The invention relates to a mineral processing water treatment system integrating adjusting and impurity settling concentration functions. The invention aims at the treatment for mineral processing wastewater and belongs to the field of mineral processing wastewater treatment. The mineral processing water treatment system integrating adjusting and impurity settling concentration functions mainly comprises a regulating reservoir, a mud storage area, a thickener, a flow pusher, a liquid inlet, a water allocation plate, a liquid outlet and a mud outlet. The mineral processing water treatment system is used for adjusting the mineral processing wastewater while settling, concentrating and eliminating mass suspended solids in the mineral processing wastewater. The water quality and quantity of the wastewater can be adjusted while the precipitate in system is precipitated, concentrated and eliminated, so that the load of the subsequent process flow can be reduced. The regulating treatment, precipitation, concentration and elimination of the mineral processing wastewater are realized, the integration of the original system is optimized, a certain guarantee is supplied for better treatment of the subsequent process flow and the running cost of the subsequent treatment is saved.
