摘　　要：为探究如何有效去除工业废水中的有机硫化物,以光催化氧化法为基础,通过简单的机械搅拌,在室温条件下合成了季铵型磷钨酸离子液体催化剂,并在甲酸-过氧化氢氧化体系下进行有机硫化物的降解试验。试验结果表明,本次设计的基于离子液体催化剂的光催化氧化法在去除工业废水中的有机硫化物过程中取得了较优的性能,有望在实际生产中逐步推广应用。In order to explore how to effectively remove organic sulfides from industrial wastewater,a quaternary ammonium phosphotungstic acid ionic liquid catalyst was synthesized through simple mechanical stirring based on photocatalytic oxidation method at room temperature.The degradation experiment of organic sulfides was carried out in the formic acid hydrogen peroxide oxidation system.The experimental results indicate that the designed photocatalytic oxidation method based on ionic liquid catalyst has achieved excellent performance in the removal of organic sulfides in industrial wastewater,and is expected to be gradually promoted and applied in practical production.
