| 摘 要： | 定边平原高氟地下水的形成,受控于地质环境、气候、地貌和水化学条件等;成因可分为溶滤型、浓缩型和溶滤一浓缩型。其水平分布规律,受地貌、地质和水文地质条件的控制。防氟改水方法,要因地制宜,灵活多样,综合改水;应采取打井和打窖相结合,分散供水与集中供水相结合,引水与理化除氟相结合。

| Abstract: | The formation of underground water in the Dingbian plain is controlled by environmental geology, climate, landform and hydrochemical conditions.The genesis type of the high-fluoride water can be divided into three types:lixiviation,inspissation and lixiviation-inspissation. The geomorphic and hydrogeological conditions control the distributional law in horizontal of the high-fluoride water and the strata; the lithologic character control the vertical changes of the water. For purifying the fluoride of the water, three ways can be utilized: 1. conjunctive operation of openning wells and water-storing cellars; 2. water suply of dispersion and concetration;3.diversion and purifying the fluoride of the water by physical-chemical methods. |
