In this paper the bio-treatment of sewage containing polyacrylamide(PAM) was studied preliminary.The sewage containing PAM is difficult to be treated,and the increasing sewage quantity in recent years will have a negative impact on the environments.The results of this study indicated that when the 7 PAM degrading bacteria that were separated from the sewage of oilfield cooperated with each other in the optimum medium they can biodegrade the sewage containing PAM effectively.After 3 days the COD of the sewage with additional phosphorus and nitrogen was deceased of 87.7%,after 18 days the COD was deceased from 13499 mg·L-1 to 283 mg·L-1 So the 7 PAM degrading PAM bacteria are very effective in PAM biodegradation and sewage treatment in oilfield.
