  • 摘要: 孔径是微孔曝气产品最重要的参数之一，研究孔径对微孔曝气氧传质的影响对于提高微孔曝气器充氧性能有重要意义。本研究在1.5 m水深条件下对不同大小孔径的钟罩型塑料微孔曝气器充氧性能进行评价。结果发现，在实验条件下，微孔曝气器的阻力损失RL、标准氧总转移系数KLas、标准氧转移速率SOTR，标准氧转移效率SOTE及理论动力效率E随孔径增大而显著减小。
    Abstract: Pore diameter is one of the most important parameters for fine bubble diffusers, and it is necessary for improving oxygenation performance to study impacts of pore diameter on oxygen mass transfer. We assessed the impacts through a pilot test using the plastic bell-type fine bubble diffusers at the 1.5 m water depth. The results showed that RL, KLas, SOTR, SOTE and E decreased significantly when the pore diameter increased.
