Iron rod and carbon rod were used as anode materials to carry out comparative study.It was found that iron rod anode could supplement Fe2+ consumed in Fenton reaction of the reactor,the treatment effect was good,and the chemical properties were stable,so it was suitable for anode materials.Based on the comparative study of activated carbon,nickel foam and nano-iron particle electrodes,it was seen that 3 mm columnar activated carbon and nano-iron mixed particle electrodes had the best treatment effect on petroleum produced water.When the mixing ratio was 2∶1,the removal rate of COD was up to 80.37%,and the removal rate of oil was up to 86.29%.
