The invention relates to the technical field of water treatment, in particular to an oil sludge separation treatment method and system applied to a sewage sedimentation tank. When the device is applied, efficient separation treatment of oil films and sludge in sewage can be achieved. By adjusting the power and the direction of the wave maker, the water flow can be dynamically adjusted according to the actual thickness of the oil film and the sludge, so that the removal efficiency is improved. When the oil film is thick, the water surface flow velocity is increased to improve the oil film removal efficiency, and when the silt is much, the bottom flow velocity is increased to improve the silt treatment efficiency. And when the oil film and the sludge are both thick, the direction of the second side wave maker is adjusted to form a flowing fault in the middle of the water body, the migration of the oil film to the water bottom and the suspension of the silt to the water surface are reduced, and thus the oil film and the sludge are independently treated. Under the condition that the oil film and the sludge are both thin, large circulation is formed by increasing the power of all the wave generators, the accumulation speed of the oil film and the sludge is increased, and therefore the overall treatment efficiency is improved.
