A two-step method resource treatment process for sludge containing oil is composed of two steps of hot emulsion breaking phase separation and normal temperature air float separation. Sludge containing oil is melted with hot water with the volume of 2-5 times of the volume of the sludge, mixed liquid is in a fluidized state, the mixed liquid of the sludge containing oil is mixed with a compound emulsion breaking agent through a mixer to enter a three-phase separator, and three-phase separation of oil, sludge and water is achieved by slowly stirring the mixed liquid. Oil in a fluidized state atthe upper layer overflows out of the separator to enter an oil recycling tank, and sludge-water mixed water at the lower layer is cooled by a heat exchanger A to enter the air float separator to be separated at the normal temperature. Oil at the upper layer of the air float separator enters the oil recycling tank, and sludge-water mixed liquid at the lower layer is sent into a centrifugal machineto perform sludge-water separation.
