| Abstract: | The properties of 2-naphtholwastewater were studied in details in this paper, the wastewater was characterized by the strong acidity, high buffer capability and concentrated salt. Air oxidation and anion exchange were employed for the treatment of the wastewater. Under formal pH, room temperature and 1BV/h rate, the result showed that the removal of COD reached to 97% and the recovery of sodium naphthalensulfonate to 98%. Besides, wastewater treated can be reused for washing the sodium naphthalensulfonate. |
