驻岛某部自备水源水质监测分析

Monitoring and analysis of self-supplied water source in a troop in an island

目的调查驻岛某部自备水源的水质现状,为改善海岛部队水源水质提供科学依据。方法按照GB 5750—2006《生活饮用水标准检验方法》进行水样的采集、检测,依据GB 5749—2006《生活饮用水卫生标准》和GB 19298—2014《包装饮用水卫生标准》对检测结果进行判定和评价。结果自备井水的总合格率为25.0%,其中毒理学指标、一般化学指标、感官性状指标和微生物指标的合格率分别为90.9%、53.8%、0.00%、0.00%,超标最严重的是菌落总数、总大肠菌群、色度。净化水的总合格率为57.14%,其中感官性状指标、一般化学指标、微生物指标的合格率分别为100.0%、90.0%、50.0%,超标项目分别是菌落总数、电导率和大肠菌群。结论驻岛某部自备水源的卫生现状较差,水质合格率不高。

Objective To detect the drinking -water quality in an island, so as to provide scientific basis for improving the quality of source waters. Methods The water samples were collected and detected according to GB 5750--2006 Standard Test Methods for Drinking Water and the results were evaluated according to GB 5749--2006 Drinking Water Sanitary Standard and GB 19298--2014 Hygienic Standard for Packaged Drinking Water. Results The qualified rates of the water samples were 25.0%, and the qualified rates for toxicology indexes, general chemical indexes, senses and microorganisms indexes were 90.9%, 53.8%, 0.00% and 0.00%, respectively. For microorganisms indexes, the worst items were total plate count, coli- form bacteria and chromacity. The qualified rate of purified water was 57.14%, and the rates for senses, general chemical inde- xes and microorganisms were 100.0%, 90.0%, 50.0%, respectively. The excessive indexes include total plate count, coli- form bacteria and specific conductivity. Conclusion The water qualities were poor and measures should be taken to improve the quality of source waters.
