What are the uses and hazards of ozone? What does ozone do?

Ozone is also active against yeast and parasites, for example, it can be used to remove the following types of microorganisms and viruses.

Viruses ozone has been shown to be very virulent against viruses, e.g. Poloi virus loses its activity in 2 minutes at an ozone concentration of - mg L.

The sporangia are completely removed in minutes at an ozone concentration of mg l.

Spores are 10 - 15 times more resistant to ozone than growing bacteria due to the protection of the spore coating.

Fungi Candida albicans and Penicillium can be killed.

Parasites (e.g., mites) are killed after 3 minutes.

It can quickly kill E. coli, Staphylococcus aureus, Candida albicans and other germs in the air.

It can decompose the smell of odor, smoke, and strong perfume in the air.

In addition, ozone can also oxidize and decompose pollutants in water, and has significant effects on odor, decolorization, sterilization, removal of phenols, cyanide, iron, manganese and reduction of COD and BOD in water treatment.

1. Protective.

The ozone layer absorbs ultraviolet rays below the wavelength of sunlight, protecting people, animals and plants on Earth from short-wave ultraviolet light. Only UVA and a small amount of UVB can radiate to the ground, and UVA is much less harmful to biological cells than UVA.

2. Heating effect.

Ozone absorbs ultraviolet rays from sunlight and converts them into heat energy to heat the atmosphere, and since the atmospheric temperature structure has a peak at an altitude of about 50 km, there is a warming layer 15 50 km above the Earth. The temperature structure of the atmosphere has an important influence on the circulation of the atmosphere, and the cause of this phenomenon is also due to the high distribution of ozone.

3. The role of greenhouse gases.

In the upper troposphere and at the bottom of the stratosphere, the role of ozone is equally important. If ozone decreases at this height, there will be a drive to lower the surface air temperature. Therefore, the high distribution and variation of ozone is extremely important.

In 1840, when Schebyne in Germany electrolyzed dilute sulfuric acid, it was found that there was a special odor gas released, so it was named ozone. At room temperature and pressure, the stability is poor, and it can decompose into oxygen by itself. Ozone has the smell of grass, inhaling a small amount is beneficial to the human body, and inhaling too much is harmful to human health.

Non-flammable, pure. Oxygen can be turned into ozone by electric shock.

Ozone can be used to purify the air, bleaching drinking water, sterilization, treating industrial waste and as a bleaching agent. In summer, due to the influence of industrial and automobile exhaust fumes, ozone is formed and accumulated on the surface, especially in agricultural and forestry areas around large cities. Surface ozone has an erosive and damaging effect on the human body, especially on the eyes, respiratory tract, etc.

Surface ozone is also harmful to crops or forests.

It is used as a strong oxidizing agent, bleaching agent, fur deodorant, air purifier, disinfectant and disinfectant, and disinfection and deodorization of drinking water. Ozone can be used to replace many catalytic oxidations or high-temperature oxidations in chemical production, simplifying production processes and increasing productivity.

Ozone can also be a powerful bleaching agent, so it is often used as a bleaching agent, purifying agent, and disinfectant in daily life. In chemical production, ozone can also be used to replace many oxidation, catalysis or high-temperature oxidation to improve productivity.

The role of ozone is still very large, it can play the role of sterilization and sterilization, and its sterilization space is large, the effect is good, so most of them will use ozone.

Compared with oxygen, ozone has a large proportion, has a fishy odor, is easily soluble in water, and is easy to decompose. Ozone is composed of three oxygen atoms, that is, an oxygen molecule carries an oxygen atom, this oxygen atom is extremely active, which determines that ozone is only a temporary state, and the oxygen atoms carried by it are used up due to oxidation, and the remaining ones are combined into oxygen and enter a stable state. Therefore, there is no secondary pollutant produced in the conversion process of ozone with oxygen, which is the biggest advantage of ozone in environmental protection, food processing, medical treatment and other fields.

Ozone is a strong oxidizing agent that can take an oxygen ion in the air so that it can clean something around us. But its strong oxidizing properties can also cause damage to our bodies.

Sterilization, forming an ozone layer to block ultraviolet rays, and the destruction of the ozone layer will lead to global warming. Ozone is a gas that smells of rotten eggs.

Ozone is an allotropic form of oxygen, a pale blue gas with a fishy odor. Ozone can purify drinking water, purify the air, remove bacterial residues on tableware, and achieve the effect of disinfection and sterilization. When washing clothes, the use of ozone for water medium disinfection can well remove the odor on the clothes.

Ozone can absorb harmful radiation from sunlight, allowing humans to avoid the damage caused by ultraviolet rays. Ozone is used in wastewater treatment to decolorize and oxidize cyanide in electroplating wastewater. In addition, ozone can also control all airborne diseases and most soil-borne diseases of fruit and vegetable crops such as cucumbers, green peppers, and eggplants in greenhouses.

1. Ozone is an allotrope of oxygen, ozone is an unstable gas with a special odor, in the room temperature environment, ozone is light blue, and the ozone has a very strong oxidizing ability, ozone is a good oxidant.

2. Ozone can be used to disinfect drinking water, ozone has a fast killing effect and good effect, and ozone also has the advantages of color removal and odor, ozone can be used to treat industrial wastewater, ozone can reduce the biochemical oxygen demand and oxygen consumption of water, and destroy toxic compounds.

3. Liquid ozone can also be used as an oxidizer for medium fuel.

1. Harm to the human body.

The National Ambient Air Quality Standards (NAAQS) set the limit of 260 g m3 of ozone that a person can accept in an hour. Exposure to 320 g m3 ozone for 1 hour can cause coughing, dyspnea, and decreased lung function. Ozone can also participate in the reaction of unsaturated fatty acids, amino groups and other proteins in living organisms, so that people who are directly exposed to high concentrations of ozone for a long time have symptoms such as fatigue, cough, chest tightness and chest pain, wrinkles, nausea and headache, rapid pulse, memory loss, and vision loss.

2. Other hazards.

Ozone can also make plant leaves yellow or even wilt, causing damage to plants, and even causing a reduction in the yield of agricultural and forestry plants, and a decline in economic benefits. Ozone can react quickly with organic compounds containing unsaturated carbon-carbon bonds in indoor building materials (such as surface coatings such as latex coatings), household products (such as cork appliances, carpets, etc.), silk, cotton, cellulose acetate, nylon and polyester products, resulting in dye fading, image layer decolorization, tire aging, etc.
