The shallow air flotation device is a set of air flotation devices, which can effectively change the static inflow of the traditional air flotation to a certain extent, and the dynamic water discharge is dynamic water inflow and static water discharge, that is, the mixed sewage containing suspended particles with microbubbles is entered. When the air floatation tank is inside, the outflow device is moved, and the horizontal flow velocity of the mixed waste water is lower than that of the outflow device, thereby suppressing the turbulent flow in the tank, thereby enabling smooth air flotation separation (so-called "zero speed principle") ), the rising speed of the flotation body reaches or approaches the theoretical rising speed, which improves the treatment efficiency, and reduces the residence time of the wastewater in the shallow air flotation tank from the traditional 30-60 min to 3 min, and collects coagulation, slag, Drainage and mud discharge are integrated and it is an efficient wastewater treatment device. The overall shape is cylindrical, compact and the pool is shallow.

The shallow air-floating body consists of five parts: the pool body, the rotating water distribution mechanism, the melt release mechanism, the frame mechanism, and the water collecting mechanism. The water inlet, the water outlet and the scum discharge port are all concentrated in the central area of the pool body, and the water distribution mechanism, the water collecting mechanism and the dissolved gas release mechanism are closely connected with the frame and rotate around the center of the pool body. The device provides a complete set of equipment assembly and control system, which is combined with centralized control and distributed control to achieve a good operating condition of the device.

The separation technology of shallow air flotation means that the air and water are dissolved in the water under a certain pressure condition, and the gas is desirably dissolved in the water, and then the formed pressure dissolved water is released by decompression. A large amount of fine bubbles are generated, which are in full contact with the suspended flocs in the water, so that the suspended flocs in the water adhere to the microbubbles, float to the surface with the bubbles, form dross and scrape off the dross, thereby purifying the water.www.khnwatertreatment.com
