| 摘 要： | 合成氨废水具有高氨氮的特点,高氨氮污水的治理是大家关注的焦点。文章介绍处理高氨氮废水的三种资源化回收技术,(1)以氨水形式回收氨氮的废水处理技术;(2)将氨氮制成硫酸铵回收利用的废水治理技术;(3)既能高效脱氮又能充分回收氨氮的磷酸铵镁(俗称鸟粪石)结晶沉淀法,其中重点介绍鸟粪石结晶沉淀法回收氨氮技术。这些废水处理技术有效地治理了高氨氮废水,具有节能减耗、无二次污染和污染物可得到充分回收利用等特点,是处理高浓度氨氮废水的可持续发展方向。

| Abstract: | Current development of technologies for treating synthetic ammonia wastewater is reviewed with particular concerns in resource reuse from the wastewater.Three approaches are described,including ammonia-nitrogen recovered as aqueous ammonia from the wastewater,ammonia-nitrogen converted into (NH4)2SO4 and high efficiency both in de-nitrification and ammonia-nitrogen recovery through struvite precipitation.Method of struvite precipitation is intensively recounted regarding precipitant selection,dosing and the... |
