A mixture of an oil sludge and an oil-contained waste water is first separated into a first oil-contained water and an oily dust containing metal-contained dust, fine metal powder and small fragments. Secondly, the oily dust is washed and separated into a harmless oil-free dust and a second oil-contained water containing the metal. Finally, both the first and second oil-contained water are separated into oil, harmless water and metal hydroxide by electrolysis. Thus, the mixture of the oil sludge and the oil-contained waste water is separated into components, which are in turn recovered, recycled, or converted into new materials, and the purification of the waste water can be realized.
