含油污水除油净水技术研究与发展

目前全国大多数油田基本采用注水开发方式，随着油田进入高含水后期，采出水量也大幅增长；而油田采出水中不可避免地产生一些含油污水，出于环境保护和节约资源的考虑，如何经济、有效地对含油污水处理是目前油田可持续发展的关键。通过对近几年来国内含油污水处理的工艺流程、处理设备和处理药剂所作的一系列介绍，对现在困扰国内各油田的含油污水处理中存在的问题提供一些解决思路。

Treatment technology and research on oil-bearing sewage

Nowadays, most oilfields are often applied with waterflooding. As domes tic oilfields have entered highly water-bearing period, the amount of wastewater is increasing rapidly. Meanwhile, the oil-bearing wastewater has emerged unavoi dably in the effluent. In terms of environmental protection and resource saving, how to treat wastewater economically and effectively plays a key role on oilfie ld sustainable development. After brief introduction of the development of the n ew foreign and home equipment, reagent and process flow on the treatment of oil-bearing sewage, some new ideas and trend have been provided for solving the prob lems on oil-bearing sewage treatment, which have troubled every domestic oilfiel d.
