英文摘要	The abatement of several emerging contaminants (ECs) in groundwater by conventional ozonation and three ozone-based advanced oxidation processes (AOPs) - catalytic ozonation with manganese dioxide (MnO2), conventional peroxone (O-3/H2O2), and electro-peroxone (EP) - was compared in this study. The addition of MnO2, H2O2, or electro-generation of H2O2 during ozonation enhanced ozone transformation to hydroxyl radicals to different extent. These changes did not considerably influence the abatement of ECs with moderate to high ozone reactivities (k(O3)>= 500M(-1)S(-1)), whose abatements were similar with> 90 % during all four processes. In comparison, the abatements of ozone-refractory ECs (k(O3) < 15M(-1)s(-1)) were lower during conventional ozonation (similar to 40-85 % abatement), but could be enhanced by similar to 10-40 % during the three ozone-based AOPs. Besides enhancing ozone-refractory EC abatement, the three AOPs, especially the O-3/H2O2 and EP processes, reduced considerably bromate formation compared to conventional ozonation. These results demonstrate that the EP process performs similarly as catalytic ozonation and O-3/H2O2 processes in terms of EC abatement and bromate control. Considering its more convenient, flexible, and safer way of operation, the EP process may provide an attractive alternative to the two more traditional AOPs for water treatment.
