Abstract
It discloses to a device and a method for controlling pollutants in metal mine water resources cycling utilization. The device includes a multi-stage inflow constructed wetland (), in which one or more layers of the filler are laid, and water distribution pipes () are buried at different height levels in the filler layers for multi-stage inflow, so that the received basin water is allowed to flow through each layer of the filler to degrade or remove the pollutants. In the multi-stage inflow constructed wetland, the types of fillers, dosage ratio, particle size and filling height of fillers in each layer are specifically selected. Therefore, heavy metal adsorption, suspended matter filtration, organic matter degradation, dephosphorization and denitrification can be effectively realized in the multi-stage inflow constructed wetland.
