摘　　要：根据碳酸电离分布理论探讨了绵阳城市管网水的水质类型,推导出了温度影响下的饱和pH的计算公式,并采用Langelier饱和指数和Ryznar稳定指数这两个指数分析了绵阳城市供水系统的水质化学稳定性,对优化供水生产、管网调度和调整水处理工艺具有重要的指导意义。The water quality model was discussed according to the ionization distribution theory of carbonic acid. The calculated formulas of saturation pH value influenced by temperature were derived. Langelier saturation index and Ryznar stable index were applied to analyze the water chemical stability in urban water distribution system in Mianyang, which had an important significance in production optimization, networks dispatching and water treatment adjustment.
