摘要
为了满足电渗析的进水要求,用超滤装置对大庆油田含油废水进行预处理.结果表明,超滤膜滤出水的含油量和悬浮物均小于1.5 mg/L,去除率可达到94%,浊度低于1.0 ntu,去除率达到90%以上,达到了电渗析的进水要求.同时对超滤膜的清洗进行了实验研究.
In order to meet with the demand of influent of electrodialysis, uhrafiltration is chosen as the pre-treatment process of electrodialysis instrument. The results demonstrate that oil and suspended solid in treated water by UF is less than 1.5 mg/L respectively （95% of removal efficiency）, turbidity is as low as 1.0 ntu（ over 90% of removal efficiency）, the reliable operation of ED could be ensured. During the experimentation, the method for cleaning fouling membrane is studied.
