我所从1981年开始,先后对所属6个部队驻地的饮用水源水质进行了较全面的调查。现就饮用水及水源水的污染情况、原因及洁治措施报告如下。水质污染的情况水质污染情况见表1。从表1可以看出,虽然水源水质的污染指标大部分在容许范围以内,但仍有相当数量的水受到污染,甚至是严重的污染。如自来水氨氮含量>0.02～0.5mg/L者占检查总数的24.5％;亚硝酸盐氮>0.002～0.05mg/L者占18.4％;硝酸
Since 1981, I have carried out a more comprehensive investigation of the quality of drinking water sources at the six military units to which I belong. Now on drinking water and water pollution, the reasons and cleanliness measures are as follows. The situation of water pollution Water pollution in Table 1. As can be seen from Table 1, although most of the water pollution indicators of water quality are within the allowable range, there is still a considerable amount of water that is polluted and even seriously polluted. Such as tap water ammonia nitrogen content> 0.02 ~ 0.5mg / L accounted for 24.5% of the total inspection; nitrite nitrogen> 0.002 ~ 0.05mg / L accounted for 18.4%; nitric acid
