%X Electrocoagulation was applied to water produced with coal-bed methane treatment.Comparing aluminum and iron electrodes,the former one was selected in the electrocoagulation experiments.The effect of the operational parameters such as inter-electrode,the pH value and current density was investigated.The results showed that the electrocoagulation was an effective water treatment technique for water produced with coal-bed methane.The optimum working pH was found to be in the neutral condition,allowing water produced with coal-bed methane to be treated directly without adding soluble salts to the water and changing the pH of the solution.The appropriate experimental conditions for water produced with coal-bed methane treatment by electrocoagulation are quantified.Electrode distance is 1 cm.The current intensity is 30 A/m2.The COD and SS reach 9.6 mg/L and 8.5 mg/L after 10 min reaction,of which the removal efficiencies are about 75.1% and 88.8%,respectively.The pH value of effluent is 7.8.The power requirement is 1.75 kWh/m3.Experimental investigations show that the electrocoagulation is an effective water treatment technique for water produced with coal-bed methane.
