[0002] Secondary water supply refers to the form that units or individuals store and pressurize city public water supply or self-built water supply facilities through pipelines to supply users or self-use. Secondary water supply is mainly established to compensate for the lack of municipal water supply pipeline pressure and to guarantee the water use of high-rise people. The water quality, water pressure and water supply safety of secondary water supply are closely related to the normal and stable life of the people. However, compared with raw water supply, the water quality of secondary water supply is more easily polluted. Since most secondary water supplies need to be provided with water storage tanks, the water storage tanks are difficult to clean and are prone to breed bacteria, algae and other harmful substances, causing pollution to the water body and threatening the health of the people.

[0003] In the prior art, patent No. CN 113653134 A discloses a secondary water supply system anti-pollution method, which belongs to the field of secondary water supply. The secondary water supply system anti-pollution method is provided with a cleaning rod at the bottom of the water tank, and a cleaning tentacle is embedded on the cleaning rod. The cleaning tentacle is swung by the incoming and outgoing water during the day. An external controller controls the electric active polymer to be in an expanded state, and the main rod stretches outward with the branch rod. The impurities in the water body are adsorbed by the adsorption rod in cooperation with the filter layer and the primary activated carbon. The water body is filtered and sterilized by the antibacterial ball, thereby improving the cleanliness of the water body. At night, the electric active polymer is controlled to drive the elastic skin bag to contract, and the cleaning tentacle is retracted into the groove. The cleaning rod is pulled out from the inside of the water tank by using the pulling assembly, and the cleaning tentacle is stretched. The impurities attached to the cleaning tentacle are removed by rotating the motor, thereby reducing the secondary pollution to the water body and improving the practicability.

[0011] Working process and principle: When using, need to clean water tank every interval time or after adding water, ultraviolet ray lamp tube works and air pump works simultaneously, air pump works and sends the air in the upper portion of water tank into the air chamber, then through the distribution of air chamber, moves down through transparent tube, the gas is oxidized to form ozone under the irradiation of ultraviolet lamp tube in the process of moving down, then the ozone air mixture is discharged from transparent tube, the discharged air forms air bubble in water, the air bubble impacts the bottom and side wall of water tank, and causes disturbance to the water in water tank, thereby making the sediment and algae attachment on the bottom of water tank float, at the same time, the ultraviolet light of ultraviolet ray lamp tube irradiates the water in water tank through transparent tube, thereby comprehensively sterilizing the water through ozone combined with ultraviolet light, and inactivating algae, at the same time, water pump works and draws the water in water tank to the upper portion of treatment box through water outlet pipe, filters through filter screen, and then is discharged back to water tank through backwater pipe, thereby filtering the water impacted by air bubble, and the water flow circulation makes the water in water tank move, thereby increasing the contact of water in different positions with ultraviolet light, increasing the disinfection effect, when finishing, water inlet valve is closed, backflush valve is opened, backwater valve is closed, and blow-off valve is opened, thereby water pump works and backflushes the treated water to the lower portion of treatment box, thereby backflushing and cleaning filter screen, and the filtered material on filter screen is discharged through blow-off pipe, realizing the cleaning of filter screen.

[0012] Advantages of the utility model: Efficiently remove sediment and algae Air is sent into the transparent tube by an air pump, and ozone is generated under the irradiation of the ultraviolet lamp. The ozone, in the form of bubbles, impacts the bottom and side walls of the water tank, stripping and suspending pollutants such as sediment and algae deposited on the bottom and walls of the water tank, solving the problem of difficult cleaning of sediment deposited at the bottom of traditional water storage tanks and reducing the hidden dangers of bacterial and algal breeding.

[0013] Ozone and ultraviolet light synergistic sterilization and disinfection The ultraviolet lamp directly irradiates the water body through the transparent tube, combined with the strong oxidizing property of ozone, forming a double sterilization mechanism, effectively killing pathogenic microorganisms (such as bacteria and viruses) in the water, while destroying the cell structure of algae, improving water quality safety and stability.

[0014] Circulating filtration and backwashing function The water in the water tank enters the treatment tank through the water inlet pipe, is filtered by the filter screen, and then flows back to the water tank, forming a circulation to continuously purify suspended pollutants. The backwashing function (when the backwashing valve is opened) can periodically backwash the filter screen to prevent clogging and prolong the service life, while reducing secondary pollution to the water body.

[0015] Automatic and energy-saving operation The system can automatically trigger the cleaning process (such as air pump, ultraviolet lamp, and water pump linkage) through the automatic controller after a certain time or after adding water, reducing manual intervention and improving maintenance efficiency. The combination of bubble disturbance and circulating filtration reduces energy consumption while ensuring uniform mixing of the water in the water tank, enhancing the disinfection effect of ultraviolet light and ozone.

[0016] Comprehensive coverage of transparent tube and ultraviolet irradiation The transparent tube allows ultraviolet light to directly irradiate the inner walls of the water tank and the water body, reducing the blind area of light and achieving comprehensive disinfection of the space inside the water tank, avoiding residual pollutants in the corners.

[0017] Efficient separation of sewage and backwashing The independent design of the sewage pipe and the backwashing pipe ensures that pollutants and backwashing wastewater are discharged through the sewage valve during the cleaning process, avoiding secondary pollution while maintaining the circulation and purification of clean water in the water tank.
