摘要
目的:了解广州市住宿场所二次供水的卫生状况,为加强卫生管理提供科学依据和合理建议。方法:2009年-2011年对广州市部分住宿场所的二次供水水样进行采集、检测和分析。结果:2009年-2011年共检测二次供水水样128份,51份合格,总合格率为39.84%。2011年合格率(83.33%)明显高于前两年合格率(分别为25.00%、36.36%),差异有统计学意义(P<0.05)。主要不合格指标为细菌总数、耗氧量(合格率分别为53.91%、72.66%)。2009年、2010年住宿场所二次供水合格率明显低于城市管网末梢水合格率(P<0.05),2011年住宿场所二次供水和城市管网末梢水合格率差异无统计学意义(P>0.05)。结论:广州市住宿场所二次供水质量近年有所提高,但仍不够理想,需进一步加强规范建设、卫生管理和监督监测。
Objective ： To understand the sanitary status of secondary water supply system in hotels in Guangzhou, so as to provide scientific basis and reasonable suggestion for health management. Methods：The water samples of secondary water supply system in hotels in Guangzhou were selected, tested and analyzed from 2009 to 2011. Results： One hundred and twenty - eight water samples were tested, with 51 samples qualified. The qualified rate was 39.84%. The qualified rate in 2011 was significantly higher than that in 2009 and 2010（ P 〈 0. 05 ）. The major un- qualified items were total bacterial count and oxygen consumption, with the qualified rates of 53.91% and 72.66% respectively. The qualified rates of secondary water supply system in hotels were significantly lower than those of terminal water supply in city in 2009 and 2010（ P 〈 0. 05 ）, while there was no significant difference between the qualified rates of secondary water supply system in hotels and that of terminal water supply in city in 2011 （ P 〉 0.05 ）. Conclusion： The sanitary status of secondary water supply system in hotels in Guangzhou was improved in recently several years. But there were still many hygienic problems in secondary water supply system. Standard construction, health management, supervision and inspection of secondary water supply system should be strengthened.
