I. Changsha, Hunan ultraviolet disinfection biological principles of their biological differences, 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, in the band 253.7nm the world's leading high-strength low-pressure UV lamp has been proven to be near the most efficient UV disinfection. When the water microorganisms subjected to high intensity UV light, microbial DNA, RNA destruction of the internal structure, can not be copied, so that without the use of any chemical substances in the case to achieve sterilization, disinfection effect; other hand, the ultraviolet irradiation caused by free radicals can be generated under photoionization, causing micro-organisms can not copy propagation, it will die a natural death or destroy the human immune system will not cause harm to humans, so as to achieve the purpose of disinfection. Two. Ultraviolet disinfection disinfection methods comparison with other disinfection methods disinfection time disinfection byproducts cost effectiveness security chlorine> 30min trihalomethanes, haloacetic acids, halogenated nitrile infrastructure, low operation cost effective sterilization chlorine toxic, corrosive , operation and management of certain dangerous chloramines> 30min haloacetic acids, chlorinated nitrile, nitrile bromide infrastructure, lower operating costs sterilization effect is poor, sterilizing effect of persistent corrosive chlorine dioxide pipeline network 10 ~ 20min Asia perchlorate, chlorate high capital and installation costs, lower operating costs sterilization effect is better than chlorine chlorine dioxide is unstable, strong oxidizing, toxic and corrosive, operation and management requirements of high ozone 5 ~ 10min bromate , aldehydes, ketones, carboxylic acids, nitriles dibromoacetone large infrastructure investments, operating costs are high sterilization and virucidal effects are good, no sustained bactericidal ability toxic, strong oxidation resistance, high UV operational management requirements 5 ~ 10s no installation fee of 50% of the chlorine dioxide; operating costs for the 25% of chloramine disinfection effect is good, fast, no sustained bactericidal good safety three. Changsha water UV disinfection applications advantages (1) Ultraviolet disinfection sterilization technology with high efficiency, safe and reliable operation, secondary pollution. (2) of Cryptosporidium and Giardia have effects disinfection effect, the conventional chlorine disinfection process on Cryptosporidium and Giardia inactivation low and at high chlorine dosage will produce a large amount of disinfection byproducts, and ultraviolet disinfection at lower UV doses of Cryptosporidium and Giardia inactivation can achieve higher results. (3) does not produce toxic byproducts, does not change the characteristics of organic matter, and because they do not dosing chemicals, does not produce harmful byproducts, and will not increase the AOC and BDOC and other damage biological stability of the water pipe network by-products. (4) to reduce odor and degradation of trace organics, trace organics in water by UV degradation has a certain ability, and can reduce water smell and taste. (5) small footprint, easy maintenance, and low cost. For every 50,000 tons of sewage disinfection with chlorine, the need to build a 130 meters long, 3 meters wide contacts sewers. The use of ultraviolet disinfection is only 20 meters long 3 meters wide area; ultraviolet disinfection operation and maintenance is simple, low operating costs, up only 4% yuan per ton of water or less, the cost performance has a great advantage. (6) disinfection by temperature, pH little effect.

Five, Changsha, Hunan ultraviolet disinfection equipment features 304 or 316 polished stainless steel; quartz tube to ensure optimal operating temperature; high output, hard glass UV lamps used in order to achieve maximum effectiveness; ultraviolet line detector, using the latest research in Germany All stainless steel shell with high-tech products anodized anti-rust treatment; · Adopt thermistor control panels and reaction apparatus; tired when using electronic instruments; equipment clean, electroplating polishing, cleaning up the environment for high; equipment electrician configuration applies to all over the world market; ultraviolet disinfection sterilization is mainly because of the effect is very good, but does not produce any side effects, there is the low cost. It is particularly easy to be accepted by users. UV disinfection is mainly composed of the following parts: the UV lamp, quartz tube, ballast, seals, tanks, water outlet, seals, insurance, plug, outfall, and other components. If the customer requires equipment can be added UV intensity detector, when tired, and so on. UV sterilizer stainless steel cylinder inside a quartz tube, inside the casing for the UV lamp, the sterilization process: water from entering the inlet flows through the device between the cylinder and the sleeve, after ultraviolet light irradiation sterilization, out from the outlet . Instantaneous water can kill bacteria, viruses, micro-organisms. VI. Changsha, Hunan ultraviolet disinfection equipment maintenance and repair (1) regular inspections to ensure the normal operation of the UV lamp. (2) Zhengzhou, Changsha, Hunan ultraviolet disinfection 12,000 hours of continuous use or a year, you should replace the UV lamp, in order to ensure a high rate of sterilization. Please pay particular attention should be continued in the open ultraviolet state, due to repeated opening and closing will seriously affect the useful life of the lamp. (3) Replacement UV lamp, first unplug the lamp power, take out the UV lamp. Replace with a new lamp, be careful not to touch the new lamp with your fingers quartz glass, because dirt will affect the germicidal lights, while carefully germicidal lamp in stainless steel inside.
