The principle of ozone disinfection can be regarded as an oxidation reaction.
(1) The mechanism of ozone inactivation of bacteria:
The inactivation reaction of ozone to bacteria is always very rapid. Different from other bactericides: Ozone can react with the double bonds of the lipids on the bacterial cell wall, penetrate into the bacterial body, act on proteins and lipopolysaccharides, change the permeability of the cells, and cause the death of the bacteria. Ozone also acts on nuclear materials in cells, such as purines and pyrimidines in nucleic acids to destroy DNA.
(2) The inactivation mechanism of ozone on the virus:
The first effect of ozone on the virus is the four polypeptide chains of the virus‘s chlamydia protein, and it damages the RNA, especially the protein that forms it. After the phage was oxidized by ozone, electron microscopy showed that its epidermis was broken into many fragments, from which a lot of ribonucleic acid was released, which interfered with its adsorption to the depository.
The thoroughness of ozone sterilization is beyond doubt, and the principle of ozone sterilization can be regarded as an oxidation reaction.

The thoroughness of ozone sterilization is beyond doubt
After World War II, the ozone application technology in the world has made great progress. First of all, in 1902, Paderborn, Germany, established the first large-scale water plant that uses ozone to treat water quality, creating a precedent for ozone water treatment. Now in the world, it is used for sterilization, removal of pollutants, and decolorization. Emission Standards. In Japan, wastewater is treated with ozone and used as reclaimed water in water-scarce areas. . The United States, Japan, Germany, France and other countries have established large-scale sewage treatment plants in recent years. Secondly, industrial application of ozone has also become very common, mainly used in the chemical, petroleum, paper, textile, pharmaceutical, and perfume industries. The application of food and food industry is more popular. In 1904, Europe used ozone to keep milk, meat, cheese, protein and other foods fresh. At the end of the 1930s, 80% of refrigerated egg warehouses in the United States installed ozone generators. After the Second World War, Europe, America, and Japan applied ozone to storage, manufacturing, and transportation in food, fruit, and vegetable preservation. In terms of medical treatment, Japan used ozone for physical therapy during World War II, and Russia used it for strong gas (ozonized air) sports applications. At present, there are many international medical applications such as air disinfection in wards and operating rooms, the use of ozone water for disinfection of medical equipment, the use of ozone for dental disease treatment (oral surgery and maintaining oral sterility), and the use of ozone and radiotherapy. Combined with the treatment of cancer, drinking ozone water to treat women‘s diseases, injecting ozone, hemorrhoids, varicose veins, etc. In terms of health care, it is popular in Japan and Taiwan to inhale strong air (air containing low concentrations of ozone) to strengthen the body, and to shower the body with ozone water to kill bacteria and beauty. Now the popular beauty is actually ozone.
1 The main functions of ozone
Sterilization: It can quickly and completely eliminate viruses and bacteria in the air and water. According to the experimental report of the academic unit, when the ozone concentration in the water is 0,05 ppm, after ten to ten minutes of treatment, the bacteria inactivation rate is over 99%.
Detoxification: Due to the development of industry and commerce and the enjoyment of high material civilization, life is full of various substances harmful to the human body: for example: carbon monoxide, pesticides, heavy metals, fertilizers, organics, odors, pigments, etc., after ozone treatment, they will It is decomposed into safe substances that are harmless to the human body.
Preservation: The United States, Japan and advanced European countries have applied ozone to the storage of various foods in large quantities, which can prolong the storage period of foods and reduce the rate of spoilage, so as to reduce losses and increase profits.
Bleaching: Because ozone has a strong oxidizing effect, it is a strong bleaching agent and can be used in laundry, food, and wastewater treatment.
Deodorization: Because ozone has a strong ability to oxidize and decompose, it can quickly and completely eliminate all kinds of peculiar smells in the air and water.
2 Application of ozone
At this stage, the application of ozone technology in various fields mainly includes the following aspects: ① Drinking water, industrial wastewater, domestic wastewater, swimming pool water treatment and hospital sewage treatment; ② Sterilization and medicine in the food industry and pharmaceutical industry. , Cleaning and disinfection of processing equipment and premises; ③,, fresh-keeping and transportation of vegetables and food; ④ ozone therapy and disease prevention in medicine; ⑤ ⑤ bleaching of hungry pulp and textiles in the chemical industry ⑥ in aquaculture. ⑦ Household air purification and disinfection, degradation of pesticide residues on the surface of vegetables and fruits; ⑧ Air disinfection, deodorization, deodorization, etc. of livestock and poultry breeding plants.
(1) Various public places
Using the strong oxidizing properties of ozone can remove toxic substances released by decoration, synthetic boards, and paints, inactivate bacteria and viruses in the air, inactivate microorganisms that breed in carpets, inactivate cold germs, and prevent the occurrence of influenza. Decomposition. Residual pesticides in vegetables and fruits. Improve the freshness of fish and meat, make it more durable, and preserve fruits and vegetables. Bathing with ozone water has the functions of bleaching, beauty and health care. Deodorize kitchen, bathroom, etc.
(2) Medical care
Ozone can be used to sterilize and disinfect the space air in medical places. Ozone water can sterilize the hands of doctors and nurses before surgery in the hospital. It can inactivate all bacteria. Not only is the time extremely short, its sterilizing power far exceeds that of chlorine. And water. Reliable safety.
Ozone also has the effect of curing certain diseases and beauty. For example, frequent ozone water washing and foot bathing can effectively treat and prevent athlete‘s foot, athlete‘s foot, and athlete‘s foot; frequent use of ozone water to wash the fungal infection of the skin area can receive a significant therapeutic effect; regular ozone water to wash the wound can prevent wound infection and promote its healing Wait.
(3) Application in the food industry
The purpose of applying ozone in the food processing industry is in four aspects: one is to inactivate microorganisms-sterilization and disinfection; the other is to oxidize and decompose organic or inorganic pollutants-deodorization and purification; the third is to decompose fruit and vegetable metabolites and inhibit the ripening process--preservation ; The fourth is to degrade pesticide residues in foods such as fruits, vegetables and so on. The application basis of the four aspects all depend on the strong oxidizing performance and unstable and easily decomposing characteristics of ozone. Specifically, it can be applied in the food processing industry. The application in the food and fruit preservation industry.
(4) In the livestock and poultry breeding industry
It can quickly inactivate various common bacteria, infectious viruses, fungi, mycoplasma, spirochetes and other pathogenic microorganisms in the indoor air of farms, and remove large amounts of ammonia, hydrogen sulfide, methane and other harmful gases and feces produced after fecal fermentation., Reduce livestock and poultry diseases, especially prevent the outbreak of epidemics in a large area, increase survival rate and output of livestock products, save labor and medicine costs, and improve the production environment on the farm. In the poultry industry, sterilization and preservation of breeding eggs can increase the rate.
(5) Application in water treatment
Can oxidize redundant or toxic inorganic substances, such as cyanide, etc., 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, inactivate viruses and bacteria in water, and produce clean disinfection water. It can be widely used in drinking water sterilization, reclaimed water purification, sewage treatment, greenhouse soil disinfection, swimming pool water treatment and hospital sewage treatment.
