摘　　要：对聚合物驱油田含聚废水生物处理现状进行了综述。讨论了包括腐生菌和硫酸盐还原菌在内的细菌降解聚丙烯酰胺分子的机理。指出可降解聚丙烯酰胺的细菌可从环境分离,也可采用生物强化技术获得。逐一介绍了文献报道的可降解聚丙烯酰胺的各种单一菌株和混合菌株及处理含聚废水的效果。图2参29。The present state of biological treatment of wastewaters containing （hydrolyzed） polyacrylamides and produced in polymer flooded oil fields is reviewed. The molecular mechanisms involved in degradation of polyacrylamides by various kinds of bacteria including total growth bacteria and sulfate reducing bacteria are presented. Two ways are available to obtain polyacrylamide degrading bacteria： extraction from the environment and bioaugmentation. The strains, individual and mixed, of polyacrylamide degrading bacteria published in literature recently and their biological efficieny are summarized.
