Many people like to swim in public swimming pools in hot summer, but China has a large population. Many swimming pools will be full in summer. Is the pool clean in summer?
Before embracing everyone, the water in the swimming pool is generally treated at least three ways: coagulation, filtration and disinfection Coagulation is prepared for filtration. There are many small impurities in the swimming pool, sweat, grease, cosmetics and so on. Because of their small size, these small particles are basically "leaky fish" if they are filtered directly. Therefore, coagulant is usually used to make the small particles in the pool stick together to become larger particles, which is convenient to be filtered out.

The water of regular swimming pool must be treated through the above links. The state also has standards for swimming pool water. How do we judge whether the water is clean when we go to the swimming pool? How do we judge whether the water in the swimming pool is dry?
1. Make sure that you can see the drain at the bottom of the swimming pool with your eyes. For safety, make sure that the cover of the drain is firm to avoid accidental death caused by the drain sucking The pool water should be clear and transparent, at least the same as the tap water. First, see if there is dust and other debris visible to the naked eye on the water surface, then stand at the side of the pool and cross the water surface to see the fourth and fifth lane lines. If not, it means that the water quality is not good. Related article link: http://www.4hw.com.cn/life/jiankang.html
2. By sniffing this method, we can roughly judge whether the dosage of disinfectant is obviously over the standard. If there is a strong pungent smell after entering the swimming pool, that is, the smell of bleaching powder, it means that the disinfectant may be excessive.
3. If the pH value is available, the test paper can be used to detect the pH value. The pH value of the swimming pool should be 7.2-7.8.
How to swim "clean" in a public pool?
1. To select a regular swimming pool, it is necessary to select a standardized and more formal swimming venue. Only a regular venue can have standard filtration, disinfection and other measures, and the health situation is more guaranteed.
2. "Clean yourself" if you happen to have diarrhea or a wound, don't go swimming. You'd better take a shower before entering the swimming pool. It only takes one minute to get rid of the dust on you. It's good for you and him.
3. Don't swallow water. Don't urinate when swimming. Try not to swallow water (although it is inevitable sometimes, especially for novices), and don't urinate in the pool (although many people admit that they urinated in the pool).
4. After swimming, you must take a shower, and use bath fluid to wash away the unclean things, bacteria and viruses that cause upper body trouble during swimming In order to prevent water from entering your ears, you can wear earplugs for protection. If you still have water, you should lean your head to the side of the water, pull your ears back and up, tap them with your other hand or jump with one foot, and the water in your ears will flow out. Remember, when you jump, put on your shoes, find a dry, flat ground and jump again.
5. Be careful not to go swimming when there are many people in the swimming pool. The more people there are, the more potential sources of infection there are.
6. Don't use others' things and personal belongings to store independently, and don't share them with others at any time; don't use public bath towels, swimsuits, and don't sit around casually.
As long as the above points are achieved, you can swim safely, and your mother will not have to worry about the infectious diseases.
