Secondary water supply UV sterilization device

Sterilization principletheory-Guangpu Guichuan-

Secondary water supply UV sterilization deviceThe principle of using ultraviolet (UV) radiation for sterilization and disinfection is utilized：

Ultraviolet radiation is divided into three wavelength ranges: A, B, and C, as well as vacuum ultraviolet radiation. A band is 320-400nm, B band is 275nm-320nm, C band is 200-275nm, and vacuum ultraviolet radiation is 100-200nm. C band ultraviolet radiation is used for water disinfection. The theory of light quanta holds that light is a special form of material motion, a flow of particles that are not connected. Each ultraviolet photon with a wavelength of 253.7nm has an energy of 4.9eV.

After being exposed to ultraviolet radiation, microorganisms absorb the energy of ultraviolet radiation, which is essentially the absorption of ultraviolet energy by nucleic acids. Nucleic acid is the fundamental substance and basis of all living organisms, divided into ribonucleic acid (RNA) and deoxyribonucleic acid (DNA)
）The common feature between the two categories is the nucleotide chains connected by phosphodiester bonds based on the principle of purine pyrimidine base pairing. Ultraviolet radiation can cause mutations in nucleic acids, hinder their replication, transcriptional blockade, and protein synthesis. Because DNA has the highest absorption rate around 254nm, ultraviolet radiation has a very good inactivation effect on microorganisms.
Due to different irradiation doses, the forms of damage caused by ultraviolet radiation also vary, mainly in three forms:
1. Adjacent pyrimidines form pyrimidine dimers through covalent bonds, which is a common mechanism of UV damage to DNA;
2. The photolysis products of pyrimidine form dimers on the DNA strand;

3. Covalent bonds are formed between proteins and DNA.Equipment featuresSuperiority

The secondary water supply UV sterilization device, as a specialized equipment for secondary water supply sterilization and disinfection, has the following characteristics:
1. High disinfection efficiency
In hospital sewage treatment, ultraviolet disinfection method has a higher sterilization rate and shorter sterilization time compared to other disinfection methods. The ultraviolet disinfection method can kill common bacteria within one second, while the chloride compound disinfection method requires at least one hour to achieve the same effect as ultraviolet disinfection.
2. Will not generate secondary pollutionGenerally, in hospital sewage, chemical reagents are added for sewage treatment, and disinfecting with chemical materials such as chlorine and ozone can affect water quality. Ultraviolet disinfection does not add any substances to the water
Chemical agents do not pose a secondary pollution threat to water.
3. Will not develop immunity against aquatic organisms
UV disinfection technology is different from other technologies in that it does not induce immunity in microorganisms in hospital wastewater. It only destroys the DNA of microorganisms, rendering cells inactive and unable to replicate. However, using chlorinated compounds for hospital wastewater disinfection can develop immunity against microorganisms in the wastewater over time, leading to a decrease in the effectiveness of wastewater disinfection and treatment.
4. Universality

In hospital sewage treatment, the use of ultraviolet sterilization technology is compared with other sterilization technologies. The use of ultraviolet sterilization technology has a higher universality of sterilization, and it may achieve good killing of all bacteria and viruses.Installation diagraminstallation
