After a period of standing, the oil will gradually float up to the floating oil reservoir 13 to form an oil layer due to the difference in specific gravity between the oil and the water.

In addition, the flotation transition zone 12 is arranged, so that the oil in the floating oil storage zone 13 can be prevented from being influenced by the circulating liquid flow when the device works. After the whole oil-water separation process is completed, the water replenishment electronic control valve 31, the water discharge electronic control valve 41, the oil discharge electronic control valve 71, and the electronic control valves 21 and 51 are closed, and the electronic control valve 61 is opened to discharge the liquid remaining in the tank 1, thereby cleaning the inside of the tank 1.
