由于一氯胺不与腐殖物质起反应形成三卤甲烷,所以用它代替氯对供水消毒已成为很受欢迎的方法。然而,最近在对病人进行肾分析中,发现氯胺能引起溶血性贫血。对伊利诺斯州的自来水进行了研究,测定当进水使用典型的一氯胺浓度时,粒径、接触时间和溶解有机物对炭柱进水浓度的影响。所得的数据对最佳炭柱的设计提供很好的估计,但是在得到更多的数据之前,必须对用于去除一氯胺的去氯装置进行仔细监测,以保证产生理想水质的水。
Since monochloramine does not react with humic substances to form trihalomethanes, it has become a very popular method to use it instead of chlorine to disinfect water supplies. However, in a recent renal analysis of patients, chloramine was found to cause hemolytic anemia. A study was conducted of tap water in Illinois to determine the effect of particle size, contact time, and dissolved organics on the influent concentration of the carbon column when using typical monochloramine concentrations in the influent. The resulting data provides a good estimate of the optimum design of the carbon column, but before getting more data, the dechlorination unit used to remove monochloramine must be carefully monitored to ensure that the desired water quality is achieved.
