吉布提等城市及码头给水卫生质量的调查分析

目的:了解护航编队停靠码头及城市供水水质情况,为舰艇停靠补给提供科学依据。方法:在亚丁、塞拉莱和吉布提的城市和对应港口,调查了59个供水点的基本卫生情况,抽检85样品,进行电导率、pH值、肉眼可见物、重金属、阴离子和菌落总数等23个项目分析,并进行比较分析。结果:结果显示,塞拉莱码头地下水,吉布提和亚丁地下水和城市供水的电导率、CL-、SO42-和总硬度指标远超出我国和WHO标准限值。只有净化水和塞拉莱城市供水的各项指标均符合《生活饮用水卫生标准》(GB/T 5749-2006)。结论:仅有净化水和塞拉莱城市供水可用于船舶生活饮用水补给。

The sanitary quality survey of groundwater and purified water in Djibouti,Salalah and Aden and their ports

Objective:To understand and master the condition of drinking water quality of cities and ports that Chinese navy escort ships berthed,in order to provide scientific basis for escort ships drinking water supply.Methods:Main condition of 59 water points in three cities(Djibouti,Aden and Salalah)and their ports was surveyed.There were 85 samples collected from these cities and ports.Various physiochemical parameters including pH,temperature,electrical conductivity,naked eye visible residue,color,odor and flavor,total hardness,heavy metal(Fe,Pb,Cd,Cr),anions(F-,Cl-,SO42-,NO3-)and coli form group bacteria were measured from the groundwater and purified water samples.Results:The results showed that conductivity,chloride,sulfate,nitrate and total hardness of ground water in Salalah port,Djibouti port and suburban area of Aden city were above the acceptable levels in the Chinese standards for drinking water quality(2006)and WHO(2004).By measuring drinking water samples from Salalah city and purified water samples,we found that these results were in agreement with the range of values of Chinese Standards for drinking water quality(2006).Conclusion:Only purified water and drinking water from Salalah city were suitable to supply escort ship as drinking water.
