摘要
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 heterogeneous mixture of organic materials commonly presented in natural waters.Different treatment methods have diverse influences on the removal of NOM and the safety of drinking water.Ozone had been used worldwide to treat drinking water in recent years.Therefore,it was of great significance to study the impact of ozonation on NOM in source waters.Characterization of NOM and the formation of disinfection by-products by ozonation of particular NOM fractions were introduced in this paper.It also summarized a number of improved methods based on ozonation and compared their relative merits.In the end,it provided new ideas for further development of highly-efficient and practical approaches to resolve problems caused by NOM in drinking source waters.
