PROBLEM TO BE SOLVED: To provide a processing method of a crude oil-containing waste liquid capable of effectively and surely separating and recovering crude oil and water of the crude oil-containing waste liquid in short time, and a processing facility thereof.;SOLUTION: There is provided a processing method of a crude oil-containing waste liquid having an addition process for adding a coagulant to the crude oil-containing waste liquid, a heating process for heating the waste liquid during or after addition either, and a centrifugation process for centrifuging the waste liquid to which the coagulant is added to separate three components of an oil component, water and a solid. For reducing moisture content of recovered oil, an emulsion breaker is added before conducting the centrifugation process. A polyamine-based coagulant is included as the coagulant.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
