Summary: | The invention provides a device for treating sodium acetate waste residues. The device comprises a diffusion dialysis device and a bipolar membrane electrodialysis device. The diffusion dialysis device and the bipolar membrane electrodialysis device are connected through a recycling solution tank. The invention further provides method for treating sodium acetate waste residues generated in the dithianon production process by means of the integration device comprising the diffusion dialysis device and the bipolar membrane electrodialysis device. In the treatment process of sodium acetate waste residues, firstly, the diffusion dialysis device is used for performing separation and purification on the sodium acetate waste residue solution, the sodium acetate recycling solution with the high purity is obtained and then treated through the bipolar membrane electrodialysis device, and finally acetic acid and sodium hydroxide are obtained; accordingly, the DD-BMED integrated continuous process is formed, discharge of |
