综述了国内外计算流体力学(Computational Fluid Dynamics,CFD)在膜生物反应器(Membrane Bioreactor,MBR)研究中的应用进展,介绍了与活性污泥模型(Activated sludgemodel,ASM)相结合的ASM—CFD模型在MBR研究中的应用状况.曝气优化,膜组件、膜单元及生物单元结构的优化是目前基于CFD的MBR模拟研究重点.国外CFD模拟研究较早,模拟规模已高达4 800m3/d.与之相比,我国开展MBR的CFD模拟研究起步较晚,目前仍处在小试规模的模拟阶段.ASM— CFD模拟已在常规活性污泥法污水处理研究中得到了成功应用,预期其在MBR的研究、设计与应用中有望成为一个新热点和方向.
