Comparison of advantages and disadvantages of using ozone and chlorine dioxide in swimming pools

ozone and its secondary products (such as hydroxyl) have the strongest bactericidal and inactivating effects, which can effectively prevent the spread of infectious diseases. Experiments have proved that the effect of ozone at the same concentration on killing bacteria and viruses is times that of chlorine. When the ozone concentration is 1mg/l, the inactivation of fecal Escherichia coli takes only 5 seconds, and it takes 15000 seconds to achieve the same effect with the same concentration of chlorine

ozone is an internationally recognized environmental friendly green fungicide, which will not cause any secondary pollution to the environment. Chlorine agents will react with organics in water to produce a variety of chlorinated organic compounds, such as chloroform, chloroform, etc., which are recognized as carcinogens and mutagens. When people swim, these toxic substances will be absorbed by the human body (in water, the human body can absorb 500 ml of water per hour). Chlorinated organic compounds in water can also irritate people's eyes and skin, causing red eyes and rashes

◆ chlorinated organic compounds and toxic gases such as chlorine evaporated from water damage human respiratory organs, which will not be caused by the use of ozone

◆ the acidic substances produced by chlorination seriously corrode the water treatment system and the equipment and structures in the museum, such as shelves, heating, etc

◆ ozone is the strongest oxidant, which can effectively decompose the humus in the water. After oxidizing the iron and manganese ions in the water and supporting the steel strand clamp, it decomposes the micro organisms that scatter light in the water, so as to greatly improve the clarity of the water and make the water appear beautiful blue, while chlorine preparation has no such effect. In order to make the water blue, it is necessary to repair the color in time. Swimming pools using chlorine agents often need to add copper salt, which is extremely harmful to people

◆ after adding chlorine preparation, it will inevitably lead to the change of pH value of water at present, making people feel uncomfortable, so it is necessary to add alkaline or acidic substances for neutralization. Ozone is a neutral substance, which will not cause this problem

◆ ozone can ensure the stability of water quality in high passenger flow and high temperature seasons. Water quality is often poor in high temperature and high passenger flow. At this time, if chlorine agents are used, they need to be added in large quantities, which will bring a series of side effects, such as pH changes, irritation to respiratory tract and human body, etc; However, a large amount of ozone has no such side effect

◆ using ozone generator can greatly reduce the management and operation difficulty of water treatment process. At the same time, ozone generator has high safety, and chlorine agents have certain risks in transportation, storage and use

◆ ozone can decompose organic matter in water and has micro flocculation effect, so flocculant can not be used under normal passenger flow

Guide and promote the standardization and orderly development of the new material industry

under certain service conditions, such as countercurrent circulation and no use of activated carbon filter tank, ozone can be used as the only agent in the water, without adding chlorination agents, flocculants and pH regulators. (end)
