摘　　要：吸附法一直是处理磷废水的重要方法,被认为是能够很好地适用于宽浓度范围废水除磷的方法。本文采用三种金属氧化物作为吸附剂(活性氧化铝、水合氧化镧、新型稀土铈铁复合吸附剂)进行吸附除磷静态试验,考查在不同的条件下(吸附时间、温度、pH值)吸附剂对磷的吸附效果。本文为开发高效除磷吸附剂提供了有价值的参考依据,在防治水体富营养化方面具有广阔的前景。The adsorption method has been an important method to deal with phosphorus waste water all the time,which is considered to be the thing that can be well suitable for the waste water of wide density range and get rid of the phosphorus method.This literary use three kinds of metal oxides as absorbent(active alumina,hydration oxidize lanthanum,new-type tombarthite cerium iron compound the absorbent) to absorb and get rid of the phosphorus static test,And examine the result of absorbing to the phosphorus of absorbent under different conditions(absorbs time,temperature,pH value).This text has offered the valuable reference basis for developing and getting rid of the phosphorus absorbent high-efficiently,have a wide prospect in preventing and curing water body eutrophication.
