LOESS BALL FOR WATER TREATMENT AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: Provided is a loess ball as a water treatment agent capable of effectively eliminating phosphorous, dioxin and COD and further provided is a method for manufacturing the same. CONSTITUTION: The method comprises the steps of (a) crushing loess, (b) sorting out loess powder no greater than 500 μm, (c) drying the loess powder at a temperature of 80 to 130°C for 1 to 4 hours, (d) mixing the loess powder with porphyry powder and activated carbon powder, wherein a weight mixing ratio of the loess and porphyry is 10:1 to 20:1 and a mixing ration of the loess and activated carbon is 1:2 to 1:4, (e) adding water to the powder mixture and forming balls with a diameter of 0.1 to 10 mm using the mixture, and (f) calcining the balls at a temperature of 400 to 800°C for 5 to 25 hours.
