[0020] Example 1:
[0021] As shown in Figure 1, the present invention includes a tank body, water inlet section A, coalescing air flotation section B, dosing mixing reaction section C and air flotation sedimentation and slag removal section D, sewage through the water inlet pipe 1, inlet The water valve 2, the water inlet pump 3, the electronic flow meter 4 are pumped into the conical buffer hopper 5 through the water inlet pump. The sewage flows into the egg tray type coalescing packing layer 7 of the coalescing air flotation section B evenly from the liquid distribution wall 6, and the sewage Crude oil is coalesced by the filler to form oil droplets that float up. After passing through the filler layer, the crude oil is combined with the air bubbles released by the perforated cloth air pipe 8 and quickly rises to the water surface under the action of the air bubbles. In the other slop tank, the degreasing sewage flows from another liquid distribution wall through the overflow plat
