有机物对磷酸铵镁结晶影响的研究现状

Research Status of the Effect of Organic Matter on Magnesium Ammonium Phosphate Crystallization

磷酸铵镁(MAP)结晶法是有效去除和回收高氮磷废水中营养元素的技术之一,近年来受到越来越多的关注。本文在简要介绍MAP结晶法的基本原理和影响因素的基础上,着重评述和分析了有机物在其结晶过程中的影响和作用,总结了目前在这个研究方面的不足之处,展望了该方法的应用前景。

Magnesium ammonium phosphate （MAP） crystallization is one of the effective technologies for nutrients removal and recycling from nitrogen-and phosphorus-containing wastewater. More and more attentions have been paid to this field in recent years. In this paper, the basic principles and influencing factors of the struvite precipitation were reviewed briefly. And based on that, the effect of organic matter on struvite crystallization was discussed emphatically. Furthermore, the problems and the prospect were also proposed.
