Abstract本发明是一种多技术组合处理可生化性差的高浓度氨氮废水的方法,属废水处理技术领域。其特征在于:氨氮废水先进入pH调节池调节pH值为11~12.5,然后进入吹脱塔于气液比为3000~4500下进行吹脱,吹脱后废水再进入化学沉淀池,按Mg∶N∶P的摩尔比为1.4~1.7∶1∶1加入镁盐和磷酸盐,反应生成磷酸铵镁沉淀去除氨氮,出水再进入折点氯化池,按有效氯与氨氮重量比Cl/N为9~12∶1加入含氯氧化剂,反应后再转至还原池,按与余氯完全反应的理论摩尔值的1~1.1倍加入还原剂,反应后废水可直接排放。本发明方法操作简单,反应速度快,废水处理成本低,可使氨氮得到回收,不给环境造成二次污染,出水可达到一级排放标准。
