Experimental study of fenton′s reagent and zeolite with fly ash treaed citric acid wastewater

In this paper, it conducts the fly ash handles zeolite Fenton's reagent citric acid oxidation of process wastewater technological experiments. It inspected the temperature, fly ash dosage zeolite adsorption time on the effect of treatment, and Fenton's reagent alone with the fly ash handling and processing of zeolite with the effect of contrast. The results showed that the removal rate of wastewater CODcr reached 97.26%, in the conditions of 20 C, the quality of fly ash zeolite concentration of 3 g/l and 30 min of adsorption. It was better than Fenton's reagent dealing separately, in the dealing with efficiency and stability.
