榆林市西沙生活饮用水水质综合评价及分析

Comprehensive Evaluation and Analysis of Drinking Water Quality in Xisha,Yulin

基于榆林学院校区2014年6月份水质监测报告中的数据,采取模糊综合评价法对该区域生活饮用水的8个水质指标(氟化物、总硬度等)进行评价,得出:校区北围墙和东锅炉房两处水源的水质属于Ⅰ类,水质良好。然水中氟化物含量较低,低于世界卫生组织规定的最低浓度,应在日常饮食中多摄取含氟的食物或使用含氟牙膏,以降低患龋齿风险。两处水源的水中总硬度含量虽远低于生活饮用水卫生标准,但仍属于中等硬度范围,为暂时硬度含量高,应采取软化措施,降低硬度。

Fuzzy comprehensive evaluation method was used to evaluate the life drinking water 8 indicators （Fluoride, total hardness, etc） based on the water quality monitoring report data of Yulin University campus in ]une 2014. It was concluded that the source water quality of north wall and the eastern boiler room were good, belonged to the first class index. However, the fluoride content was lower than the minimum concentration of World Health Organization standard, daily intake of food containing fluorine or using fluoride toothpaste should be increased, in order to reduce the risk of dental caries. Meanwhile, the content of total hardness was far lower than the health standard for drinking water, belonged to the scope of medium hardness, which was mainly because the temporary content was high. So relevant water softening measures to reduce the hardness of life drinking water should be adopted.
