| 摘 要： | 底泥中多环芳烃（PAHs）的处理方法主要有物化处理和生物处理。物化处理方法有湿式空气氧化、溶剂浸提、热解吸等；生物处理有好氧处理和厌氧处理。物化处理速度快、效果明显，但能耗高、投资大；生物处理方法虽然能耗低，但速度慢、降解率较低。实际运用中宜发展物化和生物的组合工艺。

| Abstract: | The main treatments of Polycyclic Aromatic Hydrocarbons(PAHs) in polluted sediment were described. By comparison physicochemical treatment with biotreatment, an optimal treatment was suggested. Physicochemical treatment contained wet air oxidation, solvent extraction, thermal desorption, and so on. Process of biodegradation of PAHs contained anaerobic and aerobic processes. To reduce the costs of physicochemical process and improve biodegradation speed, combined process was suggested. |
