摘　　要：采用人造沸石和4A沸石对含磷50mg·L-1模拟废水进行吸附实验,研究了沸石用量、含磷浓度、吸附时间、反应温度和pH值对两种沸石吸附性能的影响。结果表明,室温,pH=2～3,P2.5mg/g(沸石),吸附100min的条件下,两种沸石对磷的去除率均在90%以上,4A沸石对磷的吸附效果优于人造沸石。Experiments are conducted on the phosphate absorbability of artificial zeolite and 4A zeolite in simulated wastewater with phosphate concentration of 50 mg·L-1.The effects of the amount of zeolites applied,phosphate concentration,absorbing time,and reaction temperature on the phosphate absorbability of these two kind zeolites are studied.The results show that the phosphate removal efficiency of these two kind zeolites exceeds 90% at the room temperature,pH volume from two to three,P2.5 mg/g(zeolite),absorption time 100 minutes,respectively.The phosphate absorbability of 4A zeolite is better than the artificial zeolite.
