| 摘 要： | 水质化学稳定性评价指数较多,其中碳酸钙沉淀势(CCPP)是一个能定量分析CaCO3溶解或沉淀的精确指数.从理论上推导了CCPP计算模型,并基于Matlab计算求解.模型计算结果与已有相关软件的计算结果相比,该理论模型的计算值更接近试验结果,可以用其代替试验值进行水质化学稳定性分析.

| Abstract: | Among many water chemical stability indexes,the calcium carbonate precipitation potential(CCPP) is the one that can quantitatively analyze the accurate dissolved or precipitated CaCO3.This paper deduced a calculation model of CCPP from theory,and offered a calculating solving by Matlab.Compared with other existing related softwares,the results of CCPP were closer to the experimental results than the results of other softwares,therefor it could be used to replace the experimental data for water quality chemical stability analysis. |
