含聚丙烯酰胺类采出水中聚合物降解的研究现状及发展

The research status and development of degradation of polyacrylamide polymers in oily wastewater

三次采油过程中形成的含聚丙烯酰胺污水粘度大,油水界面的水膜强度高,絮体生成与沉降慢,严重影响了采出液的油水分离效率、污水处理效果,提高污水中聚丙烯酰胺的降解效率对于确保含聚污水有效处理具有重要意义。本文对油田含聚污水中聚丙烯酰胺的化学降解、生物降解等机理进行了分析,并对其降解研究进展做了详细的总结和分析。

The sewage containing polyacrylamide in the process of tertiary oil recovery with the characteristics of high viscosity, high strength of oil aqueous interface,slow floc formation and settling,which seriously affected the extraction liquid of oil-water separation efficiency and effect of sewage treatment.To improve the degradation efficiency of the polyacrylamide in the sewage has important significance for the effective treatment of sewage containing polyacrylamide.In this paper,degradation mechanism of the chemical degradation and biode- gradation of polyacrylamide in the sewage containing polyacrylamide has been analysed,and study of the research progress has been summarized and analysed detailedly.
