摘要
本文以膜生物反应器(MBR)工艺处理炼油废水为实例,分析了MBR膜污堵的几种现象和成因,对膜污堵清洗的方法及效果进行了研究总结。研究表明:通过针对性离线清洗,膜比通量平均可达到90%的水平,从而确保了MBR装置的长周期运行。
The phenomenon ＆ causes of MBR membranes fouling of MBR process treating refinery wastewater was analyzed and the methods ＆ effects of the membrane fouling offline cleaning program were summarized. The membrane flux ratio was capable of reaching 90% on average after the specific offline cleaning, therefore ensuring the MBR system to run in a longer term operation condition.
