Swimming pool water disinfection methods include traditional chlorine disinfection, ozone disinfection, copper and silver ion disinfection.
1. Traditional chlorine disinfection
The outstanding advantages of liquid chlorine disinfection are the continuous disinfection of residual chlorine, low price, simple operation, and no need for huge equipment. However, chlorine itself is poisonous, and attention must be paid to safety when using it to prevent leakage. And water often produces a variety of harmful substances after chlorine disinfection, especially disinfection by-products with "three-in-one" effect, such as chloroform and chloroacetic acid. In addition, liquid chlorine cannot effectively kill Cryptosporidium and its cysts. Therefore, chlorine disinfection is gradually being replaced by other disinfection methods.
2. Ozone disinfection
Divided into partial flow ozone dosing system and full flow ozone dosing system
2.1 Split flow ozone dosing system
The divided flow of ozone disinfection should be 25% of the circulating water flow. For newly built swimming pools and water amusement pools with a general population load and relatively stable personnel, a split-flow ozone disinfection system can be used, or when an ozone disinfection system is added to an existing swimming pool, a split-flow ozone disinfection system can be used.
2.2 Full flow ozone dosing system
World-class and national-level competition swimming pools and swimming pools and water amusement pools with high requirements for water sanitation and high number of people should use a full-flow ozone disinfection system in which circulating water filtration and residual ozone adsorption and filtration are set separately for disinfection; For swimming pools and water amusement pools with high load and high requirements on pool water sanitation, it is advisable to use a full-flow ozone disinfection system that combines circulating water filtration and residual ozone adsorption filtration to disinfect all circulating water.
3. Copper and silver ion disinfection
At present, copper and silver ion technology is widely used in developed countries such as the United States and the United Kingdom. Copper and silver ion disinfection has become a mature technology. The combined use of disinfectants has the best effect, especially in the test of drinking water, and the concentration is lower than the drinking standard to obtain good results, so this technology has been used in drinking water and circulating cooling water projects. Heavy use. Copper and silver ion disinfection has the following advantages: no toxic by-products, no secondary pollution; colorless, odorless, strong chemical stability; not affected by temperature, can maintain the sterilization effect for a long time; no need for special management, maintenance-free.
