Abstract

Abstract

CSCC is used to statically adsorb the sulfur-containing wastewater formed by the collection of SO_x released by the oxidation and roasting of copper tailings. The adsorption treatment performance of CSCC on SO₄^2- was studied, and the adsorption efficiency of SO₄^2- was calculated. The optimal usage, temperature, adsorption time and optimal pH value of CSCC were discussed. Results showed that the adsorption efficiency can reach 96.19% with the activated carbon optimal amount of 2.5 g, the optimal adsorption temperature of 70 ℃, the optimal adsorption time of 3 h, and the optimal pH of 7. This research provides a certain technical reference and basis for the practical application and research of the sulfur-containing wastewater treatment by CSCC. It also has certain reference significance for the harmless treatment and discharge of sulfur-containing wastewater.
