Dimethylamine wastewater treatment method

The invention relates to the technical field of wastewater treatment, in particular to a dimethylamine wastewater treatment method. The dimethylamine wastewater treatment method comprises the following steps: A) adjusting the pH value of the dimethylamine wastewater to 2-5; b) under the condition of aeration or stirring, adding ferrous sulfate and hydrogen peroxide into the wastewater obtained inthe step A) for reaction; and C) stopping aeration and stirring, adjusting the pH value to 7-10, and filtering to obtain the treated water body. By controlling the addition amount of the oxidant hydrogen peroxide, amido in dimethylamine is oxidized and dissociated into ammonia nitrogen and is further oxidized into nitrogen, so that total nitrogen in the dimethylamine wastewater is effectively removed. 本发明涉及废水处理技术领域，尤其涉及一种二甲胺类废水的处理方法。所述二甲胺类废水的处理方法，包括以下步骤：A)调节二甲胺类废水的pH值为2～5；B)在曝气或搅拌的条件下，在步骤A)得到的废水中加入硫酸亚铁和双氧水进行反应；C)停止曝气和搅拌，调节pH值至7～10，过滤后，得到处理后的水体。本发明通过控制氧化剂双氧水的加入量，使二甲胺中的胺基氧化游离成氨氮，并进一步氧化成氮气，从而有效除去二甲胺类废水中的总氮。
