Swimming pool water supply method and other circulation methods
2023-06-20
There are two water supply methods for swimming pools: horizontal water supply on the wall of the pool and vertical water supply on the bottom of the pool, and the two water supply methods are used independently.
1. Two water supply methods: horizontal water supply on the wall of the pool and vertical water supply on the bottom of the pool
There are two water supply methods for swimming pools: horizontal water supply on the wall of the pool and vertical water supply on the bottom of the pool, and the two water supply methods are used independently.The horizontal water supply of the pool wall is very convenient for construction, installation and operation. It is a commonly used water supply method, but its disadvantage is that the heat distribution and chemical dosing are uneven; the advantage of the vertical water supply at the bottom of the pool is that the heat distribution and chemical dosing are relatively uniform, but it is more difficult to construct and install.
2. Scientific circulation method of swimming pool
There are two types of water supply methods: vertical water supply at the bottom of the pool and horizontal water supply at the wall of the pool.；
There are also two backwater methods: the backwater of the skimmer plus the bottom discharge, and the backwater method of the overflow sink plus the bottom discharge.
By arranging and combining the 2×2 water supply and backwater methods, four circulation methods can be obtained. These circulation methods are used abroad. They are：
Circulation method: The bottom of the pool is supplied with water vertically, and the overflow sink is added to the bottom and discharged back to the water system.
Common circulation methods: horizontal water supply on the wall of the pool, and the bottom of the skimmer is discharged back to the water system.
Available cycle methods: A. The bottom of the pool is supplied with water vertically, and the bottom of the skimmer is discharged back to the water system.B. The wall of the pool supplies water horizontally, and the overflow sink is added to the bottom to drain back to the water system.
Conclusion: The scientific circulation method is to ensure that all pollutants of different specific gravity flow through the circulation in the circulating filtration system, and then intercept, stratify and remove.If the water surface of the swimming pool does not circulate, the water surface is a backwater area; if the bottom of the pool does not circulate, the bottom of the pool is a backwater area.The two situations of the dead water area on the surface of the water and the dead water area at the bottom of the pool occur in our downstream circulation method and countercurrent circulation method, which are situations to be avoided abroad.
In the circulating filtration system of swimming pools, the biofilms of the balanced water tank, the balanced water tank, the filter medium, and the inner wall of the pipe valve are important links that have not been paid attention to in the water treatment of swimming pools in our country, and they must be treated with physical treatment and chemical treatment.The traditional downstream circulation method, countercurrent circulation method and mixed flow circulation method in our country do not consider the treatment of this biofilm, and these three circulation methods affect and hinder the treatment of balanced water tanks or balanced water tanks to varying degrees in structure and construction.
In the practice of swimming pool engineering abroad, the backwater method of the skimmer and the bottom row does not require a balanced water tank. Only when the backwater method of the overflow tank and the bottom row is used, the balanced (balanced) water tank can be used. It can be easily physically treated (such as sewage suction) and chemically treated (disinfectants, flocculants, and chemical impact treatment are added).
