The invention relates to a hydrogenation catalyst regeneration wastewater treatment method, belonging to the technical field of wastewater treatment. The filtrate is secondary wastewater, and the filter cake is transferred to the washing kettle; water is added to the washing kettle, and the filtrate is filtered after stirring. It is a tertiary wastewater, the filter cake is dried to obtain a regenerated hydrogenation catalyst, the primary wastewater, secondary wastewater and tertiary wastewater are merged into the wastewater treatment tank, and modified titanium dioxide is added, treated under the irradiation of LED ultraviolet light, filtered, The filter cake is processed in the next step, and the filtrate is discharged normally. The present invention adds modified titanium dioxide to the hydrogenation catalyst regeneration wastewater, which can effectively reduce the content of pollutants in the regeneration catalyst wastewater. |
