| Zusammenfassung: | The invention discloses a manganese-containing wastewater treatment method which comprises the following steps: step 1, adding an oxidizing agent and an alkaline substance into manganese-containing wastewater after the manganese-containing wastewater enters a first reaction tank, and uniformly stirring to obtain a first manganese-containing mixed solution; step 2, after the first manganese-containing mixed solution enters a second reaction tank, adding a metal remover, and uniformly stirring to obtain a second manganese-containing mixed solution; and step 3, the second manganese-containing mixed solution enters a sedimentation tank, and mud-water separation is carried out. After the manganese-containing wastewater is treated, the manganese concentration of the effluent can reach the standard limit value of Integrated Wastewater Discharge Standard (GB 8918-1996). The manganese-containing wastewater treatment method disclosed by the invention is simple in process, high in medicament utilization rate and low in |
