中文摘要:

      本文作者系以工程实例中遇到的问题为研究起因,从理论到实践观察研究了不同水质中加入3‰Ca(OH)2产生的现象并分析了出现的现象的本质,经反复实验成功得出水质随添加Ca(OH)2量增大产生的性状变化和pH值变化。从上述研究中作者研究得到的结论:在常温下反渗透产品水不可能形成的3‰的Ca(OH)2水溶液,除非降低温度以增加Ca(OH)2的溶解度

英文摘要:

      Inspired by issues encountered in projects,the writer of this paper observed phenomenon where 3 per Ca(OH)2 is added in water of different ingredient and looked into the essence behind.After repeated experiments,the writer successfully achieved tables and histogram showing character and pH changes to water along with change to the volume of Ca(OH)2 added to the water.The writer gets the conclusion from the aforesaid study that no water of 0.3% Ca(OH)2 can be created from [reverse osmosis product water] at ordinary temperatures,unless the temperature is lowered to increase the solubility of Ca(OH)2.
