摘　　要：目的了解市区内二次供水设施状况和水质卫生现况,为政府有针对性地采取措施保障饮用水卫生安全提供科学依据。方法对辽宁省锦州市市辖区267家二次供水单位进行卫生监督检查,并对末梢水进行快速检测,分析影响水质的危险因素。结果 267家二次供水单位中水质合格单位229家,水质合格率为85.8%;1998年之前建设的二次供水设施水质合格率(79.1%)明显低于1998年之后建设的二次供水设施水质合格率(94.1%)(χ2=12.262,P <0.05),多因素logistic回归分析结果显示,建设年代(OR=6.106)、泵房内墙壁或顶棚无防霉措施(OR=3.749)、管道锈迹严重(OR=23.014)、生活用水和消防共用一个贮水设备(OR=3.880)、未办理卫生许可证(OR=5.723)是二次供水水质的影响因素(P <0.05)。结论锦州市市辖区二次供水水质合格率还有待进一步提高;政府及供水单位应加大对二次供水设施的卫生监督及整改力度,消除影响二次供水水质的危险因素,排除隐患,保障百姓饮水卫生安全。Objective To examine hygienic status of secondary water supply facilities and water quality in urban regions and to provide evidences for implementing targeted measures to ensure drinking water safety. Methods During 2016, health supervision and inspection were conducted on 267 secondary water supply facilities under the administration of Jinzhou municipality, Liaoning province;tap water samples were also collected for rapid detections of hygiene indicators;then impact factors for water quality were analyzed. Results The tap water from 229 of the 267 secondary water supply facilities were qualified, with a qualification rate of 85.8%. The qualification rate of tap water supplied by the facilities constructed before1998 was significantly lower than that supplied by the facilities constructed after 1998(79.1% vs. 94.1%,χ~2 = 12.262;P <0.05). Multivariate logistic regression analysis revealed that main impact factors of tap water quality of a water supply facility included the year for the construction the facility(odds ratio [OR]= 6.106), without fungus-resistant treatment for wall or ceiling of pump room(OR = 3.749), severe rusting of water supply pipes(OR = 23.014), with a water storage tank for both drinking water and fire fighting(OR = 3.880), and without hygiene license for the facility(OR = 5.723)(P < 0.05 for all).Conclusion The qualified rate of drinking water supplied by secondary water supply facilities in urban districts of Jinzhou city needs to be improved and supervision and management on the facilities should be strengthened by governmental agencies to ensure drinking water safety.
