Structure and facilities of pool bottom return water system: bottom discharge
1. The return water method of skimmer with bottom drain and overflow tank with bottom drain - swimming pool equipment-
The skimmer is used in small and medium-sized swimming pools. Generally, when the pool water area is ≤ 350 square meters, a skimmer is used. If there is no water area of 25-50 square meters, one skimmer is used, and a swimming pool should not have less than 2 skimmers. Outdoor pools are installed in the downwind of the swimming season (the north wall pool), and 50% to 70% of the water flow can be treated by the skimmer. Different pollution situations can be treated with special treatment, and special cases of 0-100% treatment by the skimmer may occur. The skimmer is used to treat impurities with a specific gravity of less than 1kg/l and equal to 1kg/l, while the bottom row is used to treat impurities with a specific gravity greater than 1kg/l and equal to 1kg/l. This cyclic method is scientific when dealing with pollutants with different specific gravities- Swimming Pool Equipment-
The overflow tank is used for the physical treatment of the Zhongda swimming pool and must be equipped with a balanced water tank. 70% -100% of the water flow can be treated through the overflow tank, which can overflow around the pool edge or on the two long sides of the pool. The bottom row also participates in circulation filtration. The function of the overflow tank is the same as that of a skimmer, which treats impurities with a specific gravity of less than 1kg/l and equal to 1kg/l, while using bottom discharge to treat impurities with a specific gravity greater than 1kg/l and equal to 1kg/l. This circulation method treats pollutants with different specific gravities and is also scientific.
Explanation: The balanced water tank is not built and installed in the computer room, but is constructed of concrete next to the swimming pool, which can be conveniently used for sewage suction and chemical treatment. When in a stationary state, the water surface of the swimming pool and the water level of the balance tank are at the same level below the ground. After the system works, the circulating water pump draws water from the balance tank, and after passing through the circulation, filtration, heating, and disinfection systems, it replenishes the swimming pool. The water level of the balance tank decreases, while the water level of the swimming pool rises, forming a water level drop. This allows the overflow tank to return water and flow impurities with a specific gravity less than 1kg/l and equal to 1kg/l. At this time, the bottom row can work simultaneously to flow impurities with a specific gravity greater than 1kg/l and equal to 1kg/l. It should be noted that if water is supplied from the bottom of the pool, the so-called "short flow" phenomenon can be ignored, because the water entering the swimming pool from the water supply port immediately mixes with untreated pool water after entering the pool, and the mixed water with dirty water flowing back to the bottom discharge cannot be called "short flow"- Swimming Pool Equipment-
