The invention discloses an AO-electrocatalytic oxidation combination percolate treatment device and technology for a rubbish transfer station, and belongs to the field of rubbish percolate treatment devices. According to the device, firstly, rubbish percolate is subjected to biochemical pollutant degradation through anaerobic and aerobiotic units, then electrocatalytic oxidation is completed in anelectrolysis unit to further reduce pollutants and improve the biomedical performance of the pollutants, and finally, in order to strengthen the integral treatment performance of the technology, partial discharged water of the electrolysis unit newly flows back to the anaerobic unit for biochemical degradation again. Compared with a traditional single three-dimensional electrode treatment technology or a traditional single AO treatment technology, the technology is better in percolate treatment effect of the rubbish transfer station for rubbish of villages and small towns.
