超滤膜处理油田含油污水研究进展

Advances in oily wastewater treatment by ultrafiltration membranes

针对国内外油气工业中含油污水处理效率低、设备运行费用高的现状,介绍了超滤膜过滤的原理以及含油污水超滤膜处理技术,包括单一膜、复合膜、改性膜和共混膜以及超滤膜与其他方法的耦合工艺。最后,针对目前存在的问题提出了一些建议。

Given the present low efficiency and high operation cost in the oily wastewater treatment at domestic and abroad oil and gas industry, this paper introduces the filtration principle of uhrafiltration （UF） membrane and the treatment technology of oily wastewater by UF membrane, including single membrane, composite membrane, modified membrane and blend membrane as well as the coupling process of ultrafihration membrane and other methods. Finally, some suggestions are put forward for the existing problems.
