Of course, the heating element 4 may also be other conventional heating elements. The waste water is heated to 35-40 ℃ by the heating element 4, so that oil, slag and water are physically layered.

As shown in fig. 1, the left side of the heating zone 1 is an air flotation zone 2, and the bottom of the air flotation zone 2 is communicated with the heating zone 1 so as to receive inflow of wastewater. The top of the air floating zone 2 is provided with an overflow port. The air flotation zone 2 is internally provided with a bubble blowing-in part 5, and the bubble blowing-in part 5 in the example is a cavitation air flotation system. The heated wastewater is physically layered through a cavitation air flotation system, and oil, slag and water are separated.
