文章以中南地区40多个供水厂原水为主要研究对象，针对供水厂原水水质化学稳定性及其控制方法，进行了以下研究：（1）中南地区供水系统原水水质稳定性现状调查；（2）腐蚀产物的物理化学特性；（3）原水水质化学稳定性的变化规律；（4）供水系统水质稳定性的控制方法。为了全面、客观的评价水质化学稳定性问题，本文采用稳定指数和饱和指数配合使用来综合评价水质化学稳定性，并综合考虑pH值、钙离子含量、侵蚀性二氧化碳的影响，研究发现，饱和指数IL小于0.6、稳定指数IR大于8以及含高浓度侵蚀性二氧化碳会增加水的腐蚀倾向，可根据不同的作用机理选择相应的防护技术。

Taking the raw water of forty water plants in central and southern China as research object, this paper researched on the following subjects by focusing on raw water chemical stability and control technology ： 1 ） investigate the status of various types of raw water chemical stability ; 2 ） physical and chemical properties of corrosion products ; 3 ） variation rule of raw water chemical stability; 4）control approaches of raw water chemical stability. To evaluate the chemical stability of water comprehensively and objectively, this study combined Langelier＇s Saturation Index and Ryznar＇s Stability Index to evaluate water chemical stability, ph value and calcium ion density, carbon dioxide density. Results show that the water is strongly corrosive when Saturation Index is less than - 0. 6 and Stability Index is greater than 8. 0 or high - concentration carbon dioxide. Corresponding protective technology can be used according to all kinds of interaction mechanisms.
