| Abstract: | In the disposal of fracturing flow-back fluid in West Sichuan oilfield, micro electrolysis has been used as treatment method. In micro electrolysis reaction, the main factors related to chemical oxygen demand （COD） include the ratio of Fe and C, the pH value, the ratio of stuffing and water, the ratio of stuffing and catalyst and the reaction time. A preferable process has been selected by experiments study, and the stwely shows that： the ratio of Fe and C is 4：1 ; the pH value is 2; the ratio of stuffing and water is 1：1 ; the reaction time is 3-4 hour; the ratio of stuffing and catalyst is 12：1. |
