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 status of secondary water supply for domestic ships in Xiamen Port Area and provide a scientific basis for health supervision and law enforcement. Methods On-site survey and sample testing were conducted on the basic sanitary conditions of secondary water supply in Xiamen port from 2014 to 2015. The test results were evaluated based on the standard of drinking water GB 5749-2006, and the results were statistically analyzed. Results The passing rates of secondary water supply of domestic ships in Xiamen Port from 2014 to 2015 were 52.9% and 10.0%, respectively, with significant differences (P <0.05). The overall pass rate was only 37.0%. The total number of colonies, total Coliform bacteria and turbidity overall pass rates were 48.2%, 77.8%, 88.9%. Conclusion In 2014-2015, the overall pass rate of secondary water supply for domestic ships in Xiamen Port is low. Health supervision on water supply points and secondary water supply to ships should be strengthened in the future so as to ensure the quality of secondary water supply.
