| Abstract: | An improved method to treat dye wastewater using iron scraps was presented Analysis was given to the mechanism of the process The result showed that when the pH value was 4 0, the time of treatment was 30 minutes,the amount of iron scraps and fly ash were 5% and 6% respectively, COD was reduced to under 400mg/L, the removing rate and decoloring rate were over 77% and 95% It was proved that this method was highly effective and feasible for pretreatment of dye wastewater |
