摘　　要：随着油田多年的开采,我国很多油田的发掘都已经进入了末期。国内各油田为了提高采油率,常见的开采方式为化学驱采油。化学驱采油同样有很多不足,若使用了错误的方法,含油污水会不断增加,同时也增加了分离难度。简要介绍了含聚污水的来源以及特征,并综述了目前常见的含聚污水处理方法,分为物理方法,如重力分离法,水力旋流法,聚结气浮法,加药气浮法;化学方法,如添加絮凝剂,水质改性技术,以及两种新型处理方法,如微生物法,微波辐射方法,提出了国内今后含聚污水的处理技术的发展方向。at present,with the development of oil fields for many years,the exploration of many oil fields in China has entered the late stage.In order to improve the oil recovery rate,the common way of exploitation is chemical flooding oil recovery.Chemical flooding also has many disadvantages,such as increasing the content of produced water containing polymers,which make it more difficult to separate oil from water.The sources and characteristics of poly wastewater were briefly introduced,and the common treatment methods of poly wastewater were summarized,which were divided into physical methods,such as gravity separation method,hydrocyclone method,coalescence air floatation method and medicated air floatation method.Chemical methods,such as adding flocculant,water quality modification technology,and two new treatment methods,such as microbial method and microwave radiation method,put forward the development direction of domestic treatment technology of poly wastewater in the future.
