摘要
在一定条件下氢氧化铝废渣活化处理，用于处理５０ｍｇ／Ｌ的含氟废水，投加量为２‰，ｐＨ值为６～１１，去氟率达９６％。吸附平衡浓度与吸附量关系符合Ｌａｎｇｍｕｉｒ等温式，求出２０．０℃、２５．０℃、３０．０℃时的饱和吸附量和吸附系数。其吸附速度符合鲛岛吸附动力学方程式。
Aluminium hydroxide waste is preactivted at proper tempreature before it is used to treat wastewater containing fluorine about 50G*4mg/L.Fluorine removal reaches 96% when the addition is 2 at a pH value range from 6 to 11.The relationship between equilibrium concentration and adsorption amount is fit for Langmuir isothermal adsorption and the adsorption rate comforms to Jiaodao dynamic equation.
