Abstract：Objective By analyzing inspection data of secondary water quality in some troops stationed in Beijing from 2012 to 2014, to understand sanitation of secondary water supply in troops in Beijing, so as to provide a scientific basis for strengthening the integrated management of secondary water supply of the forces, and to improve water quality.Methods The secondary water(218 samples) and municipal water(180 samples) of the troops stationed in Beijing were collected and detected according to "Drinking Water Standard Test Method" (GB / T 5750-2006), and determined exceedances of the indicators according to "Drinking Water Health Standards" (GB 5749- 2006) .Results The total qualified rate of all the secondary water samples tested was 82.6%. The qualified rates of total coliforms (92.3%), nitrate nitrogen (93.6%) and total bacteria (94.9%) were relative low. The qualified rates of secondary water were 61.3%, 88.7%, and 84.5% in 2012, 2013, and 2014 respectively, which in 2012 was significantly lower than those in 2013 and 2014 (P﹤0.05). There was no statistical significance between secondary water and municipal water(P >0.05). There was statistical significance between wet and dry seasons about the qualified rate of secondary water(P﹤0.05).Conclusion Water quality of secondary water is generally good in recent two years in the troops stationed in Beijing, but some measures should be taken to be further improve water quality of secondary water .
