摘　　要：概述了油田污水的组成特点,并从近年来聚合物驱油和三元复合驱油产生污水带来的新问题出发,阐述了油田污水处理的难点所在。同时对当前油田污水处理工艺流程特点、实际工艺中存在的不足等作了比较,得出当前油田污水处理过程中工艺流程的选择标准和目标。重点对工艺处理中的絮凝沉降、生化处理以及膜法处理等不同的工艺流程中COD的去除进行了研究,通过比较各种方法得出在油田污水处理中利用生化法和膜处理方法的有机结合将是油田污水处理的主要发展方向。同时对当前油田污水处理中亟待需要解决的问题作了进一步表述。The composition of oilfield wastewater is briefly introduced, and the difficulty in the wastewater treatment is dicussed, especialy that derived from the polymer flooding and alkali-surfactant-polymer flooding techniques widely used in recent years. The characteristics of the wastewater treatment technological processes are described, and their shortcomings in practical application are compared, through which the criterion and target for the process of oilfield wastewater treatment are obtained. Especially, the removal of COD in different treatment processes is discussed and compared, including flocculating setting, biological treatment and membrane treatment. It is suggested that the combination of biological method with membrane technique would be the major trend for oilfield wastewater treatment. Finally, the urgent issues that needed to be resolved in the disposal of oilfield wastewater are described.
