摘要
高铁酸盐是一种集氧化、絮凝、杀菌多种功能为一体的新型高效多功能水处理剂,高铁酸盐水处理剂兼有较强的氧化性和优良的絮凝功能且在杀菌方面依旧表现优异,且相较于物理吸附法更不易产生二次污染,相较于传统氧化剂,高铁酸盐更为安全,在水处理领域有广阔的应用前景。与使用传统方法合成高铁酸盐相比,本文讨论了高铁酸盐的原位生成方法的优势及其在工业应用方面的价值;对于制约高铁酸盐工业应用发展的稳定性问题,文中分析了影响高铁酸盐稳定存在的温度,pH,溶液中所含有的各种离子浓度等各种因素,综述了提高固态和液态两种形式的高铁酸盐稳定性的方法;最后总结了高铁酸盐在水处理方面的应用进展,对于高铁酸盐工业推广应用中存在的问题进行了探讨。
Ferrate is a new efficient multi-functional water treatment agent integrating oxidation,flocculation and sterilization functions.Ferrate salt water treatment agent has both strong oxidation and excellent flocculation functions,and still performs well in sterilization.Compared with physical adsorption method,ferrate is less likely to cause secondary pollution.Compared with traditional oxidants,ferrate is safer and has broad application prospects in the field of water treatment.Compared with the traditional method of synthesizing ferrate,this paper discusses the advantages of the in-situ method of producing ferrate and its value in industrial application;For the stability problems that restrict the industrial application and development of ferrate,this paper analyzes various factors that affect the stable existence of ferrate,such as temperature,pH,concentration of various ions contained in the solution,and summarizes the methods to improve the stability of ferrate in solid and liquid forms;Finally,the application progress of ferrate in water treatment is summarized,and the problems in the industrial application of ferrate are discussed.
