【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首次发现方沸石类矿物。就地取材,对方沸石岩进行提纯和改性,制成多孔方沸石球,用于含氟水的处理,取得了明显的效果。对于100 mL起始浓度3 mg/L的含氟水,方沸石球较佳的水处理工艺条件为:用量1.5 g,搅拌后静置48 h,直径3 mm。对于起始浓度3 mg/L的含氟水,方沸石球一次水处理后氟离子浓度就低于国家标准值。对于起始浓度3~10 mg/L的含氟水,经方沸石球几次水处理后氟离子浓度也低于国家标准值。方沸石球对氟离子吸附等温线符合Langmuir吸附等温式,为:qe=(0.243ce)/(1+0.433ce);吸附速度符合斑厄姆公式,为:(dq)/(dt)=4.482×10-3(qe-q)/t0.176。用过的方沸石球再生处理后活性基本恢复,多次再生后除氟效果有所下降。
【英文摘要】 Analcite minerals were first found from sedimentary rocks of cretaceous system in the Ordos basin using micro-analysis.Porous analcite balls were prepared from the analcite rocks after purifying and modification and then were used to remove fluorine.The fluorine removal effect is very obvious.Treatment 100 mL solution containing 3 mg/L fluorine,better technological condition of analcite balls has been obtained.The dosage of analcite balls is 1.5 grams.The stilling time is 48 hours after stirring.The diamete...
