2013-2014年厦门市港口船舶二次供水水质现状研究

Current status of hygienic quality of secondary water supply in ships in Xiamen Port,2013-2014

目的了解2013-2014年厦门港区船舶二次供水的卫生状况,为改善船舶二次供水卫生状况和进行卫生监督提供理论依据。方法采集2013-2014年厦门港区船舶二次供水的水样50份,根据GB5749-2006《生活饮用水卫生标准》进行检测。结果 2013-2014年总共监测50份样本,其中指标全部合格样本数19份,总合格率38%,2年的合格率分别为36%、40%。菌落总数合格率50%、总大肠菌群数合格率84%、氟化物合格率98%、锌合格率94%、总硬度98%、浑浊度合格率96%、铁合格率96%。结论 2013-2014年厦门港区船舶二次供水总合格率较低,主要是细菌学指标超标,所以应采取有效措施,改善水质,加大对供水点和船舶二次供水的监督力度,保证船上人员的身体健康。

Objective To investigate the hygienic quality of secondary water supply in ships in Xiamen Port during 2013-2014 so as to provide a theoretical basis for improving the hygiene status of secondary water supply of ships and conducting hygiene supervision. Methods Fifty water samples were collected from secondary supplied water in ships in Xiamen Port during 2013-2014,and then detected according to Sanitary Standard for Drinking Water（ GB 5749- 2006）. Results A total of 50 water samples were detected from 2013 to 2014,of which 19 were qualified,with the qualified rate of 38%. The qualified rates in 2013 and 2014 were 36% and 40%,respectively. The qualified rates of total bacterial count,total coliform bacteria,fluoride,zinc,total hardness,turbidity and iron were 50%,84%,98%,94%,98%,96% and 96%,respectively. Conclusions The total qualified rate of secondary supplied water in ships in Xiamen Port during 2013- 2014 is low,and the main problem is the exorbitant bacteriological indicators. Therefore,we should take effective measures to improve water quality,enhance the supervision on water supply points and secondary water supply in ships so as to ensure the health of persons on board.
