生活饮用水理化指标中浊度、色与铁离子、锰离子的相互关系以及“三氮”的相互关系的分析已有不少报道。但有关ｐＨ值、氯化物、阴离子合成洗涤剂(ＡＢＳ)之间的关系以及与氨氮浓度的关系则报道甚少。为了解其关系 ,从而保证居民安全用水 ,促进居民健康 ,我们于 1 995年～ 1 99 Physical and chemical indicators of drinking water turbidity, color and iron ions, manganese ions and the relationship between the “three nitrogen” analysis of the relationship has been reported. However, the relationship between pH, chloride, anionic synthetic detergent (ABS) and its relationship with ammonia concentration is poorly understood. In order to understand their relationship so as to ensure the safe use of water by residents and to promote the health of residents, we from 1995 to 1999
