油田开发废水深度处理技术的研究进展

摘要

The characteristics of current oilfield wastewater are reviewed. The principles and characteristics of advanced treatment of the wastewater, namely advanced oxidation processes (Fenton and Fenton-like methods, ozone method, photocatalytic oxidation method, supercritical water oxidation method and electrocatalytic oxidation method), flocculating setting method, membrane separation method, biochemical method and combined method, are summarized. The application progress for the oilfield wastewater treatment is discussed. The existing problems of the advanced treatments in the present research are pointed out. It is put forward that the combined application of the above several treatments is the development direction in the futural research.%概述了目前我国油田开发废水的特征,重点综述了高级氧化法(包括Fenton法及类Fenton法、臭氧法、光催化氧化法、超临界水氧化法和电催化氧化法)、絮凝沉降法、膜分离法、生物化学法和组合工艺等深度处理方法的原理、特点及近年来在油田开发废水处理中的研究进展,指出了目前每种技术存在的问题,最后提出几种处理工艺联合应用将是今后该领域研究的发展方向.
