摘要 介绍化学稳定性的定义及常用的判别指标。通过收集数据对于某市供水管网水质化学稳定性进行计算分析,得到该市化学稳定性评价指数,其中Langelier饱和指数位于0~0.5区间,均值0.2;Ryznar稳定指数位于7~7.5区间,均值7.44;AI侵蚀指数位于12~13区间,均值12.26;LR拉森比率位于1~2区间,均值1.69。探讨利用水质调节技术和改进管网、管材手段控制水质化学稳定性。 This article introduces the definition of chemical stability and commonly used criteria.By collecting data to calculate and analyze the chemical stability of the water quality of a city’s water supply network,the city’s chemical stability evaluation index was obtained.The Langelier saturation index was in the range of 0~0.5,with an average value of 0.2;the Ryznar stability index was in the range of 7~7.5,with an average of 7.44;the AI erosion index is in the range of 12~13,with an average of 12.26;the LR Larson ratio is in the range of 1~2,with an average of 1.69.Explore the use of water quality regulation technology and the improvement of pipe networks and pipe materials to control the chemical stability of water quality.
