Description

[0002] With the rapid development of industrialization and urbanization, the problem of water pollution has become increasingly serious. Traditional water treatment methods, such as sedimentation, filtration, and chemical treatment, can remove suspended solids and some dissolved pollutants in water to a certain extent, but their treatment effects on fine suspended solids and refractory organic matters are limited. Due to their small size, micro-nano bubbles have unique physical properties such as long residence time, large specific surface area, high surface negative charge, and high mass transfer efficiency, and have been increasingly widely used in the field of water treatment. The dissolved air release method is a commonly used micro-nano bubble generation mechanism.
