摘要
目的了解深圳市福田区酒店生活饮用水卫生状况,保障饮用水卫生安全,为酒店生活饮用水卫生管理提供依据。方法对16家星级酒店的生活饮用水卫生状况进行卫生学调查,对采集的管网末梢水、二次供水、过滤水检测结果进行统计,按照《生活饮用水卫生标准》(GB/T 5749-2006)进行分析评价。结果该区酒店生活饮用水的合格率为95.1%,其中管网末梢水的合格率为96.1%,二次供水的合格率为96.0%,过滤水的合格率为93.6%,三者合格率水平差异无统计学意义(χ2=0.372,P>0.05)。从毒理学方面来看,过滤水的卫生隐患大,特别是重金属铅指标和金属铝指标。结论酒店生活饮用水的合格率很高,但部分水质存在较大的卫生隐患。饮用水管理疏漏和设计不合理的水池及老化的管道系统是影响酒店饮用水水质的主要原因。应加强饮用水卫生管理,采取综合措施,保障饮用水卫生安全。
