【摘要】目的用现有的水处理系统制备出可持续使用的超纯透析用水。方法通过研究陕西省中医医院血液透析室透析用水中细菌、内毒素含量与消毒时间的关系，寻找细菌、内毒素达到超纯透析用水标准的时间节点，制定合理的水处理系统消毒周期。结果将水处理设备的消毒周期调整为1 个月可使透析用水中细菌、内毒素含量持续符合超纯水标准。结论通过优化消毒周期能够制备出可持续使用的超纯透析用水。

【Abstract】Objective To prepare sustainable ultra-pure dialysis water from existing water treatment systems. Methods Through the investigation on the relationship between number of bacterial colonies and endotoxin content in dialysis water and disinfection time of the water treatment systems in the Center for Hemodialysis of Shaanxi Traditional Chinese Medicine Hospital, we tried to find out the best disinfection cycle at which bacterial number and endotoxin content in dialysis water satisfy the standards, and then set up this disinfection cycle for water treatment systems. Results The disinfection cycle of water treatment systems can be
adjusted to one month to maintain the bacterial number and endotoxin content in dialysis water compliant with the ultra-pure water standards. Conclusions The disinfection cycle of the existing water treatment systems can be adjusted to obtain sustainable supply of ultra-pure dialysis water.
