旋流气浮分离技术在电脱盐切水处理中的应用

Application of Cyclone Air flotation separation technology in electric desalination and water cutting treatment

中国石油化工股份有限公司沧州分公司常减压装置处理原油时受原油来源地广且时常变化等多方面影响,导致电脱盐污水合格率偏低、油含量超标等问题,对装置环保运行及后续处理造成严重冲击,影响下游污水处理装置平稳运行。采用旋流溶气气浮技术可以有效降低污水油含量,保证电脱盐外排污水达标排放,具有很好的经济效益和环境效益。

The atmospheric and vacuum unit of China Petrochemical Corporation Cangzhou Branch is affected by various factors such as the wide range of crude oil sources and frequent changes in crude oil treatment,resulting in problems such as low pass rate of electric desalination wastewater and excessive oil content,which have a negative impact on the environmental protection operation of the unit and its follow-up. The treatment caused a serious impact and affected the smooth operation of the downstream sewage treatment plant. The use of Cyclonic Dissolved gas Flotation Unit technology can effectively reduce the oil content of sewage,and ensure that the discharge of electric desalination sewage meets the standards,which has good economic and environmental benefits.
