摘　　要：采用模拟的含部分水解聚丙烯酰胺(HPAM)和一定矿化度的聚合物驱采出污水,以及无机絮凝剂聚合氯化铝(PAC)和有机絮凝剂阳离子聚丙烯酰胺(CPAM),研究了残留HPAM质量浓度对污水絮凝处理的影响.结果表明:在温度、PAC质量浓度相同的情况下,随着残留HPAM质量浓度增加,PAC和CPAM的处理效果显著下降;随着处理温度的升高,PAC的处理效果明显变好.通过与油田实际的聚驱采出污水处理比较,证实所采用的模拟聚驱污水具有参考价值.The effect of polyacrylamide residue on treatment of waste water was investigated with simulated water of polymer flooding reservoir in enhanced oil recovery and with certain hardness with the inorganic flocculant of polymerization aluminum chloride and organic flocculant cationic polyacrylamide. The results proved that the treatment effect drops remarkably with the increase of polymer residue in waste water at he same temperature and the same dosage of polymerization aluminum chloride and cationic organic flocculant. The treatment effect improves for polymerization aluminum chloride at increased temperature. Results by comparing with actual waste water from oil field proves that the simulated wasted water has reference value.
