摘要
叙述了磷酸铵镁在废水中的形成机理及其在废水处理中的应用现状。在废水处理中利用镁盐作沉淀剂可以同时去除废水中的氮和磷,该方法去除率高、反应速度快、污泥体积小,同时还可回收磷酸铵镁,具有一定的应用前景。
The mechanism on the formation of magnesium ammonium phosphate (MAP) in wastewater and its application in wastewater treatment were discussed. Use of magnesium salt as settling agent was able to remove simultaneously the nitrogen and phosphorus from wastewater. The technology was characterized by high removal efficiency, rapid reaction rate, and small sludge volume, with recovery of MAP. The process has some prospect in application.
