摘要
MAP法(磷酸铵镁沉淀法)是去除废水中高浓度氨氮的一种有效技术。本文叙述了MAP法去除废水中氨氮的反应机理,分析pH值、物质摩尔比,反应时间等影响因素。该方法具有去除率高、反应速度快、受外界环境影响小等特点,同时还实现了对氮的有效回收,具有较好的应用前景。
The method of magnesium ammonium phosphate（MAP） is an efficacious technology to remove high strength of ammonia-nitrogen from the wastewater.This paper introduces the reaction mechanism of MAP methods and analyzes factors affecting the result including pH value,molar ratio and reaction time.The technology has advantages such as high removal efficiency,rapid reaction rate and low external environment influence.Additionally,ammonium is recovered effectively in the process.It must have bright prospects in future application.
