The starting platform should be equipped with a handshaker for backstroke, which is 30 ~ 60 cm away from the water surface. There are two types: horizontal and vertical. There should be numbers indicating the number of lanes around the departure platform, arranged from right to left according to the departure direction.

(6) The swimming pool needs to install overflow tanks on both sides of the wall to keep the requirements of the pool water and try to discharge the floating dirt on the surface. Swimming pool ladders should be embedded in the pool, the number is generally 4~6, and their positions should not affect the referee's work.

Fold and edit this paragraph for 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 swimming pool water is filtered and purified by circulating water treatment equipment.

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.
