饮用水处理装置（POU-DWTU）在世界上许多地方都有广泛的应用。本文介绍了伊朗（库姆省）POU-DWTU的运行情况，并讨论了存在的问题和可能的健康相关方面。所研究的装置由初级过滤器、活性炭过滤器、反渗透膜和储罐组成。在一项横断面研究中，收集并分析了240个来自不同POU-DWTU输入和输出的水样。一半的POU-DWTU用户没有正确的操作原理的信息，其中35%的人不满意的味道和气味的处理水。分析表明，POU-DWTU能够将溶解固体含量降低90%以上，并产生软水。然而，POU-DWTU去除的重金属量变化从5%的Al到86%的Cd，其平均去除率为43%。原水和处理后的水中铅浓度均明显偏高。这是福...
ABSTRACTApplications of Point-of-Use Drinking Water Treatment Units (POU-DWTUs) are common in many parts of the world. This paper presents the operational conditions of POU-DWTUs in Iran (Qom province) as a case and discuses the problems and the possible health-related aspects. The devices which were studied consisted of primary filter, carbon filter, Reverse Osmosis membrane, and storage tank. During a cross sectional study, 240 water samples from the input and output of different POU-DWTUs were collected and analyzed. Half of POU-DWTUs users did not have correct information about the operational principles and 35% of them were not satisfied about taste and odor of the treated water. Analysis showed that POU-DWTUs were able to reduce the dissolved solids content more than 90% and produced soft water. However the amount of heavy metals removed by POU-DWTUs varied from 5% for Al to 86% for Cd and their removal average was 43%. High concentration of Pb in both raw and treated water was remarkable. It was fo...
