A combined process of catalytic ozonation in the presence of a novel heterogeneous catalyst and bio-logical activated carbon was investigated for the removal of priority control organic pollutants, the reduction of genotoxicity, and the improvement of biodegradable dissolved organic carbon(BDOC). Results confirm that the catalytic ozonation has higher effectiveness for the removal of refractory harmful organic pollutants, the reduction of genotoxicity and the increase of bio-degradability of organics than ozonation alone, which results in lower pol-lution load for subsequent biological activated carbon process, and then leads to less organic pollutants penetrat-ing biological activated carbon. The novel catalytic ozonation with this combined process exhibits excellent per-formauce to guarantee the safety of drinking water.
