Chlorination or silver ion sterilization itself can cause chemical residues. The high-temperature heating water generally adopted by the physical method needs long waiting time and consumes large energy. The mechanical filtration mode can not kill bacteria and viruses, only can play a role in blocking, and the filtration membrane needs to be replaced after the mechanical filtration mode is used for a period of time. The technology of the utility model adopts ultraviolet rays with the wavelength of 265nm to irradiate the bacterial virus, which can destroy the genetic material of the bacterial virus in a very short time and lead the genetic material not to be copied and expressed, thereby killing the bacterial virus, and the prior mercury lamp generates ultraviolet rays and has wide ultraviolet wavelength range. In addition, the mercury lamp contains toxic substances, and has certain danger when being used as a water source for sterilization. And the UVC-LED lamp beads can generate ultraviolet rays with a single wavelength. At the present stage, the UVC-LED water treatment device can only simply irradiate water flow, and when the flow rate of the water flow is too large, the UVC-LED irradiation power is insufficient, so that bacteria and viruses cannot be killed; when the flow velocity of the water flow is too small, the UVC-LED irradiation power is too high, and resources are wasted.
Meanwhile, at the present stage, the photoelectric conversion benefit of the UVC-LED lamp beads is low, most electric energy is wasted in a heat mode due to the 3% photoelectric conversion benefit, and meanwhile, the generated large amount of energy accelerates the temperature rise of the lamp beads and aggravates the light attenuation speed of the lamp beads. The service life of the UVC-LED is shortened, and the use cost of the product is increased.
