摘　　要：管道直饮水(管道净水)是目前提高我国城市居民饮水健康最经济有效的方法。国内某高校为保证师生员工的饮水健康和饮水安全,在全校范围内建设了管道直饮水生产和供水系统。该直饮水系统规模为60 m^(3)/d,主体净水工艺采用“纳滤—微电解+紫外杀菌”,项目总投资为480万元,制水成本约为15元/m^(3),出水浊度为0.05 NTU、COD_(Mn)<0.5 mg/L、三氯甲烷<0.01 mg/L、总溶解性固体(TDS)约为50 mg/L,各项指标均优于《饮用净水水质标准》(CJ 94—2005)。Pipeline direct drinking water (pipeline purified water) is currently the most economical and effective method to improve the drinking water health of urban residents in China.A comprehensive pipeline direct drinking water production and distribution system was constructed throughout the entire campus of a domestic university,so as to ensure the health and safety of drinking water for teachers and students staff.The scale of the direct-drinking water system is 60 m^(3)/d,and the main water purification process consists of nanofiltration,micro-electrolysis and UV sterilization.The total investment of the project is approximately 4.8 million yuan,and the direct cost is 15 yuan/m^(3).The turbidity in effluent is less than 0.05 NTU,the COD_(Mn) in effluent is less than 0.5 mg/L,the trichloromethane in effluent is less than 0.01 mg/L,and the total dissolved solids (TDS) is approximately 50 mg/L,indicating that all indicators are better than the limit specified in Water Quality Standards for Fine Drinking Water (CJ 94-2005).
