天然有机物(NOM)是普遍存在于自然水体中的一类复杂的有机混合物,不同处理方法对原水中NOM的去除情况不同,这对饮用水的安全性也有较大影响。臭氧氧化是近年来饮用水处理中常用的消毒方法,因此,研究臭氧氧化对饮用水原水中NOM的影响有着重要的意义。介绍了NOM的分类方法以及臭氧氧化对每种NOM组分的作用,分析了臭氧氧化NOM对饮用水消毒副产物生成的影响。同时,总结了一些以臭氧氧化为基础的改进处理方法,对比分析了它们的优缺点,并为以后的研究工作提出了建议和展望。
Natural organic matter (NOM) is a complex organic mixture commonly found in natural water. Different treatment methods have different effects on the removal of NOM in raw water, which also has a significant impact on the safety of drinking water. Ozone oxidation is a commonly used disinfection method in drinking water treatment in recent years. Therefore, it is of great significance to study the effect of ozone oxidation on NOM in drinking water. The classification methods of NOM and the effects of ozone oxidation on each NOM component were introduced. The effects of ozone oxidation NOM on the generation of drinking water disinfection byproducts were analyzed. At the same time, some improved methods based on ozone oxidation were summarized, their advantages and disadvantages were analyzed and compared, and suggestions and prospects for future research were put forward.
