The dissolved air flotation machine uses clean water or partially treated return water to absorb and mix the air through the microbubble generator to form dissolved air water, which is released by decompression in the air flotation tank, and the dissolved air in the water is reduced by 20-30% μ M bubbles form and precipitate, which has a high surface area and adsorption capacity, and can better remove the suspended solids of sewage with different concentrations. After treatment, part of the clean water (the design index is 20-40%, which can usually be used 30%) is mixed with air in the pressurized water dissolving tank through the air flotation circulating pump, and the air is dissolved in the water. At this time, the gas dissolving efficiency reaches more than 80%. The air dissolved in water is released from the water to form a particle size of 20-50 μ M, which combines with the suspended solids in the sewage to reduce the proportion of the suspended solids in the sewage until they float on the surface of the water body; A large amount of scum is formed, and then the scum is removed by the chain scraper installed on the air flotation tank to achieve the treatment effect.
