Ultraviolet is a kind of light wave invisible to the naked eye, which exists outside the ultraviolet end of the spectrum, so it is called ultraviolet. Ultraviolet radiation is one of the electromagnetic waves from the sun, and it is usually divided into four categories according to the wavelength. The following is a special form of material operation, which is a particle stream with disconnected particles. Each UV photon with a wavelength of 253.7 nm has an energy of 4.9 eV. Customized Breeding sterilization and disinfection equipment When ultraviolet rays irradiate microorganisms, energy transfer and accumulation will occur, and the accumulation results in the inactivation of microorganisms, thus achieving the purpose of disinfection. When bacteria and viruses absorb more than 3600~65000uW/cm2, it has a strong destructive power to DNA and RNA of bacteria and viruses, Breeding sterilization and disinfection equipment Price It can make bacteria and viruses lose their viability and fecundity, and then eliminate bacteria and viruses to achieve disinfection and sterilization effect. On the one hand, ultraviolet light can mutate nucleic acids, hinder their replication, transcriptional blockade and protein synthesis; On the other hand, the production of free radicals can cause photoionization, which will lead to cell death.
Ultraviolet sterilization equipment is an extremely effective method against microbial pollution in water. However, Customized Breeding sterilization and disinfection equipment In order to effectively disinfect water, microorganisms must be exposed to an appropriate amount of ultraviolet carbon light. Ultraviolet disinfection systems are used in many different applications, Breeding sterilization and disinfection equipment Price From the purification of personal household drinking water to the disinfection of industrial wastewater treatment of the whole urban water supply. UV water treatment is considered to be a safer and more economical method for disinfection of industrial water.
Compared with traditional water disinfection methods such as chlorine disinfection, Customized Breeding sterilization and disinfection equipment Microwave electrodeless ultraviolet sterilization equipment is relatively safe and environmentally friendly. Chlorine agent is used for disinfection. When chlorine kills germs in water, due to its strong oxidation, it reacts with natural organic substances in water and generates disinfection by-products such as trichloromethane and haloacetic acid, Breeding sterilization and disinfection equipment Price They all have potential carcinogenicity and certain mutagenicity to human body. Trichloromethane is also classified as Category 2B carcinogen in the list of carcinogens published by the International Cancer Research Institute of the World Health Organization, which poses a health threat of carcinogenicity, teratogenicity and mutagenicity.
Microwave electrodeless ultraviolet sterilization equipment has high value in microwave ultraviolet water treatment equipment, Customized Breeding sterilization and disinfection equipment It destroys and changes the structure of DNA of microorganisms through the irradiation of ultraviolet light, so that the bacteria will die immediately or cannot reproduce, so as to achieve the purpose of sterilization. The real bactericidal effect is UVC ultraviolet, Breeding sterilization and disinfection equipment Price Because C-band ultraviolet light is easily absorbed by the DNA of organisms, the ultraviolet light of about 253.7 nm is preferred. It is a pure physical disinfection method, which has the advantages of simplicity, convenience, broad-spectrum, no secondary pollution, convenient management and automation. With the introduction of various new designed ultraviolet lamps, the application range of ultraviolet sterilization is also expanding.
During the disinfection process, no toxic and harmful by-products will be produced, the composition and performance of the disinfection water will not be changed, and no secondary pollution will be caused to the water body and the surrounding environment; Reduce chlorine input and residual chlorine, Customized Breeding sterilization and disinfection equipment The chlorine content in the swimming pool water reduces the disinfection by-products, making the swimming pool environment more healthy. Breeding sterilization and disinfection equipment Price Small footprint, safe and reliable operation, simple maintenance and low cost. It can be seen that ultraviolet sterilization has the advantages of sterilization, broad-spectrum sterilization, pollution-free, safe and reliable operation, and no toxic by-products. Therefore, it is increasingly used in engineering.
The sterilization principle of the microwave ultraviolet water treatment equipment is mainly to use the irradiation intensity of the ultraviolet lamp, that is, the radiation intensity emitted by the ultraviolet sterilization lamp, which is inversely proportional to the distance of the irradiated disinfectant. Therefore, when the irradiation reaches a certain level, the disinfectant it is exposed to will stay longer, and the closer it is to the sterilization lamp, the better the sterilization effect will be, otherwise, the worse it will be. So, what are the sterilization principles and application characteristics of the submerged microwave ultraviolet water treatment equipment? Now, let's discuss it with you! After absorbing ultraviolet rays, microorganisms will cause some changes in the structure of nucleoprotein molecules in their own cells, resulting in protein denaturation and breakage on the DNA chain, as well as destruction of cross links in DNA molecules, hydration on cytosine and uracil, and even dimers on adenosine, Because dimerization destroys the normal pairing of purine and pyrimidine, it changes the biological activity of DNA. As a result, the metabolism of microorganisms will be hindered, and they cannot proliferate, produce cells and destroy them; Causes the synthesis of proteins and enzymes in bacteria to be blocked, Customized Breeding sterilization and disinfection equipment As a result, the structure and function will be changed and destroyed, which will lead to the death of microorganisms and achieve the purpose of disinfection and sterilization. Experiments have proved that UV is the most bactericidal in the range of 240nm to 280nm, especially when the wavelength is 253.7 μ m, Breeding sterilization and disinfection equipment Price The germicidal effect of ultraviolet radiation is the best. Because a section of C frequency in the ultraviolet ray is very effective in destroying harmful bacteria or viruses. Because UV can kill bacteria, molds, viruses, unicellular algae and other organisms, UV is the preferred equipment for sterilization in the microwave UV water treatment equipment industry.
