Ozone (chemical molecular formula O3) is a light blue gas with the smell of grass. The English translation is "Fresh air", which means "fresh air". Ozone in nature mainly exists at the altitude of 12-35 km on the earth's surface, and forms the ozone layer under the action of solar ultraviolet rays. It is a protective layer to protect life on the surface of the earth from ultraviolet rays. It can absorb 90% ultraviolet rays, is a loyal "guardian" of human beings, and plays an irreplaceable role in maintaining the ecological environment of the earth. After forest, seaside, waterfall and thunderstorm, a small amount of ozone is produced, with the concentration of 0.0 1-0.08 ppm. Therefore, people will feel fresh air and refreshed in the above environment, which is the reason for the existence of ozone. In real life, the raw materials of ozone are water, air and electricity, which is low in cost, not only has no secondary pollution, but also makes the air fresher and the environment more pleasant. The chemical properties of ozone are extremely active, and its free energy can produce strong oxidation in an instant, which can sterilize, disinfect and detoxify. Ozone is easily soluble in water, and has stronger sterilization ability, which is 600-3000 times that of chlorine, and can quickly kill bacteria and viruses. The combination of bacteria and viruses with ozone will change the molecular structure or energy transfer, leading to the death of bacteria and viruses and no longer forming new germs. Can effectively remove all kinds of bacteria, viruses, odors and toxic gases (formaldehyde, benzene, etc.). ) released by new furniture paint. Proper ozone in the atmosphere is very beneficial to human health. Similarly, ozone can decompose nicotine produced by smoking, prevent the harm of second-hand smoke to others, decompose the toxicity of pesticides, eliminate the toxicity of sulfur dioxide produced by gas and coal, and eliminate the harm of some radiation to human body. Ozone is an efficient disinfectant, which has a strong killing effect on bacteria, germs, fungi, mold spores, viruses and other microorganisms. Because ozone is a diffusion gas, there is no dead angle in disinfection, so the disinfection and sterilization effect is good. At the same time, ozone can be rapidly decomposed to form oxygen at high temperature, so there is no secondary pollution problem. When the content of ozone in the air is less than one millionth, it is very beneficial to human body, because a small amount of ozone can stimulate the central nervous system, accelerate blood circulation, increase active oxygen in blood and activate cells, but high concentration of ozone will make people feel uncomfortable and even hurt human body, so the amount of ozone must be controlled. First, the role of oxygen: 1, improve the function of lung organs. After inhaling negative ions for 30 minutes, the oxygen uptake in the lungs can be increased by 20%, and more carbon monoxide 14.5% can be discharged. 2. Lower blood pressure. 3. Enhance myocardial function. 4. Improve sleep. 5. It's refreshing. 6. Improve work efficiency. 7. It has obvious analgesic effect. 8, can activate a variety of enzymes in the body. 9. Promote metabolism. 10, enhancing immunity and disease resistance. Second, the disinfection effect of ozone: 1, disinfection. Studies have shown that ozone is a broad-spectrum, efficient and fast bactericide, which can quickly kill all kinds of germs, viruses and microorganisms that make people and animals sick. Ozone is a very oxidizing substance. With its oxidation, it can destroy the biological structure of bacteria, viruses and other microorganisms in a short time, making them lose their viability. There are many compounds that kill microorganisms by oxidation to achieve sterilization effect, such as common chlorine, bleaching powder, potassium permanganate and so on. But these fungicides are not only slower than ozone, but also harmful to human body. Ozone is different from ordinary bactericides, because excess ozone can be quickly decomposed into oxygen, which is beneficial and harmless to human body. The bactericidal effect of ozone is equivalent to that of oxyacetic acid, stronger than that of formaldehyde, and its bactericidal power is twice that of chlorine. Different from the progressive and cumulative sterilization of general fungicides, the sterilization of ozone is rapid, and even can be completed instantly when the concentration exceeds a certain value. The increase of humidity and the decrease of temperature can enhance the disinfection effect of ozone When ozone is dissolved in water, it has a stronger and faster disinfection effect. Ozone sterilization has no secondary pollution, and there is no harmful substance residue in treated water, air, food and utensils. This is also an incomparable advantage of other fungicides. 2, detoxification. Ozone can effectively remove toxic gases, such as C0, SO2 and mustard gas. Through the oxidation reaction. Ozone dissolved in water can be oxidized and decomposed, effectively removing toxic substances such as heavy metal ions, organic poisons, cyanide and sulfide, and pesticides such as dichlorvos, omethoate and malathion. 3. Protection and preservation. Because ozone has a strong killing effect on bacteria and microorganisms, treating meat and other foods with ozone water can achieve the effects of antisepsis, deodorization and preservation. At the same time, ozone can also produce a large number of negative ions. Some negative ions in the air can effectively inhibit the respiration of fruits and vegetables and delay their metabolic process. At the same time, ozone can kill pathogenic bacteria causing fruit and vegetable rot, and decompose metabolic wastes such as ethylene, alcohols, aldehydes, aromatics and other substances with ripening effect during fruit and vegetable storage. In this way, under the action of ozone and negative ions, the metabolism of fruits and vegetables and the propagation and spread of microbial pathogens are inhibited, thus delaying the maturity and aging of fruits and vegetables, preventing them from rotting and deteriorating, and achieving the effect of preservation. Studies have shown that ozone can prolong the shelf life of food, beverage, fruit and vegetables by 3- 10 times. 4. Deodorize and deodorize. The main components that cause odor and corruption in nature are ammonia, hydrogen sulfide, methyl mercaptan, dimethyl sulfide and dimethyl disulfide. Ozone can react with them and decompose them into non-toxic and odorless substances, thus achieving the effect of deodorization.
