Abstract

The invention discloses a device for simultaneously separating and recovering multiple heavy metals from electroplating wastewater. The device comprises a device outer frame comprising at least one treatment unit chamber, wherein an anodic reaction pool and a cathodic reaction pool are arranged in each treatment unit chamber, an anode plate is arranged in the anodic reaction pool, and a cathode plate is arranged in the cathodic reaction pool; a multilayered diaphragm comprising a cation exchange membrane and an anion exchange membrane is arranged between the anode plate and the cathode plate, a wastewater treatment channel is formed by the multilayered diaphragm, and an electroplating wastewater inlet and an electroplating wastewater outlet are formed in the device outer frame; the device is equipped with a direct-current power source, the anode plate and the cathode plate are correspondingly connected with a positive pole and a negative pole of the direct-current power source, and a metal recovery chamber is formed between the cation exchange membrane and the anion exchange membrane. According to a method for simultaneously separating and recovering multiple the heavy metals from the electroplating wastewater, heavy metal ions in the electroplating wastewater flowing through the wastewater treatment channel are separated and recovered in a form of metal or alkali compound from the electroplating wastewater in the metal recovery chamber formed through isolation.
