摘　　要：目的面向空间微藻培养需求,探究基于中空纤维膜技术进行微藻培养的气体交换性能和影响规律。方法开展不同供气流量、膜面积和液体流速等参数对中空纤维膜组件CO_(2)固定效率和固定速率的影响的研究,并通过拟合公式比较不同参数条件的气体交换性能。结果供气流量和膜面积对组件气体交换性能有显著影响,随着供气流量的增加,CO_(2)固定速率呈现先上升后平稳的趋势,CO_(2)固定效率呈现持续下降的趋势;随着膜面积增加,CO_(2)固定速率和固定效率都显著上升;液体流速对组件气体交换性能无显著影响。CO_(2)固定速率在0.3 m^(2)膜面积、2.0 L/min供气流量时最高,为168.24 mg/(L·h)。结论采用中空纤维膜技术能解决藻液与大气间进行气体交换所面临的两相流管理难题,实现较好的气体交换效果,可以为空间微藻光生物反应器气体交换组件的设计提供参考。Objective In this study,the gas exchange performance and impact patterns of microalgae culture based on hollow fiber membrane technology were investigated for the culture of space microalgae.Methods The effects of parameters and conditions such as gas flow rate,membrane area and liquid flow rate on the CO_(2)fixation efficiency and fixation rate of hollow fiber membrane modules were studied,and the gas exchange performance of different parameters were compared by fitting formula.Results The gas flow rate and membrane area have a significant effect on the gas exchange performance of the module.With the increase of gas flow rate,the fixation rate of CO_(2)increases at first and then stabilizes,and the fixation efficiency of CO_(2)shows a continuous downward trend;with the increase of membrane area,the fixation rate and fixation efficiency of CO_(2)increase significantly,while the liquid flow rate has no significant effect on the gas exchange performance of the module.The highest CO_(2)fixation rate was 168.24 mg/(L·h)when the membrane area was 0.3m^(2)and the gas flow rate was 2.0 L/min.Conclusion The use of hollow fiber membrane technology can solve the problem of two-phase flow management in the gas exchange between algae culture and atmosphere,which has a better effect on gas exchange,and can provide reference for the design of gas exchange module of space microalgae photobioreactor.
