pipe is mounted on the outer side of the ultraviolet lamp tube, a suction pump is arranged on the outer side of the shell, and the water pumping pipe is communicated with the suction pump. The water purification effect and the water purification efficiency are improved. The device is used for water storage and disinfection.
