In the hot summer, many citizens will choose to go to the swimming pool or beach to cool off.
However, accidents often occur in crowded places. Recently, the Metro Vancouver Health Bureau issued a warning: A public swimming pool in New Westminster, ten kilometers away from Vancouver, has reported measles patients.

The Department of Health stated that citizens who have been to the Moody Park outdoor swimming pool in New Westminster from 1:30 to 4:30 pm on August 19, 2018 may be infected with measles and need to be quarantined immediately.

The measles virus is highly contagious and can spread rapidly through the air, droplets, or through contact with contaminated supplies.
With the spread of the epidemic, it has spread to many parts of the country. Under the influence of this epidemic, people have also paid unprecedented attention to disinfection. Can operators of swimming pool venues despise pool water disinfection?
Swimming pool pollution mainly comes from the bacteria, dander, skin secretion of sweat, hair loss, etc. carried by swimmers, especially when swimmers do not pay attention to the shower before swimming, the pollution is more serious. The by-products and residues of chemicals can also cause pollution. If they are not removed, they will spread to swimmers a variety of infectious diseases such as eyes, nose, ears, throat, gastrointestinal tract, skin, and reproductive system.
Common bacteria and viruses in swimming pools: Neisseria gonorrhoeae (easy to cause gonorrhea), Treponema pallidum (easy to cause syphilis), human papillomavirus (easy to cause condyloma acuminatum), Shigella (easy to cause diarrhea), Legionella (easy to Cause pneumonia), Escherichia coli, etc., but they cannot survive in a sterile environment.
In addition, there are some parts that cannot be directly killed by chlorine disinfectants, such as: Pseudomonas aeruginosa-Pseudomonas aeruginosa, which can cause inflammation and abscesses. When faced with these bacteria, viruses and microorganisms, our disinfection measures cannot Stay on a single chlorine pill, chlorine tablet disinfection method, the current commonly used disinfection methods include ozone disinfection, ultraviolet disinfection and so on.
Ultraviolet sterilization is mainly through ultraviolet light irradiated by bacteria and viruses, the ultraviolet spectrum ability is absorbed by the cell nucleus, so that the nucleic acid structure is destroyed, so that various bacteria and viruses lose their ability to replicate and multiply, and eventually die and achieve the sterilization effect.
While killing bacteria, chlorine will form chloramines and trihalomethanes with organic matter (such as urea) in the water. The high volatility of chloramine can cause irritation to human eyes, ears, nose, etc., and even induce tuberculosis. It can also cause severe corrosion to the steel structure of the swimming pool. Ultraviolet technology can effectively decompose the concentration of chloramine in the water while disinfecting and sterilizing, and control the concentration of chloramine below the safe range.
Ultraviolet disinfection is a purely physical disinfection method with high sterilization efficiency. The sterilization of bacteria and viruses can generally achieve a sterilization rate of 99%-99.9% in one to two seconds. The bactericidal has a high broad spectrum, and it can effectively remove the microorganisms Cryptosporidium, Giardia, and non-tuberculous mycobacteria that cannot be killed by chlorine. The pool water that has been disinfected by ultraviolet rays has no chemical residues, no corrosiveness, no toxic side effects, and no harm to human skin and body health.
The sanitation and safety of swimmers cannot be ignored. When choosing an appropriate disinfection method, the owner should also design a mandatory shower and a mandatory foot bath, so as to better prevent the occurrence of diseases and ensure the safety of swimmers.
