摘　　要：采用离心法、水热反应法和回流法制备出ZnO-Zn Al水滑石(ZZA),考察了ZZA吸附城市污水处理厂尾水中磷酸盐的最佳p H、最佳投加量;并用钠基改性膨润土、煤渣、沸石与ZZA进行对比吸附实验,结果表明:ZZA吸附除磷最佳投加量为50 mg/L,此时的磷酸盐去除率可以达到70%,处理效果较佳。ZZA吸附城市污水处理厂尾水中磷的效果与钠基改性膨润土、煤渣、沸石相比,其吸附效果最佳。The centrifugal method,hydrothermal reaction method and reflux method were used to prepare ZnO-ZnAl hydrotalcite（ ZZA） for the investigation of the ZZA adsorption of the phosphate in the tail water from the urban sewage treatment plant and the best condition of p H,the optimal dosage were identified; and the absorptive effects of sodium base modified bentonite,coal cinder,zeolite and ZZA were compared. The results show that： the optimal dosage of ZZA for phosphorus removal was 50 mg/L,the removal rate of phosphate could reach 70%,and the treatment effect was good.ZZA had the best effect on adsorption of phosphorus in the tail water compared with sodium base modified bentonite,coal cinder and zeolite.
