高铁酸盐预氧化技术在饮用水处理中的应用

Application of Ferrate(Ⅵ) Salts Per-oxidation Technique in Drinking Water Treatment

高铁酸盐作为一种集消毒、氧化、絮凝、吸附以及助凝为一体的新型多功能水处理药剂,最终产物不会产生二次污染,具有重要的研究开发和推广应用前景。文章综述了高铁酸盐作为预氧化剂在饮用水处理中的多种作用,包括其对藻类、有机污染物、金属离子、浊度以及微生物的去除效果及机理,同时对其在饮用水处理上的优势以及推广应用中的问题作了简单的分析。

As a novel multi-purpose water treatment medicament,the ferrate integrates the functions with disinfection,oxidation,flocculation,adsorption as well as coagulation aid,and its final products are of no secondary pollution,which makes it have significant research and development as well as potential application prospect.This article summarized the effects of ferrate in drinking water treatment as a pre-oxidation,including its elimination effects and the mechanism to the algae,the organic pollutant,the metallic ion,the turbidity and microorganism,simultaneously,several simple analysis were made on the superiority in drinking water treatment and questions in popularization and application.
