摘要
综述了正渗透(FO)膜技术对废水中的氨氮回收的研究进展.重点介绍了其发展历史、工艺原理、应用现状,将应用现状分为膜制造和改性、膜与其它工艺的耦合工艺、提取液、膜污染、数学建模这五方面进行了综述.在此基础上,对正渗透膜技术的研究前景进行了展望.
Abstract
The research progress of forward osmosis(FO)membrane technology for ammonia nitrogen re-covery from wastewater is reviewed.The development of history,technical principle and application status were introduced emphatically,and the application status was summarized in five aspects:membrane manu-facturing and modification,coupling technologies between membrane and other technologies,draw solu-tion,membrane contamination and mathematical modeling.On this basis,the research prospect of forward osmotic membrane technology was prospected.
