油水分离技术进展

摘要

简述五种传统油水分离技术(重力沉降法、液-液旋流法、气浮法、聚结法与吸附法)以及三种新型油水分离技术,包括膜分离、冷冻/解冻分离和原位抽取分离.研究认为制备出低成本、无二次污染的超疏水/超亲油PHOMs将是研究热点之一.%Five kinds of traditional technologies of oil-water separation (such as gravity separation,liquid-liquid separation,air flotation,coalescence separation and adsorption separation) are summarized and three novel technologies of oil-water separation,including membrane separation,freeze-thaw separation and situ extraction separation are also concluded.Preparation of superhydrophobic/super hydrophilic PHOMs with low cost and no-secondary pollution will be one of the research hot spots in the future.
