[0021] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made, belong to the scope of protection of the present application.

[0022] Please refer to Figs. 1-3 The present application provides the following technical solutions:

[0024] Wastewater is introduced through the liquid inlet 2, and oil-containing wastewater passes through the drainage holes 10 on each baffle 7 and gradually fills the entire oil-water separation tank body 1. After the oil-containing wastewater fills the entire oil-water separation tank body 1, the operator opens the liquid outlet 3 and adjusts the liquid level of the oil-containing wastewater in the oil-water separation tank body 1, so that the oil pollutants in the upper layer of the liquid overflow from the overflow oil outlet 5 of the oil drain pipe or oil drain groove, thereby continuously completing the oil-water separation operation, ensuring the processing capacity of the oil-water separator and saving the floor area.

[0025] The oil-water separation tank body 1 is provided with N baffle plates 7 in the cavity along the axis thereof, the number of the baffle plates 7 is 4, the first baffle plate 7 and the third baffle plate 7 are provided with drainage holes 10 near the lower part of the inner wall of the cavity of the oil-water separation tank body 1, and the second baffle plate 7 and the fourth baffle plate 7 are provided with drainage holes 10 near the upper part of the inner wall of the cavity of the oil-water separation tank body 1. Adjacent cavities are connected through the drainage holes 10 provided on the baffle plates 7 between them; the drainage holes 10 on the adjacent two baffle plates 7 are located on the left and right sides of the vertical plane where the axis of the oil-water separation tank body 1 is located.

[0026] The flow path of the oil-containing wastewater in the cavity of the oil-water separation tank body 1 is S-shaped after multiple turns, and the cross arrangement of the drainage holes 10 on the multiple baffle plates 7 promotes the collision of the tiny oil particles in the oil-containing wastewater in the multiple-turn flow to aggregate into larger oil particles and form an oil layer; the baffle plates 7 and the drainage holes 10 lengthen the flow path of the oil-containing wastewater in the cavity of the oil-water separation tank body 1, avoiding the direct discharge of part of the oil-containing wastewater that has not been stratified, thereby improving the oil-water separation rate and the settling time of part of the oil-containing wastewater.

[0027] The liquid inlet 2 and the liquid outlet 3 are respectively arranged on two non-adjacent cavities.
