主 题:granular activated carbon regeneration dielectric barrier discharge plasma phenoldegradation bipolar pulse power
摘 要:A combined method of granular activated carbon(GAC) adsorption and bipolar pulse dielectric barrier discharge(DBD) plasma regeneration was employed to degrade phenol in *** being saturated with phenol,the GAC was filled into the DBD reactor driven by bipolar pulse power for regeneration under various operating *** results showed that different peak voltages,air flow rates,and GAC content can affect phenol decomposition and its major degradation intermediates,such as catechol,hydroquinone,and *** higher voltage and air support were conducive to the removal of phenol,and the proper water moisture of the GAC was 20%.The amount of H2 O2 on the GAC was quantitatively determined,and its laws of production were similar to phenol *** the optimized conditions,the elimination of phenol on the GAC was confirmed by Fourier transform infrared spectroscopy,and the total removal of organic carbons achieved 50.4%.Also,a possible degradation mechanism was proposed based on the HPLC ***,the regeneration efficiency of the GAC was improved with the discharge treatment time,which attained 88.5% after 100 min of DBD processing.
