1. Direct water supply
That is, on the one hand, new water is continuously injected into the swimming pool equipment; on the other hand, the contaminated pool water is continuously discharged through the drain at the bottom of the pool or the overflow trough at the side of the pool. According to the requirements of the specification, the amount of fresh water supplied per hour for this water supply method should not be less than 15% of the pool volume, and there should be a backflow prevention device for the discharged sewage.
2. Change the water regularly
That is, the pool water of the fresh swimming pool equipment is completely drained after several days of use, and then the bottom of the pool is cleaned and new water is injected. In this form, if the water exchange cycle is long, the water quality will be polluted seriously and it is difficult to meet the sanitary requirements; if the water exchange cycle is shortened, it is very uneconomical.
3. Regular processing of water supply method
That is, every day after the museum is closed, the pool water of the swimming pool equipment is disinfected, and coagulant is used to collect and precipitate the dirty suspended solids in the pool water, and then use the "sewage drainer" to remove the pollution, and then add a part of fresh water. To ensure normal use the next day. There are two types of "sewage drainer", one is a siphon suction device that utilizes manpower. With this kind of sewage suction device, the amount of sewage sucked and discharged every day only accounts for about 5% of the volume of the swimming pool.
4. Circulating filtered water supply
That is to say, the swimming pool equipment is equipped with independent water purification equipment, and the contaminated pool water in the swimming pool is pumped back, purified and disinfected and then sent back to the swimming pool for use. This is a reasonable water quality treatment method, which saves manpower and ensures a higher standard of hygiene. Require.
