摘要
综述了目前采油污水处理技术。指出回注水的处理方法主要有混凝法、隔油法、过滤法等物化方法,重点是去除污水中的颗粒物质;另外指明,外排水的处理方法主要是生化法及化学法,重点是降低水中的 COD。对目前存在的处理难点做出了分析,并提出了采油污水处理技术的发展趋势。
Summarizes the treatment technology of oil extraction wastewater at present. It points out that the main treatment methods of reinjection water are physicochemical methods such as coagulation, oil removal, filtration and so on. The important aim was removing grain from wastewater. It is illustrated that the treatment methods of discharged water are biochemical methods and chemical methods. Its difficulties of treatment are analyzed. It indicates the development tendency of treatment technology of oil extraction wastewater.
