Zusammenfassung:	The present invention relates to a method for recovering copper from copper-containing wastewater, comprising: a step (S1) of supplying copper-containing wastewater to the inside of a fluidized bed reactor; a step (S2) of forming CuS particles inside the wastewater by adding sulfides to the copper-containing wastewater supplied inside the fluidized bed reactor; a step (S3) of growing the CuS particles as CuS crystals while the wastewater having the CuS particles in the (S2) step is re-circulated inside the fluidized bed reactor; and a step (S4) of recovering the CuS crystals formed in the (S3) step.
