Abstract

The invention discloses an air-floatation oil removal tank for treating oil-containing waste water and an oil removal method. The air-floatation oil removal tank comprises a tank body, wherein the upper part of an inner cavity of the tank body is a separation area, the lower part of the inner cavity of the tank body is vertically provided with a separation plate, and the lower part of the inner cavity of the tank body is divided by the separation plate into an air floatation area and a water outlet area; the tops of the air floatation area and the water outlet area are respectively communicated with the separation area; the top of the tank body is provided with an air outlet; the top of the tank body is provided with an oil outlet; the bottom of the tank body is provided with a water outlet communicated with the water outlet area; the tank body is also provided with a water inlet for transporting waste water to be treated to the air floatation area; and the air-floatation oil removal tank comprises an air transport apparatus for transporting gas to the air floatation area. By adopting the air-floatation oil removal tank, the oil removal effect can be improved, and the oil in the oil-containing waste water can be sufficiently separated.

Description

technical field [0001] The invention relates to an air flotation degreasing tank for treating oily waste water, and also relates to an air flotation degreasing method, which belongs to the technical field of oily waste water treatment.
