中文摘要：

低强度旋流离心力场与气浮组合是一种高效的含油污水处理技术,目前在国外已有较为成熟的产品,尤其是挪威M-I SWACO公司开发的Epcon紧凑型气浮装置已经在海上油田含油污水处理的应用方面取得了众多成功的案例。从Epcon紧凑型气浮装置的基本结构及其工作原理入手,简要叙述了该设备的工艺流程和性能特点,重点介绍了其在世界范围内尤其是在中国西江30-2采油平台上的测试和应用状况,最后介绍了新一代CFU设备的研发动向,为国内自主设计研发含油污水旋流气浮一体化处理设备提供必要的理论指导。

英文摘要：

The combined soft cyclone and flotation separation technology is an efficient produced water treatment method,and there are some mature products based on this kind of advanced technology.The Epcon Compact Flotation Unit（CFU）,invented by Norway M-I SWACO,has achieved a number of successful application cases around the world.The structure and principle of the CFU device were introduced firstly,and then the process flow and features were described.It was important to emphasize the pilot trials and application of CFU on XJ30-2 China,and finally introduced the latest CFU productions.All these work supplied a necessarily theoretical guidance for the design and research CFU independently in domestic.
