However, it is suggested that there are more sediments when it turns white.
It's best to sprinkle special precipitation medicine+bleaching powder ... and then you will see that after overnight precipitation, there is a layer of sediment at the bottom of the pool. Then you can draw the bottom floor (using professional pool vacuuming tools). Then you can inject a little water/
The average swimming pool is like this. Even swimming pools with automatic circulation systems sometimes use this method. The effect is best!
How to deal with the turbidity of swimming pool water? At present, the main product of water purifying agent (clarifier) used for swimming pool clarification in China is polyaluminum chloride, which is used when the swimming pool still cannot achieve good clarification effect after circulating filtration. Putting it in the swimming pool can sterilize and deodorize while purifying water.
The water in the swimming pool is white. What should I do? More copper sulfate and less bleaching powder will turn the water blue.
How to deal with the water quality problem of swimming pool? One is precipitation and clarification.
The second is disinfection and sterilization.
Use polyaluminum chloride or polyaluminum chloride or their mixture for precipitation clarification. Dissolve the coagulant in the mother liquor first, then sprinkle it in, stir it properly (just hang something with a floating rope and pull it a few times), then clarify it for a few hours, and then suck up the sediment at the bottom with a submersible pump.
Sodium hypochlorite or chlorine dioxide is used for disinfection and sterilization. Now there is a special pool disinfectant, and the proportion will be indicated for you. Sprinkle it in, stir it and let it stand for a while.
How to deal with the turbidity of outdoor swimming pool water treatment device/swimming pool water? Where are you from? If you want to get good water quality, you must do efficient precipitation filtration.
How to deal with the water quality of the infant swimming pool Although there is no clear regulation on the water quality of the infant swimming pool at present, the water quality of the infant swimming pool is higher than that of the adult swimming pool. At present, the state requires the water quality of children's swimming pools to be circulated once every 1-2 hours. This cycle does not mean that all new water needs to be replaced. All the water in the swimming pool must be filtered once.
The water quality of the infant swimming pool needs a high-precision filtration device, reversible diatomite filter, which can filter out Escherichia coli, protozoa, Giardia and so on. In the water, let the water clean naturally, and then add ultraviolet rays for disinfection to ensure the baby's health!
How to deal with the turbidity of swimming pool water (1) First, introduce the types and names of chemicals used in swimming pools.
1. Disinfectant-chlorine is mainly used for disinfection. At present, the disinfectants used in China mainly include bleaching powder, sodium hypochlorite, liquid chlorine, chlorine-containing disinfectant (TCCA), trichloroisocyanuric acid, bromochlorine and so on.
2. Precipitating coagulants-mainly divided into alkaline coagulants and acidic coagulants. At present, coagulants used in China are: aluminum chloride, alum, aluminum sulfate and so on.
3. Drugs for adjusting pH-mainly drugs with high alkalinity and drugs with neutral alkalinity. There are mainly several kinds: limestone (alkaline), hydrochloric acid (acidic) and carding (PH neutral).
(2) Briefly introduce the colors and delivery effects of some commonly used drugs mentioned above.
A, disinfectant
1, bleaching powder-white powder, the main component is compound calcium salt, and the effective component is calcium hypochlorite (OCL). When dissolved in water, it produces calcium oxide precipitate and hydrochloric acid, which produces new ecological oxygen for sterilization, with strong bactericidal power. Disadvantages are inconvenient storage and transportation, and there is residue in the pool water. 1000M3 water consumption is about 20-30kg bleaching powder.
2. Sodium hypochlorite (bleach)-The liquid is yellow and contains 65,438+00-65,438+05% of available oxygen. When dissolved in water, hypochlorous acid (HOCL) is produced, which is chlorinated with strong locusts under the action of light to produce a new ecological sterilization with strong bactericidal ability. Its advantages are convenient use, no residue in pool water and lasting effect. Disadvantages are inconvenient storage and transportation and high cost. 1000M3 water consumption is about 40-50kg.
3. Chlorine-containing disinfectants are divided into powder and flake, almost all of which exist in water in the form of sodium hypochlorite. They are neutral molecules, which can spread to the surface of negatively charged bacteria and enter the interior of bacteria through the cell membrane, resulting in the destruction of the fragile system of bacteria under chlorination. Finally, the bacteria died. Its advantages are convenient storage, transportation, storage and use, good sterilization effect and high available chlorine content. The disadvantage is that the water quality is unclear and the precipitation bleaching effect is poor. The dosage is 1000M3, 2.2-2.5kg, but the first dosage is three days, and it is put every other day after two days, and the powder is doubled for the first time, and then it is put once a day.
B, coagulant:
1, polyaluminum chloride-grayish yellow (powder), transparent (liquid), polyaluminum chloride is actually a kind of aluminum oxide, because it is a mixture of aluminum chloride, and its precipitation is mainly aluminum hydroxide AL(OH)2 precipitation, which is a micelle, which can wrap impurities in water or attach to its surface, and the more it accumulates, the more it precipitates, making the water clear. Its dosage is liquid 1000M3 water and solid 8- 10kg.
Alum is a white solid. Alum actually belongs to aluminum coagulant, and its PH value is acidic. The action principle of alum in water is the same as that of aluminum chloride, and the dosage is about 20-25 kg/1000M3 of water.
C. drugs for adjusting PH value
1, hydrochloric acid-hydrochloric acid is acidic in nature. Generally, when the PH value of the measured water is as high as 8.2, a proper amount of hydrochloric acid can be put in, and the dosage depends on the actual test. Experimental example: PH =8.2, 5- 10 kg/ 1000M3 water, and PH is basically 7.6-7.8, returning to the best status quo. (Hydrochloric acid has strong corrosiveness, so it should be diluted evenly in a small barrel in dosing pump and automatically dosed. )
2. carding-the PH value of carding is relatively neutral and generally high. If it is low, you can also put a proper amount of carding medicine to adjust the PH value to normal, and the dose is also obtained according to the actual test. (1000M3 of water can be put into 10- 15kg of carding powder).
Algae remover
Copper sulfate-blue in color, small in taste and smelly. Usually the dosage is 1000M3 water 0.5- 1kg, but it should not be used too frequently. Just play it once a month normally.
(3) Frequency, dosage, sequence and operation flow of fresh water treatment for the above four drugs:
1. Disinfectant: When using bleach for disinfection, when the swimming pool is in normal operation, bleach is put in once a day, and the dosage is 40-50kg per 1000M3 of water. The way to put bleach can be to add automatic bleach dosing pump after sunset, or to sprinkle it in underground water (when no one is swimming). There are many people swimming in summer, so it should be put in the morning and evening.
2. Coagulant: When using polyaluminum chloride to purify water, you can refer to the turbidity standard of water quality (no more than 5 degrees or standing on a 25M-wide bank, you can clearly see lanes 4 and 5 with a depth of 2.5M at the bottom of the pool). If it does not meet this standard, polyaluminum chloride should be put. The dosage is 8- 1000 kg polyaluminum chloride per 1000M3 of water. The dosing method can be as follows: after the sun goes down, the polyaluminum chloride is diluted, automatically dosed with an automatic dosing pump, or evenly splashed on the water surface. It is best to stir the water for 30 minutes, and pay attention to the PH value of the water when using it. This method can first determine whether the PH value of water is normal. If the PH value of water is too low, first put it into a neutralizing medicine comb, the comb weight is 10- 15 kg, which is about 1000M3 of water.
3. Algicidal agent: copper sulfate is used, and the dosage is 0.5- 1 kg per 1000M3 of water. Note: Don't play it too many times. You can only play the flash once a month. (or use it when finding moss. )
4. Summary: After introducing the chemical drugs commonly used in swimming pool water quality, the general situation of drug use is briefly summarized.
(1) In swimming pools that are often open, disinfectant should be put on cloudy days or after sunset every day, and the dosage of bleach is 40-50kg per 1000M3 of water. When there are no guests swimming in spring, you can use disinfectant every other day, and the dosage can be slightly reduced, but you should pay attention to the appearance of moss. It is best to put copper sulfate once every two months, with the weight of 0.5- 1 kg copper sulfate 1000M3 water.
(2) In a normally open swimming pool, attention should be paid to the maintenance of relevant equipment in the pump room and the operation process of handover equipment, and all equipment in the swimming pool and pump room should be regularly checked.
(3) Water quality, PH value and residual chlorine should be tested several times a day. The standard residual chlorine of water quality (bound state = 1- 1.5, free state =0.3-0.5) is normal, and the most normal is PH value =7.6-8.0. However, the situation of residual chlorine is unstable. Different water temperatures and different weather have different indicators. The residual chlorine value is the highest in the morning and evening, reaching above 1.0, and the lowest at noon is around 0.2, which is normal.
Usually add some blue alum, it will become clear, which is why most of the pool water looks blue!
How to deal with the poor water quality of swimming pool? Circulating water treatment
Swimming pool water treatment is divided into two parts: physical process and chemical process, both of which are indispensable in swimming pool water treatment.
The physical process is that the swimming pool water is purified by filtration of the circulating water treatment device.
Chemical process refers to adding chemical agents to disinfect, flocculate and remove algae while circulating the pool water, and then making the pool water clean and hygienic through physical process.
These two processes can be carried out at the same time to ensure that the water quality of the swimming pool meets the national standards and let your swimming pool pass the inspection of the health and epidemic prevention department smoothly. The most important thing is that people who exercise in the swimming pool can really achieve the purpose of fitness and will not be infected with diseases.
First, the swimming pool water disinfection
Disinfection of swimming pool water is a very important issue. If it is not solved properly, the swimming pool may become a place to spread diseases. The swimming pool is suitable for the growth of pathogenic bacteria such as typhoid fever, paratyphoid fever, dysentery, hepatitis, acute conjunctivitis and pustulosis. Hepatitis virus and encephalitis virus often transmit diseases through water. The disinfection of swimming pool water shall generally meet the following requirements:
1. The disinfection method adopted must have a strong sterilization effect, which can quickly and massively kill bacteria, that is, 99.9% of microorganisms can be killed within 30 seconds;
2, the sterilization effect should have a reasonable duration, which can effectively control the new pollution caused by swimmers entering the pool;
3. For the swimmer's mucosa, the panel must be non-sexual and will not cause odor in the air;
swimming pool
4. The dosage must be easy to control, and the amount and effect of chemicals in water can be quickly determined by simple methods;
5. Considering all relevant factors, the capital investment and transportation cost must be reasonable.
Chlorine disinfection is the most common method. Chlorine can produce hypochlorous acid in water, which will spread to the surface of bacteria, cross the cell membrane and enter the interior of cells. In bacteria, the oxidation of chlorine atoms will destroy an enzyme system in bacteria and eventually lead to the death of bacteria.
An important feature of chlorine disinfection is that it can keep a proper amount of residual chlorine in the disinfected pool water as needed, so that the pool water that is constantly polluted by human body can be continuously disinfected during the use of the pool water. Generally, the residual chlorine content in swimming pool water is required to be 0.4-0.6 mg/ 1. In addition, in order to ensure the efficacy of disinfectant and not cause corrosion of equipment and swimming pool surface, the relative pH value of swimming pool water is required to be kept at 7.4-7.6.
Liquid chlorine and hypochlorite are commonly used for chlorine disinfection. Liquid chlorine has the advantages of simplicity and low cost, and can kill many kinds of bacteria, pathogenic bacteria, viruses and parasitic eggs. It plays a key role in preventing the epidemic of cholera and typhoid fever, but toxic substances that are easy to leak must be stored and used safely. Sodium hypochlorite solution is a commonly used strong bactericide, efficient oxidant and excellent bleaching agent, which has been widely used in all walks of life in China. Compared with other disinfectants, sodium hypochlorite has a broad-spectrum, efficient and rapid disinfection effect, and is safe, non-toxic and has no toxic and side effects on human body, so it is widely used. It is an ideal, safe, convenient and efficient disinfection products among chlorine-containing disinfectants in China. Its available chlorine content is 12.5%- 13.5%, and it is extremely unstable, easy to decompose and not durable.
The evaluation of disinfectant should comprehensively consider its killing ability and stability in water. For the four disinfectants commonly used in water treatment, that is, liquid chlorine, chlorine dioxide, sodium hypochlorite, chloramine and ozone, from the perspective of bactericidal ability, ozone > chlorine dioxide > sodium hypochlorite > liquid chlorine > chloramine; In terms of stability, chloramine > sodium hypochlorite > chlorine dioxide > liquid chlorine > ozone. It can be seen that sodium hypochlorite is an excellent and stable disinfectant, which can be used not only for disinfection of various water bodies, but also for other sanitary disinfection. Performance comparison between sodium hypochlorite generator and several disinfectants;
1, sodium hypochlorite has high solubility in water, and it volatilizes little from water during disinfection, and almost no smell can be heard. However, when liquid chlorine is used for disinfection, due to improper operation, some chlorine gas escapes from the water with strong smell, which requires a certain period of time to stop the pool for ventilation, while sodium hypochlorite disinfection does not need to stop the pool, thus prolonging the pool opening time, allowing disinfection while swimming, with great flexibility, good randomness and less constraints.
2. Liquid chlorine is difficult to transport and store, and it is highly toxic, which is very harmful to people and animals, especially those who operate for a long time, and are prone to bronchitis and bronchitis.
3. Sodium hypochlorite has obvious oxidation, decoloration, deodorization and deodorization effects, which can obviously change the color and smell of water and does not react with ammonia nitrogen and nitrogen-containing organic matter. Sodium hypochlorite is a strong oxidant, which will not react with organic substances in water to generate organic chlorides such as chloramine, chlorophenol and chloroform. It has a strong oxidative degradation effect on carcinogens and organic poisons in water.
4. Sodium hypochlorite has wide bactericidal spectrum, high efficiency and strong killing ability to viruses and spores. Small dosage, short action time and good effect. Practice has proved that sodium hypochlorite is very suitable for disinfection of swimming pool water, killing all kinds of viruses, bacteria and microorganisms spread in water supply.
5. Sodium hypochlorite has the ability to kill and inhibit the growth of algae in water. After adding sodium hypochlorite, the propagated algae can be killed in a short time.
6. The sodium hypochlorite generator produces liquid, which has good stability, safety, no hidden danger, convenient dosing and easy realization of quantitative dosing. However, the chlorine dioxide generator has poor stability and the dosage is difficult to control because it produces gas; If there is a problem in the process of administration, there is still the danger of explosion.
7. All technical indicators of sodium hypochlorite generator have national standards, while chlorine dioxide generator is a nonstandard product, so users can't check the quality of purchased equipment.
8. Chlorine dioxide generator is a comprehensive disinfection gas produced by electrolysis of saturated salt solution. The experiment shows that the chlorine dioxide gas content is low, accounting for only 8- 10%. In addition, the chlorine dioxide generator adopts diaphragm electrolysis, and the filter diaphragm is a permeable membrane, which is easy to block and needs to be replaced frequently. In the process of electrolysis, it is necessary to manually discharge alkali and dilute electrolyte. Sodium hypochlorite generator is diaphragm-free electrolysis, which does not need to change membrane, discharge alkali and dilute electrolyte, so the labor intensity of workers is not great.

9. Taking water as the transport carrier and adding chlorine dioxide to the water to be disinfected is undoubtedly a great waste of water resources. Sodium hypochlorite can be added directly without water as a carrier.
10, the water treatment cost per ton of sodium hypochlorite is about 0.02 yuan, while the water treatment cost per ton of chlorine dioxide is about 0.05 yuan.
In a word, for the disinfection of swimming pool water, sodium hypochlorite disinfection method is efficient, low consumption, safe and reliable, and it is an ideal choice for disinfection products.
Coagulation treatment of swimming pool water
The Water Quality Standard for Swimming Pools stipulates that the turbidity of swimming pool water shall not exceed 5 degrees. The swimming pool water is turbid due to sediment, clay, algae, microorganisms and some organic substances. In order to reduce the turbidity of swimming pool water, coagulation treatment is needed, that is, coagulant is added to the water to absorb the small particles of turbidity in the water, so that they condense into large particles, and finally precipitate is produced and discharged out of the pool through a filter.
Three, swimming pool water algae removal treatment
The water temperature of swimming pool is generally between 20℃ and 30℃, which is very suitable for algae reproduction and growth, such as irregular algae removal treatment. The pool water will turn dark green, which will seriously increase the turbidity of the pool water and make the bottom of the pool black and smelly. In this case, the treatment should be carried out through the following steps: first, adding disinfectant, second, adding algaecide, third, adding flocculant, and fourth, strengthening recycling.
Fourth, the water treatment process
Swimming pool water is easy to treat, and the swimming pool water treatment is divided into two parts, swimming pool circulating water treatment and overflow reuse water treatment.
Generally, the following process flow is adopted. The circulating water of the original swimming pool is directly filtered and then treated with disinfectant. The disinfectant is sodium hypochlorite disinfectant, which is prepared and provided by the sodium hypochlorite generator on site. As for the overflow of the swimming pool, as long as there is no defect in the design of the circulating pipeline, the waste of water caused by system defects is avoided, so there is only overflow within the normal range. For normal swimming pool overflow water, if it is to be treated, it should be coagulated first, then filtered, circulated by the swimming pool pump, disinfected with drugs, and finally entered the swimming pool. The filter material of the main loop filter is generally quartz sand, which has long service life and good algae filtering effect.
water-quality standards
As a water sport, it is inseparable from the control, monitoring and treatment of swimming pool water quality, which requires that the sensory characteristics of the pool water are good, the water does not contain pathogenic microorganisms, and the chemicals contained in the water must not endanger human health, so as to ensure the safety and reliability of the swimming pool water quality.
swimming pool
The implementation of Water Quality Standard for Swimming Pools (CJ 244-2007) will certainly play an important role in the sanitary management of swimming pools in China, preventing the spread of diseases and ensuring the health and safety of swimmers. At the same time, it will provide technical support for the water quality standards of various international swimming competitions to be held in China in the future, which will bring the water quality standards of swimming pools in China into line with those of developed countries and play a very positive role in the smooth hosting of the Beijing Olympic Games.
How to deal with the turbidity of swimming pool water? Generally, the water will be changed regularly, and then bleaching powder will be sprinkled every day to purify the water. Swimming places with relatively high prices have relatively good water quality. At present, there are too few swimming places in Wuhan and the ticket price is relatively high, which needs to be improved.
