The invention belongs to the field of wastewater treatment, and in particular relates to a method for treating non-ferrous metal smelting wastewater. The non-ferrous metal smelting wastewater is controlled to be pretreated at a pH of 9 to 11, and the pretreated wastewater is separated to obtain the pretreated wastewater; the pretreated wastewater is subjected to electrochemical oxidation treatment , and during the treatment process, the metal M salt solution is continuously transported between the plates and near the anode end; the metal M salt solution is an aqueous solution in which at least one ion of Fe and Al is dissolved, and its transport flow rate is 2～ 200mg/(L·min). The invention can synergistically realize the simultaneous and efficient treatment of various pollutants in the non-ferrous metal smelting wastewater, and can synergistically increase the efficiency, not only that, but also can effectively reduce the cost of materials and equipment. |
