Answer:

Ozone and its role

This article is reprinted from Guanglei

Ozone (chemical molecular formula O3) is a kind of three oxygen atoms composed of grass fresh taste of light blue gas, the English translation of the "Fresh air", that is, "fresh air" meaning. Fresh air", that is, "fresh air" means.

Nature's ozone mainly exists in the Earth's surface 1.2-3.5 million meters in the air, in the role of the sun's ultraviolet light to form an ozone layer. It is a protective layer that shields organisms on the Earth's surface from ultraviolet rays. It can absorb 90% of the ultraviolet radiation, is the loyal "guardian" of mankind, to maintain the ecological environment of the Earth has an irreplaceable function.

There is a small amount of ozone produced in forests, by the sea, next to waterfalls, and after thunderstorms, with a concentration of 0.01-0.08ppm. Therefore, people in the above environment feel fresh air, fresh and refreshing, which is the reason for the existence of ozone.

In reality, the raw materials for ozone generation are water, air and electricity, which are inexpensive and not only free of secondary pollution, but also make the air fresher and the environment more pleasant.

The chemical nature of ozone is extremely active, it is in the free energy in the instantaneous generation of strong oxidation, sterilization, disinfection, detoxification work. Ozone is extremely easy to dissolve in water, dissolved in water with a stronger bactericidal ability, is 600-3000 times the chlorine, can quickly kill bacteria and viruses. Bacteria, viruses and ozone combined will change the molecular structure or energy transfer, resulting in the death of bacteria and viruses, no longer form new germs, can effectively remove a variety of bacteria, viruses, odors and new furniture and paint release of toxic gases (formaldehyde, benzene, etc.), the atmosphere in the right amount of ozone is very beneficial to human health.

By the same token, ozone can also decompose nicotine produced by smoking, preventing second-hand smoke from harming others, can decompose the toxicity of pesticides, and also eliminate the toxicity of sulfur dioxide produced by gas and coal burning, ozone can also eliminate some radiation damage to the human body.

Ozone is a highly effective disinfectant, bacteria, germs, fungi, mold germs, viruses and other microorganisms have a very strong killing power. Because ozone is diffuse gas, disinfection without dead angle, so disinfection and sterilization effect is good. At the same time, ozone can be rapidly decomposed at high temperatures to form oxygen, so there is no secondary pollution.

The content of ozone in the air within one millionth of the human body is very beneficial, because a small amount of ozone can *** central nervous system, accelerate blood circulation, increase the amount of oxygen in the blood, activate the cells, but a high concentration of ozone will make people feel uncomfortable, and even harm the human body, so it is necessary to control the amount of ozone generation.

First, the role of oxygen:

1, improve lung organ function. After inhaling negative ions for 30 minutes, the lungs can increase the absorption of oxygen by 20%, and discharge more carbon monoxide by 14.5%.

2, reduce blood pressure.

3. Enhance the function of heart muscle.

4, improve sleep.

5, make people refreshed.

6, improve work efficiency.

7, has obvious analgesic effect.

8, can activate a variety of enzymes in the muscle.

9, promote metabolism.

10, enhance the body's immunity to disease.

Second, the ozone sterilization, disinfection effect:

1, sterilization. Studies have shown that ozone is a broad-spectrum, highly efficient, rapid sterilization agent, it can quickly kill a variety of pathogens, viruses and microorganisms that cause disease in humans and animals. Ozone is a very strong oxidizing substance, the use of its oxidizing properties, can be destroyed in a relatively short period of time bacteria, viruses and other microorganisms of the biological structure, so that it loses the ability to survive. There are many other compounds that use oxidizing property to kill microorganisms to achieve sterilization effect, such as common chlorine, bleach, potassium permanganate, etc.. However, these biocides are not only slower than ozone sterilization, but also general biocides are harmful to the human body. Ozone is different from general sterilizers because excess ozone can be quickly decomposed into oxygen, which is beneficial and harmless to the human body. The sterilization effect of ozone is comparable to that of oxyacetic acid, stronger than formaldehyde, and twice as strong as chlorine. With the general bactericidal agent of progressive, cumulative sterilization disinfection function is different from the sterilization of ozone is rapid, when the concentration of which exceeds a certain value, disinfection sterilization can even be completed instantly. Humidity increases and temperature decreases can enhance the disinfection of ozone, when the ozone dissolved in water has a stronger, faster sterilization and disinfection. The use of ozone sterilization disinfection without secondary pollution, in the treated water, air, food, appliances, etc., no residual harmful substances, which is also other germicides can not be compared to the advantages of the spread.

2, detoxification. Ozone can effectively remove toxic gases such as C0, S02, mustard gas, etc. through oxidation.

Ozone dissolved in water can be oxidized, decomposition and thus effectively remove toxic substances in water such as heavy metal ions, organic poisons, cyanide, sulfide and dichlorvos, oxidized lethargy, malasulfuric acid and other pesticides.

3, protection and preservation. Due to the strong killing effect of ozone on bacteria and microorganisms, the use of ozone water treatment of meat and other foods can achieve preservation, elimination of odor, preservation of freshness. In the ozone produced at the same time can also produce a large number of negative ions, some negative ions in the air can effectively inhibit the respiration of fruits and vegetables, slowing down its metabolic process. At the same time, ozone can kill pathogenic bacteria that cause fruit and vegetable decay, decomposition of fruits and vegetables produced in the storage process with the role of ripening metabolic waste such as ethylene, alcohols, aldehydes, aromatics and other substances. In this way, under the action of ozone and negative ions inhibit the metabolism of fruits and vegetables and microbial pathogens breeding and spreading, thus delaying its aging, preventing its decay and deterioration, to achieve the effect of preservation. Studies have shown that the ozone can make food, beverages and fruits and vegetables to extend the storage period of 3-10 times.

4, deodorization, odor. The main components of nature that cause odor and corruption are ammonia, hydrogen sulfide, methyl mercaptan, dimethyl sulfide, dimethyl disulfide, etc. Ozone can be chemically reacted with them to oxidize and decompose them into non-toxic, non-smelly substances, thus achieving the effect of deodorization.
