Swimming is a sport that integrates entertainment and fitness. Healthy, comfortable and safe water quality in the swimming pool will bring physical and mental enjoyment to the swimming lovers. In the process of swimming pool water immersion, a large amount of dirt and secretions will inevitably be produced, and a variety of bacteria and pathogenic bacteria will enter the water. Therefore, the swimming pool water must be treated to kill harmful bacteria, ensure good transparency, and provide a comfortable, tasteless and pollution-free healthy water quality. At present, swimming pool water disinfection treatment mainly chlorine disinfection method, chlorine dioxide method, ozone disinfection method, electrostatic sterilization and algal elimination method, copper sulfate algal suppression method. As a classic water treatment disinfection method, chlorine disinfection has a history of more than one hundred years and is still widely used because of its advantages such as strong disinfection ability, low price and wide sources. The bactericidal effect of chlorine agent is mainly due to its strong oxidation and easy to penetrate the cell wall characteristics. The main factors affecting the disinfection effect of chlorine agent are the amount of chlorine, contact time, pH value, water temperature, turbidity, the type and number of microorganisms in the water. In recent years, more and more attention has been paid to the environmental and safety problems caused by chlorine disinfection. As chlorine disinfectant kills bacteria and viruses, it also forms chlorinated amine and trihalomethane (THM) with urea and organic matter secreted by human body. The volatility of amine chloride can cause special odors in indoor swimming pools and cause irritation to human eyes, ears, nose and throat mucous membranes. THM has been confirmed as carcinogenic to mice. The US Environmental Protection Agency (EPA) announced that THM is harmful to health in 2001, saying that drinking water with excessive THM for a long time may lead to lung, liver and central nervous system cancer, and THM in swimming pool water can cause certain harm to health through human respiration and skin penetration. In order to reduce the content of chlorinated amine and trihalomethane in swimming pool water and reduce their harm, they can be removed by coagulation precipitation, activated carbon adsorption and filtration. Using chlorine dioxide or ozone disinfection method, can completely solve the above problems. In the 1940s, chlorine dioxide was found to have a good effect on water disinfection in some European countries, but it was not paid much attention because of its complex manufacture and high price. In recent years, the research and application of chlorine dioxide are increasing in order to find new disinfectants to avoid the harmful effects caused by chlorine disinfection. It is found that chlorine dioxide disinfection method has the following advantages:

(1) can reduce the formation of chlorinated byproducts such as trihalomethane in water;

(2) When the ammonia content in water is high, it does not react with ammonia, so its oxidation and disinfection effects are not affected;

(3) can kill pathogenic microorganisms and viruses in water;

(4) The disinfection effect was not affected by the pH of water quality;

(5) After chlorine dioxide treatment, the residual chlorine in water is stable and durable, and the ability to prevent re-pollution is strong;

(6) Due to strong oxidation, can remove the color and taste of water, and do not form chlorophenol odor with phenol;

(7) The removal effect of iron and manganese is better than that of chlorine. Of course, chlorine dioxide disinfection also has some disadvantages:

(8) Chlorine dioxide is explosive and must be prepared on site for immediate use;

(9) The preparation of chlorine dioxide with low chlorine content is more complicated and its cost is higher than other disinfection methods;

(10) The raw materials for the preparation of chlorine dioxide are sodium chlorate and hydrochloric acid, which are oxidizing or corrosive substances and also have safety problems in storage and transportation;

(11) Safety of the preparation device itself. The safety of storage, transportation and preparation of raw materials limits its wide application in swimming pool water treatment.

[Ozone disinfection technology for swimming pool water treatment] due to the oxidation of ozone is very strong, can decompose organic matter one hundred times higher than chlorine reaction rate, can effectively prevent the combination of chlorine and urea into chloramine, but also can oxidize the precursor of THM, and THM greatly reduced. After ozone decomposition, the hydroxyl group formed in water can hydrolyze the polyvalent metal ions into colloidal compounds, which are filtered out through the sand filter. It not only improves the perception of water, but also removes the organic matter decomposed by oxidation in water. Compared with the chlorine disinfection method, the water quality and venue environment improved significantly after using ozone technology for swimming pool water treatment:

(1) Ozone and its secondary products (such as hydroxyl) have the strongest bactericidal and inactivation of viruses, which can effectively prevent the spread of infectious diseases. Experiments have proved that the same concentration of ozone is 600-3000 times more effective than chlorine in killing bacteria and viruses. When the concentration of ozone is 1mg/L, it only takes 5 seconds to inactivate fecal Escherichia coli, while it takes 15000 seconds with the same concentration of chlorine.

(2) Belong to the international recognized environmental protection green fungicide, will not cause any secondary pollution to the environment.

(3) When chlorine is used for disinfection, toxic gases such as chlorinated organic compounds and chlorine gas that evaporate from the water gather above the pool and are not easy to disperse, damaging people's respiratory organs and seriously affecting people's health. However, the use of ozone will not cause such problems.

(4) Ozone can effectively decompose humus in water, oxidize iron and manganese ions in water, decompose tiny organisms scattering light in water, thus greatly improving the clarity of water, making water appear beautiful blue, while chlorine preparation has no such effect. In order to make the water blue, the use of chlorine preparation of the pool, often need to add copper sulfate salt, extremely harmful to people.

(5) After adding chlorine preparations, it will inevitably lead to the change of pH value of water, making people feel uncomfortable, so it is necessary to add alkaline or acidic substances to neutralize. Ozone, however, is neutral and does not cause such problems.

(6) The use of ozone generator, can greatly reduce the water treatment process management and operation difficulty, at the same time has a high safety. However, chlorine preparation has certain danger in transportation, storage and use.

(7) Ozone can decompose organic matter in water and has micro flocculation, so under normal passenger flow, flocculant can not be used.

(8) Under certain use conditions, it is unnecessary to add chlorine elimination agent, flocculant, pH regulator, ozone can be used as the only treatment agent.

Electrode method to manufacture sodium hypochlorite principle is to use no diaphragm electrolysis, through homogeneous secondary chemical reaction to generate sodium hypochlorite. The anode works by electrolyzing sodium chloride (a pill) into a swimming pool. In the electrolytic process, sodium hypochlorite is formed. The most suitable salt concentration is 3%-5%. The electrodes used in the sodium hypochlorite generator are plate electrode and tube electrode. Anode material can be coated titanium electrode. Mixed oxide coated titanium anode, long service life, this coating titanium anode is also relatively low over potential, high chlorine current efficiency, good energy saving effect. The anode of Baoji Ruicheng Titanium Co., Ltd. has high efficiency and long service life.
