高级氧化技术在油田水处理中的应用

Application Prospect of Advanced Oxidation Technologies for Produced Water Treatment

概述了高级氧化技术的基本原理和发展历程,介绍了臭氧氧化、二氧化氯氧化及光催化氧化等典型的高级氧化技术及其在水处理中的应用进展情况。结合目前油田水处理中出现的新问题,如硫酸盐还原菌含量高、有机物浓度高、微生物易于繁殖以及结垢严重等现象,对高级氧化技术在油田水处理中的应用前景进行了论述。同时提出应进一步加强对油田采出污水杀菌、油田水的灭藻和除泥、油田地面水体油污染控制等方面的研究。

The basic principle and phylogeny of some advanced oxidation technologies were described. Several typical oxidation technologies including ozone oxidation, chlorine dioxide oxidation and photocatalysis oxidation as well as their application to water treatment were introduced. Aimed at resolving some new problems in produced water treatment such as high content of reducing bacteria in sulphate, high concentration of organic substance, easily propagation of microbes and serious scaling, the prospect of the advanced oxidation technologies applied to treatment of the produced water in oilfield was discussed.
