摘　　要：磷是日益枯竭的战略资源,同时又是造成水体富营养化的关键因素,所以从废水中回收并利用磷不但具有经济效益还具有环境效益。反应器是鸟粪石法回收磷的核心装置,国外在磷回收研究方面已研发了多种反应器,其中有些已用于实践中,并产生了很大的环境与经济效益。但在国内很少有关于磷回收反应器研究方面的详细报道。本文在阐述鸟粪石法回收废水磷原理的基础上,介绍了国内外从废水中回收磷所采用的反应器,包括机械搅拌和空气搅拌的搅拌式反应器,以及气体搅动式和液体搅动式的流化床式反应器,着重介绍各种反应器的结构流程以及研究现状。Phosphorus is an increasing depletion of strategic resource,and also is a key factor in eutrophication,so taking advantage of phosphorus from wastewater is provided with economic and environmental benefits.MAP reactor is the core unit of phosphorus recovery.There have developed a variety of research reactor on phosphorus recovery in foreign countries,some have been used in practice,and produce great environmental and economic benefits.However,there is rarely detailed report about the phosphorus recovery reactor research at home.In the paper,based on the principle of description recovery of MAP,introduced domestic and foreign reactor used in recycling of phosphorus from the wastewater,the summary can be classified into two types：mechanical mixing and air mixing reactors,and gas agitation and liquid agitation fluidized-bed reactors,focusing on the structure of the various reactor processes and research status.
