摘要
磷酸铵镁结晶技术因具有资源化回收废水中的氮和磷的特点而受到国内外学者的关注。介绍了磷酸铵镁的结晶机制以及沉氨过程中的影响因素,阐述了磷酸铵镁晶体成核诱导过程,分析了磷酸铵镁结晶过程中pH值、温度、药剂投加比例以及干扰离子对磷酸铵镁的影响,指出了pH值和药剂投加比例是磷酸铵镁结晶过程中最重要的2个影响因素。
Struvite chemical crystallization technology has received extensive attention by domestic and foreign scholars for the property of resourceful recycling and utilization of ammonium and phosphorus. The mechanism 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.
