The role of ozone

Ozone (chemical formula is O3), also known as active oxygen, trioxygen, superoxide, and rich oxygen, widely exists in the ozone layer 20 kilometers away from the earth's surface. It has attracted widespread attention because it can absorb most of the ultraviolet rays in solar radiation and protect life on earth from harm.

There is also a trace amount of ozone in the air (content is 0.01~0.04ppm), with the highest concentration in waterfall areas, seaside, and forest areas. In general, the ozone concentration in forest areas can reach 0.1ppm. It is produced by ultraviolet rays from sunlight. After being concentrated by small water droplets, the oxygen in the water droplets reacts into ozone. Especially when it rains and thunders, lightning will produce a large amount of ozone. These trace amounts of ozone in the air effectively inhibit the abnormal reproduction of bacteria and mold in nature and maintain ecological balance.

In 1785, when the Germans were using electric motors, they discovered that a peculiar smell was produced when the motor discharged. In 1840, German scientist Schonbein identified the odor as O3 and named it OZONE. Since then, European scientists have taken the lead in studying the characteristics and functions of ozone. After discovering its broad-spectrum sterilization effect, they began to apply it in industrial production. Among them, a Swedish beef company used ozone to preserve the freshness of beef storage. Since 1870, it has been Still in use today.

In the 19th century, people recognized the strong oxidizing effect of ozone and found that ozone has an oxidizing effect on wood, straw, starch, plant pigments, natural rubber, fats, animal and vegetable oils, alcohol and other substances. In 1868, de Gebeth obtained the first patent for ozone application technology, using ozone to oxidize coal tar mixture into products suitable for coatings and paints. In 1873, Europe put ozone into use in sugar refining and flax bleaching. For more than 100 years, ozone applications have penetrated into many fields and made significant contributions to the development of human production technology. Ozone applications are divided into four fields according to their uses: water quality treatment, chemical oxidation, food processing and preservation, and medical treatment. Application research and equipment development in each field have reached a very high level. The world has formed an independent ozone technology industry and sector. The International Ozone Association (IOA) established in 1973 is located in Canada. The association holds an international conference every two years to exchange papers and reports on ozone technology development in various countries. Developed countries have generally established IOA regional organizations to conduct academic exchanges.

After World War II, ozone application technology has made great progress internationally. First, in 1902, Paderborn, Germany built the first large-scale water plant that used ozone to treat water quality, pioneering ozone water treatment. There are now thousands of ozone water plants in the world. The application of ozone in water plants in Europe, the United States, Japan, Canada and other countries has reached a popular level. The tap water that uses ozone to replace chlorine disinfection and purification can be used for direct drinking. Almost all mineral water and purified water manufacturers are equipped with ozone equipment. The United States began to use ozone to treat domestic sewage in the early 1970s, mainly for sterilization, removal of pollutants, decolorization, etc. to meet emission standards. Japan treats sewage with ozone and uses it as reclaimed water in water-scarce areas. The United States, Japan, Germany, France and other countries have all established large-scale ozone sewage treatment plants in recent years. Secondly, industrial application of ozone has also become very common, mainly used in chemical, petroleum, papermaking, textile and pharmaceutical, and spice industries. The application in the food industry has become more popular. In 1904, ozone was used in Europe to preserve milk, meat products, cheese, protein and other foods. By the end of the 1930s, 80% of refrigerated egg warehouses in the United States were equipped with ozone generators. After World War II, Europe, the United States, and Japan applied ozone to all aspects of storage, manufacturing, and transportation in the preservation of food, fruits, and vegetables. In terms of medical treatment, Japan used ozone for human physical therapy during World War II, and Russia used strong gas (ozonated air) to strengthen the physique of sports athletes. At present, there are many uses in the medical field internationally: such as air disinfection in wards and operating rooms, the use of ozone water for disinfection of medical instruments, the use of ozone for dental disease treatment (oral surgery and maintaining oral sterility), the use of ozone and radiation Physiotherapy is combined to treat cancer, drinking ozone water treats women's diseases, and injecting ozone gas treats fistulas, 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 use ozone water to shower the body to kill bacteria and beautify the body. The popular high-tech beauty treatment nowadays is actually the application of ozone beauty treatment. Major international competition swimming pools and diving pools also use ozone sterilization and disinfection to protect the health of athletes.

Scientific research has found that ozone molecules are extremely unstable and can decompose to produce single-atom oxygen (O) and hydroxyl (OH) with extremely strong oxidizing power, which can quickly destroy the internal structure of bacteria, viruses and other microorganisms, and are harmful to all kinds of organisms. Pathogenic microorganisms have a strong killing effect! The sterilization effect of ozone is much better than that of chlorine. The sterilization speed is more than 200 to 3000 times faster than that of chlorine. It can self-decompose into oxygen and will not leave harmful substances behind and cause secondary pollution.

The representative field of ozone technology industrialization is drinking water treatment engineering. Especially after the 1970s, after the carcinogenic effects of halogenated organic compounds were confirmed, all countries have strictly restricted the use and emission of chlorine. Ozone technology has become the preferred technology in developed countries to replace chlorine in drinking water treatment projects. More than 10,000 ozone water plants have been put into operation in the world, and they have reached a level of popularity in Europe. The United States, Canada, Japan and other countries are vigorously developing ozone treatment drinking water projects. For example, the United States uses ozone technology for water purification projects. Thousands of large-scale water plants use ozone for disinfection to popularize cancer-free drinking water for its citizens. The United States also uses ozone to purify surrounding sea areas. In the early 1990s, the world-wide shrimp epidemic Amid the epidemic, the United States has stood out and reaped bumper harvests and rewards. Bottled drinking water in European and American countries has become completely popular using ozone sterilization and purification process. In my country, Beijing, Shanghai, Fushun and other places also established several ozone treatment water plants in the 1980s and 1990s, with Beijing Tiancun Water Plant being the largest. Some large enterprises in my country are actively adopting ozone disinfection technology in their self-water supply plants, such as Daqing, Shengli Oilfield, Yanshan Petrochemical and other ozone water plants in operation. In the bottled drinking water industry that has emerged in my country in recent years, the use of ozone sterilization and purification projects is the most common, and has been recognized by technical supervision and health and epidemic prevention departments. Bottled water plants without ozone equipment are difficult to compete in the market.

In the late 1990s, the United Nations repeatedly included protecting the ozone layer and improving the human living environment on the agenda of the United Nations General Assembly, and formulated corresponding international conventions requiring ozone to be used as an important substance for environmental protection and publicity. It became a household name and everyone knew it. Therefore, the status of ozone as an environmental protection industry has been unprecedentedly improved, and its technological development and industrial process have a good social foundation.

The mechanism and characteristics of ozone disinfection

1. The mechanism of ozone disinfection

Ozone is the second strongest oxidant known to mankind after fluorine. Ozone At a certain concentration, it can produce biochemical oxidation reactions with microorganisms such as bacteria and viruses. Ozone has high energy, so it is unstable. Its molecular structure is easily changeable at normal temperature and pressure, and it quickly decomposes into oxygen (O2) and a single oxygen atom (O). Single oxygen (O) has strong activity and has a strong oxidizing effect on microorganisms such as bacteria, viruses and heavy metals.

Ozone can oxidize and decompose the glucose oxidase necessary for oxidizing glucose within bacteria, and directly interacts with bacteria and viruses, destroying their organelles and ribonucleic acid, and decomposing DNA, RNA, proteins, lipids and polysaccharides. Such macromolecular polymers cause damage to the bacterial material metabolism, growth and reproduction process. It can also penetrate the cell membrane tissue, invade the cell membrane, act on the outer membrane lipoproteins and internal lipopolysaccharides, cause permeability distortion of the cells, lead to cell dissolution and death, and remove the genes, parasitic strains, and parasites in the dead bacteria. Virus particles, phages, mycoplasmas and pyrogens (endotoxin) dissolve, degenerate and die. Overall, the principles of aseptic technology's effect on microorganisms can be divided into three types: bacteriostatic, bactericidal and bacteriolytic. Ozone sterilization is a bacteriolytic agent that can "completely and permanently eliminate all microorganisms inside the object."

2. Characteristics of ozone disinfection

Ozone disinfection and sterilization method has the following characteristics compared with conventional disinfection and sterilization methods.

(1) High efficiency Ozone disinfection uses air as the medium and does not require any other auxiliary materials and additives. A certain amount of ozone is generated during disinfection. In a relatively sealed environment, it spreads evenly and has good tolerance. It overcomes the many dead ends of ultraviolet sterilization and can achieve all-round, fast and efficient disinfection and sterilization purposes. In addition, it has a wide sterilization spectrum and can kill bacterial propagules, spores, hepatitis A and B viruses, various pneumonia viruses, fungi, protozoal cells and other viruses. It can also destroy botulinum toxins and rickets. It also has a strong function of removing mold, fishy, ??smelly and other odors.

(2) High cleanliness The characteristic of ozone quickly and naturally decomposing into oxygen is the unique advantage of ozone as a disinfectant and sterilizer.

Ozone is produced by using oxygen in the air. During the disinfection and oxidation process, excess oxygen (O) is combined into oxygen molecules (O2) after 30 minutes without any residue. This solves the problem of secondary pollution caused by disinfectants. At the same time, It saves you the trouble of cleaning again after disinfection.

(3) Convenience Ozone sterilizers are generally installed in clean rooms or air purification systems or sterilization equipment (such as ozone sterilization cabinets, transfer windows, etc.). Set the opening and running time of the sterilizer according to the sterilization concentration and time verified by debugging, which is easy to operate. Ozone disinfection can be started and used regularly every day.

(4) Economy: Judging from the use of ozone disinfection and sterilization in many pharmaceutical industries and medical and health units, the ozone disinfection method has great economic and social benefits compared with other methods. In today's rapid industrial development, environmental protection issues are particularly important, but ozone disinfection avoids the secondary pollution problems caused by other disinfection methods, providing a one-time investment and permanent benefits.

Applications of air disinfection and sterilization

1. Home The air in the home is more polluted than outdoors, but there are currently no effective products to solve this problem. Since home decoration and air conditioning installation have become very popular, the environment that is warm in winter and cool in summer and the improvement of sealing have created conditions for bacterial reproduction. Moreover, post-decoration air pollution, water heater (gas), gas stove pollution, the elderly Or the odor emitted by patients, the odor in the bathroom, smoking, the respiratory metabolism of family members, the visits of guests, etc., all bring pollution to the air in the home. Therefore, it is very necessary to use ozone for air purification in the home.

2. Industrial sites Food, fruit and vegetable industry processing workshops, pharmaceutical processing workshops, etc. These manufacturing sites that are closely related to human life require disinfection and sterilization methods. They are an extremely broad ozone application market. In addition, ozone can also remove air pollution in printing and chemical workshops, the fishy smell of fish products, and the odor of breeding plants. It can also be used for the prevention and health care of breeding poultry (chicks). It is used for air disinfection in vegetable greenhouses and can replace pesticides.

3. Food Preservation The use of ozone to preserve food, fruits, vegetables, etc. is very popular in Europe, America, Japan and other countries. It has penetrated into all aspects of production, storage, and transportation, which is still rare in our country. Ozone is used for preservation. Its main application markets are cold storage, constant temperature warehouses, ships, and transportation vehicles. It can prevent meat products from deteriorating for a long time; it can also keep fruits and vegetables intact during their storage period, and it is good for strawberries, Berries such as cherries and grapes can also enhance their aroma on the basis of preservation. Their biggest advantage is that they can store the inventory under high humidity conditions with less weight loss and high storage quality.

4. Public places such as stock trading halls, conference halls, waiting rooms, hotels, dance halls, nightclubs, guesthouses, etc., where the mobility of people is high, in addition to polluted air, there is also the risk of viruses and bacteria Cross-infection poses a direct threat to people's health, especially hepatitis B virus, cold virus and various types of pneumonia that make people talk about it. However, these places currently do not have effective disinfection and sterilization methods, and the use of ozone products is The market demand potential is huge.

5. Hospitals are places where patients gather. The occurrence and spread of viruses and bacteria are relatively serious. In order to ensure the recovery of patients and avoid cross-infection, hospitals have very strict disinfection and sterilization procedures and systems. . At present, the main methods of disinfection and sterilization in hospitals are:

(1) Ultraviolet sterilization is often used for room air disinfection. The disadvantages of ultraviolet sterilization are slow sterilization speed, high cost, and dead ends. Ultraviolet rays can cause damage to human skin. The requirements are very strict;

(2) Potassium permanganate, peracetic acid solution and burning, steaming, boiling and other methods are often used for disinfection of medical equipment; the disinfection of equipment and supplies involves secondary contamination during the storage process. , affecting the service life and other issues.

(3) Large-scale massacres are often carried out with Lysol, which gives the hospital a special and unpleasant smell.

(4) The use of ozone products has the advantages of rapid, thorough, odorless, no side effects, convenience, and low cost.

Applications in water treatment

1. Drinking water treatment

The most extensive and successful field of ozone application technology is the treatment of drinking water.

At present, water pollution in our country mainly comes from industrial wastewater, pesticides and fertilizers, domestic wastewater, corrosion of water pipeline networks and suspended solids, microorganisms, bacteria, viruses, algae, etc. in high-rise secondary water supply.

The water we ultimately drink cannot meet the national standard (GB5749). Items that often exceed the standard include: total number of bacteria, E. coli, iron, manganese, heavy metals, chloroform, algae substances, color, turbidity, etc. Even if it is qualified, there are still secondary pollution problems such as rust in water pipes and bacteria in water tanks. Boiling raw water can only partially sterilize it. Chlorination and chlorine dioxide and sodium hypochlorite disinfection have been promoted in recent years, and the tap water provided cannot be drank directly. Because chlorine disinfection will produce chlorine derivatives, causing secondary pollution, trihalomethanes are direct carcinogens and have been gradually phased out in drinking water treatment in Europe and the United States. Therefore, in 1996, the Ministry of Health of the People’s Republic of China issued a document requiring the installation of disinfection facilities for secondary water supply. Some units’ self-provided wells must also be used when the water quality reaches standards. Disinfection and treatment products for secondary water supply are currently only available in secondary water supply. Selected among chlorine oxide, sodium hypochlorite and ozone generating equipment, ozone water treatment has obvious competitive advantages. Various household water purifiers and purified water that are currently popular on the market only filter particles and impurities in the water, but cannot completely disinfect them. Moreover, while filtering impurities, they also filter out organic substances necessary for the human body such as calcium, iron, Zinc, etc., drinking this kind of soft water for a long time will be harmful to the human body without any benefit.

2. Swimming pool water treatment

Ozone technology is very mature for swimming water treatment and is widely used in Europe and the United States. Almost all swimming pools in international competitions are treated with ozone technology. my country's swimming water standards require the number of bacteria to be less than 1,000, coliforms to be less than 100, and turbidity to be less than 5. Due to technical and economic reasons, chlorine, bleaching powder, copper sulfate and other disinfection methods are currently mainly used. While the water quality meets the standards, it also causes adverse reactions such as eye-catching water and skin irritation. In particular, the potential threat of liquid chlorine is very great. Once leaked, it will cause poisoning and pollution in a large area, making people worried when using it. Ozone technology does not have the above defects at all when the water quality reaches the standard.

3. Aquaculture water treatment

Aquaculture water is rich in organic matter, and water quality is prone to problems. Bacteria and viruses are very harmful to fish and shrimps. In recent years, many coastal areas in my country have Breeding plants have lost production, reduced production, and been abandoned in large numbers, making the development of the artificial breeding industry difficult. In aquaculture water treatment, ozone can not only sterilize and inhibit the infection and spread of viruses to fish and shrimp, but also degrade organic matter, reduce chemical oxygen demand (COD) and biochemical oxygen demand (BOD), and because of its coagulation-assisting effect, Can improve water quality. According to foreign reports, using ozone to treat aquaculture water can increase fish production by more than 30% and shrimp production by more than 60%. Comparative experiments on fish, shrimp, and crab seedlings have increased the survival rate by more than 90%. Ozone is used in breeding water. Generally, ozone concentration of 0.5-1.2mg/L can kill all bacteria in the water that cause harmful viruses and bacteria, and 0.5-0.7mg/L can be used as a preventive measure. Because of its significant economic benefits, ozonation has been widely used in Europe and the United States to treat aquaculture water. In recent years, due to the rapid economic development in my country and the relative lag in environmental governance, environmental pollution has intensified, and water pollution has become increasingly serious. It is not uncommon for polluted water to cause large numbers of fish deaths. In the context of large investment in environmental management and slow results, promoting ozone water treatment projects in the breeding industry on a large scale and in large areas can achieve both economic and social benefits.

In addition, the application technology of ozone technology products in circulating water, industrial wastewater, domestic sewage treatment, etc. is also relatively mature and has significant effects. In the current situation of water resource shortage, it is important to improve water utilization. Saving water is of great significance.

Applications in daily life

1. Ozone is one of the strongest oxidants known to be available. In actual use, ozone has outstanding sterilization, disinfection and degradation of pesticides. It is an efficient broad-spectrum fungicide. Ozone can oxidize and denature the protein shells of bacteria, fungi and other cells, and can kill bacterial propagules and spores, viruses, fungi, etc. Common E. coli, faecal Streptococcus, Staphylococcus aureus, etc., the killing rate is over 99%. Ozone can also kill bacterium viruses, cold viruses, etc. Ozone diffuses quickly and evenly in the indoor air, disinfecting without dead ends.

2. Ozone only kills viruses and bacteria and is harmless to healthy cells because healthy cells have a powerful balanced enzyme system.

3. Ozone can sterilize and purify the air, prevent cross-infection of diseases, and remove odors in bedrooms, living rooms, kitchens, bathrooms, etc.

Ozone gas has the effects of sterilizing, disinfecting, preventing mildew, and removing dust mites on indoor bedding, clothing, carpets, wardrobes, shoe cabinets, coins, etc.

4. Some areas in my country have short sunshine hours, high humidity, and serious air pollution, which further demonstrates the special effects of ozone.

5. The most suitable way to use ozone is to dissolve ozone in water to form so-called "ozone water". Some developed countries in Europe and the United States call "ozone water" "universal water". Its sterilization speed is more than a thousand times higher than that of chlorine.

6. Ozone water can disinfect and sterilize underwear, panties, diapers, quilts, etc. used by women and children.

7. Ozone water can sterilize fruits, vegetables, and meat, preserve freshness, and eliminate odors. At the same time, it has the function of degrading phosphorus-containing pesticides remaining on the surface of fruits and vegetables, and can extend the shelf life of food.

8. Ozone water can clean the skin, maintain the skin, and reduce the irritation of cosmetics on the skin. Using ozone water to apply cold compresses and soak burns, cuts, and bruises can speed up wound healing and prevent infection.

9. Ozone products can be widely used in: homes, hospitals, hotels, restaurants, beauty salons, public toilets, food processing industry, schools, kindergartens, nursing homes, finance, securities, offices, Entertainment venues, military, industry, agriculture, fishery, aquaculture and environmental protection and other fields.

10. The role of ozone therapy in the human body

(1) Deactivating bacteria, viruses, etc. Ozone can destroy the integrity of cell membranes, thereby entering cells and making them inactive. And remove them from the body and replace them with healthy cells.

(2) Promote circulation For circulatory system diseases, ozone can reduce or remove the clumping of red blood cells in the blood, restore their elasticity, so that they can pass through capillaries and enhance the absorption of oxygen. At the same time, it can also increase arterial pressure, reduce blood viscosity, and promote blood circulation. Ozone's oxidation of platelets can also remove waste and unblock blood vessels.

(3) Promote oxygen metabolism. Ozone can promote the rate of glycolysis in red blood cells and promote the release of oxygen in human tissues. It can also stimulate free radical scavengers, enzymes produced by some protective enzymes. Accelerate Kreb's cycle and increase ATP production. NaOH can also increase the production of a vasodilator.

(4) Formation of peroxidase Ozone reacts with unsaturated fatty acids to generate hydrogen peroxide. Lipid peroxidation products include: alkoxy groups, peroxy groups, singlets, ozonides, and carbides. , alkanes and dilute hydrocarbons, etc.

(5) Decomposition of malignant tumors. Ozone can inhibit the growth of tumors. In addition, ozone can also oxidize the lipid layer of malignant cells, and phagocytes produce H2O2 and carboxyl groups to kill bacteria and viruses. The principle is that ozone converts L-arginine into ornithine. Nitrite and Nitrate.

(6) Parallel treatment Ozone is not a medicine, nor is it magic. It is just an effective treatment method to restore the human body to health. What really works is the body's immune system.

Ozone (chemical formula is O3), also known as active oxygen, trioxygen, superoxide, and rich oxygen, widely exists in the ozone layer 20 kilometers away from the earth's surface because it can absorb most of the solar radiation. Some ultraviolet rays protect the earth's creatures from harm and are widely concerned by the world.

There is also a trace amount of ozone in the air (content is 0.01~0.04ppm), with the highest concentration in waterfall areas, seaside, and forest areas. In general, the ozone concentration in forest areas can reach 0.1ppm. It is produced by ultraviolet rays from sunlight.
