摘要:
在中试规模的混合生长式膜生物反应器（HG-MBR）中,采用导流板对膜区和填料区的隔离网进行了优化研究，通过清水试验分析了导流板面积和位置对反应器流体力学特性的影响。结果表明，使用导流板可以改善反应器的流体力学特性，减小隔离网对填料流动的负面效应，降低驱动填料流化所需的曝气量，促进填料在反应器内的循环流动，从而达到节能降耗的目的。优化运行结果表明，膜区和填料区之间的隔离网在上部采用导流板式封闭设计（面积约为0.71 m2），当填料填充率为50%时，驱动填料流动所需的曝气量可减少15%以上，节能效果明显。
Abstract:
The study was carried out for optimizing the separation mesh between the membrane area and the carrier area by using a baffle in a hybrid growth membrane bioreactor (HGMBR). The effects of the area and the location of the baffle on the hydrodynamic characteristics of the reactor were investigated by clean water experiment. It was found that the use of a baffle could improve the hydrodynamic characteristics of the reactor, mitigate the negative impact of the separation mesh on the mobility of the carriers, reduce the aeration rate required for driving the carriers, enhance the recirculation of the carriers in the reactor, and therefore reduce the energy consumption. The optimized operation results showed, when the closed design of a baffle (an area of 0.71 m2) on the upper part of the separation mesh between the membrane area and the carrier area was adopted and the filling ratio was 50%, obvious energy saving effects were achieved as aeration rate driving for the moving of the carriers was reduced more than 15%.
