摘要：

通过反相微乳液法制备得到了固含量为40%~50%的P（AM-DMC）反相微乳液，并对产品结构进行了核磁及红外光谱表征。针对SAGD采出液深度处理热石灰软化工艺段污水对产品絮凝性能进行了研究，结果表明P（AM-DMC）反相微乳液具有良好的絮凝效果，优于现场絮凝药剂。阳离子度和相对分子质量分别约为22%和400万时絮凝效果最佳，投加质量浓度为3 mg/L的条件下可大幅度降低混凝剂的投加量，显著降低出水的浊度。

Abstract:

The P(AM-DMC) reverse microemulsion with solid content 40%-50% was synthesized by reverse microemulsion polymerization method. The product structure was characterized by ¹H NMR and IR. The flocculation property was researched with the SAGD production liquid in the hot lime softening process. The results showed that P(AM-DMC) with 4 million molar mass and 22% cationicity had best flocculation effect, which was better than onsite flocculating agent. When the dosage was 3 mg/L, it could reduce the dosage of coagulant greatly and reduce the turbidity of the effluent significantly.

Key words: reverse microemulsion, high solid content, flocculation, turbidity, emulsified oil
