摘　　要：研究了用化学沉淀剂除去废水中的氨,探讨了不同沉淀剂如Mg(OH)_2+H_3PO_4或MgHPO_4,不同初始Mg(OH)_2:H_3PO_4摩尔比,不同pH值及初始氨浓度对氨除去效率的影响。Ammonia removal in wastewater by a chemical precipitant was studied in this paper. The effects of different precipitants such as Mg(OH)2 + H3PO4 and MgHPO4,different initial molar ratios of H3PO4 to Mg(OH)2,different pH on the ammonia removal efficiency were discussed.
