摘　　要：溶气气浮技术是饮用水处理行业常见的除藻技术,但由于其除藻效果受静电斥力、气泡尺寸等因素制约,已不能满足人们对水质的进一步要求。因此,强化气浮除藻及其联用工艺成为研究热点。文中从改性气浮(posi-DAF)、微纳米气泡技术、助浮剂强化气浮以及气浮与混凝、沉淀、过滤等工艺联用等方面,总结了国内外强化气浮除藻及其联用工艺的研究现状,并对其未来发展前景做出展望,以期为后续的研究与应用提供理论依据和技术支撑。Dissolved air flotation(DAF)is a common algae removal technology in drinking water treatment.However,the efficiency of algae removal is restricted by electrostatic repulsion,bubble size and other factors,which can not meet people’s further requirements for water quality.Therefore,enhanced DAF and combined technology have become a research hotspot.In this paper,research status of enhanced DAF and combined processes at home and abroad are summarized from the aspects of positive modification DAF(posi-DAF),micro-nanobubble technology,enhanced air floatation with flotation agents,and the combination of DAF with coagulation,sedimentation,filtration and other processes.And future development is prospected to provide theoretical basis and technical support for further research and application.
