Teatment of regeneration wastewater of ion-exchange resin in oil refining plant with fenton agent

摘要

The study took advantage of the catalytic oxidation treatment to deal with the regeneration wastewater of ion-exchange resin from the oil refining plant with the reagent Fenton and examine the results of the removing of the CODCr in the wastewater. The experiments showed that the effects are the best when the mole ratio between H2O2 and FeSO4·7H2O is 5:1, H2O2 (30%) is 50 ml/L, the pH is 3.5 and the reaction time is 2 hours. And we got to know how the various reaction factors affect the results of the removing of the CODCr in the wastewater through the orthogonal test.
