摘　　要：以高氟水为饮水源造成了饮水型地氟病。本文以模拟含氟水为处理对象,以改性煤矸石作吸附剂进行除氟研究。考察了溶液pH值、改性方法、吸附时间、氟离子初始浓度等影响因素。当氟离子初始质量浓度为5.0 mg/L、吸附剂用量4 g/L、反应30 min、pH值为5时,涂铝煤矸石吸附处理后出水含氟低于我国《生活饮用水卫生标准》(GB 5749-2006)中规定饮用水中氟化物的最高容许质量浓度1.0 mg/L。动力学研究表明,涂铝煤矸石对氟的吸附动力学行为符合二级速率方程。Excessive fluoride in drinking water can lead to Endemic Fluorosis.Using simulation water containing fluoride as treated object,modified coal gangue as adsorbent to treat the water was studied.Some influence factors such as pH of solution,modified ways,adsorption time,and initial fluoride concentration were researched.Experimental results showed that when initial fluoride concentration 5.0 mg/L,dosage of adsorbent 4 g/L,contact time 30 min and pH value 5,the water containing fluoride was lower than 1.0 mg/L after treatment by modified coal gangue by aluminum hydroxide,which equal to the high permissible concentration of“Standards for Drinking Water Quality”.Kinetics study indicated the adsorption process accorded with second-class-rate equations.
