【摘要】 利用Fenton法对造纸废水生化出水进行深度处理,考察了废水pH值、反应时间、Fe-SO4投加量和H2O2投加量对废水中色度和CODCr去除率的影响,结果表明:在pH值为5.00、FeSO4投量为400mg/L、30%H2O2投量为200mg/L,反应时间为30min,出水CODCr可降至60mg/L以下,色度的去除率可达到74%,可以满足更为严格的造纸废水排放标准。更多还原

【Abstract】 Using fenton reagent in advanced treatment to process papermaking wastewater is studied in the experiment.Main factors effect the removal rate of CODCr and color,such as pH value,the reaction time,the amount of FeSO4 and the amount of H2O2 are discussed to achieve excellent effect.Results show that the optimum removal rate of color reached 74%,with pH=5.00,amount of FeSO4 =400mg/L,amount of H2O2=200mg/L,and reaction time is 30 min,at last CODCr is reduced to 60mg/L,which meet the stricter standard for discharge of papermaking wastewater.更多还原
