废水处理氨氮技术研究

Study on the Ammonia-Nitrogenium Skill for the Treatment of Wastewater

水中的氨多以氨离子(NH4+)和游离氨(NH3)的状态存在,两者保持平衡关系为NH3+H2O→NH4++OH-这一平衡关系受PH值影响,在不同PH值和水温条件下,游离氨易于水中逸出,只要采用一般的空气吹脱技术,可以达到除氨目的。

In the water, ammonia mainly exists in the form of NH4^＋ and NH3, between which there is a balance ： NH3 ＋ H2O→ NH4^＋ ＋ OH -. However, such balance is affected by PH value. Under the condition of different Ph values and water temperatures, ammonia is the free form can escape from water. Only by adopting ordinary air - blowing skill, can we get the aim of ammonia - removing.
