Then, the filter material oil removing agent and the filter material are respectively added into the U-shaped groove, and under the heating condition of the steam boiler on the U-shaped groove, the filter material oil removing agent can enhance the activity of oil pollutants on the surface of the filter material, so that the oil pollutants on the surface of the filter material are separated from the filter material under the stirring action of the spiral stirring conveying paddle.
