| 摘 要： | 应用粒子图像测速(PIV)技术测试膜面附近的气液两相流动力学特性,在6种不同曝气强度条件下,测试得到膜面附近的液相流场数据,并计算得到膜面传质系数、浓差极化边界层厚度以及膜面切向应力等膜面传质特性参数。结果表明,曝气强度和液相速度对膜面传质特性的影响较大,在一定范围内增加曝气强度可以使得膜面传质特性加强。本文的研究结果为膜生物反应器系统的优化设计提供了研究经验和实验数据。

| Abstract: | Particle image velocimetry (PIV) technique was used to test the gas-liquid two-phase flow field dynamics above the membrane approach in six different aeration intensity conditions. The liquid flow field above the membrane approach was tested, and the membrane surface mass transfer, thickness of concentration polarization boundary layer, shear stress and some other mass transfer parameters of membrane surface were calculated. The conclusion shows that the aeration intensity and liquid phase velocimetry strongly influence the characteristic of membrane surface mass transfer, and the aeration intensity increased in a certain range can make the membrane surface mass transfer characteristic strengthen. The paper provides experimental data and research experience for optimization design of membrane bio-reactor. |
