Background

The ultraviolet sterilization disinfection is that ultraviolet rays with proper wavelength can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in cells of a microorganism organism to cause death of growing cells and (or) regenerative cells, thereby achieving the effects of sterilization and disinfection. The ultraviolet disinfection technology is based on modern epidemic prevention science, medicine and photodynamics, and utilizes specially designed UVC wave band ultraviolet light with high efficiency, high intensity and long service life to irradiate flowing water so as to directly kill various bacteria, viruses, parasites, algae and other pathogens in the water.

The ultraviolet radiation dose refers to the amount of ultraviolet rays with specific wavelengths required when a certain bacteria inactivation rate is achieved: the larger the irradiation dose (J/m2) × irradiation time(s) × UVC intensity (W/m2), the higher the sterilization efficiency, and the irradiation time is generally only a few seconds due to the size requirement of the equipment, so the UVC output intensity of the lamp tube is the most important parameter for measuring the performance of the ultraviolet sterilization equipment.

In the prior art, a UV sterilizer is generally used for sterilizing and disinfecting effluent water of an effluent system, and ultraviolet light emitted by the UV sterilizer directly irradiates a water inlet pipe and a water outlet pipe of the effluent system to sterilize and disinfect the effluent water.

In the urban sewage disinfection, the average irradiation dose is 300J/m²The above. Below this value, there is a possibility that the germs are not completely killed by the light, and when they flow out of the channel and are irradiated by the visible light, they are reactivated, and the sterilization effect is lowered. The higher the sterilization efficiency requirement, the larger the radiation dose required. The existing water inlet and outlet pipe is generally in a straight structure, ultraviolet light emitted by the UV sterilizer can irradiate the UPVC pipeline through the straight water inlet and outlet pipe, and the UPVC pipeline is accelerated to age and embrittle by long-term irradiation, so that the pipeline water leakage is caused.
