Description

Technical Field

[0001] The present invention relates to the technical field of secondary water supply equipment, and in particular to an automatic sterilization and disinfection device for a city secondary water supply pump station and a method for using the same. Background Art

[0002] A water pumping station is composed of pumping station structures and main and auxiliary facilities. The pumping station structures mainly include water intake and water diversion structures, water inlet structures, pump rooms, valve wells and other engineering facilities. It is a complex of electromechanical equipment and building facilities that pump water from low places to high places. Secondary water supply refers to a water supply method in which units or individuals store and pressurize urban public water supply or self-built facilities water, and then supply it to users or for their own use through pipelines. It is usually a special water supply method adopted to solve the water pressure problem of residents on high floors. Therefore, secondary water supply is the only option for high-rise water supply. Whether the secondary water supply facilities are constructed and designed in accordance with regulations and the quality of their construction is directly related to the water quality, water pressure and water supply safety of the secondary water supply, and is closely related to the normal and stable life of the people.

[0003] The existing secondary water supply devices have the following problems: most ultraviolet lamps are straight tube type, and the water flows in the sterilization tank in a straight line and quickly. The water contact time is short, the ultraviolet irradiation time is insufficient, the sterilization is not thorough, the water flow direction in the tank is single, the water flow is unevenly distributed, and some areas may not be effectively sterilized; traditional disinfection methods are mostly direct injection or simple stirring, and the disinfectant and water are difficult to fully mix, resulting in inadequate water quality treatment. Therefore, it is necessary to develop an automatic sterilization and disinfection device for urban secondary water supply pump stations with good sterilization effect. Summary of the Invention
