Experimental study of coagulant type on the efficiency of high suspended solids mine drainage
The typical high suspended mine water was selected to analyze the effect of PAC,PAM and FeCl3 on the efficiency of high suspended matter mine water treated by loading coagulation with heavy sand.The results showed that appropriate dosage of PAC contributed to improving the efficiency and rate of loading coagulation with heavy sand,while excessive PAC reduced.The addition of PAM improved the efficiency and rate of loading coagulation with heavy sand,while the effect of the dosage can be ignored.Appropriate amount of FeCl3 can effectively enhance the removal efficiency and rate of high suspended coal mine drainage suspended coal in mine water,while its effect on high suspended rock mine drainage was relatively weaker.These results can effectively ensure the efficiency of high suspended matter mine water treated by loading coagulation with heavy sand and provide the comprehensive utilization of water resources in coal mining China.
