淮河以北部分地区机井地下水氟的检测与水化学特征

Comment about the Water Chemistry Characteristic of Groundwater Fluorine in the North of Huaihe Region

淮河以北部分地区地氟病重、中、轻、非病区氟在地下水富集的水化学特征是:氟多富集在重碳酸钠(苏打)型、pH值偏高(8.00左右)、碱化程度相对较强的低矿化度(<1000mg/L)水中,并阐述了开成机理。

The North of Huaihe region ground fluorine disease is heavy,medium,light,the non- disease area fluorine is rich and gather in the groundwater of water chemistry characteristic ：The Fluorine is much rich to gather in the heavy carbonic acid sodium type,pH value higherly （8.00 or so）,the alkali turn the degree opposite and stronger and low mineral turn degree（ 〈1000 mg/L） water, and elaborated formation mechanism.
