水质氨氮、亚硝酸盐氮和硝酸盐氮(以下简称三氮)与细菌指标是分析水质清洁与污染程度的重要指标,长期以来,有关作者对三氮指标与细菌总数、大肠菌群之间的变化有无内在联系持不同看法,我们收集整理了自1989～1991年部分驻京部队丰水期水源水共135份水样进行观察、分析,现将结果简介如下。资料来源与收集方法统计分析资料共计135份,分别选自驻京三总部机关单位和下属基层部队的深井水源水,且水样未经过消毒处理。
Ammonia nitrogen, nitrite nitrogen and nitrate nitrogen (hereinafter referred to as the three nitrogen) and bacterial indicators of water quality is an important indicator of the degree of analysis of water quality and pollution, a long time, the author of the three nitrogen indicators with the total number of bacteria, coliform We have gathered and analyzed 135 water samples collected from the source water of some Beijing-based troops during the wet season from 1989 to 1991 for observation and analysis. The results are summarized as follows. A total of 135 data sources were collected from the statistical analysis of data collection methods, which were selected from deep well water sources of units and subordinate grass-roots units in Beijing headquarters and water samples were not disinfected.
