In this paper the phosphorus removal from a real anaerobic supernatant through the crystallization of struvite and or hydroxyapatite was investigated. A comparison between experimental results on phosphorus crystallization carried out in a fluidized-bed reactor (FBR) on a bench-scale and on a half-scale plant is presented, together with a double saturational model able to describe all experimental results, independent of the different geometry of the reactors, the distinct contact times and the unlike products obtained. Experimental results show that removal efficiencies are very satisfactory, and the maximum phosphorus removal is of 80%.
本文研究了通过鸟粪石和/或羟基磷灰石结晶从实际厌氧上清液中去除磷的方法。文中给出了在实验室规模的流化床反应器（FBR）和半规模工厂中进行的磷结晶实验结果的比较，以及一个双饱和模型，该模型能够描述所有实验结果，而不受反应器不同几何形状、不同接触时间和所获得不同产物的影响。实验结果表明，去除效率非常令人满意，最大磷去除率为80%。
