▎ 摘　　要

NOVELTY - Device comprises an anode chamber connected with the anode of the power supply and a cathode chamber connected with the cathode of the power supply. The anode chamber and the cathode chamber are processed with wastewater containing heavy metal through flow electrochemical reaction. The anode chamber is used for breaking the wastewater. The cathode chamber generates hydrogen peroxide in situ, and activates permanganate, and generating manganese dioxide to absorb the heavy metal. USE - The device is useful for removing heavy metal in wastewater by electrochemical method. ADVANTAGE - The device: removal rate of chromium far exceeds and can be seen from the graph that compared with the control group; and increases removal rate of heavy metal chromium from about 10-20% to about 90%, with a maximum of 93.21%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for removing heavy metal in wastewater by electrochemical method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of device for removing heavy metal in wastewater by electrochemical method.
