| titleOfInvention | Treatment method and system for removing total zinc and total organic carbon in cold rolling zinc-containing wastewater |
| abstract | The invention belongs to the technical field of water treatment, and particularly relates to a treatment method and a system for removing total zinc and total organic carbon in cold-rolled zinc-containing wastewater, wherein the cold-rolled zinc-containing wastewater enters a modified coconut shell activated carbon adsorption tower through a water inlet pump, modified coconut shell activated carbon is placed in the modified coconut shell activated carbon adsorption tower, and after passing through the modified coconut shell activated carbon adsorption tower, the cold-rolled zinc-containing wastewater enters a modified imino crosslinked chitosan resin adsorption tower; and the cold-rolled zinc-containing wastewater passes through a modified imino crosslinked chitosan resin adsorption tower and is discharged by a drainage pump after reaching the standard. After the cold rolling zinc-containing wastewater is treated by the process, the effluent quality of the cold rolling zinc-containing wastewater is that the pH is 7.7-8.6, the total zinc is 0.3-0.8 mg/L, and the total organic carbon is 4-8 mg/L. |
