Swimming has many advantages. For office people who are sedentary and prone to shoulder and neck discomfort, the spine can exercise without heavy pressure due to the buoyancy of water during swimming, which is conducive to relieving shoulder and neck discomfort and pressure. Regular swimming can help improve blood circulation, increase vital capacity and delay aging.

However, when some people think that there may be disinfectants, urine and dandruff in the swimming pool, many people are deterred.

So,




Common swimming pool water quality indicators图片

01

urea



The urea in the artificial swimming pool is required to be 3.5mg/L or less. Too high urea value will easily irritate the skin and cornea, causing tooth allergy, acid and hardness.

02

Free residual chlorine



The free residual chlorine reflects the continuous disinfection ability of the disinfectant in the swimming pool. The free residual chlorine in the pool water should be controlled at 0.3~1.0mg/L, which can achieve the disinfection effect without harming the human body.

03

PH value



Hygienic requirements are 7.0~7.8. Within this range, it can keep the disinfectant active and continue to play a bactericidal role.


04

temperature



The standard stipulates that the water temperature of the artificial swimming pool should be between 23~30 ℃, and the appropriate water temperature can allow people to stretch their blood vessels during exercise.

How to judge the water quality of swimming pool

01

Look at the publicity



The health reputation sign is a comprehensive assessment of the health status of the swimming pool, including water quality, ventilation system, public goods, health management and other indicators. It needs to be publicized at a conspicuous location.

The swimming pool shall also publicize the health license, health certificate of employees, health inspection report, self inspection results and measurement time when the swimming pool is open.



02

See turbidity



The swimming pool with good water quality has no suspended particles on its surface. The water in the pool is clear and bottomless, with no stain or sediment. The visibility is generally above 20 meters.

03

Smell



Close to the pool water, you should be able to smell the faint "disinfection water smell". If the "chlorine smell" is too strong or even chokes people, it is likely that the residual chlorine exceeds the standard.


04

Actual feeling



Stir the water with your hands to feel if there is any obvious skin discomfort. If skin itching and pain occur after entering the water, eliminate the cause of skin sensitivity, and the residual chlorine and bacteria in the water may exceed the standard.
