淮北市生活饮用水水氟含量检测分析

Analysis of Contents of Fluorine in Drinking Water in Huaibei City

目的研究淮北市生活饮用水水氟含量,为改水降氟提供科学依据。方法抽样采集淮北市市辖3区所有行政村的生活饮用水,氟离子选择电极法测定氟含量。结果水氟超标率为21.65%;市辖3区水氟含量不均衡;深水井水氟超标率明显低于浅水井(2.93%<27.97%)。结论打深井是改水降氟的有效途径。

Objective To perfect the background data of fluorine contents in drinking water in Huaibei city and provide a scientific basis for the water - improving and defluoridation. Methods We collected the drinking water sanrples of all the administrative villages in Huaibei city and determined the contents of fluorine in water by fluoride selective electrode. Results The excess standard rate of water fluorine was 21.65%. The contents of fluorine in water were unbalanced in the administrative area of Huaibei city; the excess standard rates of water fluorine in deep water wens were significantly lower than those of shallow wells. Conclusion Drilling deep wells is a effective way to improve the water quality and reduce the fluoFine.
