摘　　要：对油田日益增多的并且对环境造成潜在危害的而现有污水处理工艺难于处理的含聚合物污水进行微生物处理初步研究。结果表明,从油田污水污泥中分离得到的七株聚丙烯酰胺(PAM)降解菌在合适的营养条件下协同作用,对大港油田的含PAM的污水具有较好的处理效果。经过3d的处理,微生物菌群将补充了磷和氮的污水的COD降低了87.7%;经过18d的处理,微生物菌群将补充了磷的污水的COD由13499mg.L-1降低为283 mg.L-1,降低幅度达到了97.9%。因而这7株PAM降解菌对含PAM污水处理具有很好的应用前景。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 13 499 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.
