[0021] It should be noted that in operation, this high-efficiency oil-water separator fills the wastewater tank 2 with water through the wastewater pipe 3. A centrifugal pump 4 then pumps the water from the wastewater tank 2 into the oil collection chamber 602. The centrifugal pump 4 provides power to pump the water into the impurity removal chamber 601, the water outlet chamber 603, and the oil collection chamber 602. Due to the density difference between oil and water, under centrifugal force, the dispersed oil accumulates in the center of the slower-moving oil collection chamber 602. The heavier wastewater flows out from the water outlet 606. Through the cooperation of the water outlet 606 and the second conveying pipe 607, the wastewater is transported to the flotation tank 901. The accumulated waste oil is discharged through the oil outlet 608 and discharged through the overflow pipe for system collection and reuse. The top of the flotation tank 901 is open, through which chemicals are added to the flotation tank 901. Air from the air compressor 7 is delivered to the flotation tank 901 through the third delivery pipe 8. The air mixes the wastewater and chemicals inside the flotation tank 901. The servo motor 905 drives the threaded rod 903 to rotate. The rotation of the threaded rod 903 changes the position of the threaded block 904. The threaded block 904 drives one end of the scraper 906 to move. The slider 909 slides on the slide rod 908, driving the other end of the scraper 906 to move. The scraper 906 scrapes the oil in the flotation tank 901 and then discharges it through the waste discharge trough 907.

[0022] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
