摘要

摘要:
利用椰壳活性炭（CSCC）对铜尾矿氧化焙烧释放的SO_x被收集形成的含硫废水进行静态吸附。研究了CSCC对SO₄^2-的吸附处理性能，计算了SO₄^2-的吸附效率，探讨了CSCC的最优使用量、温度、吸附的时间和最优pH值。结果表明：活性炭的最优使用量为2.5 g，最优吸附温度为70 ℃，最优吸附的时间为3 h，最优pH值为7，吸附效率达到96.19%。该研究为CSCC处理含硫废水的实际应用和研究提供了一定的技术参考和依据，对含硫废水的无害化处理和排放有一定的借鉴意义。

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.
