生物处理技术在采油废水治理中的应用

石油开采、获取过程中伴生的采油废水含有大量有机污染物质,对于环境可造成严重危害。目前,生物处理技术是水体污染治理过程中最常使用的技术手段,运用生物处理技术降解采油废水治理效果好,运行成本低。其类型主要包括活性污泥法、生物膜法、自然处理法及厌氧生物氧化法。对上述几类方法的研究进行了相应概述。

Application of Biological Method in Oil Extraction Wastewater Treatment

In the oil exploration and production process, there is oil extraction wastewater which contains large amounts of organic pollutants. So they can cause serious harm to the environment. Biological method is the most commonly used technology for water pollution. In the treatment process of the oil extraction wastewater, biological method has good effect and low operating cost. Its main types include activated sludge, biofilm, natural treatment method and anaerobic biological oxidation. In this paper, research situation of these methods was introduced.
