Treatment of Phenol WasteWater with Modified Coal Fly Ash-Fenton Reagent

Abstract:

Autonomous coal fly ash modified by vitriol (H₂SO₄) was used to treat Phenol Waste Water. The treatment influences were determined by single-factor experiment and the prioritizing importance and optimizing combination of the influences were studied using orthogonal experiment. We found that the prioritizing importance of the influencing factors was as follow: dosage of ferrous sulfate (FeSO₄) > dosage of hydrogen peroxide (H₂O₂) > initial concentration of phenol > PH > the dosage of modified coal fly ash. The optimizing combination of the influences was 5 wt.% FeSO_4, 1 mL ; 3 wt.%H₂O₂, 7 mL; PH=5; initial concentration of phenol , 300 mg/L and the dosage of modified coal fly ash, 200 mg/L. Under the condition above, phenol removal rate was 99.46%.
