摘　　要：选用甘肃某地产天然沸石 ,经活化后处理含磷废水。研究了沸石活化的最佳条件 ,活化沸石处理含磷废水的各种影响因素 ,并在此基础上 ,研究了活化沸石对实际废水的处理效果。研究结果表明 :活化沸石能有效去除生活污水中的磷化物 ,但对以聚磷化物为主的含磷废水处理效果不甚理想 ;最佳除磷条件是 :沸石粒径 0 .5～ 1.6 mm,废水 p H值 4～ 12 ,含磷浓度 30 mg/ L,滤速3m/A kind of natural zeolite from Gansu was selected and activated for treating phosphide containing wastewater.In this paper,the best conditions,for zeolite activating,and the parameters which can effect the result of treatment,were studied.On the basis of these results,some real wastewaters were treated by activated zeolite.The results show that activated zeolite can effectively remove phosphide from sewer water,but can not remove soluble polyphosphide.The best treating conditions are:the size of zeolite 0.5～1.6mm,pH4～12,phosphide concentration in wastewater 30mg/L,and filter speed 3m/h.
