中文摘要: 摘 要：目的：对上海市浦东新区滨江步道公共区域直饮水和市政管网自来水(以下简称市政水)的水质现状进行全面 评估，为水处理工艺和直饮水设备优化提供科学依据。方法：选择浦东新区滨江步道的23台净化饮用水处理设备为研究对 象，于2024年6—7月对23个直饮水点及其对应的市政水开展两轮采样，共采集水样115份(市政水样46份，直饮水样69 份)。结果：直饮水样菌落总数、浑浊度、pH 值、总氯、铝、三氯甲烷等指标数值均低于市政水样，差异均有统计学意义 (Z 值分别为-2.595、-4.850、-3.304、-10.123、-1.982、-9.794,P<0.05); 直饮水样锌含量高于市政水样，差异有统计 学意义 (Z=-2.135,P<0.05) 。 市政水样、直饮水样的铝含量均和pH 值呈正相关(P<0.05) 。46 份市政水样检测合格率 为100.00%(46/46),高于直饮水样[97.1%(67/69)],差异无统计学意义 (P>0.05) 。 直饮水样不合格指标分别为菌落总 数和锌指标。结论：直饮水管理单位需加强日常维护管理，对于用水量较少、区域偏僻的直饮水设备可以通过加强维护频次、 定时放水冲刷管网和取水口等措施改善水质状况。
Abstract:Abstract: OBJECTIVE To evaluate the water quality of public direct drinking water(DDW)and municipal water in a riverside pedestrian area of Pudong New District of Shanghai sourced.Through data collection and analysis,aim to provide scientific evidence for optimizing water treatment processes and DDW equipment.METHODS A total of 23 purified drinking water treatment devices along the riverside walkway were selected as study subjects.In June and July 2024,two rounds of sampling were conducted at 23 DDW points and their coresponding municipal water sources,yielding 115 samples(46 municipal water samples and 69DDW samples). RESULTS Drinking water samples exhibited significantly lower levels of total bacterial count,turbidity,pH,total chlorine,aluminum,and trichloromethane compared to municipal water samples(Z=2.595,-4.850,-3.304,-10.123,-1.982,-9.794;P<0.05).Zine content in drinking water samples was statistically higher than in municipal water samples(Z=2.135,P<0.05).Both municipal and drinking water samples showed positive correlations between aluminum content and pH levels(P<0.05).A1146 municipal water samples passed quality testing(100.00%compliance rate,46/46),significantly higher than drinking water samples (97.1%compliance rate,67169),though the difference was not statistically significant(P>0.05).The main non-compliant indicators in drinking water samples were total bacterial count and zinc content.CONCLUSION Direct drinking water management units need to strengthen daily maintenance and management. For areas with less water consumption and remote areas,the water quality can be improved by strengthening the frequency of maintenance, flushing the pipe network and water intake regularly.
