A BENCH SCALE EXPERIMENTAL STUDY OF TREATMENT OF WASTEWATER FROM DELAYED COKING PLANT OF OIL REFINERY BY CATALYSIS AERATION MICRO ELECTROLYSIS PROCESS |

| Abstract: | A bench scale experimental study was conducted for treating the wastewater of high concentration from the delayed coking plant of an oil refinery by the catalysis aeration microelectrolysis process.The highlight of the study was put on the effect of the microelectrolysis and the influencing factors;and at the same time,the treating mechanism was discussed using the changing characteristics of the conductivity and redox potential(ORP). As a result,more complete parameters for a pilot test design and operation were given.The results show that the total removal rates of S 2- and COD Cr are over 90% and 68% respectively with the biodegradability improved greatly.Good result can be obtained from the treatment of the wastewater with high concentration from the oil refinery by this process. |
