1. Conventional swimming pool water purification usually requires special equipment. The treatment process is: swimming pool backwater-hair collector-flocculant addition-multimedia filter (deep impurity removal)-sterilization system-heating system (water temperature adjustment)-swimming pool water intake.
There is also a small swimming pool, in which disinfectant water is poured directly.
2, 3 The sterilization of swimming pool water generally involves three kinds: sodium hypochlorite (medicine); Chlorine dioxide (generator); Ozone (generator)
The first two kinds are sterilized with available chlorine, and the content of available chlorine in water can reach 2~5ppm. The sterilization effect lasts for a long time, but it will produce an odor (imagine the taste of disinfectant).
Ozone equipment is more expensive than the first two, and its strong oxidation makes it kill bacteria faster. At the same time, it decomposes quickly, and it will become oxygen after about 15min, which is good for water and has no effect on human body, but it also has no continuous sterilization effect.
At present, the water treatment of high-grade swimming pools in China is ozone sterilization, and the swimming pools in international competitions are also ozone sterilization.
4. Water treatment chemicals are chemicals after all, which are not good for human body. If it is added, it is better to handle it with equipment. If it is added directly to the swimming pool, it is even more necessary to master the dosage.
