摘　　要：目的:研究水处理系统中反渗膜及管路对透析用水质量的影响。方法:采用统一的透析调查表对2006年度长沙市20家透析单位进行调查。选择血液透析水处理系统易于取样又能代表水处理污染情况的4点(原水、反渗水1(配制B液取样点)、反渗水2(进入透析机前取样点)、透析器入口透析液取样点)采水样进行内毒素定性检测。结果:管路定期消毒时间的长短,水处理系统是否设计有储水罐,管路设计是否有死腔、死腔次环路、热消毒管道,以及反渗透膜的使用时间等,对透析用水及透析液的质量均有显著影响。结论:透析用水的卫生质量与水处理系统使用年限、是否及时更换和消毒、管路设计有无死腔与储水罐以及A、B液配制等有关;透析用水及透析液双级反渗优于单级反渗水处理系统。Objective To research the effect of reverse osmosis membrane and pipeline in water treatment system.Methods A formal questionnaire was prepared and accounted in 20 hospitals＇ Hemodialysis Centers in 2006 in Changsha.Four points of hemodialysis water of water treatment system were selected,which not only acquired easily but also represent polluted situation：tap water,reverse osmosis water 1（prepare B fluid sampling point）,reverse osmosis water 2（go into dialysis machine sampling point）,dialyser entrance dialysate sampling point,to detect endotoxin.Results The sanitary quality of the dialysate in hospitals was associated with the using time of water system,timely exchange and disinfection of the water treatment system,whether there were deep space and water storage tank in the channel design.Conclusion Double osmosis systems were superior to one osmosis systems in Hemodialysis system of water treatment system.
