摘　　要：为了解决低温含油污水处理的难题,采用环氧氯丙烷开环聚合、二甲胺季胺化的方法合成阳离子净水剂CY-16.现场污水处理评价实验结果表明:与油田一些常用的净水剂相比,CY-16净水效果好、成本低.在投加15mg.L-1CY-16+5mg.L-1HPAM、水温20℃和沉降30min的条件下,处理后的水中含油量不超过10mg.L-1,悬浮物含量不超过15mg.L-1,悬浮物粒径平均中值也降至3.0μm左右.Cationic polymer CY-16 was synthesized to solve the problem of low-temperature oily wastewater. A series of evaluation tests with fresh wastewater demonstrated that, compared to other wastewater treatment chemicals often used in oilfields, CY-16 can achieve high efficiency both on oil removal and on suspended solids （SS） at extensively low cost. Under the condition of 15 mg·L^-1 CY-16 ＋ 5 mg·L^-1 HPAM, water temperature 25℃, and sedimentation time 30 min, the final mass concentration of oil in treated wastewater decreased to no more than 10 mg·L^-1, that of SS no more than 30 mg·L^-1, and the median particle size of SS about 3.0μm.
