AI Technical Summary
Existing technologies have failed to effectively utilize Fenton sludge generated during the treatment of hot rolling sludge and coking wastewater in the steel industry to prepare ozone catalysts, resulting in resource waste and environmental pollution.
An ozone catalyst with a microporous structure was prepared by drying, crushing, acid-adding stirring, granulating, and high-temperature carbonization of hot-rolled sludge and Fenton sediment, thereby improving the porosity and catalytic activity of the catalyst.
The reduction, resource recovery, and harmlessness of hot-rolled oil sludge and Fenton sediment were achieved, and a low-cost ozone catalyst with excellent catalytic performance was obtained, which improved the removal efficiency of organic matter in wastewater.
