大港油田污水回用工程超滤反渗透设计

Design outline of ultrafiltration and reverse osmosis system for Dagang oil field wastewater reuse advanced treatment project

通过总结大港油田污水回用深度处理工程超滤反渗透系统设计思路,介绍了目前国际领先的"双膜法"污水回用深度处理技术。着重论述了该工程超滤反渗透单元以及各辅助系统如加药、反洗、化学清洗等系统的设计,研究并探讨了系统设计中膜污染问题的解决措施和思路。

The design outline of ultrafiltration and reverse osmosis system for Dagang oil field wastewater reuse advanced treatment project was summarized. The world leading dual membrane wastewater reuse treatment technology was introduced. The ultrafiltration and reverse osmosis unit, the design of the auxiliary system such as chemical dosing,backwashing and the chemical cleaning of the system were described in more detail. And the membrane fouling solutions were discussed by study on the practical system design to put forward some virtual references for similar projects.
