The invention relates to a light /
ozone-
electricity-
adsorption reaction device and method for extracting
copper by degrading
browning waste liquor. The device comprises a light /
ozone synergistic decomposing device, an
electrolysis device for degrading and recovering
metal copper and an adsorption
elution device. In the device, a photocatalyst and an
oxygen catalyst are loaded on a porous
activated carbon carrier with high specific surface area; under the synergistic effect of
ultraviolet light and
ozone, photo-generated
electron pairs are prevented from compounding, long-time catalytic treatment activity is kept, a free radical.OH with strong
oxidation activity is generated, organic matters in the
browning waste liquor can be oxidized and degraded, and the complexing bond of the complex in the
browning waste liquor can be broken; insoluble reticular
titanium base material serves as an
anode, a
copper sheet material serves as a
cathode, organic matters in the browning liquor is continuously degraded by
electrolysis to generate a second-grade degrading product which is easy to adsorb, and valuable
metal copper is recovered on the
cathode; and finally, common
activated carbon is used for adsorbing to effectively treat the browning waste liquor, so as to realize green and environment-friendly treatment of the browning waste liquor.
