The invention relates to treatment equipment and a process of oily sludge and sand. The equipment is characterized in that one side of a rotary kiln is provided with a crude oily sludge and sand inlet, a thermosetting carrier reflux port, a rotary kiln driving motor and a slag discharging port, and the other side of the rotary kiln is provided with an oil gas outlet and a thermosetting carrier discharging port; the oil gas outlet is connected with a condenser; the thermosetting carrier discharging port is communicated with a fluidized bed through a chain bucket; a cyclone separator is arranged in the fluidized bed; solid separation and regeneration of a thermosetting carrier are carried out through the cyclone separator; the cyclone separator is communicated with the rotary kiln through the thermosetting carrier reflux port; and the bottom of the fluidized bed is connected with an air blower through a pipeline. The process has the beneficial effects that in production operation, oil and sludge separation is c
