| Abstract: | The treatment of petroleum wastewater using bulk electrolysis was investigated by synthetic boron-doped diamond(BDD) thin film electrodes to explore the influences of the time,tank voltage and the distance of electrodes on the rate of the degradation.The rate of the gradation is up to 93.9% after 5 hour's electrolysis when the voltage is 8 V and the distance of the electrodes is 2 mm in the experiment.We also carried out an experiment of instead of cathode.The mechanism of the degradation of the COD was analyzed at last. |

| Keywords: | BDD electrodes tank voltage COD the efficiency of the current |
