Electroplating wastewater copper/nickel integrated circulation on-line recovery device

The utility model discloses an electroplating wastewater copper/nickel integrated circulation on-line recovery device which is formed by sequentially connecting a conditioning tank, an ion-exchange column, an intermediate tank, a reverse osmosis unit, a concentrated liquor tank and an electrolyzer. The device can implement integrated treatment and recovery on copper/nickel-containing electroplating wastewater, the treated wastewater has certain economic value, the whole device has reasonable layout, and the wastewater is discharged after reaching the standard, thereby implementing circulation flow of the high-concentration copper/nickel-containing electroplating wastewater, greatly reducing the contact with the external environment and reducing the pollution. Meanwhile, the device is provided with the on-line concentration probe and on-line pH value probe, and thus, can implement on-line monitoring.
