一氯胺因不与腐殖物质反应生成三卤甲烷而成为供水消毒中常用的氯替代品。然而，最近发现氯胺会导致肾透析患者发生溶血性贫血。对伊利诺伊州香槟市的自来水进行了一项研究，以确定当使用典型的进水一氯胺浓度时，颗粒大小、接触时间和溶解有机物对碳柱出水浓度的影响。由此产生的数据可以很好地估计碳柱的最佳设计，但在获得更多数据之前，应仔细监测用于去除一氯胺的脱氯装置，以确保生产出所需质量的水。 包括13个参考文献、表格、图表。

Monochloramine is becoming a popular alternative to chlorine for disinfection of water supplies because it does not react with humic substances to form trihalomethanes. However, chloramines have recently been found to cause hemolytic anemia in patients undergoing kidney dialysis. A study of Urbana-Champaign, Illinois, tap water was carried out to determine the effects of particle size, contact time, and dissolved organic matter on carbon column effluent concentration when a typical influent monochloramine concentration was used. The resulting data allow a good estimate to be made of the best design for a carbon column, but until more data become available, dechlorination units that are being used for the removal of monochloramines should be carefully monitored to ensure that water of the desired quality is being produced.
