磷酸铵镁除磷脱氮技术

Removal of Ammonium and Phosphate by Magnesium Ammonium Phosphate Process

氨氮和磷酸盐是水质富营养化的重要来源。对含磷和氨氮的废水采用镁盐作沉淀剂可同时去除废水中的氨氮和磷酸盐,生成可用作肥料的沉淀物——磷酸铵镁,简称MAP,去除率均可达90%以上。

Ammonium and phosphate are important causes of the eutrophication of water.The use of magnesium salt as a precipitant in the treatment of wastewater containing phosphate and ammonium can remove both ammonium and phosphate simultaneously,resulting in the formation of a sediment of magnesium ammonium phosphate, or MAP,which may be used as a fertilizer,at a removal rate over 90%.
