Catalytic ozonation pilot-scale demonstration equipment (a). Changes in long-term water quality indexes, including chemical oxygen demand (COD) (b), total organic carbon (TOC) (c), and ozone-utilization efficiency (d) by the catalytic ozonation of PSE. Reaction conditions: catalyst filling rate = 50%, O3 dosage = 50 mg L−1 h, O2 flow rate ≈ 20 L min−1, influent flow rate = 180 L h−1, hydraulic retention time = 0.95 h, pH not adjusted. The error bars in (b−d) represent the standard deviations of triplicate tests. Source data are provided as a Source Data file.
