【 摘 要 】

There is large quantity of phosphorus in wastewater, which leads to the water eutrophication. Magnesium ammonium phosphate(MAP) crystallization is used to remove and recover phosphorus from wastewater, which can not only restrain the eutrophication, but also realize the sustainable utilization of phosphorus resource. The mechanism of MAP crystallization is introduced, the influencing factors of crystallization are analyzed, and application of MAP crystallization is reviewed. While, the study of MAP crystallization is still at the beginning stage and further researeh need to be done in China. What's more, the prospects for future development trend of MAP crystallization are also summarized, which might provide reference for removal and recovery of phosphorus.
