摘要

自來水廠供水系統中加入氯和氯胺，對飲用水進行消毒，降低城市供水系統中細菌污染的風險。氯胺進入血液會導致透析患者發生慢性溶血性貧血、急性溶血與變性血紅素血症等疾病，血液透析用水必須將其降低至安全濃度以下，以確保透析患者的安全。使用活性碳去除自由氯和氯胺是透析用水設備不可或缺的重要過程。建議於每班透析治療前或原水水質改變時監測總氯濃度。其總氯最大濃度應小於0.1 mg/L，以確保透析用水安全無虞。

Chlorine and chloramine are added to the tap water supply system to disinfect drinking water and reduce the risk of bacterial contamination in urban water supply systems. The entry of chloramine into the blood can cause illnesses such as chronic hemolytic anemia, acute hemolysis and methemoglobinemia in dialysis patients. Hemodialysis water must be reduced chlorine to certain level to ensure the safety of dialysis patients. To use activated carbon to remove free chlorine and chloramine is an important process that is essential for dialysis water equipment. It is recommended to monitor the total chlorine concentration before each dialysis treatment or when the raw water quality changes. The maximum concentration of total chlorine should be less than 0.1 mg/L to ensure dialysis water is safe.
