Abstract

With the continuous development of industry, it is urgent to treat oily sewage to achieve resource recovery and utilization. For oily sewage, superwetting materials have become one of the most promising materials for treating oily sewage, owing to their high separation efficiency and low energy consumption. Among various treatment methods, the membrane separation method becomes one of the most popular treatment methods in the future because of its low energy consumption and environmental protection. In this work, the basic theory of membrane surface wettability and the preparation method of superhydrophobic surfaces was reviewed, and the research status of the use of superwetting membrane materials for the treatment of various types of oily sewage was further elaborated. At last, the prospects for those future development trends were forecasted.
