本文对卤代硝基甲烷（HNMs）的形成和控制进行了系统研究 这项研究。使用的消毒剂包括臭氧、氯、一氯胺和臭氧 其次是氯或一氯胺。未经处理（即进入处理厂的进水）和 处理过的水（即，在常规处理过程之后，但在添加任何 来自南卡罗来纳州（查尔斯顿、， 格林维尔、默特尔海滩、SJWD和斯巴达堡）在不同的地点进行了收集和调查 一年中有三次。结果表明，HNMs摩尔浓度（22- 67纳米）和摩尔 臭氧氯化处理的产率（10-40nm/DOC）最高，其次是 氯化、臭氧氧化、氯胺化和氯胺化处理 水域。在每个阶段，处理水的HNMs产量都高于原水 处理厂，表明常规处理工艺没有去除主要污染物 HNMs前体。结果表明，最亲水的NOM组分（HPI）是 未通过常规处理工艺去除的主要HNM前体。也是 发现HNMs产量随着DOC/DON比率的降低而增加（i。 e、 ，增加氮 水中每种有机碳的含量），以及含氮有机化合物，如 氨基糖或氨基酸是HNMs最可能的前体。看来DOC/DON 该比率可以作为公用事业公司评估天然和天然气中HNM前体存在的一种简单方法 净化水。包括13个参考文献、表格、图表。

A systematic investigation about both the formation and control of halonitromethanes (HNMs) were conducted in this study. The disinfectants applied included ozone, chlorine, monochloramine, and ozone followed by chlorine or monochloramine. Raw (i.e., the influents to the treatment plants) and treated waters (i.e., the water after conventional treatment processes but before any addition of disinfectants) from five drinking water treatment plants in South Carolina (Charleston, Greenville, Myrtle Beach, SJWD, and Spartanburg) were collected and investigated at different times in a year. The results showed that HNMs molar concentrations (22-67 nM) and molar yields (10-40 nM/DOC) were the highest by the treatment of ozonation-chlorination, followed by chlorination, ozonation-chloramination, and chloramination treatment in both raw and treated waters. Higher HNMs yields were observed in the treated water than the raw water at each treatment plant, indicating that the conventional treatment processes did not remove major HNMs precursors. The results suggest that the most hydrophilic NOM fractions (HPI) that are not removed by conventional treatment processes contain the major HNM precursors. It was also found that HNMs yields increased with decreasing DOC/DON ratios (i.e., increasing nitrogen content per organic carbon in water), and the nitrogenous organic compounds, such as aminosugars or amino acids, are the most likely precursors of HNMs. It appears that DOC/DON ratio can be a simple method for utilities to asses the presence of HNM precursors in natural and treated waters.
