The invention provides a treating method for oily sludge and relates to the technical field of oily sludge treatment. The treating method provided by the invention comprises the following steps: heating and stirring oily sludge, standing and then performing solid-liquid separation, thereby acquiring oily mud and oily liquid; introducing the oily liquid into a sewage treatment system for performing oil-water separation, and extracting and purifying the separated oil; adding a reagent into the oily mud for tempering; after tempering, deeply dewatering, thereby acquiring dewatered oily mud and filtrate; performing oil-water separation on the filtrate; performing drying treatment and pyrolysis carbonizing treatment on the dewatered oily mud. The treatment method provided by the invention is simple, convenient and efficient and can realize the reduction, harmless and recycling treatment of the oily sludge, the whole treating process flow operation occupies less area and the investment cost is low.
