The invention provides an oil-water separation device for a transformer accident pool, comprising an oil-water aeration tank and an oil-water separation pipe, wherein an aeration pipe and a water supply pipe are arranged at the bottom of the oil-water aeration tank, and an oil-water overflow pipe is arranged at the top, and an oil-water feed port is opened on the oil-water separation pipe, and the oil-water feed port is connected to the oil-water overflow pipe. When the sewage of the transformer accident pool is subjected to the oil-water separation operation, the sewage first enters the oil-water aeration tank, and the liquid level is controlled to the entrance of the oil-water overflow pipe. Aeration, on the one hand, separates the oil and water, and reduces the oil content in the water phase.

After a period of time, the oil-water separation pipe is allowed to stand, so that the oil and water in the oil-water separation pipe are separated into layers. After the standing and separation, the water phase at the bottom can be returned to the oil-water aeration tank for secondary aeration to increase the treatment depth. The oil phase is discharged, which greatly reduces the amount of water in the oil phase, and realizes true oil-water separation.
