Abstract

The invention discloses a pulse fluidized bed electrode device. The structure of the pulse fluidized bed electrode device comprises a liquid supply system, a fluidized bed and an electrode system, wherein the liquid supply system is composed of a liquid storage trough, a magnetic pump, a piston pump and a rotor flow meter, the fluidized bed comprises a rectangular bed body and a pre-distributor, and a fluidized liquid outlet is formed in the side wall of the upper part of the bed body; and a material outlet is formed in the sidewall of the lower part of the bed body, and the electrode system is composed of a DC stabilizing power source, an anode plate, a cathode plate and an anode membrane. The device is suitable for electrolysis of heavy metal ion-containing wastewater, dead zones, channeling, particle bonding and other bad phenomena during fluidization are reduced or eliminated, the current efficiency and space-time efficiency of the fluidized bed electrode are improved, and the treatment cost of the heavy metal ion-containing wastewater is reduced.

Description

technical field [0001] The invention belongs to the technical field of electrochemically treating wastewater containing heavy metal ions, and relates to a fluidized bed electrode device. Background technique [0002] Mining, metallurgy, electroplating, electronic product manufacturing, printing and dyeing, and pesticide industries will produce a large amount of heavy metal ion wastewater. These wastewater containing heavy metal ions enter the water body and soil, which will inhibit the growth and reproduction of organisms and destroy the ecological cycle. And because the heavy metal ions discharged into the environment cannot be biodegraded or converted into harmless substances, they accumulate in animals and plants, and finally enter the human body through the food chain, which will seriously endanger people's health. Therefore, it is of great practical significance to develop an efficient and economical treatment and recovery technology for heavy metal ion wastewater. [...
