Abstract
Provided are a method of treating spent caustic occurring in a refinery process, a petrochemical process, and an environmental facility, and an apparatus thereof, wherein the spent caustic may be economically treated by a Fenton-like oxidation reaction at room temperature and atmospheric pressure in a reactor in which catalyst structures are stacked as compared to conventional methods of treating spent caustic.
