Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a multifunctional oil-water separator. Background Art

[0002] When treating sewage, if there is a lot of grease on the surface of the sewage, an oil-water separator is needed to separate the sewage from the oil before the sewage begins to be discharged, so as to facilitate subsequent sewage treatment operations.

[0003] There are various types of oil-water separators currently, among which the simplest and most economical method is the gravity type, that is, after the oil-water mixture is stored in a separation tank, the oil and water are statically separated by gravity, and the light oil phase floats on the top of the water phase, and then the bottom water phase is discharged, and then the oil tank is discharged, that is, the purpose of oil-water separation is achieved. However, when the oil and water are discharged in layers, since the boundary between the two is difficult to control, a small amount of sewage often remains in the oil phase when the sewage is discharged. For this part of the water phase, it is difficult to separate it by gravity alone, and it has the defect of incomplete separation. For this reason, the utility model proposes a multifunctional oil-water separator to solve this problem. Utility Model Content
