摘要
磷是一种不可再生、十分有限的资源,它的回收再利用已成为水处理工业关注的焦点。污水中的磷可以以磷酸盐沉淀的形式回收,其中以鸟粪石和磷酸钙的形式从污水中回收磷被认为是最具有前景的磷回收途径。作者对生成鸟粪石和磷酸钙的主要影响因素及鸟粪石和磷酸钙沉淀法在污水磷回收中的应用作了全面的概述,并对存在的问题作了简要分析。
Phosphorus is a kind of irregenerable and limited resource. Phosphorus recovery from wastewater has become a concerned focus in wastewater industry. Phosphorus can be recovered by way of phosphate sedimentation. Recovery of phosphorus in the forms of struvite and calcium phosphate is considered to be the most promising way. The influence factors and the application of struvite and calcium phosphate precipitation are reviewed and discussed, and the problems existing are analyzed as well.
