Abstract: It has been raised a new method, electrocoagulation in disposition of gas-field wastewater. The reacting mechanism and condign technological conditions have been studied in the lab.Results show that themain pollutantCODcrremoval rates of gas-field wastewater are 50% ~60% when take this technique as first-order reaction, while CODcrremoval rates can reach 70%~80% when as secondary reaction. In addition, this

Key words: gas - field wastewater, electrocoagulation, CODcr removal rates
