How to see if the swimming pool has been changed and why the swimming pool water has not been change

The quality of the pool's water is worrying, and although the pool claims to filter and disinfect the water every day, the water has not been changed for several years and has been in a semi-circular state. Secretions such as sweat from the human body cannot be completely eliminated by filtration and disinfectant.

Before swimming, look to see if the pool is crystal clear and free of sediment, and then you can smell it, a clean pool only has a slight smell of medicine, and an unhygienic pool may have a strong smell of urine and a pungent smell of medicine.

The water change in the swimming pool is very infrequent, only 3-4 times a year. Especially in heated swimming pools, the initial heating is very expensive. Therefore, the swimming pool is generally replenished according to the daily water replenishment, of course, the water replenishment is added before the heat exchange in the swimming pool machine room.

So you want to encounter a swimming pool water change, unless you are lucky, or someone says to you about the water change inside, otherwise you generally can't see that the water in the swimming pool is recycled. I am a professional in the construction and design of circulating water treatment system for constant temperature swimming pools.

In accordance with the "Hygienic Norms for Swimming Places.

Swimming pools must be replaced with new water every day, and the replacement rate is usually between 5% and 10%. However, some pools replace no more than 1% of the entire pool of water per week.

Long-term non-change of water and circulation system.

In order to keep the water clear, some swimming pools use polyaluminum chloride in large quantities and repeatedly.

Precipitant to adsorb suspended solids in water. It looks clear to the naked eye, but in fact, the water is rich in a large amount of aluminum ions, which can cause damage to the human body, especially the eyes.

The pool water in the swimming pool needs to be changed frequently, because in the pool, different people will use it every day, and the pool water will be slowly contaminated, although the pool filtration equipment and disinfection equipment can filter and disinfect the pool water. However, the pool water still needs to be replaced, so how often should the pool water be replaced?

Generally speaking, more formal and formal swimming pools generally use 24-hour circulating filtration, and will ensure that the water quality meets the standard through sedimentation, filtration, disinfection, heating and other treatment processes. Therefore, the swimming pool only needs to be replenished with new water every day, and it does not need to be completely changed every day.

At present, the situation of changing the water for swimming is also more worrying, and replacing the water of the entire swimming pool at once is not only costly, but also requires a lot of time, which will affect the normal operation of the swimming pool. As a result, many swimming pools are now opting for simpler and more efficient ways to save money. The pool water will be circulated and filtered for 24 hours, and at the same time, after the swimming pool is closed, the pool will be poured into the pool with a base precipitant to stand overnight, so that the impurities in the pool water will sink to the bottom, and the impurities at the bottom of the pool will be sucked away by the suction machine the next day.

According to the relevant regulations, the swimming pool needs to be replaced with new water every day, and the replacement ratio is usually 5% to 10%, if the pool does not change the water for a long time, only chlorine-containing precipitants are used to adsorb suspended solids in the water. Such pool water is easy to cause harm to the human body, especially the eyes of the code.

Legal analysis: The water in the swimming pool will have different methods in different places, but it is generally changed in a 24-hour cycle.

Dear, I'm glad to answer for you! The overflow pool of the swimming pool is not changing all the time. Swimming pool overflow pools are often designed as systems that recycle water, rather than changing water all the time.

Here's how the overflow basin works:1Water Recycling System:

Natatorium overflow pools maintain water quality through a complex water circulation system. This system includes pumps, filters, and chemical treatment equipment. 2.

Water Pump: The water pump pumps the water out of the overflow basin and filters it through a filter. This removes dirt, impurities, and microorganisms to keep the water clear and healthy.

3.Filters: Filters are typically constructed from sand, quartz sand, or other materials.

Its role is to capture and filter out solid particles, bacteria, and viruses in the water. 4.Chemical Treatment:

Swimming pool water needs to be chemically treated to maintain proper pH and disinfection. Common treatment agents include chlorine and other disinfectants, collapsing beams, and chemicals that regulate pH. 5.

Overflow system: When the water level of the overflow pool rises to a certain height, the excess water will be discharged through the overflow system and re-injected with clean water through the drainage pipe. In general, the overflow pool continuously recycles water during the operation of the swimming pool, and is filtered and chemically treated to maintain the water quality.

A full water change will only be considered if there is a serious problem with water quality or regular maintenance is required. 

There are no hard and fast rules! The general method of hydration is 5% to 10% of water replenishment every day, and it takes about 10 to 20 days to change the water in the whole pool.

A pool of water in a standard swimming pool is about 2,000 cubic meters, and the non-residential water ** is about 6 yuan per cubic meter, and the cost of a pool of water is about 10,000 yuan. The cost of replacing all the water in one pool is too high, and most swimming pools are reluctant to change all the water at one time, and they all use water replenishment. For example, a pool of water in the swimming pool of Shougang Basketball Center is about 400 cubic meters, about 30 cubic meters of water is replenished a day, and the whole pool of water is replaced for about 13 days.

At present, there is no hard and fast rule on the time for a complete water change in the swimming pool, but according to the current national standard, the water should be replenished regularly every day, and the general swimming pool is replenished with 5% to 10% of the total water volume every day.

It is the unspoken rule of the industry to increase the amount of chlorine powder for disinfection to ensure that the bacteria do not exceed the standard. In addition to the excessive residual chlorine, there is also excessive urea caused by perspiration and urination, and the only way to completely solve the water quality problem is to change the water.

The water in the pool is generally not changed every day, and it is not actually necessary. Generally, the swimming pool can be fully changed once every 3-5 days on a regular basis. If the water is changed daily 1 2-1 3 fk:

Failure to achieve the purpose of improving water quality. In order to make the water quality of the swimming pool meet the standard, in addition to filtration and purification treatment, it is also necessary to disinfect. In order to replenish the lost water, a part of the pool water should be replenished every day due to splashing, evaporation, and backwashing.

Experience shows. This make-up water cannot be used to improve water quality, as it is the same as in the case of a partial change of water in a fully swapped tank. Even if fresh water is replenished with once-polluted water, the effect cannot be improved when bacteria and viruses multiply rapidly.

Circulating filters are relatively easy to manage, for example, some sand filters have not deteriorated after 300,000 consecutive uses. However, for safety reasons, regardless of the type of filter, it is best to do a full water change during the summer swimming season.

There are few in the pool, and the water is usually changed once a week. This is because it is not easy to change the water in a large swimming pool, and when someone comes to swim during the day, they come to change the water at night or at night, which is to not affect the business. If the water is changed too frequently, the cost will rise, which will affect the customer's consumption, so under normal circumstances, the water is changed once a week.

The water in the swimming pool, the replacement time, generally according to the number of people in the pool, is one to two days to change the water, if there are many people, but also to speed up the frequency of water change.

The swimming pool treatment system is not the same in different places, some are changed every two or three hours, this is relatively conscientious, and some are changed every 24 hours, I have seen the kind of open-air swimming pool, it is quite dirty, after all, you can't change the water, it will mix with the rain on rainy days, plus some fallen leaves...

The water in the swimming pool is generally changed once a week, and in case of special circumstances, or the water quality is not good, the water change interval will also be shortened. Of course, it is necessary to do sterilization and detoxification every day, that is, to ensure that the water quality of the swimming pool meets the swimming standards.

The water in the swimming pool is generally changed once every one to two weeks, and now most swimming pools basically use 24-hour circulating filtration, disinfectant sterilization and other methods to ensure that the water quality meets the standard, and there is no need to completely change the water every day, only need to replenish the new water regularly, and the new water replenished is mainly the water lost every day, accounting for about 5% to 10%.

Generally, the water in the swimming pool is changed every 7 days. But now there are high-end swimming pools, it is circulating water, there is no need to change so diligently, he may regularly sprinkle some anti-inflammatory things into it, so he will change the water for a longer time, you are like the general public swimming pool of the public swimming pool, its water will grow a little, about 7 days, some even longer, even half a month, he added green gas to it, add some sterilization things, because you changed the piano, the water bill is high?

I think the water in the pool is usually changed once a week or two weeks, but it still depends on what the pool is, and if it is a very good swimming pool, it is not impossible to change it once a day.

How often does the pool water usually change? For the sake of people's health, the water in the swimming pool should be recycled, so that the water in the swimming pool can ensure the health of swimmers.

First of all, it depends on the grade of this swimming pool, if it is a particularly high-end swimming pool, then he generally changes it once a day, if it is some ordinary swimming pool, then he changes it once a week, and carries out daily sterilization.

How often does the pool water change?

This depends on the nature of the swimming pool and the management personnel, the private one may change it once every half a month or so if it wants to make a profit, of course, the conscientious business may also change it once a week, but some of the water with star impurities at the bottom will be released in the middle.

The public ones may change every three to five days, and they may not need to make a profit just to promote national fitness and meet the needs of swimmers.

So try to go to a public swimming pool

The swimming pool of Nanchong Haoya Oriental Hotel has not changed the water for a long time, and swimming in it has a great taste. Who is in charge of this issue?

First, there is something that looks like a sewer pipe in a deeper place, which can be drained, and then the water is refilled.

It is cleaner to go in the morning because there are fewer people.

Material] A swimming pool is a place where people can swim and where people can move or compete. Most swimming pools are built on the ground, and according to the water temperature, they can be divided into general swimming pools and heated swimming pools.

The swimming pool is. A swimming venue where you can move or compete. Most swimming pools are built on the ground, and according to the water temperature, they can be divided into general swimming pools and heated swimming pools. Swimming pool is a special place for swimming sports. There are two types: indoor and outdoor. Officially than that.

The competition pool is 50 meters long, at least 21 meters wide, and the water depth is more than one meter; Pools for swimming, diving and water polo combined, water depth meters; The depth of the pool with a 10-metre jumping platform should be 5 metres. Swimming pool water.

The temperature should be kept at 27-28 ° C. Filtration and disinfection equipment should be in place to keep the pool water clean.
