Teach you four ways to quickly judge the water quality of swimming pools.
"Wang"
Generally, the pool water with up-to-standard water color and turbidity is crystal clear. If you can see 20 meters away from the pool, or stand on the pool, you can see that the third waterline is qualified.
smell
You can smell the faint smell of chlorine on the water surface, and the water quality is generally qualified. The smell of chlorine odor means that the organic matter in the pool water is properly treated and thoroughly disinfected, and the baby will not have red eyes, red noses and other stimuli.
"Ask"
Swimmer's skin/taste reaction represents the health of the pool water and the comfort of the swimmer. However, if there is a pungent smell of medicine, or an unpleasant smell, or it feels itchy and painful, then the water quality is unqualified.
"cut"
If there is no sediment at the bottom of the pool, the foam in the pool water dissipates within 15 seconds, which means that the pool water is frequently replaced, otherwise it means that the water quality is unqualified.
