| 摘 要： | 采取三维电极法处理钻井废水,考查了活性炭吸附作用、电解作用对COD去除率的影响,初步探索了三维电极法处理钻井废水的降解机理。利用正交实验分析了不同影响因素对COD去除率的影响程度。实验结果表明:三维电极系统对钻井废水的处理是电解和吸附作用协同效应的结果;活性炭感应荷电时处理效果最好;各因素对CODCr去除率的影响程度为初始CODCr浓度>电解时间>pH值>电流密度>电导率;最优水平组合为A4B4C2D3E4。

| Abstract: | Drilling waste water is treated by three-dimension-electrodes method.The electrolytic effect and the adsorption effect of active carbon on the removal rate of COD effects are studied.The degradation mechanism of drilling waste water treatment by three dimensional electrode method is preliminary discussed.Effects of different factors on the removal rate of COD influence degree are analyzed by orthogonal experiment.The results show: the CODcr of drilling waste water is reduced because of synergistic effect of electrolysis and adsorption in three-dimension-electrodes system.Activated carbon induction charging has the best effect.The factors on the removal rate of CODCr influence degree: initial CODcr of drilling wastewater>electrolysis time>pH>current density>electric conductivity.The best combination of experiment factors is A4B4C2D3E4. |
