It is pointed out that under the condition of the temperature of 1120℃, the reaction time of 16 mm and the carbon content of 27%, the metal transformation rate of sponge iron used for general metallurgy is up to 90%. But the optimal carbon content is 29% for iron sponge to treat DSD acid oxidation wastewater. Under condition of the wastewater's pH value of 3 to 5 and the reaction time of 40min, the removal rates of COD and color are 68% and 90%, respectively. The BOD/COD ratio is up to 0.425 when DSD oxidation acid water is treated with sponge iron.
