-
摘要: 高铁酸盐是一种集氧化、消毒和絮凝等多功能于一体的水处理剂,具有广阔的应用前景。综述了高铁酸盐在消毒方面的研究进展,包括高铁酸盐对细菌和病毒的灭活特性及影响消毒效果的主要因素,并将高铁酸盐与氯、臭氧等常规消毒技术在消毒效果、消毒机理、消毒副产物生成量等方面进行了详细比较。高铁酸盐在较宽的pH范围内对不同水体中的细菌和病毒均呈现较好的灭活效果,pH、温度和有机物是影响高铁酸盐消毒效果的重要因素,高铁酸盐和其他消毒技术联用将是未来研究的关注点。Abstract: Ferrate is a water treatment agent with multi-functions such as oxidation, disinfection and flocculation etc., which has broad application prospect. This paper reviewed the research progress of ferrate in disinfection, including the inactivation characteristics of ferrate to bacteria and viruses and its influencing factors, and compared it with other disinfection technologies in terms of disinfection efficacy, disinfection mechanism and the formation of disinfection byproducts. Ferrate had good inactivation effect on bacteria and viruses in different water bodies within a wide pH range. pH, temperature and organic matters were important factors affecting the disinfection effect of ferrate. The combination of ferrate and other disinfection technologies will be the focus of future research.
