| Abstract: | The research on the process
conditions of removing manganese and ferrum pollution from industrial cooling water by the
contact oxidation using the natural manganese sand filtering material is conducted.The particle
size of the filtering material is 0.51.0mm and the height of the filtering bed is 8mm;the filtering
speed,the working cycle,the back washing strength and back washing time are
1012m/h,96hrs,13L/m\+2 and 57min respectively.Mn\+\{2+\} concentration of the effluent is less
than 0.04mg/L.The removal rate is up to over 80% and the overall Fe concentration is in such a
low level that is not detectable. |
