Tianjin TLZX20-30B2 ultraviolet water purification device 8

UV disinfection Division Jingtao www.gyzwx.com 13833174989 an ultraviolet disinfection principle ?????? ultraviolet disinfection using a specially designed high efficiency, high strength and long life UV-C ultraviolet light intensity device generates occurred Ultraviolet UV-C irradiation water. 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. Second, Guan Yu UV disinfection has the following advantages returned 1, high efficiency sterilization: UV on bacteria, viruses, sterilization using generally one to two seconds to reach 99% -99.9% of the sterilization rate. ~ ~ ~ 2, efficient sterilization broad spectrum: broad-spectrum ultraviolet sterilization is the highest, its almost all bacteria, viruses can efficiently kill. ~ ~ ~ 3, no secondary pollution: ultraviolet sterilization is not adding any chemicals, so it will not produce secondary pollution of water bodies and the surrounding environment, the water does not change any ingredients. ~ ~ ~ 4, safe and 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. ~ ~ ~ 5, and operation and maintenance costs of the 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, and it costs only chlorine sterilized half. Third, Guan Yu UV disinfection disinfection equipment returned 1, ultraviolet disinfection efficiency of 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. ~ ~ ~ 2, ultraviolet disinfection selection of high transmittance, high purity quartz tube, ensuring more than 90% of ultraviolet rays through. ~ ~ ~ 3, ultraviolet disinfection constant use advanced, high-intensity UV special ballast, to ensure that the entire system is running normally in complex situations. 4, ultraviolet disinfection of high quality stainless steel reactor (304 or 316), and the reactor wall for special polished to enhance the sterilization effect. Fourth, the UV sterilizer on the inactivation of microorganisms in water Figure ~ ~ Table 1 UV technology for disinfection efficiency of common bacteria and viruses (ultraviolet radiation intensity 30mW / cm2) species?
