Abstract Five cosmetics wastewater samples were treated by Dissolved Air Flotation (DAF) assisted by coagulation. Different aluminum based coagulants were used: (Al2(SO4)3, Al 1019, Al 3010, Al 3030, Al 3035, PAX 16 and PAX 19). The raw wastewater COD values were in the range 285-2124 mg/l. The efficiency of DAF depended on different coagulants and production profi le of factory. COD removal was varied from 11.1 to 77.7%. The efficiency of coagulants was similar during treatment of particular sample. The best results were obtained with Al2(SO4)3 and for sample 5 - lotions and shampoos production. The wastewater from UV fi lter creams production (sample 4) was resistant to treatment by DAF regardless of used coagulant. HS-SPME-GC-MS analysis can be a confirmation of DAF effectiveness

使用溶气气浮处理化妆品废水

摘要 采用混凝辅助溶气气浮(DAF)处理5份化妆品废水样品。使用了不同的铝基混凝剂：（Al2(SO4)3、Al 1019、Al 3010、Al 3030、Al 3035、PAX 16 和 PAX 19）。未经处理的废水 COD 值在 285-2124 毫克/升的范围内。DAF 的效率取决于不同的混凝剂和工厂的生产情况。COD 去除率从 11.1% 到 77.7% 不等。在特定样品的处理过程中，凝结剂的效率是相似的。使用 Al2(SO4)3 和样品 5 - 乳液和洗发水生产获得了最佳结果。无论使用了何种混凝剂，UV 过滤霜生产废水（样品 4）均能抵抗 DAF 的处理。HS-SPME-GC-MS 分析可以确认 DAF 的有效性
