Abstract:

Aiming at the water quality characteristics of oil-bearing wastewater from some offshore drilling platforms in Bohai Oilfield,the wastewater has been treated by NaOH demulsification-coagulation-flocculation process at room temperature. The water quality of effluent can meet the requirements of the influent in next unit,and provide a relatively good influent conditions for further advanced treatment. In addition,this method possesses strong adaptability to the variability of inflow water quality.

Key words: oil-bearing wastewater, demulsification, coagulation, flocculation

摘要：

渤海油田某些海上钻井平台含油废水的水质特点，在室温条件下采用NaOH破乳-混凝-絮凝方法对其进行处理，出水水质可满足下一单元的进水要求，为进一步深度处理提供了较为良好的进水条件，同时该方法对来水水质的多变性具有很强的适应性。
