Abstract
The invention discloses a treatment method for mine wastewater and a device thereof, aiming at solving the problem that the existing mine wastewater treatment methods and devices can not treat pollutants thoroughly and can not recycle noble metals. The treatment method is as follows: pumping raw water into a bag filter (11), and removing off large particles and suspended matters, and mineralizing, modifying and decomposing the treated water by an advanced oxidation device (6), wherein the treated water enters a multimedia absorber (4) then to absorb surplus oxidizing substances; then, guiding water into an ultrafiltration device (14) to filter off colloids and macromolecules in water, wherein the water after passing through the ultrafiltration device (14) enters a reverse osmosis device (1) through a high-pressure pump to be concentrated and separated; finally, respectively discharging standard water and concentrated solution. Therefore, the treatment method and the device have advantages of treating pollutants thoroughly, recycling noble metals and so on.
