Ozone (chemical molecular formula for O3), also known as live oxygen, triple oxygen, super-oxygen, oxygen-rich, widely present in the ozone layer 20 kilometers away from the earth's surface, because it can absorb most of the ultraviolet radiation from solar radiation, to protect the earth's living creatures from harm, and is widely concerned about the world.
Traces of ozone also exist in the air (content of 0.01 to 0.04 ppm), waterfall areas, seashores, forest areas with the highest content, the general concentration of ozone in forested areas can reach 0.1 ppm, generated by ultraviolet rays of the sun's rays are concentrated by a small droplet of water after the reaction of the oxygen within the droplet into ozone. Especially when it rains and thunders, lightning produces large amounts of ozone. These trace amounts of ozone in the air effectively inhibit the abnormal reproduction of bacteria and molds in nature and maintain ecological balance.
In 1785, the Germans found a strange odor in the motor discharge when using the motor, and in 1840, the German scientist Schonbein identified this odor as O3 and named it OZONE (ozone). Since then, European scientists took the lead in the study of the characteristics and utility of ozone, found that the broad-spectrum sterilization effect, began industrial production applications, including a Swedish beef company used ozone for beef storage of freshness, since 1870, has been used to date.
In the 19th century, people recognized the strong oxidizing effect of ozone, found that ozone on wood, straw, starch, plant pigments, natural rubber, fats, animal and vegetable oils and alcohols, and other substances have an oxidizing effect. 1868, de? Gebeth (de? Gebeth) obtained the first patent for ozone application technology, with ozone will be oxidized coal tar mixture for coatings, paints, the use of products. 1873, Europe will be ozone in the sugar refining and flax bleaching put into use. More than a hundred years ozone application has been deep into a number of fields, the human production technology development has made significant contributions. Ozone applications are divided into four areas according to the use of water treatment, chemical oxidation, food processing and medical four areas of freshness, each area of applied research and equipment development has reached a fairly high level. The world has formed an independent ozone technology industry and sector, established in 1973, the International Ozone Association (IOA) based in Canada. The Association held every two years an international conference to exchange papers and reports on the development of ozone technology in various countries, developed countries are generally established IOA regional organizations for academic exchanges.
After World War II, the international ozone application technology has been a great development. First of all, in 1902, Germany, Paderborn established the first large-scale water treatment with ozone water treatment plant, creating a precedent for ozone water treatment, and now there are thousands of ozone water plants in the world. Europe and the United States, Japan, Canada and other countries in the application of ozone in the water plant has reached a popular degree, the use of ozone instead of chlorine disinfection and purification of tap water for direct drinking. Mineral water, pure water manufacturers are almost all equipped with ozone equipment. The United States in the early seventies began to use ozone to deal with domestic sewage, mainly for sterilization and disinfection, removal of pollutants, decolorization, etc. to meet the discharge standards. Japan will be in water-scarce areas with ozone treatment of sewage as water use. The United States, Japan, Germany, France and other countries in recent years have established large-scale ozone sewage treatment plants. Secondly, the industrial application of ozone has also been very common, mainly used in chemical, petroleum, paper, textile and pharmaceutical, spice industry. The application of the food industry is more popular, in 1904 Europe on the use of ozone to preserve milk, meat products, cheese, egg white and other food preservation treatment, the end of the thirties, the United States, 80% of the refrigerated egg banks are installed ozone generators. After World War II, Europe and the United States, Japan in the preservation of food fruits and vegetables will be the use of ozone to storage, manufacturing, transportation and other aspects. In terms of medical care, World War II, Japan will use ozone for human physiotherapy, Russia is a strong gas (ozonized air) to strengthen the physical fitness of sports athletes. At present, the international medical aspects of a variety of uses: such as wards, operating room air disinfection, the use of ozone water for the disinfection of medical instruments, the use of ozone for the treatment of dental diseases (oral surgery and to maintain the oral cavity sterile), the use of ozone and radiotherapy combined with the treatment of cancer, drinking ozone water treatment of women's diseases, injection of ozone gas treatment of fistulae hemorrhoids, varicose veins and so on. In health care, Japan, Taiwan popular inhalation of strong gas (containing a low concentration of ozone air) to strengthen the body, with ozone water shower body to kill bacteria and beauty. Now popular high-tech beauty, in fact, is the application of ozone beauty. And major international competitions, swimming pools, diving pools also use ozone sterilization to protect the health of athletes.
Scientific research has found that the ozone molecule is extremely unstable, can be decomposed to produce a strong oxidizing capacity of the single atom of oxygen (O) and hydroxyl (OH), rapid destruction of bacteria, viruses and other microorganisms of the internal structure of a variety of disease-causing microorganisms have a very strong killing effect! Ozone sterilization effect is much better than chlorine, sterilization faster than chlorine 200 to 3000 times faster than the ability to self-decomposition into oxygen, will not remain harmful and cause secondary pollution.
The industrialization of ozone technology on behalf of the field of drinking water treatment works. Especially in the 1970s, after the carcinogenic effect of halogenated organic compounds have been confirmed, countries are strictly limited to the use of chlorine and emissions, ozone technology to deal with drinking water projects, has become a developed country alternative to chlorine to deal with drinking water projects, the technology of choice, so far more than 10,000 ozone plants in the world have been put into operation, has reached a degree of popularity in Europe, the United States, Canada, Japan and other countries are vigorously develop the application of ozone Drinking water treatment project. Such as the United States will ozone technology for water purification projects, large-scale thousands of water plants, with ozone disinfection, to popularize the national cancer-free drinking water, the United States also use ozone to purify the surrounding waters, in the early 1990s the world's shrimp plague, the United States stands alone, and gained a bumper harvest and returns. Europe and the United States bottled drinking water, the use of ozone sterilization purification process has been completely popularized. China's Beijing, Shanghai, Fushun and other places in the eighties and nineties also established a few ozone treatment of water treatment plants to Beijing Tiancun water plant is the largest. Some of China's large-scale enterprises from the water supply plant using ozone sterilization process is more active, such as Daqing, Shengli Oilfield, Yanshan Petrochemical and other ozone water plant are in operation. China's bottled drinking water industry in recent years, the use of ozone sterilization and purification project is most common, and has been recognized by the technical supervision, health and epidemic prevention departments, there is no ozone equipment bottled water plant is difficult to compete in the market.
The late nineties of the twentieth century, the United Nations has repeatedly to protect the ozone layer, improve the living environment of mankind on the agenda of the United Nations General Assembly, and the development of the corresponding international conventions, the requirements of the ozone as the protection of the environment as an important substance, publicity to the household, everyone knows. Therefore, the status of ozone as an environmental protection industry has been unprecedentedly improved, and its technological development and industrial process has a good social foundation.
Ozone disinfection mechanism and characteristics
One, ozone disinfection mechanism
Ozone is known to mankind after fluorine, the second strongest oxidant, ozone in a certain concentration with bacteria, viruses and other microorganisms to produce biochemical oxidation reactions. Ozone has a very high energy, so it is not stable, the molecular structure is easy to change at room temperature, normal pressure, and soon decompose itself into oxygen (O2) and a single oxygen atom (O). Single oxygen (O) has a strong activity, bacteria, viruses and heavy metals and other microorganisms have a strong oxidizing effect.
Ozone can oxidize and decompose the glucose oxidase necessary to oxidize glucose within the bacteria, and directly interact with bacteria, viruses, destroying their organelles and ribonucleic acid, decomposition of DNA, RNA, proteins, lipids, and polysaccharides and other macromolecules, so that the bacterial material metabolism of the growth and reproduction process meets with destruction. Can also penetrate the cell membrane organization, invade the cell membrane, the role of the outer membrane lipoproteins and internal lipopolysaccharide, so that the cell permeability aberration, resulting in cell lysis and death, and the death of bacteria in the body of the genetic, parasitic strains, parasitic viral particles, phage, mycoplasma and pyrogens (endotoxin), such as the death of the dissolution of the denaturation. To summarize the principle of aseptic technology on the role of microorganisms can be divided into three kinds of bacteriostatic, bactericidal and bacteriolytic. Ozone sterilization disinfection belongs to the bacteriostatic agent, can "completely and permanently destroy all the microorganisms inside the object".
Two, ozone disinfection characteristics
Ozone disinfection and sterilization methods compared with conventional disinfection and sterilization methods have the following characteristics.
(1) high efficiency Ozone disinfection is the air as a medium, without any other auxiliary materials and additives. Disinfection occurs when a certain amount of ozone, in a relatively sealed environment, diffusion uniformity, inclusive and good, overcoming the characteristics of ultraviolet sterilization of the existence of a number of dead ends, can achieve a full range of rapid and efficient disinfection sterilization purposes. In addition, it has a wide sterilization spectrum, which can kill bacterial propagules, germ cells, hepatitis A and B viruses, various types of pneumonia viruses, fungi and protozoa cytosol and other viruses, but also can destroy botulism and toxins and rickettsiae, etc., and also has a strong mold, fishy, smelly odor removal function.
(2) high cleanliness The rapid and natural decomposition of ozone into oxygen is a unique advantage of ozone as a disinfectant and sterilizer. Ozone is generated using oxygen in the air, disinfection and oxidation process, excess oxygen (O) in 30min and then combined into oxygen molecules (O2), there is no residue, solving the problem of disinfectants are prone to secondary pollution, while eliminating the need to clean again after the end of disinfection.
(3) Convenience The ozone sterilizer is generally installed in the clean room or air purification system or sterilization equipment (such as ozone sterilizing cabinet, transfer window, etc.). According to the debugging verification of the sterilization concentration and time to set up the sterilizer to open and run time, easy to operate and use. And ozone sterilization can be turned on every day at regular intervals.
(4) Economy: Through the use of ozone sterilization in many pharmaceutical industries and health care units, ozone disinfection method compared with other methods have great economic and social benefits. In today's rapid industrial development, environmental issues are particularly important, and ozone disinfection to avoid the problem of secondary pollution generated by other disinfection methods, an investment, permanent income.
Air disinfection and sterilization applications
One, the family The air in the living room is more polluted than outdoor serious, and there is no effective product to solve this problem. As the family room decoration and air-conditioning installation has been very popular, warm in winter and cool in summer environment and sealing the degree of improvement, have created conditions for bacterial reproduction, and after the decoration of air pollution, water heaters (gas), gas cooker pollution, the elderly or the patient exudes odor, bathroom odor, smoking, family members of the respiratory metabolism, the guest's visit, etc., have brought to the family's air pollution, so the family used ozone For air purification is very necessary.
Two, industrial places Food and fruit and vegetable industry processing plant, pharmaceutical processing plant, etc., these and human life are closely related to the manufacture of places, disinfection and sterilization means is necessary, is an extremely vast ozone application market. In addition, ozone can also remove the printing, chemical workshop air pollution, fish products, as well as the fishy odor of the breeding plant odor. Can also be used for breeding poultry (chicks) of the anti-plague health care. Used in vegetable greenhouse air disinfection and can replace pesticides.
Three, food preservation Ozone for food, fruit, vegetables and other freshness in Europe and the United States, Japan and other countries is very popular, has been infiltrated into the production, storage, transportation of all aspects of our country is still rare. Ozone is used for preservation, its main application market is cold storage, thermostatic storage, ships, transport vehicles, it can make meat food in a very long time does not deteriorate; also can make fruit, vegetables in the preservation of the period intact as the beginning of strawberries, cherries, grapes, and other berries can be enhanced in the preservation of freshness on the basis of the aroma, the greatest superiority of its inventory can be stored in high humidity conditions, weight loss is less, the quality of storage is high.
Four, public **** places Stock exchange halls, conference halls, waiting (machine) room, hotels, dance halls, nightclubs, hotels, etc., the mobility of people, in addition to air pollution, cross-infection of viruses and bacteria on the people's health a direct threat, especially Hepatitis B virus, cold viruses, as well as talk about all kinds of pneumonia and so on, so that people can not prevent, and these places are not effective means of disinfection, disinfection and sterilization of ozone products. Sterilization means of disinfection, the market demand for ozone products has great potential.
Fifth, hospitals Hospitals are places where patients gather, viruses, bacteria and the spread of more serious, hospitals in order to ensure the recovery of patients and to avoid cross-infection, there are very strict disinfection and sterilization procedures and systems. At present, the hospital disinfection and sterilization means are:
(1) room air disinfection with ultraviolet sterilization ultraviolet sterilization shortcomings are slow sterilization, high cost, there is a dead zone, ultraviolet light on the human skin can constitute an injury, the use of the requirements are very strict;
(2) medical equipment disinfection with potassium permanganate, peroxyacetic acid solution and burning, steaming, boiling and other means; instrumentation supplies Sterilization of instruments and supplies in the storage process of secondary pollution, affecting the use of life and other issues.
(3) The means of killing large areas of the general use of Lysol splashing, so that the hospital has a special unpleasant odor.
(4) the use of ozone products with rapid, thorough, odorless, no side effects, convenient, low-cost advantages.
Water treatment applications
I. Drinking water treatment
Ozone application technology is the most widely used, the most successful area is the treatment of drinking water.
At present, our country's water pollution mainly comes from industrial wastewater, pesticides and fertilizers, domestic wastewater, water pipeline network rust and high-level secondary water supply in the suspended solids, microorganisms, bacteria and viruses, algae and so on. So that we end up drinking water does not meet the national standard (GB5749), often exceed the standard items are: total bacteria, E. coli, iron, manganese, heavy metals, chloroform, algal substances, chromaticity, turbidity and so on. Even if qualified, there are still water pipe rust, water tank bacteria and other secondary pollution problems. Boiling raw water can only partially sterilize. Chlorination and in recent years the promotion of chlorine dioxide and sodium hypochlorite disinfection, the tap water can not be directly consumed. Because chlorine disinfection will produce chlorine derivatives, resulting in secondary pollution, of which trihalomethanes are direct carcinogens, in Europe and the United States on the treatment of drinking water has been phased out. Therefore, in 1996, the State Ministry of Health issued a document requiring the secondary water supply must be installed disinfection facilities, some units of the well must also be in the case of water quality standards before allowing the use of secondary water supply disinfection and treatment products, currently only in chlorine dioxide, sodium hypochlorite and ozone generating equipment in the selection, ozone water treatment has obvious competitive advantages. Currently more popular on the market a variety of household water purifiers and pure water, just filter the particles and impurities in the water, and can not be completely disinfected, but also in the filtration of impurities at the same time, but also filtered out the human body essential organic matter such as calcium, iron, zinc, etc., long-term drinking of this soft water in the human body has a lot of harm but no good.
Two, swimming pool water treatment
Ozone technology for swimming water treatment technology has been very mature, Europe and the United States and other countries are very common, the international competition swimming pools are almost all ozone technology. China's swimming water standards require the number of bacteria <1000, coliform <100, turbidity <5, due to technical, economic and other reasons, the current main use of chlorine, bleach, copper sulfate and other means of elimination, in the water quality to meet the standards at the same time, but also cause the water quality of the eye, irritation of the skin, and other adverse reactions, especially the use of liquid chlorine in the potential threat is very large, once the leakage will cause large-scale poisoning contamination, the use of which is fearful. The use of fear. Ozone technology in the case of water quality standards are completely free of the above defects.
Three, aquaculture water treatment
Farming water is rich in organic matter, water quality is prone to problems, bacteria, viruses on fish and shrimp is very serious, in recent years, many of our country's coastal aquaculture plant extinction, production, a large number of deserted, resulting in the development of artificial aquaculture industry is struggling. Ozone in aquaculture water treatment, in addition to sterilization and inhibit the infection of viruses on fish and shrimp, transmission, but also can degrade organic matter, reduce chemical oxygen demand (COD) and biochemical oxygen demand (BOD), but also because of its coagulation effect, you can improve the water quality. Foreign reports, with ozone treatment of aquaculture water, fish can increase production by more than 30%, shrimp can increase production by more than 60% of the fish, shrimp, crab fry comparison experiments, the survival rate are increased by more than 90%. The use of ozone in aquaculture water, generally causing harm to viruses and bacteria, ozone concentration of 0.5-1.2mg/L can all kill bacteria in the water, 0.5-0.7mg/L can be used as a preventive. Because of its significant economic benefits, in Europe and the United States has been widely used ozonation treatment of aquaculture water. China in recent years due to rapid economic development, environmental governance work is relatively lagging behind caused by increased environmental pollution, water pollution is becoming increasingly serious, polluted water caused by a large number of fish deaths are common. In the case of environmental governance investment, slow results, a wide range of large-scale promotion of ozone water treatment works in the aquaculture industry, can achieve economic and social benefits.
In addition, ozone technology products in the recycled water, industrial wastewater, sewage treatment and other aspects of the application of technology is also relatively mature, the effect is significant, in the current situation of water scarcity, to improve water utilization, water conservation is very significant.
Applications in daily life
I. Ozone is one of the strongest oxidizing agents known to be available, and in practical use, ozone has an outstanding bactericidal, disinfectant, pesticide degradation, and is a highly effective broad-spectrum bactericide. Ozone can oxidize and denature the protein shells of bacteria, fungi and other organisms, and can kill bacterial propagules and germ cells, viruses, fungi and so on. Common E. coli, fecal streptococcus, Staphylococcus aureus, etc., the killing rate is more than 99%. Ozone can also kill bacillus viruses, cold viruses, etc., ozone in the indoor air diffusion fast and uniform, disinfection without dead ends.
Two, ozone only kills viruses and bacteria, harmless to healthy cells, because healthy cells have a strong balance of enzyme system.
Three, ozone can sterilize and purify the air, prevent cross-infection of diseases, and remove odors from bedrooms, living rooms, kitchens and bathrooms. Ozone gas is effective in sterilizing, disinfecting, preventing mildew and removing dust mites on indoor bedding, clothes, carpets, closets, shoe cabinets, coins and so on.
Four, some areas of China's short sunshine hours, high humidity, air pollution is more serious, more ozone can show the special role.
Fifth, ozone is the most suitable way to dissolve ozone in water, the formation of the so-called "ozone water". Some developed countries in Europe and the United States will be "ozone water" called "universal water". Its sterilization rate is more than a thousand times higher than chlorine.
Sixth, ozone water can be used for women, children's underwear, underwear, diapers, bags and other disinfection, sterilization treatment.
Seven, ozonated water can be used to sterilize fruits and vegetables, meat, antiseptic, preservation of freshness, removal of odors. At the same time, it has the function of degrading the residual phosphorus-containing pesticides on the surface of fruits and vegetables, and it can prolong the freshness period of food.
Eight, ozone water can clean the skin, skin care, reduce cosmetic stimulation of the skin. The use of ozone water cold compresses, soaking burns, cuts, bruises, can accelerate wound healing, to prevent infection.
Nine, ozone products can be widely used in: family, hospitals, hotels, restaurants, beauty salons, hairdressing, public **** bathroom, food processing industry, schools, kindergartens, homes for the elderly, finance, securities, offices, entertainment venues, the army, industry, agriculture, fisheries, aquaculture and other areas of environmental protection.
Ten, the role of ozone therapy in the human body
(1) so that bacteria, viruses, etc. inactive Ozone can destroy the integrity of the cell membrane, thus entering the cell, making it inactive, and will remove them from the body, with healthy cells to replace them.
(2) Promote Circulation For circulatory disorders, ozone can reduce or remove the clumping of red blood cells in the blood, restoring their elasticity so that they can pass through the capillaries and enhance the absorption of oxygen. It can also increase arterial pressure, reduce blood viscosity and promote blood circulation. The oxidation of platelets by ozone can also play a role in removing waste to unblock blood vessels.
(3) Promote the metabolism of oxygen Ozone can promote the rate of glycolysis in blood red blood cells, promote the release of oxygen in human tissue. It can also stimulate free radical clearing agents, enzymes are produced by some protective enzymes. Accelerates the Kreb's cycle and increases ATP production. Also NaOH increases the production of a vasodilator.
(4) Peroxidase formation Ozone reacts with unsaturated fatty acids to produce hydrogen peroxide, lipid peroxidation products include: alkoxyl, peroxyl, monomorphic itchy, ozonated oxides, carbons, alkanes and dilute hydrocarbons.
(5) decomposition of malignant tumors Ozone can inhibit the growth of tumors. In addition, ozone can also oxidize the malignant cell lipid layer, phagocytosis to produce H2O2 and carboxyl groups to kill bacteria and viruses. The principle is that ozone converts L-arginine to ornithine. Nitrites and nitrates.
(6) Parallel treatment Ozone is not a medicine, nor is it any magic, it is just an effective treatment to make the human body restore health. And it is the body's immune system that really works.
Ozone (chemical molecular formula for O3), also known as live oxygen, triple oxygen, super-oxygen, oxygen-rich, widely present in the ozone layer 20 kilometers away from the earth's surface, because it can absorb the vast majority of ultraviolet radiation from solar radiation, to protect the earth's living creatures from harm, and is widely concerned about the world.
