磷矿是有限的资源，由于人类的过度开发利用，储存量逐年减少。而磷的过量排放又引起水体富营养化、导致赤潮等水域生态问题。从磷资源的有限储存量和含磷污水对自然环境的危害两方面综合考虑，从废水中回收磷是抑制磷在自然界中的单向流动而造成了磷资源枯竭的有效手段。污水回收磷的主要方法是采用化学沉淀法，其实质就是化学除磷。

Phosphorite is a limited resource. Due to over-exploitation, its storage capacity is decreasing. The excess emissions of phosphorus can cause eutrophication, lead to red tide and other water ecological problems. Considering limited storage capacity of phosphorite and harm to the natural environment of phosphorus-contai-ning effluent, recovery of phosphorus from wastewater is an effective means to control phosphorus resource de-pletion and one-way flow of phosphorus in nature. Chemical precipitation method is the main recycling method of phosphorus in sewage which is chemical phosphorus removal method.
