Principle of ozone sterilization
Ozone is a strong oxidant and the sterilization process is a biochemical oxidation reaction. Sterilization has the following three forms: 1. Ozone can oxidize and decompose the enzymes required for glucose inside the bacteria, causing the bacteria to inactivate and die. 2. Directly interact with bacteria and viruses, destroying their organelles and DNA, RNA, and destroying the metabolism of bacteria, leading to bacterial death. 3. Through the cell membrane tissue, invading the cells, acting on the outer membrane of lipoproteins and internal lipopolysaccharides, causing the bacteria to undergo permeability distortion and dissolve and die. The advantage of ozone sterilization ozone sterilization method as bacteriolysis level, complete sterilization, no residual, broad spectrum sterilization, can kill bacteria and spores, viruses, fungi, etc., and can destroy the botulinum toxin. In addition, O3 also has a strong killing effect on mold. O3 is quickly decomposed into oxygen or a single oxygen atom due to its poor stability. A single oxygen atom can combine itself into oxygen molecules without any toxic residues. Therefore, O3 is a non-polluting disinfectant. O3 is a gas that can quickly diffuse into the entire sterilization space, and there is no dead angle in sterilization. The traditional sterilization and disinfection methods, whether UV or chemical fumigation, have incomplete, dead angles, large workload, residual pollution or odor, and may damage human health. If UV disinfection is used, there is no effect in places where light is not exposed, and there are disadvantages such as decline, weak penetration, and short service life. Chemical fumigation methods also have shortcomings, such as bacteria and viruses that are highly resistant to medicinal properties, and the bactericidal effect is not obvious. The presence of ozone-ozone disinfection sterilization as an alternative to chlorine disinfection is increasingly used in drinking water treatment. Tests have shown that ozone has an almost inactivated effect on almost all bacteria, viruses, fungi, protozoa, and oocysts. However, bromate is produced when ozone oxidizes raw water containing bromide ions. Bromate has been identified as a Class 2B potential carcinogen by the International Agency for Research on Cancer. WHO recommends a large bromate content of 25 μg/L for drinking water. The US Environmental Protection Agency (USEPA) drinking water standard specifies a high allowable concentration of 10 μg of bromate. /L. The formation of bromate in the process of ozone oxidation has two pathways: ozone oxidation and ozone/hydrogen radical oxidation. Controlling bromate can be carried out by controlling its formation and removal. Lowering the pH, adding ammonia, the chlorine-ammonia process, and optimizing the ozonation conditions are methods for controlling the formation of bromate, which can be removed by physical, chemical, and biological methods. Therefore, to achieve the balance between ozone , pathogenic bacteria and bromate, it is necessary to further explore the ozone sterilization mechanism and the bromate control method. So don't rush to drink after the bottled water is bought home. The insurance method is to put it for a day or two to let the bromate in the water break down into harmless bromide before drinking. Ozone air disinfection precautions 1. Ozone is irritating to human respiratory mucosa. When the concentration of ozone in the air reaches 1mg/L, it can be smelled out. When it reaches 2.5-5mg/L, it can cause pulse acceleration, fatigue and headache. If people stay for more than 1 hour, Emphysema can occur, leading to death. Therefore, the disinfection of ozone with ozone must be in the absence of people, less than 30 minutes after disinfection can enter. 2, ozone is a strong oxidant, damage to a variety of items, the higher the concentration, the more damage to the item, the copper granules appear green rust, rubber aging, discoloration, reduced elasticity, resulting in brittleness, breakage, bleaching and fading of fabrics, etc. . The effect of ozone sterilization is the speed and effect of ozone sterilization. Its high oxidation-reduction potential determines its wide application in oxidation, decolorization and deodorization. Some studies have pointed out that ozone dissolves in water and can almost kill all pairs of water. Harmful substances such as iron, manganese, chromium, sulfate, phenol, benzene, oxides, etc., can also decompose organic matter and kill algae. Shanghai Sujing Industrial Co., Ltd.
