摘要
根据低渗透油田采出水的水质特性,设计一套微滤膜污水处理一体化撬装装置。该微滤膜污水处理装置在工艺上应用了微滤膜深度处理技术,并配套使用了絮凝沉降辅助工艺,解决了低渗透油田污水处理后回注不达标的问题。应用该微滤膜污水处理一体化撬装装置后,悬浮物含量、悬浮物颗粒粒径中值、油含量等指标均达到了规定要求。根据微滤深度处理的结果,分析了影响微滤的因素,研究了运行温度与压力对微滤处理效果的影响,并得到了金属膜过滤器的最佳运行温度和压力范围。
According to the characteristics of the water in low permeability oilfield,an integrated filter skid device is designed for wastewater treatment.Microfiltration membrane technology andauxiliary process of flocculation sedimentation are applied in this device.After using this device,the indexes including the content of suspended solids,the diameter of the suspended median particle and the content of oil meet the requirements of sewage reinjection in that oilfield.Then based on results of the microfiltration process,the factors which influence this process are analyzed.The effect of operating temperature and pressure is studied,and the optimum operating temperature and pressure of the metal membrane filter are obtained.
