Analysis of the principle and practical application of ozonolysis catalyst

Ozone decomposition catalyst can improve the decomposition rate of ozone in water, thereby improving the oxidation efficiency of pollutants in water. This is because strong oxidants such as hydroxyl radicals produced by the catalyst can react with more pollutants in a short time. Moreover, through the action of the catalyst, the decomposition of ozone can be more evenly distributed in the water body, avoiding the situation that the local ozone concentration is too high or too low, making the entire water treatment process more stable and efficient. At the same time, the catalyst can also reduce the amount of ozone used in the treatment process, reducing operating costs.
Ozone decomposition catalyst in swimming pool water treatment case:
Background: Swimming pool water is easily contaminated by human secretions (such as sweat, urine, etc.), cosmetic residues and microorganisms due to the large number of users. Traditional chlorine disinfection can create a pungent odor in pool water and may cause eye, skin and respiratory irritation to swimmers.
Processing process:
Pool water is first passed through a circulating filtration system to remove large particles of impurities such as hair and paper scraps. Ozone is then introduced into the circulating water system. Ozone can quickly kill bacteria in the water (such as Staphylococcus aureus, pseudomonas aeruginosa and other common swimming pool harmful bacteria) and viruses, but also can oxidize and decompose organic matter such as urea in urine. For example, urea is oxidized by ozone into harmless substances such as carbon dioxide and water.
Due to the short half-life of ozone in water, in order to ensure the continuous disinfection effect, a small amount of chlorine disinfectant will be added as an auxiliary disinfectant after ozone treatment. After ozone-chlorine joint disinfection treatment, the water quality of the swimming pool is clear and transparent, the use of chlorine is greatly reduced, the generation of chlorine disinfection byproducts is reduced, the comfort of swimmers is significantly improved, and the renewal cycle of swimming pool water can be extended appropriately, saving water resources.
