摘　　要：用絮凝剂二甲基二烯丙基氯化铵(DMDAAC)的均聚物和共聚物处理了模拟油田聚驱污水.考察了影响絮凝效果的因素,并进行了与无机絮凝剂的复配研究.实验结果表明:DMDAAC的均聚物和共聚物的最佳絮凝温度分别为30℃和33℃;最佳投药量范围与污水中部分水解聚丙烯酰胺浓度有关;残留聚合物含量低,阳离子度高时,絮凝效果较好;与聚合氯化铝(PAC)的复配可以实现优势互补,达到较理想的聚驱污水处理效果.Simulated oily waste water produced from polymer flooding have been treated by using the flocculant copolymer and homopolymer of DMDAAC. The influencing factors and the use with inorganic flocculant have also been investigated. The experimental results show that the optimal flocculation temperature of two titled flocculants are 30 ℃ and 33℃, respectively; The optimal do.sages are associated with the concentration of partly-hydrolyzed polyacrylamide residues retained in waste water; The floccu- lation performance is improved when the polymer content is lower and the cationicity is greater; With PAC, it can realize the complementation of their advantages, and can achieve the ideal flocculation performance.
