目的全面了解驻京总直部队近5年来饮用水水质状况及变化规律,为驻守大中城市部队的饮用水卫生监督及指导用水安全提供科学依据。方法回顾分析2011-2015年间驻京总直部队水质监测结果。市政自来水及自备井水按照《生活饮用水标准检验方法》(GB/T 5750-2006)进行水样采集和检测,按照《生活饮用水卫生标准》(GB 5749-2006)进行水质评价;桶装纯净水按照《瓶(桶)装饮用纯净水卫生标准》(GB 17324-2003)进行检测和评价。结果 2011-2015年间驻京总直部队饮用水总体合格率为69.4%,合格率比较:市政自来水>自备井水>桶装纯净水。市政自来水及自备井水的主要超标项目为微生物指标及感官指标,毒理学超标项目主要集中在硝酸盐氮;桶装纯净水电导率不达标问题比较突出;近2年来市政自来水的平均总硬度比前3年降低约30%。结论驻京总直部队饮用水卫生学问题集中,尤其是微生物指标超标可能造成水媒性疾病的暴发或传播。应加强对自备井水水源及二次供水储输水设施的管理与防护,规范清洗及消毒措施,加强对部队桶装纯净水生产过程的监督管理,加大水质监测力度,确保官兵饮用水安全。
Objective To obtain a comprehensive understanding of drinking water quality and regulation in the past 5 years in Beijing’s total direct army unit and provide a scientific basis for drinking water sanitation supervision and guidance on water safety in large and medium-sized urban units. Methods A retrospective analysis of the water quality monitoring results of the Beijing Zhoushan General Directorate between 2011 and 2015 was conducted. Municipal tap water and self-prepared well water shall be subjected to water sample collection and testing in accordance with the Standard Test Method for Domestic Drinking Water (GB / T 5750-2006), and water quality shall be assessed in accordance with the Standard for Drinking-water Quality (GB 5749-2006) Packed with pure water in accordance with the “bottle (bucket) purified drinking water health standards” (GB 17324-2003) for testing and evaluation. Results The overall pass rate of drinking water of General Directorate troops stationed in Beijing from 2011 to 2015 was 69.4%. The pass rates were compared with municipal tap water> self-made well water> pure bottled water. Municipal tap water and self-prepared well water are the main indicators of excessive microbial indicators and sensory indicators, toxicology exceeded the project mainly concentrated in nitrate nitrogen; barreled pure water conductivity of non-compliance problems more prominent; municipal tap water over the past two years, the average total hardness About 30% lower than the previous three years. Conclusions The problem of drinking water hygiene in the PLA General Staff Directorate in Beijing is concentrated. In particular, excessive microbial indicators may cause outbreaks or spread of waterborne diseases. The management and protection of self-provided well water sources and secondary water supply and storage facilities should be strengthened, measures for cleaning and disinfection should be standardized, the supervision and management over the bottled pure water production process of the armed forces should be stepped up, and the monitoring of water quality should be stepped up to ensure that officers and men of drinking water Safety.
