氧化-吸附法联合处理气田水

气田水的治理是油气田废水治理的难点之一,其处理方法较多。实验首次尝试采用双氧水氧化与活性炭吸附联合作用的方法处理川中遂121井气田水,并确定了最佳工艺条件。结果表明,该方法能有效降低气田水中污染物含量,COD(化学需氧量)去除率达81.8%。与先用双氧水氧化,然后用活性炭吸附分步法处理比较,该法不仅操作简单,节省时间,而且可以提高处理效果,值得推广应用。

COMBINATION OF OXIDATION AND ADSORPTION FOR TREATING WASTEWATER OF GAS FIELD

Treatment of wastewater of gas field is one of difficult treatment process. There are many ways to treat the wastewater. Gas field wastewater which comes from Chuanzhong Sui 121 has been treated by the combination method of H2O2oxidation and active carbon adsorption, and the optimal process con-dition has been determined. Results show that the content of contaminants has been reduced efficiently, and COD removal rate will reach 81. 8%. Compared with two-step method,namely first H2O2oxidation, then active carbon adsorption, this method can not only operate easily, save time, but also improve treatment effect, and deserve spread and application.
