摘要
针对三元复合驱采出水p H值高、粘度大、高含油、SS浓度高、可生化性差等特点,选择气浮/水解酸化/生物接触氧化/砂滤组合工艺对其进行处理,经调试运行稳定后,出水悬浮物、含油量满足"双20"高渗透油层回注水水质标准。该组合工艺运行稳定,管理方便,处理效果好,运行费用低。
According to the characteristics of ASP flooding produced water, such as high pH, vis- cosity, oil content and poor biodegradability, the combined process of air floating, hydrolysis acidifica- tion, biological contact oxidation and filtration was used for its treatment. After the combined process op- erated stably, the concentrations of SS and oil content in effluent could meet the standard of high permea- bility reservoir injection water. The combined process has advantages such as running stability, convenient management, good treatment effect and low operating cost.
