The super-effective shallow air flotation device is an advanced air flotation system, successfully designed using the "shallow pool theory" and "zero speed" principles to integrate agglomeration, air flotation, skimming, sedimentation, It is an efficient and energy-saving water purification equipment that integrates mud scraping. The CQJ super-effective shallow ion air flotation is an air flotation device that integrates flocculation, air flotation, skimming and mud scraping. It uses the "Shallow Pool Theory" Designed with the "zero-speed principle", the residence time is only 3-5 minutes, the water is forced to be distributed, and the inlet and outlet water are static. The adhesion of microbubbles and floc occurs in the entire air flotation separation process including the contact area. , the scum is discharged instantly, the water disturbance is small, the suspended solids in the effluent are low, the solid content of the slag is high, the suspended solids removal rate can reach more than 90-99.5, the COD removal rate can reach 65-90, and the chroma removal rate can reach 70 —95.
The CQJ super-effective shallow ion air flotation adopts a unique world-leading patented technology - the balanced energy dissipation device replaces the traditional releaser and greatly reduces the diameter of the microbubbles. The average diameter of microbubbles is only about 5 μm, which is at least 30 times smaller than the current domestic and international average of about 150 μm. Because when the amount of dissolved gas is constant, the total area of ??microbubbles is inversely proportional to the square of its diameter, so the total area of ??microbubbles increases by at least several hundred times, while the density of microbubbles increases by nearly several thousand times. Theoretical research and experiments have shown that the smaller the diameter of the microbubbles, the stronger the tendency of the bubbles to adsorb suspended solids and the greater the adsorption force. This can be explained by the interface energy theory. The total area of ??microbubbles increases geometrically, which is equivalent to the amount of solids in wastewater. The total surface area of ??the three phases, water and gas, increases geometrically, so their tendency to try to reduce surface energy through adsorption is greatly enhanced. In the theory of air flotation, in addition to the mechanisms of bubble adsorption, bubble support, and floc adsorption, there is also the so-called "bubble entrainment" effect in the separation of suspended matter from the water body. During the rising process of dense bubbles, no matter how small the fine suspended solids are, their particle size is still much larger than that of water molecules, and they may be entrained in the bubble gaps of the bubble group and carried to the water surface to be separated. Obviously, the denser the bubble group, the stronger this effect will be, and the smaller the suspended solids that can be carried.
Unique dissolved gas system design, small size, high dissolved gas efficiency and compact structure. The equipment occupies a small area and is highly efficient.
