PDC-300 UV disinfection equipment 9

First, UV disinfection disinfection principle http://www.gyzwx.com 13833174989 ultraviolet disinfection their differences in the biological effects of ultraviolet can be divided into UV-A (320-400nm), UV-B (275-320nm), UV-C (200-275nm) and vacuum ultraviolet part. Water treatment is the use of ultraviolet UV-C part, 260nm has been confirmed in the vicinity of the band is the most efficient UV disinfection. This equipment optics, microbiology, mechanical, chemical, electronics, fluid dynamics and other comprehensive science as a whole. Using a specially designed high efficiency, high strength and long life UV-C ultraviolet light intensity of ultraviolet UV-C light water generating means occur. When bacteria, viruses, etc. are subject to certain dose of ultraviolet UV-C light (wavelength 253.7nm) radiation. And the 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 in water to achieve the purpose of removal of TOC. Second, UV disinfection has the following advantages: 1, the second high-efficiency equipment sterilization: UV on bacteria, viruses, sterilization using generally one to two seconds to reach 99% -99.9% of the sterilization rate. 2, the device efficient sterilization broad spectrum: broad-spectrum ultraviolet sterilization is the highest, its almost all bacteria, viruses can efficiently kill. 3, no secondary pollution: UV disinfection does not add any chemicals, so it will not produce secondary pollution of water bodies and the surrounding environment. Does not change any ingredients. 4, the equipment running safe, reliable: the traditional disinfection techniques such as use of chloride or ozone, the disinfectants themselves are highly toxic, flammable substances. The UV disinfection system there is no such security risks. 5, the equipment 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, its cost is only chlorinated 1. Third, the UV sterilizer maintenance, service: 1, ultraviolet sterilizer regular checks to ensure the normal operation of the UV lamp. Note: UV lamp should be continued in the open state, repeatedly switch will seriously affect the lamp life. 2, UV sterilizer regular cleaning: according to water quality, UV lamp and quartz glass tube require regular cleaning. Note: The alcohol cotton ball or gauze wipe the lamp, remove the quartz glass tube and wipe the dirt, so as not to affect the UV transmittance, and the impact bactericidal effect. 3, UV sterilizer lamp replacement: imported lamp 9000 hours of continuous use, or after a year, you should replace the UV lamp, in order to ensure a high rate of sterilization. When replacing the lamp, first unplug the lamp power, out of the tube, and then wipe the new lamp carefully inserted into the sterilizer, installed seals, check for leaking, then plug in the power supply. Note: Do not use your fingers touch the new lamp quartz glass, otherwise it will affect the bactericidal effect due to stains. 4, ultraviolet disinfection prevent ultraviolet radiation: ultraviolet radiation on bacteria have a strong lethal to humans also have some damage, boot light disinfection, should avoid direct exposure to the human body, if necessary, use protective glasses, not directly with your eyes face the light source, in order to avoid burns Mask. Fourth, UV disinfection installation, commissioning: 1, ultraviolet disinfection should be installed horizontally (prohibited vertical installation). 2, ultraviolet disinfection cylinder shall withstand external pressure. 3, ultraviolet disinfection should be installed at the outlet of the tank or water tower, Flow volume, high pressure or long pipe network while installed on close to the user's trunk (branch) is better. 4, extending from both ends of the ultraviolet disinfection outward, should be left ≥1 m ≥0.4 m space, in order to replace the lamp, should remain 0.6 meters of unobstructed space front control panel for easy maintenance. 5, regardless of the choice of one or more UV disinfection in parallel, shall install a bypass pipe and valve for easy maintenance. 6, should be a reasonable choice of installation location, pay attention to the electronic control part of waterproof, moisture-proof. 7, should voltage, power options power outlet or power strip nameplate wire connection. 8, quartz glass tube and the UV lamp is a valuable fragile, transportation, installation, use should be avoided bump.
