| titleOfInvention | Method for treating sulfanilamide mother liquor |
| abstract | The invention relates to the technical field of wastewater treatment, and particularly discloses a method for treating sulfanilamide mother liquor, which comprises the steps of recovering sulfanilamide, separating salts, polymerizing and separating organic matters and performing biochemical treatment, wherein sulfanilamide in the mother liquor is adsorbed by resin, and sodium chloride and sodium acetate in the mother liquor after sulfanilamide is recovered are separated by MVR evaporation equipment; adding a condensing agent into the mother liquor after salt separation; and finally adding microorganisms for biochemical treatment. The treatment process of the invention can reduce the COD of the final sulfanilamide mother liquor to below 500mg/L, and reaches the environmental-friendly discharge standard. |
