摘　　要：目前,我国的矿物废渣还没得到充分再利用,利用钢渣为主要原料制备处理含磷废水的吸磷剂,探索了适宜制备方案并对其进行了应用研究,确定了适宜的工艺条件。试验结果表明：吸磷剂的适宜制备条件为粘土、水和钢渣按质量比1.0∶1.0∶1.0混合并加入FeSO4,FeSO4加入量为[m（FeSO4）/m（粘土、水和钢渣）]为0.07,挤压成粒,在500℃下灼烧5 min。利用吸磷剂处理质量浓度为50 mg/L的磷酸盐废水,适宜工艺条件为投加量为0.8 g/L,振荡时间为1.5 h,pH值在7~8,磷去除率（以磷元素为基准）为95%左右。Because of insufficient usage of mineral waste residue, the preparation of sorbent of phosphor with slag was brought forward to treat wastewater. The experimental results indicated the suitable preparation conditions were： caly, water and slag were mixed together with mass ratio of 1.0 ： 1.0 ： 1.0, and FeSO4 [ m （ FeSO4 ） / m （clay, water and slag） = 0. 07 ] was added, baked 5 miutes at 500 ℃. It was used to treat the wastewater with mass concentration of 50 mg/L, the addition of this sorent was 0.8 g/L, vibration time was 1.5 h and at pH 7--8, the removal rate of phosphor were about 95 %.
