AI Technical Summary
The treatment of sludge filtrate involves high energy consumption, large amounts of flocculants, and significant impact on the operating load of wastewater treatment plants. Existing technologies are insufficient for the efficient degradation of organic pollutants.
A hierarchical porous carbon catalyst was prepared as the anode. The organic matter in the sludge filtrate was oxidized by activated oxygen molecules under ambient temperature and pressure using electrically driven CWAO technology. The porous carbon material formed by combining MOF material and graphite felt, with its microporous and macroporous structures, achieved uniform dispersion of catalytic active sites and efficient mass transfer of reactants.
The COD removal rate of sludge filtrate reached 82.8% within 2 hours, which improved the degradation efficiency of organic pollutants, reduced energy consumption and flocculant dosage, and reduced the load impact on the sewage treatment plant.
