Question 2: Is the water in the swimming pool clean? Is it easy to get skin diseases? A swimming pool is unlikely to be infected with sexually transmitted diseases and skin diseases. Many people are most worried about: Will swimming in the swimming pool lead to sexually transmitted diseases and skin diseases? Some patients also asked if they were swimming after seeing a doctor because of skin discomfort. Professor Mao believes that although the possibility of infectious diseases and skin diseases in swimming pools cannot be completely ruled out, this possibility is very small and there is no need to worry too much. Professor Mao explained that because swimming pools are generally disinfected with disinfectants, it will be more difficult to spread some sexually transmitted diseases and skin diseases through fire secretions. Because it takes a certain time for patients' secretions to reach healthy people through water flow, in this process, most germs will be killed under the action of disinfectants, and the number and vitality of germs reaching healthy people are not much, so the chance of infection is not great. However, if the infected patients are close to the healthy people, and the bacteria reach the healthy people after a short contact with disinfectants in the swimming pool, they may be infected with sexually transmitted diseases and skin diseases. People with skin diseases should not go swimming. The swimming pool is a public place. Therefore, patients with gonorrhea, tinea pedis, folliculitis and other skin diseases should not go swimming in the swimming pool to prevent the spread of germs, and at the same time prevent other people's germs from aggravating their illness. Expert advice: don't go swimming to prevent your skin from being damaged by diseases in the swimming pool. Because most skin diseases are contact infections, if a healthy person's skin is damaged and soaked in water for a period of time, the cuticle of the skin will soften and easily attract foreign bodies. Swimming at this time will increase the risk of being infected by germs carried by other people in the pool or bacteria carried by the pool itself. You shouldn't stay in the swimming pool for too long. You should take a bath immediately after swimming. Swimming pools contain a lot of substances, including germs, bacteria and other people's secretions. Therefore, you must take a bath immediately after swimming and clean up the bacteria, germs and disinfectants left on your body to reduce the risk of skin diseases. Don't screen strong alkaline emulsion when cleaning, and don't rely too much on emulsion. Many people are used to using strong alkaline lotion after swimming in order to achieve disinfection effect. However, Professor Mao pointed out that during swimming, on the one hand, water will degrease the skin, on the other hand, chlorine-containing disinfectants in swimming pools will also have a boring effect on the skin. At this time, if you use strong alkaline emulsion products, it will cause harm to the skin, so try to choose mild emulsion or bath products. If you have eczema and dermatitis, stop using a slightly stronger emollient after cleaning. At the same time, Professor Mao suggested that although some lotions and toiletries can play a bactericidal role, they should never be used as disinfectants or drugs, let alone think that they are safe after washing. If the situation is not warm, seek medical advice in time.
Question 3: How to judge whether the swimming pool water is clean or not? How to judge whether swimming pool water is clean or not? There are several standards for clean swimming pool water:
With the arrival of summer, more and more people go swimming, and many people are worried about the water quality safety of the swimming pool around them. So how do you "see" whether the water quality of a swimming pool is up to standard? The quality of swimming pool water has a great relationship with the swimming pool water treatment system. Fu Rui swimming pool equipment teaches you a few tricks.
Look at this color.
If the residual chlorine content is normal and the water quality is excellent, the swimming pool water paved with white tiles will appear bright light blue. Some swimming pools use light blue tiles, which will show a dark blue effect. If the water is white and slightly turbid, it may be bacteria exceeding the standard.
It looks clear and turbid
The pool water with turbidity reaching the standard is crystal clear and can be easily seen 20 meters away from the pool. If there is no sediment at the bottom of the pool, the foam dissipation time of the pool water is within 15 seconds, which means that the pool water is often changed and relatively clean. When there are not many swimmers, you can't see15m in the water, which is generally unqualified.
smell
If you can smell the faint chlorine smell near the water surface, it is qualified; There is a strong medicinal smell, even choking may exceed the standard, or the site is not well ventilated; Water with bad smell and sewer smell is unqualified.
By feeling
People who often swim can feel the softness and hardness of water. Feeling soft means that the water quality is excellent, feeling hard and astringent, even itchy and painful, and the water quality may be poor.
If you are not sure whether the water quality of the swimming pool is up to standard, it is best to choose some swimming venues with good conditions. A good swimming pool will use relatively good swimming pool water treatment equipment.
Question 4: Is the swimming pool clean? Take 10 ml water sample and put it into the instrument, and it only takes 30 seconds to detect the turbidity of water quality on site. This is the first turbidity meter put into use by the Municipal Health Supervision Institute to detect the water quality of swimming pools. Yesterday, the staff of the Municipal Health Supervision Office visited a number of swimming pools such as Hucheng National Fitness Center and Huzhou Normal College. The test results show that the water quality of swimming pools in urban areas is generally good, but some swimming pools are not disinfected frequently and the health certificates of staff are expired.
Question 5: Is the water in the river cleaner for swimming or better for swimming pool? This river is rich in vitamins, minerals and some microorganisms that people need and don't need.
The swimming pool is mixed with various human fluids, such as urine, nasal fluid, saliva and some germs of potential diseases.
The point is: it's not what kind of food is clean, but what kind of food you want to drink.
This is the standard answer!
Question 6: Is the water in the swimming pool clean? The standard swimming pool is equipped with a complete water circulation treatment system, which ensures the water quality to meet the standard through the treatment processes such as sedimentation, filtration, disinfection and heating. It is difficult for viruses and bacteria to survive in qualified pool water.
Question 7: Is the water in the swimming pool clean? First of all, the water quality of the swimming pool is observed by the naked eye. See if there are a lot of floating dust or suspended particles in the water. Secondly, ask the relevant swimming pool personnel about the disinfection status of the pool water. Finally, according to your own conditions, check the water quality if possible. Swimming pools have water quality standards. Ph 6.8 - 7.2。 If disinfected with chlorine, oto 1.5g/m3.
Question 8: How to keep the water quality of outdoor swimming pool clean? Swimming pool water should be disinfected with chlorine-containing disinfectant. At present, chlorine-containing disinfectants used in swimming pools in China include liquid chlorine, bleaching powder, bleaching water and TCCA. Bleaching powder is gradually eliminated because of its residue, blocking pipelines and affecting water quality. Chlorine in bleaching water is extremely unstable, and its available chlorine will gradually decrease with the influence of environment, temperature, humidity, light and storage time. When liquid chlorine is used for disinfection, measures should be taken to prevent leakage, including that the water treatment room should be far away from the swimming pool and closed, and there should be an emergency alarm device in the room. Liquid chlorine should be automatically added in vacuum, and a device should be set to make chlorine fully mixed and contacted with pool water; Because TCCA has a * * * yoke group, hypochlorous acid is gradually released in water, and the cyanurate left behind has a stabilizing effect on available chlorine in water. It is non-toxic and quite stable when stored. In recent years, a considerable number of swimming pools in China use TCCA as a disinfectant for swimming pool water.
Under conditions and needs, ozone, ultraviolet or other disinfection methods can be used. When ozone or ultraviolet disinfection is used, chlorine disinfection should be supplemented to maintain the continuity of disinfection.
The chlorine dosage of swimming pool water (including fresh water continuously supplied by children's shallow pool) is calculated and determined according to the free residual chlorine content of pool water of 0.3-0.5mg/L, and that of foot bath disinfection pool water is calculated and determined according to the free residual chlorine content of pool water of 5- 10mg/L, and the best dosing time is 65438+ 0-2 hours before opening the bottle. When the swimming pool is open, the residual chlorine in the swimming pool water should be measured regularly and recorded. Conditional, when the indoor swimming place is open, measure the residual chlorine every 2 hours; When the outdoor swimming place is open, measure the residual chlorine every hour.
Question 9: Is the water in the swimming pool clean? The water in the swimming pool is unclean. According to the survey, the water in general swimming pools contains 40% urea, which shows that the sanitary level is low. If you are in poor health, you'd better not go, because bacteria are the easiest to invade.
Question 10: How to clean the swimming pool water urgently? If you decide to run the swimming pool for a long time and are willing to invest appropriately, I still suggest you try to suck water directly from the swimming pool with a circulating pump. In principle, it is similar to the practice of raising fish in a fish tank, except that the power of the "circulating pump" is amplified. Its working principle is as follows: firstly, hair fibers and large particles are removed by the hair collector, then coagulant is added by the dosing device, and after being stirred and mixed by the impeller of the pump, it enters the quartz sand filter to remove suspended substances, and the filtered water is disinfected to make it meet the national swimming pool water quality standard, and then sent back to the swimming pool for reuse. This is the recycling process of swimming pool water purification. Filter is the main equipment in the circulating water treatment system of swimming pool. This kind of filter has a unique internal structure, and the filter material used is homogeneous quartz sand, which has high strength and long service life. Large amount of treated water and good filtering effect. The equipment has long running cycle and simple operation. This practice may require appropriate renovation of the swimming pool, with a certain amount of investment in the early stage, which is obviously not cost-effective for temporary rental operation; If it is a small and medium-sized indoor swimming pool with no seasonal differences throughout the year, this working principle can prolong the period of comprehensive water change, and the visual quality of water is obviously better than that of simple dosing and disinfection.
