| 摘 要： | 为了分析螺旋升流式反应器去除COD及N、P效果好的原因,利用计算流体力学(CFD)商用软件PHOENICS对螺旋升流式反应器厌氧段的流态特征进行了模拟研究.研究结果表明:螺旋升流式反应器内流体流态为以螺旋方式上升的推流流态和完全混合流态,其中推流流态约占65%.反应器兼有PFR和CSTR 反应器的特点,使其具有较好的处理能力.

| Abstract: | In order to analyze the reason why the Spiral Up-flow Reactor system has excellent removal effect of COD, N and P, the authors use PHOENICS, a computational fluid dynamics program, to investigate the hydraulic characteristics and flow model of the anaerobic part of Spiral uP-flow reactor. The result shows that the fluid in the reactor unit flowed upward by the spiral way, and that flow pattern was combined by plug flow and complete-mix flow, and that the percentage of plug flow was about sixty-five percent. Spiral Up-flow Reactor units the Characteristics of PFR and CSTR, which makes it work well. |
