The removal effect of flocculant and coagulant aid on raw water turbidity was studied by conducting filtration experiment on the developed mine precision water filter. The filtration effects of fiber ball filter material, comet type fiber filter material and new comet type fiber filter material were compared and analyzed, the influence characteristics of operating pressure and filtration speed of the filter on the effluent water quality were studied, and the influence rules of influent water turbidity and filter height on the pressure loss were discussed.The results show that the flocculation effect is the best and the raw water turbidity removal rate is the highest when the flocculant and coagulant aid dosage of 5 mg/L and 1 mg/L respectively; the new comet type fiber filter material has the best filtering effect;when the filter pressure is 0.2~0.6 MPa and the filtration speed is 38 m/h, the filter bed is formed quickly, the effluent water quality is stable and the turbidity is less than 1NTU;the pressure loss of the filter bed increases with the time when the inlet water turbidity increases, which leads to shorter filtration cycle; the pressure loss decreases with the increase of filter height.The experimental results provide a basis for the development and technical popularization of the mine water treatment equipment
