摘要
磷是一种不可再生而又面临枯竭的重要资源。概述鸟粪石沉淀回收污泥中磷的基本原理,污泥中磷的释放方法,综述液相中磷以鸟粪石沉淀法回收的影响因素。指出目前工艺中存在的问题以及新的研究方向。
Phosphorus is a nonrenewable and limited resource. The mechanism of phosphorus recovery through slruvite precipitation method and approaches to releasing phosphorus from P-rich sludge are reviewed.The influencing factors of phosphorus recovery as struvite form supematant are summerized. The problems in the process and new research trend of phosphorus recovery from struvite are indicated.
