摘要: 以对含聚污水进行深度处理、满足回注为思路,数值模拟研究含聚污水经普通处理后进一步开展深度过滤处理的可行性及潜力。通过分析比较过滤流场的油珠及悬浮物粒子聚集分布、过滤出水水质含油与悬浮物质量浓度变化,以及除油率和悬浮物去除率的定量,构建并优化了适合于含聚污水压力式深度过滤的工艺模式。结果表明,“双层级配滤料+三层级配滤料”两级深度过滤工艺模式可依靠水力、界面效应实现进一步截污,再现出稳定的过滤性能,综合除油率和悬浮物去除率分别达到87.78%和87.11%,滤后水质的含油、悬浮物指标均可控制在深度处理水源要求的5 mg/L以内,是含聚污水深度处理的一种潜在过滤工艺模式,为有效应对油田化学驱三次采油开发中的水质问题提供了依据。

Abstract: It was proposed that the advanced⁃treatment of polymer⁃flooding produced water and realized the re⁃injection requirements. The feasibility and potential of further deep filtration treatment of wastewater containing polymer after ordinary treatment were studied by numerical simulation. The available advanced⁃filtration process pattern was established and optimized based on the distribution of oil droplets and suspended solid particles, the concentrations oil and suspended solid in filtered water, and the removal rates of oil and suspended solid. The results indicated that the advanced⁃filtration process pattern with "double graded⁃media + three graded⁃media" could further improve filtration performance depended on hydraulic and interfacial effects. The removal rates of oil and suspended solid reached 87.78% and 87.11%, respectively. The oil content and suspended solids of filtered water were controlled within 5 mg/L required for deep water treatment. This is a potential filtration process model for advanced treatment of polymer⁃containing wastewater, and also provides a basis for effectively dealing with water quality problems in tertiary oil recovery by chemical flooding in oilfields.
