1. The mixed liquid flowing into the air flotation equipment enters the coagulation tank, and after fully reacting with the coagulant in the coagulation tank to form flocs, it is mixed with the tiny bubbles contained in the dissolved air water formed by the dissolved air pump in the central water inlet pipe. Contact, and then enter the contact area of the device by rotating the water distribution pipe.
2. Under the condition of relatively stable water body, these micro-bubbles mix and contact with the mixed liquid, and absorb the biological flocs in the mixed liquid to float up. After 15-25s residence time, they quickly overflow to the separation area along the direction of the deflector. In the separation zone of the floating equipment, these tiny bubbles with a certain buoyancy continue to float up. After 2~3 minutes, the biological flocs float up to the surface of the separation zone to achieve efficient separation.
3. The separated effluent is collected by the water collection pipe at the bottom of the pool and returned to the closed landscape pool of reclaimed water.
