Beschreibung
Zusammenfassung:The invention provides an electroplating wastewater treatment method. The electroplating wastewater treatment method is characterized by comprising steps as follows: 1), electroplating wastewater is subjected to air flotation; 2), the wastewater after air flotation is subjected to contact oxidation; 3), a coagulant and coagulant aids are added to the wastewater after contact oxidation for primary coagulating sedimentation treatment, and a supernatant is taken and subjected to secondary coagulating sedimentation treatment by adopting the coagulant and the coagulant aids. The invention further provides an application of the electroplating wastewater treatment method in electroplating wastewater treatment. 本发明提供了种电镀废水的处理方法,其特征在于,所述方法包括以下步骤:1)对电镀废水进行气浮;2)对气浮后的废水进行接触氧化;3)向接触氧化后的废液加入混凝剂和助凝剂进行级混凝沉淀处理,取上清液,并使用所述混凝剂和助凝剂对所述上清液进行二级混凝沉淀处理。本发明还提供了所述电镀废水处理方法在处理电镀废水中的应用。
