摘要
采用磷酸铵镁沉淀法处理含氮磷的废水,具有氮磷去除率高,反应速度快的优点;同时,回收氮磷生成的磷酸铵镁是一种缓释肥,具有良好的经济效益。系统论述了磷酸铵镁沉淀法回收氮磷的基本原理、影响因素、应用现状以及技术经济,并探讨了该技术在今后的研究发展趋势。
Removal and recovery of nitrogen and phosphorus from wastewater by struvite crystallization, which has the advantages of high removal rate and rapid reaction rate. Moreover, struvite recovered from waterwater is a slow-release fertilizer and has high economic benefit. This paper presents the basic theory and the influence factors of struvite formation, struvite application and technico-economic analysis. The study trend of this technique is discussed in the end.
