Abstract:
A group of mixed microbes which can grow and breed under the condition of 6000 mg/L mineralization degree for degrading polyacrylamide and oil have been chosen from oil field. The mixed microbes include 17 strains,13 of which are facultative anaerobic bacterium by isolating and identifying. The wastewater containing 100 mg/L of HPAM(hydrolyzed polyacrylamide) can be cultivated in the shaking box, and on the ninth day the removal rate of HPAMreaches 84%, and the removal rate of COD is 74.4%. The removal rates of HPAMand COD are 50.1% and 56.4%-62.2% respectively under the condition of treating 410 mL/h of wastewater with 150 mg/L of HPAM through micro organis mfilm experiment.

摘要：
从油田筛选到一组降解水解聚丙烯酰胺和石油的混合菌，能够在6000mg/L矿化度下生长，经过分离和菌种鉴定，发现混合菌由17株菌组成，其中有13株菌为兼性厌氧菌。摇床培养处理含100mg/L的HPAM(部分水解的聚丙烯酰胺)污水，第9天HPAM去除率达84.0%，COD去除率达74.1%。生物挂膜研究发现，在污水的处理量为410mL/h、HPAM的质量浓度为150mg/L时，HPAM的去除率为50.1%，COD去除率为56.4%～62.2%。
