膨润土对水中磷的吸附研究

Absorption study on bentonites to phosphorus of water

对水中磷在膨润土上的吸附行为进行实验研究,通过改变pH值、搅拌时间和膨润土的投加量,确定适宜的操作条件.实验结果表明:在pH为6,搅拌时间为20min,膨润土投加量为60g/L条件下,膨润土对水中磷去除率可达到85%.

The absorption of phosphorus of water on bentonites is examined. The suitable operating conditions are determined by changing pH value, time of stiring and quantity of throwing bentonites. The results show that when pH value is 6, time of stiring is 20 minutes, quantity of throwing bentonites is 60g/L, the rate of removing that bentonites absorbed phosphorus of water may reach 85%.
