摘要： 目的  研究紫外线除氯装置用于血液透析水处理系统辅助除氯的效果。 方法 2022、2023年分别测试20组紫外线除氯装置关闭状态下北京大学第一医院水处理系统自来水、炭罐后的总氯浓度；紫外线除氯装置打开状态下自来水、紫外线除氯装置后、炭罐后的总氯浓度，并进行对比分析。 结果  紫外线除氯装置打开后，2022年和2023年自来水总氯平均下降率分别为75.0%和62.5%，装置前后总氯浓度差异显著(t=40.825，P＜0.001；t=46.483，P＜0.001)；与紫外线除氯装置关闭相比，2022年和2023年打开装置时碳罐A1(t=-8.365，P＜0.001；t=-17.474，P＜0.001)、A2(t=-6.718，P＜0.001；t=-16.905，P＜0.001)、B1(t=-8.014，P＜0.001；t=-12.212，P＜0.001)、B2(t=-6.162，P＜0.001；t=-13.789，P＜0.001)出口总氯浓度均有所下降。 结论  紫外线除氯装置除氯效果显著，可用于血液透析水处理系统。

Abstract: Objective To analyze the effect of ultraviolet dechlorination device used in hemodialysis water treatment system. Methods  Twenty groups of ultraviolet dechlorination devices in our hospital were tested in the years of 2022 and 2023. When the ultraviolet dechlorination device was closed, total chlorine concentrations in water supply and after carbon cans were measured. When the ultraviolet dechlorination device was opened, total chlorine concentrations in water supply, after ultraviolet dechlorination device, and after carbon cans were measured. The results were compared and analysed. Results When the ultraviolet dechlorination device was opened, total chlorine in water supply decreased significantly with the average reduction rates of 75.0% and 62.5% in 2022 and 2023 respectively (t=40.825, P<0.001; t=46.483, P<0.001). When the device was opened in 2022 and 2023, total chlorine concentrations at the outlet of activated carbon tanks A1(t=-8.365,   P<0.001; t=-17.474, P<0.001), A2 (t=-6.718, P<0.001; t=-16.905, P<0.001), B1 (t=-8.014, P<0.001; t=-12.212, P<0.001) and B2 (t=-6.162, P<0.001; t=-13.789, P<0.001) decreased significantly, as compared with those when the ultraviolet dechlorination device was closed.  Conclusion  Ultraviolet dechlorination device is effective and can be used in hemodialysis water treatment system.
