UV sterilization
DAWT·2022-05-09
Introduction
As a commonly used physical disinfection method, ultraviolet disinfection technology is currently widely used disinfection technology. Since the discovery of ultraviolet disinfection and sterilization in the last century, with the continuous development of science and technology, the share of ultraviolet sterilizers in the field of disinfection is also increasing. Ultraviolet sterilizer is a device that utilizes the principle of ultraviolet sterilization.
We all know that the tap water we usually use looks clean, but there are many bacteria in it that we can't see with the naked eye, so we need to take it seriously. We must know that bacteria are everywhere around us, so it is possible for any kind of bacteria to hide in tap water. Therefore, we must take corresponding measures to deal with it. Among many sterilization and disinfection equipment, UV sterilizers are used more.
The ultraviolet sterilizer uses the radiation intensity of the ultraviolet lamp tube, that is, the emitted radiation intensity passes through the ultraviolet germicidal lamp, and the distance between the ultraviolet germicidal lamp and the irradiated disinfectant is inversely proportional. When the irradiation intensity is constant, the longer the irradiated disinfectant stays, the closer it is to the disinfection lamp, the better the disinfection effect, and vice versa. The device can be used in direct drinking water equipment to obtain good water purification effect.
Sterilization principle
Ultraviolet sterilization is the use of ultraviolet rays of appropriate wavelengths that can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, causing growth cell death and/or regenerative cell death, and achieve sterilization and disinfection. Effect. Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics. It uses specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet light to irradiate flowing water to remove various bacteria, viruses, parasites, algae and Other pathogens kill directly.
