| Abstract: | Oily cooling water from oil refinery was treated using combination of ozone oxidation and ion exchange. It is determined that the optimal pH is 10.5 in the process of ozone oxidation, and the removal rate of oil is 86.7 percent. It consumed 5.7 mg ozone to remove 1 mg oil. Most of the fatty acids produced during ozone oxidation were C2 and C3 acids. The oil content in effluents following ion exchange treatment was under detection limit. The result indicates that the combination of ozone oxidation and ion exchange could be utilized for reclamation of oily cooling water from oil refinery. |
