1. Efficient broad-spectrum sterilization: Ultraviolet UVC technology has high sterilization broad-spectrum among all current sterilization technologies. It is against almost all bacteria,
Viruses can be killed efficiently. And for some parasites that are extremely harmful to humans and can not be effectively killed by chlorine or even ozone (such as cryptosporidium, giardia giardia, etc.).
2. High-efficiency sterilization: Ultraviolet UVC sterilization technology has the sterilization efficiency unmatched by other technologies. The sterilization efficiency can reach 99% to 99.9%. Table 1 lists
The sterilization time of UV-C technology for several common bacteria and viruses generally only takes less than 1 second. Traditional chemical disinfection methods such as chlorine and ozone generally take 20 minutes to 1 hour to achieve the sterilization effect of ultraviolet uvC.
3. No secondary pollution: Since the UVC technology can be controlled to only sterilize, and does not add any chemical agents, it will not affect the water body and surroundings
The environment produces secondary pollution. Does not change any components in the water. For chlorine disinfection, the organochlorine produced by it and the organic matter in the water has been recognized as carcinogenic to the human body, and the chlorine compounds contained in the water will have a counterproductive effect on some occasions and cause toxicity to aquatic organisms and the water environment. The ozone method has similar problems. A large amount of unpleasant ozone that is not dissolved in the water volatilizes into the air, which is harmful to the physical and mental health of nearby staff.
4. Safe and reliable operation: The traditional disinfection technology such as the use of chloride or ozone, the disinfectant itself is a highly toxic, flammable, and explosive substance.
The use of these substances poses a potential threat to the safety of operation site personnel, the surrounding environment and residents, and special care is required. my country's public security, fire protection and environmental protection departments have strict transportation, storage and operation regulations on the use of these high-risk substances. These have greatly increased the psychological burden and insecurity of the leaders, operators and surrounding residents of the grassroots units. Modern UV disinfection systems do not have such hidden safety hazards, and are a much safer and more reliable disinfection technology for the surrounding environment and operators.
5. Low operating and maintenance costs: Usually a high-efficiency technology is always associated with high costs and high operating costs. However, ultraviolet UVC technology
Is the exception. Due to the improvement of the core Uvc technology in the 1990s, the ultraviolet Uvc disinfection technology not only has the highest disinfection efficiency among all disinfection methods, but also has simple disinfection operation and maintenance, and low operating costs. The processing capacity of 1,000 tons can reach 4% per ton of water. Lower, therefore, its cost performance is high among all disinfection technologies. It not only has the high efficiency that other disinfection technologies cannot match, but also has the advantages of low cost and operating cost. At the level of thousands of tons of water treatment, its cost is only 1/2 of chlorine disinfection, 2/5 of chlorine plus dechlorination disinfection, and only 1/9 of the cost of ozone disinfection. Even at the level of 100,000 tons of processing capacity, the investment and operating costs of uvc are far lower than other disinfection technologies.
6. Easy to install and operate: The ultraviolet UVc disinfection system is modular in design, easy to install, suitable for any installation site conditions, and does not damage the site
Equipment, pipelines and building structures. The system only needs to be connected to the power supply, and it can run continuously 24 hours a day, 365 days a year. There is no need to stop when cleaning the lamp. It can be used uninterrupted except for the regular maintenance of 1-2 hours. Chlorine and ozone disinfection operations are complex and require high quality of operators. Any negligence may reduce the disinfection effect and even cause serious accidents.
