摘要： 目的  明确透析用水预处理系统中影响除氯性能的决定性因素。 方法 从2020年1月～9月的235个透析日，分别对自来水进水、树脂罐、炭罐1、炭罐2及反渗水的5个采样点的总氯浓度、pH值和水温进行采样监测。采用Pearson相关性分析衡量炭罐1后总氯水平与自来水总氯、pH、水温的相关性，并使用线性逐步回归(向后)分析探究具体的相关关系。 结果 炭罐1后总氯与自来水水温(r=-0.936， P＜0.001)呈负相关关系；与自来水pH(r=0.360，P＜0.001)、自来水总氯(r=0.235，P＜0.001)均存在正相关关系。逐步线性回归分析显示自来水水温与炭罐1后总氯水平呈负相关关系(𝛽=-0.936，P＜0.001)。 结论 自来水水温是透析用水预处理系统中影响除氯性能的决定性因素。季节性的自来水低温影响了透析中心预处理活性炭罐的除氯效率。

Abstract: Objective To clarify the decisive factors affecting the dechlorination performance in the pretreatment system of dialysis water.  Methods Total chlorine concentration, pH and water temperature were monitored in the 5 samples from tap water at input site, resin tank, carbon tank 1, carbon tank 2 and reverse osmotic water in a total of 235 dialysis days from January to September 2020. Pearson correlation analysis was used to investigate the correlation between total chlorine level behind carbon tank 1 and total chlorine, pH and temperature in tap water. Stepwise linear regression (backward) analysis was used to explore the specific correlation.  Results  The total chlorine behind carbon tank 1 was negatively correlated with tap water temperature (r=-0.936, P<0.001), and positively correlated with pH (r=0.360, P<0.001) and total chlorine (r=0.235, P<0.001) in tap water. Stepwise linear regression analysis showed that tap water temperature was negatively correlated with the total chlorine level behind carbon tank 1 (𝛽=-0.936, P<0.001).  Conclusion  Tap water temperature is the decisive factor affecting the dechlorination performance in the pretreatment system of dialysis water. Seasonal low temperature of tap water affected the dechlorination efficiency by the activated carbon tank in the water pretreatment system.
