The principle of treating heavy metals in water with ozone micro nano bubbles mainly utilizes the oxidizing properties of ozone bubbles and the special properties of micro nano bubbles.

Ozone micro nano bubbles have strong oxidation ability, which can oxidize heavy metal ions in water into smaller molecules, thereby reducing their toxicity and mobility. Ozone micro nano bubbles are a special type of bubble, with a diameter typically ranging from tens of nanometers to hundreds of nanometers, much smaller than ordinary bubbles. This type of bubble has a higher specific surface area and surface energy, and can better contact and react with heavy metal ions in water.

In the process of treating heavy metals with ozone micro nano bubbles, ozone molecules can undergo redox reactions with heavy metal ions in water, oxidizing them into smaller molecules, such as metal oxides or hydroxides. These small molecules can be removed from water through flocculation, precipitation, and other methods to achieve the goal of treating heavy metals.

In addition, ozone micro nano bubbles can also increase the dissolved oxygen in water, promote the self purification ability of water, and further improve the removal efficiency of heavy metals.

It should be noted that the effectiveness of ozone micro nano bubbles in treating heavy metals is influenced by various factors, such as ozone concentration, bubble size, reaction time, water quality, etc. Therefore, in practical applications, it is necessary to optimize and adjust according to specific situations.
