摘要
综述了气浮技术在油田污水处理中的国内外发展进程。气浮过程中是否能生成有效的气泡对气浮效果起关键作用,根据产生气泡的方式对气浮技术进行分类并对其的优缺点进行对比。阐述了气浮技术在油田污水处理过程中的机理,并对应各机理介绍了几种常用且有效的气浮设备,最后根据各气浮方法讨论了气浮技术的研究方向。
The development of the floatation used in the wastewater treatment in the oil_field was summa rized. It＇ s crucial to produce some bubbles which are valid for the floatation effect during the floatation process. Making a classification of the floatation according to the way of producing bubbles and then com- paring each method of their advantages and disadvantages. The mechanism of floatation has been elabora- ted, and subsequently introduced some floatation instrument that in common use on the basis of the mech- anism. At last, taking about several study direction in floatation.
