以地下水为水源的饮用水分层结垢分析

Drinking Water From Underground WaterLayer Scaling Analysis

很多地区采用地下水为饮水水源,饮用水在加热过程中,出现分层结垢现象,下层为白色沉淀,上层为白色晶体片状漂浮物,对饮水安全形成了一定的负面影响。通过实验分析,确定了水中所含离子的性质及含量,得出了水中存在的形成垢质的主要成分为钙镁硬度和碳酸盐碱度。在结垢离子含量达标的情况下,对分层结垢机理给予了科学合理的解释,消除了饮水安全顾虑,为水处理设施改造和建设提供科学依据。

Many areas use the ground water as the potable water source,the tap water in the heating process presents the lamination scaling phenomenon,the lower level is white precipitates,the upper formation is the white crystal shape floating matter,it has formed certain negative influence safely to the potable water.In this paper,ions and their properties in the water were analyzed by experiments.The results show that formation of the scale principal constituent depends on calcium-magnesium hardness and carbonate alkalinity in the water.At last,the science reasonable explanation to the lamination scaling mechanism was given,which can eliminate worry about drinking water safety and provide a scientific basis for transformation and construction of the water treatment facility.
