摘要: 对油田日益增多而现有污水处理工艺难于处理的含聚合物污水进行生化处理室内模拟研究。结果表明,从聚合物驱油的采油废水中分离到的一组混合菌株加入到生化池中,通过加入激活剂,活化加入的聚合物降解菌,并激活污水中原有菌群,将生化工艺用于含聚合物污水处理具有较好的效果。经过菌群7d的处理,聚丙烯酰胺质量浓度从47.42mg/L降为5.78mg/L,含油量从13.5mg/L降为0mg/L,并有效抑制了硫酸盐还原菌的生长。

Abstract: A puzzle how to treat produced water containing polyacrylamide is presented while the polymer flooding technique is widely used.The feature of produced water containing polyacrylamide is highly viscous,plentiful of oil and stable for emulsified oil.It is hard for conventional processes and equipment to treat produced water containing polyacrylamide to make it reach the national standard for recycle water.In this research,produced water containing polyacrylamide is treated with bacilluses,which are cultivated from the Shengtuo Oilfield reservoir water.The result shows that the biochemical processes can be applied to the water produced,the content of PAM changes from 47.42mg/L to 5.78mg/L,the content of oil changes from 13.5mg/L to zero after 7 days′biotreatment,at the same time,the sulfate reducing bacteria can be restrained effectively.

Key words: produced water containing polyacrylamide, PAM, biochemical technique, degradation
