摘　　要：磷是自然界与人类社会都离不开的重要的不可再生资源。剩余污泥中富含大量的磷,对剩余污泥进行预处理释磷,并研究这一过程中不同形态磷的迁移转化,最终通过磷回收工艺实现磷资源回收利用是非常必要的。回顾了含磷污泥预处理及磷回收的技术方法及优缺点,以期为污泥磷回收的研究提供借鉴。Phosphorus is an important non-renewable resource that is inseparable from nature and human society.The surplus sludge is rich in phosphorus.It is necessary to preprocess the surplus sludge to release phosphorus and study the migration and transformation of different forms of phosphorus in this process.Finally,it is very necessary to realize the recovery and utilization of phosphorus resources through the phosphorus recovery process.The technical methods and advantages and disadvantages of phosphorus-containing sludge pretreatment and phosphorus recovery are reviewed,in order to provide a reference for the research of phosphorus recovery from sludge.

关 键 词：剩余污泥 预处理 磷回收
