在石油生产过程中
含油污水产生量大、成分复杂且乳化程度高
给处理带来了很大挑战。气浮选工艺以其高效、操作简便、占地小及加药量低等优点
成为处理含油污水的理想选择。但传统单一气浮工艺在处理小粒径油滴时效果不佳
因此国内外学者对耦合气浮工艺开展了深入研究。聚焦气浮选与其他技术的耦合应用
系统梳理了传统气浮与旋流场、过滤系统、气泡萃取、纳米气泡及生物表面活性剂等技术的耦合研究进展
并深入讨论了油滴—气泡的相互作用机制及影响除油效率的关键因素
以期为进一步提高传统气浮工艺的除油效率提供指导。
Oily wastewater generated during petroleum production is characterized by large volume
complex composition
and a high degree of emulsification
posing significant challenges for treatment. Air flotation has become an effective technology for oily wastewater treatment owing to its high efficiency
operational simplicity
small footprint
and low chemical consumption. However
conventional single-stage flotation processes exhibit limited efficiency in removing small oil droplets. Consequently
extensive global research has been conducted on coupled flotation technologies. This study focuses on the synergistic integration of air flotation with other technologies
systematically reviewing recent advances in coupling conventional flotation with vortex flow fields
filtration systems
bubble extraction
nanobubbles
and biosurfactants. The interaction mechanisms between oil droplets and air bubbles are further examined
and the key factors influencing oil removal efficiency are discussed in detail. This study aims to provide guidance for further improving the oil removal efficiency of traditional dissolved air flotation processes.
