The invention discloses an oil-containing sludge and high-iron red mud synergistic resourceful treatment method which comprises the following steps: mixing high-iron red mud and oil-containing sludge according to a preset mass ratio to obtain a mixed material; the mixed material is subjected to pyrolysis, and pyrolysis oil, pyrolysis gas and pyrolysis residues are obtained. According to the method, secondary pollution can be reduced, resources in the oily sludge can be recycled, the cost of the catalyst is reduced, and the oily sludge is cooperatively treated by solid waste; meanwhile, the recycled pyrolytic oil is low-carbon-number pyrolytic oil. 本发明公开了一种含油污泥和高铁赤泥协同资源化处理方法，所述方法包括，将高铁赤泥与含油污泥按照预定的质量比进行混合，得到混合物料；将所述混合物料进行热解，得到热解油、热解气和热解残渣。通过该方法可减少二次污染、含油污泥中资源的再利用、降低催化剂成本的固废协同处理含油污泥，同时本申请所回收的热解油为低碳数热解油。
