UV disinfection is generally only used for air and instrument surface disinfection. Surgical dressings cannot be treated by UV radiation as a routine method. Ultraviolet radiation is the general term of radiation in electromagnetic spectrum with wavelength from 10nm to 400nm, which can not cause people's vision. In 1801, German physicist Ritter found that the ultraviolet ray could sensitize the photographic negative containing silver bromide at the outer part of the ultraviolet end of the sunlight spectrum, so he found the existence of ultraviolet ray. Too much ultraviolet rays entering the body will cause skin cancer. production Ultraviolet sterilization equipment It can be disinfected after use every day. It should be disinfected two or three times a week. It is recommended that the toothbrush head should be replaced every three months. It can be disinfected every day. The SEGA toothbrush sterilizer I selected should be disinfected for 6-8 minutes each time. It is a good ultraviolet disinfection lamp. It needs to be equipped with a ballast. Mould formation is due to long-term lack of ventilation and humidity, Ultraviolet sterilization equipment programme If ventilation and moisture removal are available, mold will not grow. Since mold has been formed, first kill it with a mold remover, and then put a moisture bag such as a charcoal bag. I often do on-site mildew and odor removal projects. You can sprinkle lime on the corner of the wall or place charcoal in the house to absorb moisture when the house is wet. In addition, don't open the window in foggy or rainy weather. Open the window in good weather to ventilate in time.

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, production Ultraviolet sterilization 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, Ultraviolet sterilization equipment programme 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.

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, which 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. production Ultraviolet sterilization 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, Ultraviolet sterilization equipment programme 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.

According to the source of sewage, sewage microwave ultraviolet water treatment equipment mainly includes production sewage microwave ultraviolet water treatment equipment and domestic sewage microwave ultraviolet water treatment equipment. The former refers to industrial sewage microwave ultraviolet water treatment equipment and hospital sewage microwave ultraviolet water treatment equipment, while domestic sewage mainly refers to sewage generated in daily life, municipal sewage microwave ultraviolet water treatment equipment, etc. Sewage quality includes TSS, namely suspended solids in water, sewage type and proportion, etc. The types of sewage and water quality are different. When choosing ultraviolet sterilization equipment, production Ultraviolet sterilization equipment It shall be configured differently. Water volume mainly refers to the average flow and peak flow of sewage to be treated. Secondly, consider whether the equipment operation time is 24 hours or intermittent water supply. In addition, Ultraviolet sterilization equipment programme In addition, the discharge standards for effluent quality requirements and the bacterial indicators and requirements for sewage inflow and outflow shall be considered, and the number of modules required for the UV sterilization equipment of the sewage microwave UV water treatment equipment, the number of lamps included in the module, and the discharge distance of the module shall be specifically designed. In addition, when selecting equipment, we must first determine the treatment water quantity, water quality, discharge standards and other factors. In the process of model selection, the quality, service life and after-sales service of ultraviolet sterilization equipment should be comprehensively investigated.
