油田采油废水处理含有浮油、乳化油和溶解油之外,还含有大量悬浮固体,以及开采过程加入的木质素、发泡剂、重晶石、粘土等,从而使废水成分即为复杂,为其处理工艺提出了很高的要求。本文就当油田采油废水的处理现状及存在问题进行了讨论,并且对几种常见的采油废水处理工艺进行了介绍,希望为采油废水处理工作提供一定的参考。 Oilfield wastewater treatment contains oil slick, emulsified oil and dissolved oil, but also contains a large amount of suspended solids, as well as lignin, foaming agent, barite and clay added in the mining process so as to make the composition of waste water complex The treatment process made a very high demand. This article discussed the current situation and existing problems of oilfield wastewater treatment, and introduced several common treatment methods of oil recovery wastewater. It is hoped to provide reference for the treatment of wastewater from oil production.
