Polymer flooding has been widely used with the development of the technology. The quality standard of reinjection water after polymer injection changes accordingly, so the waste water treatment need to be adjusted, which makes it the new trend to develop new technology and process in oilfield waste water treatment.%随着油田聚驱技术开发的不断成熟，聚合物驱应用规模也在逐步扩大。油层注聚后回注水的水质标准也随之发生改变，因此污水处理工艺也应有所调整。开发新技术，应用新工艺将成为油田污水处理新的发展趋势。
