How does ozone disinfect the air?

Ozone (O3) is an allotrope of oxygen, a light blue gas with a special smell. The molecular structure is triangular, the bond angle is 1 16, the density is 1.5 times that of oxygen, and the solubility in water is 10 times that of oxygen. Ozone is a strong oxidant, and its redox potential in water is 2.07V, second only to fluorine (2.5V), and its oxidation capacity is higher than chlorine (1.36V) and chlorine dioxide (1.5V). It can destroy the cell wall of bacteria, quickly spread into cells, and oxidize glucose oxidase. It is necessary to oxidize glucose in bacteria and can also be directly combined with chlorine dioxide. It destroys cells, ribonucleic acid (RNA), decomposes macromolecules such as deoxyribonucleic acid (DNA), RNA, protein, lipids and polysaccharides, and destroys the metabolism and reproduction process of bacteria. Ozone kills bacteria because of the rupture of cell membrane. This process is called cell dissipation, which is produced by the squeezing of cytoplasm in water. In the case of dissipation, cells cannot regenerate. It should be pointed out that, unlike hypochlorous acid disinfectants, the sterilization ability of ozone is not affected by the change of PH value and ammonia gas, and its sterilization ability is 600-3000 times greater than that of chlorine gas, and the sterilization and disinfection effect is almost instantaneous. When the ozone concentration in water is 0.3-2 mg/L, bacteria can be killed within 0.5- 1 min.

The virus proves that ozone has a very strong killing effect on the virus. For example, when the ozone concentration is 0.05-0.45 mg/L, Polay virus will lose its activity within 2 minutes.

② After 2.4min of ozone with the concentration of 0.3 mg/L, the cyst was completely removed. ..

(3) Due to the protection of spore coat, the ozone tolerance of spores is 10- 15 times higher than that of growing bacteria.

④ It can kill fungi Candida albicans and Penicillium.

Kill the parasite Schistosoma mansoni after 3min minutes.
