What are the swimming pool design specifications

We often see on TV in the summer that some people get sick and bacteria because they go to the swimming pool. Some are due to poor management, others are because the swimming pool design specifications are not up to standard. What kind of pool design is in compliance with the standard? Let's take a look at what are the pool design specifications.

1. The standard swimming pool design is different from the general swimming pool design in size requirements. The standard swimming pool is 50 meters long and 21 meters wide. The Olympic World Championship requires a width of 25 meters. In addition, there is a swimming pool with a length of only half or 25 meters called a short pool. The water depth is greater than 1.8 meters. There are 8 lanes, each of which is 2.5 meters wide and 0.5 meters for the side lanes. There is a lane line between the two lanes. The lane line is hung on both ends of the pool wall by buoy lines. The centerline of the swimming lane shall be set with the end wall of the pool, as a black marking line.

2. Good design specifications for swimming pools include the need to install overflow tanks on the two side walls of the swimming pool to maintain the requirements of the pool water and try to remove floating debris on the surface. The swimming pool ladder should be embedded in the pool, the number is generally 4-6, and its position should not affect the referee's work. The pool wall must be vertical and flat, the bottom of the pool is non-slip, and the surface of the pool is smooth and easy to clean. Generally, the wall of the pool is pasted with white Masek, the bottom of the pool is pasted with white glazed tiles, and the lane markings are black glazed tiles.

3. In addition to the design of the appearance of the swimming pool, the design specification also includes the design of the circulation. Swimming pool water treatment is divided into two parts: physical process and chemical process. These two processes are indispensable in the swimming pool water treatment process. The physical process is that the pool water is purified by the filtering effect of the circulating water treatment equipment. The chemical process refers to adding chemical agents to disinfect, flocculate, and remove algae while the pool water is circulating, and then the pool water is cleaned and sanitary through the action of physical processes.

4. Swimming pool water disinfection is a very important problem. If it is not solved well, the swimming pool may become a place to spread diseases. The temperature of the water in the swimming pool is suitable. It is a suitable growth environment for pathogenic bacteria such as typhoid fever, paratyphoid fever, dysentery, hepatitis, acute conjunctivitis, pustular disease. Hepatitis virus and encephalitis virus often spread disease through water. The disinfection work must be done well.

5. Pool water disinfection must be done. The disinfection method adopted must have a strong sterilization effect, which can quickly and massively kill bacteria, that is, 99.9% of microorganisms within 30 seconds; the disinfection effect should have a reasonable duration The new pollution effect that can bring swimmers into the pool is effectively controlled; the mucous membranes of swimmers must be non-irritating to the skin, and there will be no bad smell in the air.

6. In the swimming pool design specification, the sea should pay attention to the treatment of swimming pool water. The water treatment of swimming pools is divided into two parts, namely the circulating water treatment and overflow water treatment of swimming pools. Generally use the following process. The original circulating water of the swimming pool is treated by direct filtration and added with a disinfectant. The disinfectant is a sodium hypochlorite disinfectant, which is prepared and provided on-site by a sodium hypochlorite generator. As for the overflow water of the swimming pool, as long as the design of the circulation pipeline is not defective, waste water due to system defects is avoided, so that there is only overflow water in the normal range.

7. In the swimming pool design specification, for normal swimming pool overflow water, if it is to be treated, it should be coagulated first, then filtered, and the swimming pool circulating pump, and then disinfected by medicine, and finally enter the swimming pool. The filter material of the main circulation filter tank is generally quartz sand, which has a long life and has a good filtering effect on algae.
