摘　　要：本文针对含聚合物采油废水中聚丙烯酰胺生物毒性大、生化降解困难,采用"二级气浮+活性污泥"工艺对高含聚采油废水进行了现场实验研究。实验结果表明,处理后外排水中COD 80 mg/L,降解效率96.9%;石油类2 mg/L,降解效率98.6%,外排水的各项指标均能达国家和地方的相关标准。This paper was aimed at the problem of polymer-bearing wastewater of extracting oil including polymer being difficult to discharge up to environmental standards because polyacrylamide in the wastewater is difficult to degrade and has great biologic toxicity.Secondary air float and activated sludge process were used to study the wastewater of extracting oil at Guwu Combined Station.The experimental result indicated that COD in processed wastewater could be degraded to about 80 mg/L,with a degradation rate of 96.9%,oil in processed wastewater could be degraded to 2 mg/L,with a degradation rate of 98.6%.Every index of processed wastewater could reach the national and cocal relevant standards.
