齐鲁师范学院新校区水质的分析

Analysis of the Water Quality in the New Campus of Qilu Normal University

以齐鲁师范学院章丘新校区生活饮用水(自来水、凉开水)和中水为研究对象,以去离子水为对比样品,分别采用分光光度法、玻璃电极法和EDTA滴定法测定了水样的浊度、pH值和总硬度。实验结果表明,新校区的自来水在这三个方面均符合国家规定的饮用水水质标准,中水符合国家规定的建筑中水水质标准。中水的浊度明显高于自来水。自来水和中水的pH值没有明显差别。加热煮沸后,自来水的总硬度明显降低,pH值略有升高。

The quality of the drinking water and reclaimed water in the new campus of Qilu Normal University was studied. De - ionized water was used as the control sample. The turbidity, pH and total hardness of the water samples were analyzed by Spectrophotometer method, glass electrode method and titration method respectively. The results show that the above three aspects of the drinking water and reclaimed water in the new campus all met the required quality standards of PRC. The turbidity of the reclaimed water was significantly higher than that of the drinking water. The pH of the drinking water is not obviously different from that of the reclaimed water. After the water was boiled, the drinking water＇s total hardness decreased greatly and its pH increased slightly.
