The invention discloses a device for regenerating powdered
activated carbon. The device has a square plane shape, and is provided with a water inlet area, an
electrochemical regeneration area, a flow guiding area, a water outlet area, a
precipitation separation area and a
storage area from the center to the periphery, a water and carbon inlet
pipe is arranged below the water inlet area, and
electrolyte and saturated powdered
activated carbon to be processed enter the water inlet area through the water and carbon inlet
pipe and pass through the
electrochemical regeneration area, the flow guiding area, the water outlet area, the
precipitation separation area and the
storage area sequentially; after the regeneration process is finished,
produced water is discharged through a main water drain
pipe, and regenerated powdered
activated carbon is discharged through a regenerated carbon
discharge pipe; a
boron doped
diamond positive pole and a stainless steel negative pole are arranged in the
electrochemical regeneration area; a perforated aerator pipe, a mud bucket and the regenerated carbon
discharge pipe are arranged in the
storage area. According to the device, the regeneration and the
precipitation separation of powdered activated carbon are integrated, and the regeneration of powdered activated carbon is realized by intermittent operation, and the utilization ration of activated carbon is improved.
