| Abstract: | NaClO /Fe2+ oxidation method is used to treat pulping and papermaking wastewater,which is pre-treated by anaerobic and aerobic process.The effect of the main factors on COD removal of the wastewater is investigated by orthogonal and single factor experiment to determine the optimum process conditions.The results show that the effect of NaClO /Fe2+ oxidation on the COD removal in the following order: NaClO dosage > Fe2+ dosage > reaction time.After 30 min NaClO /Fe2+ oxidation reaction and under the operation conditions of influent COD 340 mg/L,pH 7～8.3,the dosage of 10% industrial grade NaClO 2.5 mL/L and the amount of FeSO4 6 mmol/L,77.87% of COD is removed and the effluent COD concentration drops to below 76 mg/L,which has achieved the limits requirements of COD discharge concentration 80 mg/L in GB3544-2008 "Water Pollutant Discharge Standards of Pulp and Paper Indastry". |
