Ozone, also known as oxygen-enriched, trivalent oxygen and superoxide, is one of the strongest oxidants known to be available. It can oxidize and denature the protein shell of bacteria and fungi, thus killing bacterial propagules and spores, viruses and fungi. Ozone can kill more than 99% of Escherichia coli, Streptococcus and Staphylococcus aureus, and can kill hepatitis virus and cold virus. Ozone has outstanding sterilization, disinfection and degradation of pesticides, and is considered as an efficient broad-spectrum fungicide.
Ozone can sterilize and purify the air, prevent cross-infection of diseases, and remove the peculiar smell in bedrooms, living rooms, kitchens and bathrooms. Ozone gas has the functions of sterilization, disinfection, mildew prevention and dust mites removal for indoor bedding, clothes, carpets, wardrobes, shoe cabinets and coins.
The most suitable method for disinfection and sterilization by ozone is to dissolve ozone in water to form so-called "ozone water". Some developed countries in Europe and America call "ozone water" universal water. The sterilization speed of "ozone water" is many times faster than chlorine. In daily life, using "ozone water" to disinfect underwear, underpants, diapers and bags used by women and children can have a particularly obvious effect. "Ozone water" has the functions of sterilization, preservation and odor removal for fruits, vegetables and meat, and also has the function of degrading phosphorus-containing pesticides on the surfaces of fruits and vegetables. We can also use "ozone water" to clean and maintain the skin and reduce the irritation of cosmetics to the skin. Cold compress and soaking burns, cuts and lumps with "ozone water" can accelerate wound healing and prevent infection; Washing bubbles with "ozone water" can prevent dermatosis and beriberi caused by fungi; Washing your hair with "ozone water" can remove dirt from the capillaries of your hair and reduce hair loss.
Scientific use is harmless.
According to experts, the safety and environmental protection of ozone have been recognized, and its application technology is quite mature. Br> If used scientifically, ozone will not do harm to human health.
In many countries, ozone is widely used in drinking water disinfection, air purification, food processing, medical care, aquaculture and other fields.
1902, the first large-scale water plant using ozone to treat water quality was established in paderborn, Germany, which pioneered the ozone water treatment. Now, there are thousands of ozone water plants in the world. The application of ozone in European and American waterworks has reached a universal level, and almost all mineral water and purified water manufacturers are equipped with ozone equipment. Since the early 1970s, the United States began to use ozone to treat domestic sewage, mainly for sterilization, decontamination, decoloration, etc. to meet the discharge standards. In Japan, sewage is treated by ozone and used as reclaimed water in water-deficient areas. The United States, Japan, Germany, France and other countries have established large-scale ozone sewage treatment plants in recent years.
Was ozone still the industry leader when writing frame 3? Psst? ぁ⑹? What's wrong with Ting? Ellipse? ⑾ 懔? In br> industry, the application of ozone in food industry is more popular. A Swedish beef company applied ozone to the storage and preservation of beef, starting from 1870. As early as 1904, Europe used ozone to preserve milk, meat products, cheese, protein and other foods. In the late 1930s, ozone generators were installed in 80% frozen egg banks in the United States. A few days ago, European and American countries used ozone in the storage, manufacture and transportation of fruits and vegetables.
In medical treatment, Japan used ozone for physical therapy as early as World War II. At present, ozone has many uses in medical care, such as air disinfection in wards and operating rooms, disinfection of medical instruments with ozone water, treatment of dental diseases with ozone, treatment of cancer with ozone combined with radiotherapy, treatment of gynecological diseases with ozone water, and injection of ozone gas to treat fistula, hemorrhoids and varicose veins. In terms of health care, it is popular in Japan to inhale "strong air" (air with low ozone concentration) to strengthen the body and spray the body with ozone water for sterilization and beauty.
Ozone can kill viruses and bacteria, but it does no harm to healthy cells, because the latter has a powerful balanced enzyme system. As long as ozone is used scientifically, there is no danger to human health. In fact, ozone has been used 100 years, so far there has not been an accident of death due to ozone poisoning in the world.
In addition, there is a saying that ozone can "kill" vitamins and other beneficial components in fruits and vegetables while disinfecting; However, it was confirmed by the Environmental Health Monitoring Institute of Chinese Academy of Preventive Medicine that soaking fruits and vegetables in qualified ozone equipment for 10 to 15 minutes had no obvious effect on vitamin C in fruits and vegetables.
Blind abuse can also damage life.
Scientific use of ozone will not cause harm to human health, but if ozone is abused blindly and "detoxified" without restraint, it will be impossible to sit back and relax.
Ozone itself is a non-toxic and safe gas, and its "poison" mainly refers to its strong oxidation ability. Experts believe that when the ozone concentration is higher than 1.5ppm, people must leave the scene, because ozone will stimulate people's respiratory system and cause harm in severe cases. At present, many countries and organizations have formulated human safety and health standards in ozone gas environment, and the product of its concentration and contact time can be regarded as a reference point: the standard of the International Ozone Association is: 0. 1ppm, and the contact time is 10 hour; American standard: 0. 1ppm, contact for 8 hours; German, French and Japanese standards: 0. 1ppm, contact 10 hour; China standard: 0. 15ppm, contact for 8 hours.
It has been reported that when the ozone concentration is 0.02ppm, people with a keen sense of smell can detect it. When the concentration is 0. 15ppm, it is the critical olfactory value, and most people can smell it. When the concentration reaches 1 ~ 10ppm, it is called the stimulation range, and when it is higher than 10ppm, it is the poisoning limit.
It is reported that when people are exposed to high concentrations of ozone, they may feel tingling in their skin and eyes, poor breathing, cough and headache. Long-term exposure can also lead to temporary abnormal lung function and cause lung tissue damage; People with allergies may also cause chronic lung diseases and even permanent injuries such as pulmonary fibrosis.
Therefore, experts remind consumers to check the safety inspection certificate and disinfection and sterilization report of the products when purchasing ozone generators. In addition, the more ozone produced, the better. It is more appropriate to generate 200 mg/m3 of ozone per hour, and the average household should not exceed 400 mg/m3. It takes about 60 minutes for ozone machine to make drinking water, and it will be reduced to 15 minutes before drinking. When used for air purification, people should be isolated from the room to be purified, and stop for a few minutes after ozone decomposition before opening the door. It is not suitable to use the ozone generator with high ozone concentration indoors for a long time. Excessive ozone concentration is harmful to human body, furniture and clothes.
