摘要: 含聚丙烯酰胺采油污水的有效处理是近年来困扰油田三次采油生产的一个难题。研究采用移动床生物膜技术与O3/UV/H2O2高级氧化技术的组合方法来处理含聚丙烯酰胺采油污水。实验结果表明,移动床生物膜技术可以有效去除污水中的石油类有机物,但对聚丙烯酰胺几乎无效果。O3/UV/H2O2高级氧化技术可以降解污水中的聚丙烯酰胺。组合方法处理后的含聚丙烯酰胺采油污水水质可以达到污水综合排放标准中的一级要求。

Abstract: How to treat oil recovery wastewater containing polyacrylimide efficiently is a difficult problem in tertiary oil recovery production in recent years. A combined process with mobilebed biomembrane reactor and O3/UV/H2O2 oxidation for treatment of oil recovery wastewater containing polyacrylimide was studied. Experimental results showed that mobilebed biomembrane reactor could remove oil carbonates in the wastewater efficiently, but it had almost no effect on polyacrylimide. O3/UV/H2O2 oxidation could degrade and eliminate polyacrylimide.The water quality of oil recovery wastewater containing polyacrylimide treated by the combined process can meet the requirement of first level in wastewater general discharged standard. -
