Radiation-Assisted Waste Water Treatment Using Nanocatalyst and Fenton’s Reagent
Abstract
The effect of nanocatalyst and Fenton's reagent on the efficiency of wastewater treatment under the influence of γ-radiation was studied. Model samples of aqueous solutions of phenol were used for examining radiolytic decomposition patterns under the influence of γ-radiation (at doses in the range of 1.4–18 kGy) in the presence or absence of nano-γ-Al2O3 catalyst accompanied by in situ Fenton’s reagent formation. It was established that the addition of the nanocatalyst to the system resulted in an increase in the rate of phenol decomposition and an increase in the radiation-chemical yields of the radiolytic transformation. Industrial and municipal wastewater samples were applied for studying possibility of their biochemical treatment under the influence of γ-radiation in the presence of the nanocatalyst and a component of Fenton’s reagent system. Irradiation of wastewater samples taken from an oil refining enterprise led to an enhancement of water quality and a substantial improvement in bacteriological parameters (indicators of E. coli and total microbial count).
