摘要
铵根离子可以和镁盐、磷酸根在适当的条件下生成磷酸铵镁沉淀,利用这一反应可以去除水中的氨氮。本文从磷酸铵镁的性质、反应机理、反应条件及沉淀剂循环利用等方面,对这一方法进行了介绍和总结,并对今后该技术发展提出了建议。
Ammonia can be removed from wastewater by forming magnesium-ammonium-phosphate （MAP） precipitate with magnesium salt and phosphate. In this paper the chemical and physical characters of MAP, practical application in wastewater treatment and recycling of precipitator are reviewed in details and some suggestions are given for further study.
