It mainly investigated some important factors on the treatment effect, such as the concentration of EDTA, the dosage of hydrogen peroxide(30%), the dosage of ferrous sulfate, pH, reaction time and reaction temperature. At last, the best conditions were obtained under the following: the concentration of EDTA was 0.10 mmol/L, the dosage of hydrogen peroxide(30%) was 15.00 mL/L, the dosage of ferrous sulfate was 1.50 g/L, the pH was 4, reaction time was 50 min, reaction temperature was 50 °C. The results showed that the removal rate of wastewater CODCr reached 80.05%. K
