After that, the chemical wastewater enters the discharge frame 10 filled with chemical reagents from the switch valve 9, and the chemical wastewater reacts with the chemical reagent to achieve denitrification. Finally, the denitrified chemical wastewater flows into the water outlet frame 11 and is discharged by the water outlet valve 12.
