两相分配技术通过非水相介质加快低水溶性污染物的气液传质速率，是当前改善疏水性废气生物净化效果的重要突破口之一。然而，非水相介质难以回收，而且污染物从非水相介质到生物相的传质速率偏低，从而限制了该技术的发展与应用。. 本项目拟以硅油基磁性液体（SMF）为非水相介质，以正己烷为模型污染物，以两相分配体系净化疏水性废气，利用磁场作用对SMF进行回收循环利用。探究SMF对生物代谢的影响及其生物吸附诱导效应，解析微生物的界面作用及其引发的SMF特性变化，分析由SMF-界面生物复合体介导的正己烷多相传质行为，阐明微生物在SMF表面的吸、脱附规律，建立正己烷传质-反应动力学模型，揭示SMF与界面生物交互作用的内在机制与废气净化机理，依此强化SMF-界面生物协同作用，实现正己烷废气的高效、稳定净化，为SMF强化生物法净化疏水性VOCs废气奠定基础。

Two-phase partitioning technology, which can accelerate the interphase mass transfer rate of the pollutant with low water solubility in gas-liquid multiphase via non-aqueous phase, becomes the breakthrough in improving biological purification efficiency of hydrophobic waste-gas. However, it is hard to recover the used non-aqueous phase, and the mass transfer rate of pollutant, from non-aqueous phase to microorganisms, is relatively low, hindering the development and the application of this technology. . In this study, silicone oil based magnetic fluid (SMF) and n-hexane are employed as the non-aqueous phase and model pollutant, respectively. Two-phase partitioning system will be applied for the purification of hydrophobic waste-gas, where SMF can be recycled with the assistance of magnetic field. The effect of SMF on biological metabolism and its induction of microorganisms-adherence will be explored. The interface interaction of the microorganisms and the resulting variations of SMF characteristics will be investigated. Multiphase mass transfer behavior of n-hexane mediated by complex of SMF-interfacial microorganisms will be analyzed, and the adsorption and desorption patterns of cells on SMF will be evaluated. Then a mathematic model involving mass transfer and reaction kinetics will be established. Mechanisms of interaction between SMF and interfacial microorganisms as well as waste-gas treatment will be revealed. Based on these results, synergistic effect between SMF and interfacial microorganisms would be enhanced and thus steady purification of n-hexane with high efficiency would be realized, which lays sound foundation for the application of SMF in the enhancement of biopurifying waste-gas containing hydrophobic VOCs.
