| 摘 要： | 生物流化床的床层膨胀行为直接与生化反应区的水动力学和效率相关 ,床层膨胀特性是进行合理设计和运行的重要依据。目前流化床设计一般没有考虑生物膜的影响 ,但生物颗粒的流化行为有别于光滑载体 ,因此需要对曳力系数Cd 和膨胀特性方程中的ui 进行必要的修正。在综合分析基础上 ,探讨了优化两相流化床设计和运行的程序和方法

| Abstract: | The expansion of biological fluidized bed has a strong relationship with hydraulic dynamics and efficiency in biochemical reaction zone, bed expansion characteristics are fundamentally important for us to design and run liquid solid biological fluidized bed. Present fluidized bed designs do not consider the effect of biofilm, but the fluidization of bioparticles is different to that of smooth carriers, thus terminal free fall velocity u i in Richardson Zaki equation and drag coefficient C d should be modified. Based on synthetic analysis, the paper presents the procedure and method for optimizing fluidized bed design and operation. |
