- Abstract:
- A combined process of oxidation and ceramic membrane filtration was applied for the treatment of supernatant from coagulation pretreatment of an oil field produced water in Tianjin, and the treatment performances of H2O2, NaClO and O3 combined with ceramic membrane were compared. O3 had the best oxidation performance. When the dosage of O3 was 80 mg/L, the turbidity, petroleum substances, COD, DOC, UV254 and fluorescent organic substances removal efficiencies of the combined process reached 99.69%, 86.52%, 71.03%, 46.02%, 58.79% and 94.14%, respectively. In addition, there was a synergistic effect between O3 and ceramic membrane. Ozone oxidation catalyzed by nano?ceramic membrane improved the degradation efficiency of organic pollutants, and O3 effectively alleviated the fouling of ceramic membrane. The application of O3 and ceramic membrane combined process in petrochemical wastewater treatment has high technical feasibility and application value.
