摘　　要：三元驱采油污水由于碱溶蚀作用导致水中存在大量小颗粒无机硅,且p H显碱性,水体黏度高,不易于絮凝剂作用的发挥,水体Zeta电位低,更增加了絮凝难度。笔者利用室内烧杯试验通过Zeta电位变化筛选了无机聚合硫酸铁和有机絮凝剂UT6-4,并将二者进行正交复配试验,确定最佳复配比例为500∶40,此时,处理三元驱采油污水的絮凝除油效果最佳。The oily sewage of alkali-surfactant-polymer （ASP） flooding has higher suspended solids （SS） because of clay mineral dissolution by alkali. Both its higher viscosity and lower absolute value of Zeta potential make the flocculation more difficult. In this study, the combination of inorganic PFS and organic UT-4 with the optimal ratio of 500：40 as the compound flocculant leads to the best flocculation and oil removal efficiency for oily sewage of ASP.
