UV disinfection principle and introduction www.gyzwx.com 13833174989 differences in their biological effects UV, ultraviolet can be divided into UV-A (320-400nm), UV-B (275-320nm), UV-C (200-275nm ) and vacuum ultraviolet part. Water is actually part of the use of UV-C ultraviolet light, 260nm has been confirmed in the vicinity of the band is the most efficient UV disinfection. Guanyu ultraviolet disinfection optics, microbiology, mechanical, chemical, electronics, fluid dynamics and other comprehensive science as a whole. UV disinfection using a specially designed high efficiency, high strength and long life UV-C ultraviolet light intensity ultraviolet UV-C light water device generates occurred. When bacteria, viruses, etc. subject to certain doses of ultraviolet UV-C light (wavelength 253.7nm) irradiation. And structure of the cell DNA is damaged, cells can not be regenerated, so as to achieve water disinfection and purification. The wavelength of 185nm line can also break down organic molecules in water to produce hydrogen radicals and oxidation of organic molecules to carbon dioxide, to remove the TOC purposes. UV disinfection product advantages efficient sterilization: UV on bacteria, viruses, sterilization using generally one to two seconds to reach 99% -99.9% of the sterilization rate. Efficient sterilization broad spectrum: broad-spectrum ultraviolet sterilization is the highest, its almost all bacteria, viruses can efficiently kill. No secondary pollution: UV sterilization is not adding any chemicals, so it will not produce water and surrounding environment of secondary pollution, the water does not change any ingredients. Running safe, reliable: the traditional disinfection techniques such as use of chloride or ozone, the disinfectants themselves are highly toxic, flammable substances, and ultraviolet disinfection system there is no such security risks. The operation and maintenance costs low: a small area of ??ultraviolet disinfection equipment, structures requiring a simple and therefore less total investment, low running costs, in tonnes of water level, its cost is only chlorinated 1 . UV disinfection equipment features use high-efficiency UV-C (LL or LH) UV lamp selection of the world's leading high-strength low-pressure UV lamp, lamp life guarantee 8000-10000 hours. Selection of high transmittance, high purity quartz tube, ensuring more than 90% of ultraviolet rays through. Constant use advanced, high-intensity UV special ballast, to ensure that the entire system is running normally in complex situations. High quality stainless steel reactor (304 or 316), and the reactor wall for special polished to enhance the sterilization effect. ? UV disinfection technical parameters?
