天然水开放与封闭系统中CaCO_3溶解或沉淀的水化学后果比较

A COMPARISON BETWEEN THE EFFECTS OF DISSOLUTION OR PRECIPITATION OF CaCO3 ON THE PROPERTIES AND THE COMPOSIT- IONS OF WATER IN THE OPEN AND CLOSED SYSTEMS UNDER NATURAL CONDITIONS

本文以4个水样的水化学分析结果为例,对开放系统与封闭系统中CaCO_3溶解或沉淀所造成的水化学后果进行了计算和比较;在此基础上,还对天然条件下水中CaCO_3溶解或沉淀可能造成的水化学结果进行了讨论.

Taking the chemical analysis results of the 4 water samples as the examples, the authors calculated and compared the changes of pH values,the saturation indices of calcite,and the equilibrium distribution of species caused by the dissolution or the precipitation of CaCO3 under the conditions of the open and closed systems in this paper . On the basis of the above comparison, the authors discussed the dissolution and precipitation of CaCo3 under natural conditions.
