The application of swimming pool ultraviolet disinfectors is aimed at the continuous improvement of public requirements for pool water quality, the control of trihalomethanes (THMs) content by regulations, and the desire of many pool equipment operators to reduce the use of chlorine agents. The application of ultraviolet disinfection equipment in swimming pools can ensure the water quality of swimming pools. Reduce residual chlorine: The chlorine content in the pool water is reduced, reducing disinfection by-products and making the pool environment healthier.
Reduce the dosage of chlorine: When chlorine reacts with organic compounds on swimmers, disinfection by-products such as chloramines are produced. These by-products are the root cause of discomfort in people's eyes and respiratory organs. Chloramine is corrosive and can corrode pool walls and water pipes. By exposing the fully circulating water flow to ultraviolet radiation, the ultraviolet lamp can reduce the amount of chlorine used to within the required range.
Reduce trihalomethanes: In pool water disinfected with chlorine, one of the disinfection by-products is trihalomethanes (THMs). The most common is methane, which is a suspected carcinogen. The use of a swimming pool ultraviolet sterilizer in conjunction with reducing chlorine dosage has reduced the methane content in the pool water. Killing microorganisms: Another benefit of using ultraviolet technology to purify pool water is the ability to * inactivate chlorine resistant microbial tissues, such as Legionella pneumophila, Escherichia coli, Pseudomonas aeruginosa, Cryptosporidium, Amoeba, and so on. Ultraviolet radiation achieves inactivation by damaging the DNA and DNA repair enzymes of these microorganisms.
Killing Legionella in swimming pools and shower pools: Legionella is a highly dangerous pathogenic microorganism that appears in swimming pools and warm water circulating shower pools. It can resist residual chlorine, but it will be killed by ultraviolet light. Temperature does not affect the effect of ultraviolet light, so swimming pool ultraviolet disinfectors are suitable for warm water baths and other swimming pools.
The application and research of ultraviolet disinfectors in water treatment can be divided into two units: drinking water ultraviolet disinfectors and sewage ultraviolet disinfectors. In recent years, both international and domestic research has focused on the disinfection mechanism, process design, light source characteristics, system maintenance, and other aspects of ultraviolet disinfection.
The application and research of ultraviolet disinfection equipment for drinking water should be based on the actual situation of water sources in China, and develop ultraviolet disinfection technology suitable for China's water sources. The combination of ultraviolet and chloramine disinfection methods has obvious advantages in the field of water supply, not only with good disinfection effect but also to ensure the stability of water quality in the pipeline network. The Tianjin Teda tap water ultraviolet disinfection project, as the first domestic demonstration project for drinking water ultraviolet disinfection designed and put into operation simultaneously with water purification technology, has been in operation for 3 years. Some experts and scholars have conducted in-depth research and summary on the application of Tianjin Teda ultraviolet disinfection project.
