摘要
铁在人们的生活中随处可见并且运用十分广泛,另外铁元素也是人体所必须的微量元素。铁在自然界中拥有多种价态,不同的价态展现出不同的化学性质,铁以其独特多样的化学性质在污废水处理中得到了广泛的应用。当前水处理技术方法朝多元化发展,主要从物理、化学和生物三方面进行结合和延伸。目前以铁元素为核心的零价铁(ZVI)、Fenton高级氧化工艺、铁碳微电解法和铁尾矿在污水的处理应用中得到了快速的发展并取得了丰硕的研究成果。综述了以铁衍生出的物理化学方法在污废水处理中的应用机制,并对其未来发展前景进行探讨和展望。
Iron can be seen everywhere in people’s lives and is widely used.In addition,iron is also a trace element necessary for the human body.Iron has a variety of valence states in nature,and different valence states exhibit different chemical properties.With its unique and diverse chemical properties,iron has been widely used in wastewater treatment.The current water treatment technology and methods are developing towards diversification,mainly combining and extending from the three aspects of physics,chemistry and biology.At present,zero-valent iron(ZVI)with iron as the core,Fenton advanced oxidation process,iron-carbon micro-electrolysis and iron tailings have been rapidly developed and obtained fruitful research results in sewage treatment applications.The application mechanism of physical and chemical methods derived from iron in sewage and wastewater treatment is reviewed,and its future development prospects are reviewed.Discussion and outlook.
