Ozone is an allotrope of oxygen. Its chemical formula is O3, also known as triatomic oxygen and superoxide. It is named for its fishy-like odor and can be reduced to oxygen by itself at room temperature. When we talk about ozone, we think of ozone pollution, an environmental pollution problem that has been gradually paid attention to. But today we are going to talk about the role of ozone itself. What uses can it play in life or production?

We learned from the Beidou Think Tank Environmental Stewardship website that ozone has strong oxidizing properties and is very unstable. It can be decomposed into oxygen at normal temperature and normal pressure. No secondary pollutants are produced during the conversion of ozone with oxygen, which is the greatest advantage that ozone can be used in almost all fields. Ozone applications are divided into four fields according to their uses: water quality treatment, chemical oxidation, food processing and preservation, and medical treatment. Common ones are environmental protection, medical care, food industry, aquaculture and planting, indoor disinfection, and agricultural production.

First the application of ozone in water treatment

Ozone is used to treat industrial sewage and domestic sewage. It can oxidize redundant or toxic inorganic substances, such as cyanide, etc., to oxidize and remove organic substances in water, especially organic substances that are difficult to degrade by microorganisms, such as surfactants, reduce BOD and COD in water, and inactivate Viruses and bacteria in the water will generate clean and harmless disinfection water. It can be widely used in drinking water sterilization, reclaimed water reuse and purification, sewage treatment, greenhouse soil disinfection, swimming pool water treatment and hospital sewage treatment.

Second, the application of ozone in the field of health care

Ozone can be used for sterilization and disinfection of space air in medical places. Ozone water can disinfect the hands of doctors and nurses before surgery in hospitals, and can inactivate all bacteria. Not only does it take a very short time, but its bactericidal power far exceeds that of alcohol and chlorine. And ozone water has reliable safety.

Ozone has anti-inflammatory and analgesic properties. The application of ozone in dentistry is earlier, and it is often made into an aqueous solution containing ozone for cleaning wounds. Ozone water can be used to disinfect wounds and treat skin diseases caused by various bacteria, fungi and viruses. Ozone can also be used to treat joint pain, local soft tissue injury, etc., such as lumbar muscle strain, frozen shoulder and other soft tissue acute and chronic injuries, mainly caused by aseptic inflammation to cause symptoms. Rapid anti-inflammatory and analgesic effects, improve discomfort symptoms.

Third, the application of ozone in the food industry

The purpose of applying ozone in the food processing industry has four aspects: one is to inactivate microorganisms - sterilization; the second is to oxidize and decompose organic or inorganic pollutant gases - deodorization and purification; the third is to decompose fruit and vegetable metabolites and inhibit the post-ripening process - -Preservation; Fourth, degradation of pesticide residues in foods such as fruits and vegetables-removal of residues. The application basis of the four aspects all rely on the strong oxidizing properties of ozone and the characteristics of unstable and easy decomposition.

The principle of ozone deodorization is really not to cover up the odor with odor, but to decompose the source of the odor. Ozone reacts with odorous organic compounds to form new non-odorous products. The fresh-keeping function is to decompose the physiological metabolism of fruits and vegetables through ozone oxidation, and the breathed ethylene gas and ethylene intermediates also have an inhibitory effect on microorganisms such as mold.

Fourth, the application of ozone in livestock and poultry breeding industry

In the process of livestock and poultry breeding, it can quickly inactivate various common bacteria, infectious viruses, fungi, mycoplasma, spirochetes and other pathogenic microorganisms in the indoor air of the farm, and remove a large amount of ammonia, hydrogen sulfide and methane produced by the fermentation of feces. and other harmful gases and feces odor, reduce livestock and poultry diseases, especially prevent the outbreak of large-scale epidemic diseases, improve the survival rate and livestock product output, save labor and drug costs, and improve the production environment in the field.

Five, the application of ozone in industry

Ozone is also widely used in industrial manufacturing, as an oxidant, catalyst and refining agent in the chemical, petroleum, paper and textile, pharmaceutical and flavor and fragrance industries; in the pulp and paper industry, ozone can be used for chemical pulp bleaching or mechanical properties of mechanical pulp The improvement can reduce the environmental pollution caused by chlorine in the pulp bleaching process.
