There are many disinfection methods of water, which can be basically divided into physical disinfection and chemical disinfection. Physical disinfection methods include: heating water to boiling, ultraviolet disinfection, ultrasonic disinfection and so on. Chemical methods include chlorination disinfection and ozone disinfection. The most reliable water treatment method is the sterilization technology of ultraviolet sterilizer. Here, we will introduce the disinfection method of ultraviolet sterilizer for you.
Illuminated ultraviolet sterilizer integrates optics, microbiology, mechanics, chemistry, electronics, fluid mechanics and other comprehensive sciences. Strong ultraviolet rays generated by a specially designed high-efficiency, high-intensity and long-life ultraviolet generator irradiate water. When bacteria and viruses in water are irradiated by a certain dose of ultraviolet light (wavelength 253.7nm), their cell DNA and structure are destroyed, and cell regeneration cannot be carried out, thus disinfection and purification of water can be realized.
1. Generally, the sterilization rate of bacteria and viruses can reach 99%-99.9% in one to two seconds.
2. Ultraviolet sterilization has the highest broad spectrum and can kill almost all bacteria and viruses at one time.
3. Ultraviolet sterilization does not use any chemicals, so it will not cause secondary pollution to the water body and surrounding environment at all, and will not change any components in the water.
4. The equipment is easy to operate and manage, and can realize automation.
5. The traditional disinfection technology uses chloride or ozone for disinfection, and its disinfectant itself is highly toxic and flammable, so its safety performance is low. However, ultraviolet disinfection has no such potential safety hazard at all, and its operating cost is also low. Its cost is only 1/3 of chlorine disinfection.
In conventional water treatment, although most bacteria, pathogens and microorganisms have been removed, and their physical forms have basically met the requirements of drinking water quality, a certain number of bacteria and viruses still exist.
The ultraviolet sterilizer is used to continuously kill water, so that pathogenic bacteria and viruses that endanger human health have nowhere to escape, ensuring the hygiene and safety of drinking water.
Beijing Shuangyue Times Water Treatment Equipment Co., Ltd. adheres to the enterprise purpose of "professionalism, authority, honesty and enjoyment", and develops and produces ultraviolet sterilizers, ultraviolet sterilizers, water tank self-cleaning sterilizers and automatic cleaning ultraviolet sterilizers.
