Ozone disinfection of swimming pool cleaning equipment 
 Swimming pool water disinfection equipment, UV-O3-date system (UV-Ozone) 
 Overview: 
 For a long time, an artificial pool of sterilization to the use of iodide and chloride, as well as chlorine. Until the twentieth century, ozone technology, only the ozone into the water treatment field, and more and show its superiority. However, in practice there are still many problems: 
 1, ozone machines and the high cost of the reaction tower, causing many users to stop looking; 
 2, complete with ozone gas-water mixer are few, mixing efficiency is low, resulting in a large number of ozone (40% -70%) is not soluble in water and escape. In order to achieve satisfactory disinfection, it must increase the amount of ozone machine, which not only increased investment, but also caused air pollution; 
 3, complete with ozone gas-water mixer, reaction tower and other accessories to each individual purchase, resulting in models messy, difficult to complete, quality is difficult to guarantee; after years of exploration and research, and combined UV and ozone, a new generation of disinfection systems are available, and get good treatment effect, which is the product-UV-O3 disinfection system! UV-O3 disinfection system UV-O3 and ozone disinfection system is a special wavelength ultraviolet disinfection systems together. 
 First, the theoretical basis: scientists found that an increase in the ozone disinfection system in the special wavelength ultraviolet radiation, ozone can stimulate activity and catalytic ozone and water molecules to generate a large number of hydroxyl radicals accelerate (OH ˉ)! Hydroxyl radical (OH ˉ) is the ozone and water reaction of the active substances than hypochlorite (ClO ˉ) 100 times the oxidation capacity, bactericidal properties of a large 3,000 times! Increase in the ozone disinfection system in the special wavelength ultraviolet radiation and its bactericidal effect than simply the use of ozone big 1-2 times! This is the UV-O3 disinfection systems theory. 
 Second, the swimming pool disinfection system using UV-O3 three major roles: 
 1, with the strongest bactericidal effect and inactivated virus, which can effectively prevent the spread of infectious diseases, experiments show that inactivation of fecal E. coli only 5 seconds, with the same concentration of chlorine needed to achieve the same effect 15,000 seconds! Some pathogens such as viruses, amoeba, cysts and other resistant to chlorine, but can not escape being killed by OH-. UV-O3 disinfection system used for swimmers to swim in a safe comfort; 
 2, UV-O3 disinfection system is the oxidation capabilities of the other role, he can avoid creating a special indoor swimming pool odor compounds in water accumulation, including swimmer waste chlorine reaction of chlorine with organic matter accumulation, these compounds have a chloramines, dichloramine three chloramine, THM, chloride, creatine, urine, chlorine, etc., many of them have their own color or odor, and are of THM precursors. Ozone is in fact constantly blocking the generation of these precursors, the swimming pool as clean water, fresh air and eyelids, nasal membrane without stimulation of the fitness sites. Of course, particularly important is the significant decline of THM in water, is to give the fitness of people to create the best conditions; 
 3, UV-O3 disinfection system of the third role is to help filter out sand and organic matter in addition to metal salts, which is due to oxidation of organic matter in the process can easily become a multi-polar compounds, and with the multivalent metal cations such as calcium, magnesium, iron, aluminum, combined into a complex, and a micro-flocculation state in addition to being filtered sand. Ozone water can become blue green, flashing, clear water and be welcomed. 
 Third, the system structure and characteristics: 
 1, UV-O3 disinfection system, water booster pump through the box, mixed with ozone jet pipe, and by the catalytic reaction tank and returned to the pool system. Because of the special wavelength ultraviolet radiation, greatly increasing the OH-formation, accelerated oxidation and sterilization! 
 2, UV-O3 disinfection system, due to the role of UV, not only to ensure that low ozone dosage in the case of a good sterilization, oxidation effects, and avoid the high levels of ozone in water pools (for example,> 0.15 mg / L ) risk. As the role of UV, exposure to the small tank, do not use activated carbon decomposition of ozone, can cancel the exhaust gas treatment equipment, reducing costs; 
 3, UV-O3 disinfection system can reduce the use of chlorine dosage, Phil Castle reported that their condition is similar to the multiple swimming pools, full road, bypass, and UV-03 contrast test, which lasted four months, proved to meet the sterilization, oxidation required in the circumstances, UV-03 system, the amount of chlorine can be further reduced, making the water with chlorine, free chlorine were reduced to 0.2 mg / L, 0.4 mg / L or less, which to some extent, so that the pool water the chloramines and THM have been substantially reduced, which meet increasingly stringent environmental protection requirements will be very important. 
 4, UV-O3 system, synergies of ozone and UV-generated hydroxyl radicals (OH-), on the oxidative decomposition of organic pollutants is very powerful! Free radical formation and the role of organic pollutants under the action of the UV optics, almost instantaneous, time is very short, and only in the UV light to proceed. This pool of water there is human excrement - sweat, uric acid, urea clearance is important! In the past, the existence of human waste pool water is very difficult to remove. 
 5, disinfection system using UV-O3 ozone disinfection than individual investments to reduce more than 40%, the economy was good.
