Characteristics of ozone micro and nano bubbles

Odorous micro nano bubbles have the advantages of large specific surface area, long residence time, self pressurization, dissolution and interface ζ With the characteristics of high potential, free radical generation and enhanced mass transfer efficiency, ozone micro nano bubbles are applied in the fields of environmental pollution control such as water oxygenation, air flotation process, enhanced ozonation, sterilization and odor removal, and enhanced biological activity.

Ozone micro and nano bubbles have strong oxidation and free radicals are produced by bubble rupture. When the micron bubble shrinks, due to the rapid increase of the charge density of the electric double layer, when the bubble breaks, the drastic change of the disappearance of the gas-liquid interface will release the energy accumulated by the high concentration of positive and negative ions on the interface, which can stimulate the generation of a large number of hydroxyl radicals. Hydroxyl radical has strong oxidation and can degrade pollutants in water that are difficult to degrade under normal conditions, such as phenol.

Ozone micro and nano bubbles eliminate odor in water

The substances that produce odor in the process of sewage treatment are mainly composed of carbon, nitrogen and sulfur. Only a few odor producing substances are inorganic compounds, such as ammonia, phosphorus and hydrogen sulfide; Most odor producing substances are organic compounds, such as low molecular fatty acids, amines, aldehydes, ketones, ethers, etc. According to the analysis of the water inflow of my sewage treatment plant, 80% of the water inflow is domestic sewage, that is, the content of organic matter is very high and the content of inorganic compounds is relatively small. Most of the substances that produce odor are organic compounds, such as low molecular fatty acids, amines, aldehydes, ketones, ethers, etc. these substances have active groups, which are prone to chemical reactions and are particularly easy to be oxidized. Ozone nano bubbles have the characteristics of strong oxidizability and generation of free radicals, oxidize active groups and eliminate peculiar smell, so as to achieve the principle of deodorization. In addition to removing odor, ozone can also prevent the re generation of odor. This is because the gas produced by ozone nano bubbles contains oxygen and air. Because substances containing odor are easy to cause odor in anoxic environment, ozone micro nano bubble treatment is adopted to form an oxygen enriched environment while deodorizing, which can prevent the recurrence of odor.
