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
