Struvite chemical crystallization technology has received extensive attention by domestic and for‐eign scholars for the property of resourceful recycling and utilization of ammonium and phosphorus. The mecha‐nism of struvite crystallization and the influencing factors during the process of ammonium sedimentation were introduced; besides, the nucleation induction process of struvite crystallization was elaborated. The influences of pH value, temperature, drugs addition ratio and interfering ions on struvite were analyzed, it was pointed out that, pH value and addition ratio of drugs were the most two important factors influencing struvite crystallization.
