Method for rapidly treating oily sewage in port

The invention discloses a method for rapidly treating oily sewage in a port. Oily sewage in the port is sequentially subjected to nine procedures including sewage collection, adsorption by an oil absorbent felt, oil-water separation, air-floating oil removal, ultrasonic oxidation, flocculation reaction, adsorption reaction, filtering for impurity removal and sterilization treatment, so that the oily sewage in the port can be rapidly treated, the removal efficiency is high, the effluent quality is stable, pollutants are basically removed, and the requirements for recycled water can be met. The method has remarkable time efficiency, can rapidly treat polluted water, and avoids the expansion of pollution range of oil.
