摘要：

以活性炭吸附和Fenton氧化技术处理含盐有机废水。结果表明，活性炭预处理过程中，当废水pH为6时，投加8 g/L的活性炭，30 min后COD去除率达到66.8%，活性炭预处理后，投加12 mmol/L FeSO₄·7H₂O、240 mmol/L 30% H₂O₂，30 min后COD去除率达到82.4%；Fenton氧化技术直接处理废水时，调节废水pH为6，FeSO₄·7H₂O和30% H₂O₂分别为15 mmol/L和300 mmol/L时，COD去除率为41.3%，继续投加8 g/L活性炭，30 min后COD去除率达到78.8%。

Abstract:

Organic saline wastewater was treated by activated carbon adsorption and Fenton oxidation. Results showed that in the activated carbon pretreatment process, when wastewater pH and activated carbon dose was 6 and 8 g/L, the COD removal efficiency reached 66.8% after 30 min reaction. When FeSO₄·7H₂O and H₂O₂(30%) were then added as 12 mmol/L and 240 mmol/L into the effluent after pretreatment, it even could reach 82.4%. While directly treated with Fenton oxidation technology, with wastewater pH of 6, dosage of FeSO₄·7H₂O and H₂O₂(30%) 15 mmol/L and 300 mmol/L, COD removal efficiency reached 41.3%. By then adding 8 g/L activated carbon, the COD removal reached 78.8% after 30 min adsorption.
