Whether it is a public swimming pool or a private swimming pool, the water quality treatment of the swimming pool is an important part, and the selection of swimming pool water treatment equipment is also very important. Especially in swimming pools where infants and young children swim, poor water treatment in the swimming pools directly affects the health of infants. In the process of swimming pool water treatment, the disinfection of swimming pool water is a very important link. Therefore, the selection of swimming pool water disinfection methods and the selection of disinfection equipment require special attention.
UV disinfection method
Ultraviolet disinfection is a physical disinfection method. Ultraviolet disinfection equipment, ultraviolet sterilizers, etc. are used in sewage treatment, and have the advantages of broad-spectrum sterilization and no secondary pollution. Ultraviolet disinfection and sterilization are emerging products in the water treatment industry. Under the attention of everyone, ultraviolet disinfection has developed into a mature and reliable disinfection technology. It has been widely used in various fields at home and abroad,and has become the mainstream of replacing traditional chemical disinfection methods. One of the techniques.
The origin of ultraviolet disinfection technology originated in the 1960s. Humans began to apply ultraviolet disinfection technology to urban sewage treatment. This is because at that time people had realized that the use of residual chlorine generated in the chlorination disinfection process was harmful to fish in water bodies, etc. Biological toxicity, and chemical disinfection methods such as chlorine disinfection will produce carcinogenic, gene-inducing, and mutagenic by-products such as trihalomethanes. It has been found through practice that ultraviolet disinfection does not produce disinfection by-products in urban sewage treatment. After entering the 21st century, ultraviolet disinfection technology has been more popularized. Domestically, it is expected that a considerable part of sewage treatment plants with conditions will adopt ultraviolet disinfection in the future.
How to use ultraviolet light for disinfection
The ultraviolet disinfection used in water supply and drainage projects refers to UVC disinfection. In principle, ultraviolet disinfection technology is based on modern epidemic prevention, medicine and photodynamics, using specially designed high efficiency, high strength and long life Ultraviolet light in the UVC band irradiates the running water to directly kill various bacteria, parasites, viruses, algae and other pathogens in the water to achieve the purpose of disinfection. Ultraviolet disinfection is a physical method that does not need to add any substances to the water and has no side effects. This is where it is superior to chlorination disinfection. It is usually used in combination with other substances. Common joint processes include UV+H2O2, +H2O2+O3 etc., can achieve better disinfection effect.
Water Conditioner
Application of Ultraviolet Water Disinfection Technology
After years of research and practice, the disinfection technology mainly composed of ultraviolet rays has become an ideal choice for deep purification of water supply due to its good treatment effect. The application of ultraviolet disinfection to the disinfection of urban sewage secondary treatment water can meet the requirements of landscape and green water, and can also be applied to water treatment and disinfection in many fields such as swimming pools, hot springs SPA, landscape water, and aquaculture.
The sewage sterilized by ultraviolet rays can effectively realize the resource utilization of sewage, and it can be used to irrigate farmland, woodland and lawn, etc. which can avoid the damage of chemical disinfectants to plants; it can prevent microorganisms from adapting to chemical disinfectants and reproducing when used for groundwater recharge Caused by formation blockage. Ultraviolet disinfection will become one of the mainstream technologies to replace traditional chemical disinfection methods.
