Poly-ferric-aluminum-silicate-sulfate was synthesized by using sodium silicate, ferric sulfate and aluminum sulfate as materials. With single factor analysis and orthogonal experiment, the optimum coagulation parameters of PFASS have also been discussed. The results indicated that the best parameters were molar ratio (Al + Fe)/Si 1.2, reaction temperature 60°C, reaction time 10 min, dosage of poly-ferric-aluminum-silicate-sulfate 20 mg/L, the best flocculation results can be achieved (the removal rate of turbidity to coal slime water was up to 96.2%) under these conditions.
