Description

technical field

[0001] The invention relates to a water treatment device, more specifically to an impeller-induced air flotation device for removing oil and suspended matter in water. Background technique

[0002] The working principle of the air flotation device is to use micro-bubbles to absorb pollutants such as oil and suspended solids in the water, and carry the pollutants to the water surface to form scum, so as to achieve the purpose of purifying water quality. According to the generation method of microbubbles in water, air flotation can be divided into pressurized dissolved air flotation, electrolytic air flotation, jet air flotation, impeller air flotation, vacuum air flotation and other technologies. Dissolved air flotation and impeller air flotation are widely used at present, while other technologies are relatively less used. Dissolved air flotation is based on the difference in the solubility of air in water under different pressures. Microbubbles are generate...
