High Turbidity Mine Water Treated by Magnetic Flocculation

In the paper, magnetic flocculation was used in high turbidity mine water treatment. The results show that the magnetic flocculation is one of efficient methods in removing the COD and SS of high turbidity mine water. It Finds the optimal conditions: the PAFC was 30ing/L and added with the fast stirring speed being 250r/min for 2min; then, 50mg/L magnetic particle was added with slow stirring speed staying 50r/min for 7min. The wastewater is treated under the optimal condition, the removal efficiency of SS and COD reached 94% and 71% respectively.
