The dissolved gas system can clean different degrees of wastewater during the operation, and to some extent, as its untreated sewage first enters the small aeration section of the air flotation machine, the air on the liquid surface will be When input into the water, the microbubbles are generated at any time, and the imbalance between the water mixture and the liquid produces a vertical upward buoyancy to bring the solid suspension to the surface.
After the suspended matter reaches the surface of the water, the suspended solids are supported and maintained on the water surface by the bubbles, and are effectively removed by the radial airflow thrust. The sewage purified by the air flotation machine is discharged before being discharged. First enter the overflow tank through the outlet below the metal plate and then discharge.
The air-floating sewage treatment machine of the dissolved gas system is a steel structure. During the working process, the air is effectively sent to the pressure-dissolving gas tank through its pump, and is forced to dissolve in the water under a certain pressure, and is suddenly released. In the case, the air dissolved in the water is precipitated, and a large number of dense microbubble groups are formed during the slow rise, and the density of the suspended matter is lowered and floated to achieve the purpose of removing SS and CODcr.
The round steel structure is the main body and core of the water treatment machine. There are releasers, homogenizers, sludge pipes, outlet pipes, sludge tanks, scrapers and transmission systems. The release device is placed in the central position of the air flotation machine and is a key component for generating microbubbles. The dissolved gas from the dissolved gas tank is mixed with the waste water here, and is suddenly released, causing severe agitation and eddy current to form a diameter of about 20-80 um. The microbubbles are attached to the flocs in the wastewater, thereby reducing the rising specific gravity of the flocs, separating the clean water, and the structure of the homogenizer is connected to the releaser, the main function is to separate the separated water and The sludge is evenly dispersed in the tank.http://www.shallowairfloatation.com/
