The swimming pool water quality standard is as follows: PH value 6.5-8.5. The turbidity is not more than 5 degrees or the transparency of the pool water should be at a depth of about 1.5m, and the bottom of the pool can be seen clearly on both sides of the bank. Oxygen consumption should not exceed 12mg/l. Swimming residual chlorine should be 0.4-0.6mg/l, combined residual chlorine should be above 1.0mg/l. The total number of bacteria shall not exceed 18/L. Urea should not exceed 3.5mg
As water sports, it is indispensable to control, monitor and treat the water quality of swimming pools. It is required that the sensory properties 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 water quality of swimming pools.
Pool water quality
1. The water quality of swimming pool should conform to the current national industry standard“Swimming pool water quality standard” CJ244.
2. The water quality of swimming pools with special requirements for important international competitions and special requirements should meet the relevant requirements of the International Swimming Federation (FINA).
Swimming pool water is relatively easy to treat water, swimming pool water treatment is divided into two parts, namely swimming pool circulating water treatment and overflow reuse water treatment. Generally use the following process. 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. Swimming pool overflow water, as long as there is no defect in the design of the circulating pipeline, avoids the waste of water caused by system defects, so there is only overflow water within the normal range. For the normal swimming pool overflow, if you want to deal with, the first coagulation treatment, and then filter, swimming pool circulation pump, and then add disinfection, and finally into the swimming pool. The filter material of the main circulating filter tank is generally quartz sand, which has a long service life and good algae filtering effect.
