  • 摘要: 采用电絮凝法处理煤层气产出水，通过铁和铝2种电极材料的处理效果的比较，选择铝电极进行实验，研究了电极间距、原水pH值以及电流密度等因素对电絮凝处理效果的影响。实验结果表明，电絮凝法对煤层气产出水的化学需氧量（COD）和固体悬浮物（SS）具有良好的去除效果，原水pH接近中性时处理效果较好，电絮凝处理过程中不需添加可溶性盐和改变pH值。实验中确定的电絮凝处理条件为:电极间距1 cm，电流密度30 A/m2，反应10 min后，出水的COD、SS分别为9.6 mg/L和8.5 mg/L，去除率分别达到75.1%和88.8%，出水pH为7.8，电能消耗为1.75 kWh/m3。
    Abstract: 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.
