安徽省淮北市欧山泉水水质分析及评价

Evalution of water quality for Oushan spring in Huaibei,Anhui Province

为了了解安徽省淮北市欧山泉水水质卫生质量状况,探究其是否可以作为居民生活饮用水,按GB/T 5750—2006《生活饮用水标准检验方法》和GB/T 8538—2008《饮用天然矿泉水检验方法》对淮北欧山泉水进行检测.结果表明,淮北欧山泉水无味、无色,浑浊度约为2.7NTU,常温下,无悬浮物和沉淀.泉水水样的pH值为8.31,为碱性水.砷、硒均小于0.1μg/L,远低于饮用天然矿泉水的界限指标.溶解性总固体(TDS)为175mg/L,属Ⅰ类水范围.氨氮、硝酸盐氮、钾、钠、镁、钙、六价铬的含量均符合饮用天然矿泉水和生活饮用水的要求.总体上说,所检测的欧山泉水指标均达到生活饮用水的要求.

In order to understand the quality of the Oushan spring water,and explore whether it can be used as drinking water,according to Standard Examination Methods for Drinking Water(GB/T 5750—2006)and Methods for Examination of Drinking Natural Mineral Spring(GB/T 8538—2008),the Oushan spring was detected by us.The results show that the pure Oushan spring is odorless,colorless,and with turbidity about 2.7 NTU.Oushan spring is weak alkaline water with pH value 8.31.Meanwhile,arsenic and selenium contents are all less than 0.1μg/L,below the limits of drinking natural mineral water.Total soluble solids(TDS)is 175mg/L,superior toⅠwater quality standard.The contents of ammonia nitrogen,nitrate nitrogen,potassium,sodium,magnesium,calcium and hexavalent chromium are in line with the requirements of drinking natural mineral water and drinking water.In a word,the detected indexes of Oushan spring conform to the requirements of drinking water.
