摘　　要：利用FeSO4在微波辐照条件下制备改性膨润土,利用其对含磷废水进行处理,考察了微波辐照功率、辐照时间、FeSO4添加量等对制备条件的影响,实验结果表明,当微波辐照功率480W、微波辐照时间8min,FeSO4添加量为50mg时,改性膨润土的制备条件较好。除磷实验表明,当溶液pH值为6、接触时间15min、投加量5.0g时,改性膨润土对50mg/L含磷废水的去除率达到98%。By means of microwave radiation,FeSO4 modifi ed Linan bentonite adsorbent was prepared.The adsorbent behaviour of phosphorus in wastewater was discussed.Effects of microwave power,microwave time and FeSO4 dosage on preparation conditions were investigated.The results showed that under the condition of microwave power 480W,microwave time 8min and FeSO4 dosage 50mg were better conditions.The experiment showed that pH value 6.0,reaction time 15min and with the modifi ed bentonite dosage 5.0g,the removal rate of phosphorus wastewater is 98% when the concentration was 50mg/L.
