UV disinfection introduce www.gyzwx.com www.gyxdq.com 13833174989 UV disinfection is a physical method, which does not add any substance to the water, no side effects, it is better than chlorination, UV disinfection where UV disinfection usually in combination with other substances, a common joint process are UV + H2O2, UV + H2O2 + O3, UV + TiO2, so that disinfection would be better. I'll give you the first paragraph changed a bit. UV disinfection is the use of appropriate wavelengths of ultraviolet light can damage the body's cells microbial DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the molecular structure, resulting in the growth of cell death and (or) regenerative cell death, achieve sterilization effect. UV disinfection technology is based on a modern epidemic, medicine and photodynamic foundation on, UVC band ultraviolet irradiation water use specially designed high efficiency, high strength and long life, the water and all kinds of bacteria, viruses, parasites, algae and other pathogens directly kill to achieve the purpose of disinfection. After the area and water UV disinfection UV disinfection advantages typically available for gas supply difficulties and sub-salt disinfection byproducts have strict limits on the occasion. When the water temperature is generally considered lower ultraviolet disinfection more economical. Mainly by microorganisms (bacteria, viruses, spores and other pathogens) radiation damage and destruction of the nucleic acid function lethal microorganisms, so as to achieve the purpose of disinfection. Ultraviolet light can result in bond of nucleic acids and strand breaks, interstrand crosslinking and the formation of photochemical products, etc., thereby changing the biological activity of DNA, and microorganisms themselves can not replicate, such UV damage is lethal damage. Advantages of UV disinfection as follows: the introduction of impurities in the water is not, essentially the same physical and chemical properties of water; water chemical composition (eg content) and temperature changes do not affect the general disinfection; no additional increase in the water smell, taste, no such disinfection byproducts such as trihalomethanes class; a wide range of rapidly bactericidal, processing time is short, at a certain intensity of radiation is generally only ten seconds to kill pathogenic microorganisms, disinfection can kill some of the bacteria can not be inactivated , but also to a certain extent, some of the higher control and other aquatic organisms such as algae and red worms, etc; excessive treatment generally does not produce water quality issues; integrated device structure is simple, easy to install, compact and lightweight, the head loss is small, covering less; equipment operation easy to operate and manage, easy to automate the maintenance of a well-designed system rarely workload; operational management safer, basically no use, transport and storage of other chemicals may bring toxic, flammable, explosive and corrosive safety hazards; disinfection system in addition to the pump must run accident, no other noise sources.
