中文摘要：

通过微观分析方法,在鄂尔多斯盆地白垩系钻孔岩样中发现方沸石类矿物。对该方沸石岩进行提纯和改性,制成多孔方沸石球处理含氟水。对于100 mL起始浓度5.00 mg/L的含氟水,多孔方沸石球较佳的水处理试验条件为：用量3.0 g,搅拌后静置48 h,球直径3 mm。多孔方沸石球对氟离子的吸附符合Lang-muir吸附等温式,吸附速度符合斑厄姆公式。用过的方沸石球经再生处理后活性基本恢复,多次再生后方沸石球除氟效果有所下降。

英文摘要：

Analcite minerals were found from sedimentary rocks of cretaceous system in Ordos basin using micro-analysis. Porous analcite balls were prepared by analcite rocks after purifying and modification. Then porous analcite balls were used in treatment of fluorine water. Treating 100 mL solution containing 5. 00 mol/L fluorine, good result was obtained when the experimental condition of analcite balls was ： dosage 3. 0 grams, stilling 48 hours after stirring, diameter 3 millimeters. The absorption equation of porous analcite balls is in conformity with the Langmuir equation. The rate equation of porous analcite balls is in conformity with the Banerm equation. Consumed analcite balls almost recovered activity after regeneration. The efficiency of fluoride removal is slightly lower when porous analcite balls have been regenerated for many times.
