The harm and prevention of ozone

Many people first learned about ozone from the news about the "hole in the ozone layer over Antarctica." Since then, in the eyes of many people, ozone is a layer of safety that protects us. This is not the case. Ozone can indeed absorb radiation and heat the atmosphere, but this is the role played by the ozone layer above the stratosphere. In the troposphere where we live, ozone is indeed harmful to humans. Ozone is a very strong oxidant, which is converted from oxygen in the air under conditions of electric discharge, ultraviolet light, electrolysis, etc. It has a wide range of applications in water treatment, medical disinfection, industrial oxidation and other fields. Ozone is nowhere around us. Not here. Ozone itself is quite unstable and will decompose into oxygen by itself under radiation or high temperature.

Excessive ozone in the air can damage the respiratory tract and mucous membranes, and prolonged exposure to high concentrations of ozone can also cause permanent heart disorders, and the usual protective measures such as masks have no effect on ozone. In summer when the sun is strong, ozone is more likely to be produced under the action of nitrogen oxides, so ozone pollution is more likely to occur in cities in summer, which is also a type of photochemical pollution.

To control ozone pollution, we need to start from the source in order to play a real role. There are two main reasons for the excessive ozone in the urban air. One is the generation of ozone under the action of nitrogen oxides, and the other is the failure of industrial oxidized ozone exhaust emissions. Treatment from these two root causes can effectively reduce most of the ozone pollution.

The nitrogen oxides in urban air mainly come from automobile exhaust emissions, and some of them come from factory exhaust emissions. Now that the National Sixth Standard is implemented, it will greatly reduce the emission of nitrogen oxides in automobile exhaust. At the same time, it is also necessary to do a good job in the inspection and management of excess vehicle emissions to prevent vehicles that do not meet the emissions standards from driving on the road. For industrial facilities with large-scale combustion equipment such as thermal power plants, a certain amount of nitrogen oxides will also be generated in the exhaust gas, and desulfurization and denitrification equipment are generally equipped. At present, the measures in this area are relatively good, mainly to do a good job in continuous management and Supervise and prevent the failure of desulfurization and denitrification equipment operation.

The non-compliance of industrial oxidized ozone exhaust emissions is also an important cause of ozone pollution. With the continuous and widespread promotion of water treatment and the vigorous development of medical disinfection, ozone disinfection and oxidation are currently relatively environmentally friendly methods. However, after many devices use high concentrations of ozone, there are still relatively high concentrations of ozone remaining in the tail gas. Because ozone will decompose by itself, the current domestic emissions in this area are not very strict, resulting in the direct emission of residual ozone from many equipment in the air. For the treatment of these ozone tail gas, the current better way is to pass the tail gas into the ozone decomposition catalyst to completely decompose the ozone before discharging. Currently, the price and quality of catalysts on the market are uneven, and there is no uniform standard. In many cases, due to economic reasons, catalysts with substandard effects are selected, but this often fails to achieve the goal of ozone exhaust gas treatment. When choosing an ozone decomposition catalyst, it is best to choose it through actual tests to ensure the treatment efficiency and service life, so as to economically and effectively prevent ozone tail gas pollution.

The harm of ozone to the environment and human health is visible. It is the responsibility of each of us to maintain a healthy and safe air environment. minstrong has been committed to the development and application of ozone decomposition catalysts for a long time, and has accumulated profound technology and experience in the field of ozone exhaust gas treatment. Minstrong Ozone Decomposition Catalyst can decompose ozone efficiently, and can help customers effectively control the occurrence of ozone tail gas pollution.
