| Abstract: | According to the characteristics of PVC wastewater,such as large discharge amount,low concentration and hard-degradation,a composite method with steam stripping and Fenton reagent oxidation was adopted to carry out the treatment of PVC wastewater.The effects of outlet flow,wastewater temperature,pH value,H2O2 dosage,Fe2+ dosage and reaction time on the removal rate of CODCr and energy consumption were discussed.The optimal conditions were obtained as follows:outlet flow was 0.5%,wastewater temperature was 9... |
