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 Microwave drying 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, Microwave drying 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.
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 Microwave drying 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, Microwave drying 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.
The power supply is the foundation and should be used carefully. Generally, it needs to work under 200V/50Hz AC power, production Microwave drying equipment In order to ensure the correct operation of the complete set of automatic water softening device. Microwave drying equipment programme The manufacturer of the microwave and ultraviolet water treatment equipment shall ensure that the power cannot be cut off, and that the switch of the equipment cannot be cut to the point, so as to prevent the quality problems of the softening microwave and ultraviolet water treatment equipment and the increase of equipment loss.
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 Microwave drying 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, Microwave drying 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.
Because of the high intensity of water bodies in North China, the cooling and circulating water for central air conditioning is cooled by drinking water, production Microwave drying equipment The common phenomenon is scaling, oxygen erosion and microbial sludge. The purpose of the microwave ultraviolet water treatment equipment is to reduce the three major drawbacks of scaling, erosion and algae growth, which requires the addition of various drugs to the system software, Microwave drying equipment programme According to the working conditions of equipment, materials and water bodies in various regions of various enterprises, the Drug Secret 1 prescription should be effectively matched to improve quality and efficiency, stabilize water bodies and achieve synergy, reduce the amount of drug sludge and sewage microwave ultraviolet water treatment equipment, control costs, and achieve the goal of water conservation, energy conservation and prolonging the service life of equipment.
The sterilization principle of microwave electrodeless ultraviolet sterilization equipment is to use the sterilization ability of ultraviolet light. Can ultraviolet light directly kill microorganisms? Microwave drying equipment programme According to different biological effects, ultraviolet light is generally divided into four parts according to wavelength: A-band (UV-A), production Microwave drying equipment Also known as black spot effect ultraviolet (400 ~ 320 nm); B band (UV-B), also known as erythema effect ultraviolet (320 ~ 275 nm); C-band (UV-C), also known as sterilization ultraviolet (275 ~ 200 nm); D-band (UV-D), also known as vacuum ultraviolet ray (200-100 nm). C-band ultraviolet light is mainly used for water disinfection.
