Thus, the primary separation tank 1 and the secondary separation tank 2 play the role of separating oil and dirt water respectively, the pipeline 3 plays the role of connecting the primary separation tank 1 and the secondary separation tank 2, so that the oil and dirt water flows through the primary separation tank 1 and the secondary separation tank 2 in turn, the primary separation tank 1 plays the role of supporting and fixing primary coalescing core assembly 10, first oil separation cover 11 and dirty water inlet 12, primary coalescing core assembly 10 plays the role of separating and filtering the oil and dirt water for the first time, first oil separation cover 11 plays the role of isolating oil and dirt water, dirty water inlet 12 plays the role of introducing the oil and dirt water, the secondary separation tank 2 plays the role of supporting and fixing second oil separation cover 20, subdivision coalescing core assembly 21 and clean water outlet 22, subdivision coalescing core assembly 21 plays the role of separating and filtering the oil and dirt water for the second time, second oil separation cover 20 plays the role of isolating oil and dirt water, and clean water outlet 22 plays the role of discharging the separated and filtered clean water.

[0015] As Figure 1 As shown in the embodiment, the top and bottom of the primary separation tank 1 are respectively provided with first oil outlet 13 and first pollution outlet 14, and the top and bottom of the secondary separation tank 2 are respectively provided with second oil outlet 23 and second pollution outlet 24. Thus, the primary separation tank 1 plays the role of supporting and fixing first oil outlet 13 and first pollution outlet 14, and first oil outlet 13 plays the role of separating and discharging the oil and dirt water flowing through the primary separation tank 1.

[0016] As Figure 1As shown in the figure, in this embodiment, both the primary separator 1 and the secondary separator 2 are provided with transparent oil windows 4 on their side walls. Therefore, the primary separator 1 and the secondary separator 2 respectively support and fix the transparent oil windows 4, which allow observation of the oil-water separation process in the primary separator 1 and the secondary separator 2.

Therefore, the first oil separator 11 and the second oil separator 20 serve to separate and isolate oil and water. The oily wastewater in the primary separation tank 1 flows from bottom to top, so the opening of the first oil separator 11 faces downwards. The oily wastewater in the secondary separation tank 2 flows from top to bottom, so the opening of the second oil separator 20 faces upwards.
