Description
Technical Field
The invention belongs to the technical field of water sterilization equipment, and particularly relates to a water sterilization device and a manufacturing method of a photovoltaic power generation unit.
Background
Microorganisms in the water body can bring harm to the health of human bodies. Many household electrical appliances that wade with water all have the problem of microorganism breeding such as bacterium. For example, in water storage type water heaters such as heat pump water heaters and electric water heaters, bacteria are bred due to the fact that a part of dead water exists in the inner container, and water quality is discolored and smells; the water outlets of the water dispenser and the water purifier product are kept moist for a long time and are communicated with the air, so that bacteria in the air reversely enter the water pipe from the water outlets, the total number of bacterial colonies in drinking water flowing out of the water outlets reaches more than 1000 CFU/mL, and the bacterial colonies far exceed the relevant regulations of the health department on water quality; the inside of the dish washer and the washing machine is also subjected to microorganism breeding due to the existence of a damp and humid environment. Therefore, it is necessary to provide a sterilizing apparatus in the water body of the wading home appliance.
At present, common sterilization technical means in wading household appliances mainly include high-temperature sterilization, micro-nano metal particle/ion sterilization, ultraviolet sterilization and the like. However, the existing high-temperature sterilization in the water-related household appliances has the problems of unsatisfactory killing effect, high energy consumption and high-temperature safety due to insufficient temperature and short heat preservation time. The micro-nano metal particle/ion sterilization generally selects silver, copper and the like, but the nano silver, the nano copper and the like only act on microorganisms such as bacteria and the like which are in contact with the surfaces of the micro-nano metal particle/ion sterilization and are ineffective to the microorganisms floating in the water body, and the metal ion sterilization technology requires that metal ions must reach a certain concentration to effectively inhibit bacteria/sterilize. In addition, ultraviolet sterilization generally adopts ultraviolet light in a UVC wave band, and has short wavelength and limited penetration effect. Therefore, the problems of high energy consumption, limited sterilization effect, safety risk and the like generally exist in various conventional sterilization means.
