In sewage treatment practice, air flotation separation and purification is one of the effective process methods for oil pollution, suspended solids, algae, etc. with a density close to water. Multiphase mixed air flotation, as a new type of air flotation equipment, can more conveniently and effectively remove oils, gel like substances, and suspended solids from industrial and urban wastewater. It is a mature and excellent sewage treatment technology. Due to the unique performance of multiphase mixed air flotation, it can be applied in many different fields and has advantages such as simple design, convenient operation, and stable and reliable operation.
No need for air compressor and pressure vessel;
Save operating costs and land area, and save investment;
Simple, compact, and maintenance free;
The performance of multiphase mixed air flotation mainly depends on the gas content in the multiphase mixed liquid. When the pump sucks in liquid, a certain negative pressure is formed at the pump inlet, and air is sucked in together with the liquid through the suction hole. After being sheared by the high-speed rotary cutting pump impeller, the gas dissolves in the liquid. By adjusting the operating conditions and the mixing ratio of gas and liquid, highly dispersed microbubbles can be obtained or the requirements for larger gas carrying capacity can be met. According to the different specifications and models of the pump, the gas content in the liquid can reach 30%. When these saturated (or even supersaturated) dissolved gases enter the dissolved gas tank, after a certain period of stability, they are instantly depressurized by the release device to release highly dense water with an average diameter of less than 30 μ The tiny bubbles of m. Finally, the coagulated wastewater enters the air flotation tank and mixes with these microbubbles. The microbubbles attach to the suspended solids and bring them to the water surface. After reaching the water surface, the solid suspended solids rely on these bubbles to support and maintain them on the water surface. The floating slag formed on the surface is scraped into the floating slag tank by a scraper.
