Abstract：Inthisstudy，asynchronizedoxidation-adsorptioprocesswasusedtotreatthe mixed wastewaterofpulpingandpaperaking wastewater after biochemical treatment. The effects of H2SO 4 ， H202 ，FeSO and Fenton adjuvant on removal of COD and operating cost were investigated.TeoptialoperatigparaetersofteprocssefurtrexploredbyesposeSufaceetodogesulssoe that the order of influence of various factorson the treatment efficiencywasFeSO 4- HSO ④ Fentonadjuvant>H2O2.The optimal reactionconditionwas that the dosage of FeSO4 was 7.4mL/L ，the dosage of H2O2 （mass fraction 27.5% ） was O.17 mL/L，the dosage of HSO ⋅4 （3 mol/L） was 2.0mL/L ，the dosage of CPAMwas 4 mg/Land the dosage of Fenton adjuvant was O.245 mL/L.The efluent COD cr predicted by the model was 30mg/L ，while the average effluent COD G of the verification experiment was 42mg/L ，which was satisfied to the standard GB3544—2O08 Discharge Standard of WaterPolutants forPulpand Paper Industry.The overalloperating cost per tonof water haddecreased byapproximately 14% ： Key words： oxidation-adsorption; pulp and paper wastewater; response surface methodology
