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

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.
