厦门港区2014-2015年国内船舶二次供水卫生状况研究

Study on sanitary conditions of secondary water supply on domestic ships in Xiamen Port from 2014-2015

目的了解厦门港区国内船舶二次供水水质现况,为卫生监督执法提供科学依据。方法对厦门港区2014—2015年国内船舶二次供水基本卫生状况进行现场调查和采样检测,以GB 5749-2006《生活饮用水卫生标准》进行检测结果评价,并对结果进行统计分析。结果 2014—2015年厦门港区国内船舶二次供水水质合格率分别为52.9%、10.0%,合格率差异有统计学意义(P<0.05),总体合格率仅为37.0%,其中菌落总数、总大肠菌群和浑浊度总体合格率依次为48.2%,77.8%,88.9%。结论 2014—2015年厦门港区国内船舶二次供水卫生状况总体合格率低,今后应加大对供水点和船舶二次供水的卫生监督力度,确保二次供水水质卫生。

[Objective]To understand the present sanitary quality of secondary water supply on domestic ships in Xiamen Port,provide a scientific basis for health inspection and quarantine enforcement.[Methods]The present sanitary quality of secondary water supply on domestic ships in Xiamen Port was surveyed by field investigation,sampling and detection from 2014 to 2015.The results were evaluated by the Drinking water sanitary standard（GB 5749-2006） and were statistically analyzed.[Results]The qualified rate of secondary water supply on domestic ships in Xiamen Port was 52.9% and 10.0% respectively from 2014-2015,and the difference was statistically significant（P〈0.05）.The total qualified rate was only 37.0%,while the total qualified rate of total bacteria counts,total coliform group and turbidity was 48.2%,77.8% and 88.9%,respectively.[Conclusion]The total qualified rate in sanitary quality of secondary water supply on domestic ships in Xiamen Port is relatively low from 2014-2015.In the future,it is necessary to strengthen the health supervision on water supply points and secondary water supply on ships to ensure the sanitary quality of secondary water supply.
