采用自制的光生物反应器,研究了不同条件对小球藻脱除空气中CO2效果的影响.光生物反应器为圆柱形有机玻璃容器,底面积0.015 4m2,高0.2 m,容积为3 L,反应器内小球藻藻体干重约为7.2 g.实验结果表明,用小球藻来固定CO2不仅能脱除通入气体中的CO2,而且可以促进小球藻生长.通入气体的流量和CO2浓度对CO2的脱除率有很大影响.在适宜的实验条件下(通入气体流速为0.6 L/min、CO2浓度约1%、温度25～30℃、光强3 500lux、pH 9.5～8.5),入口气体中CO2约有50%被脱除,该光生物反应器脱除CO2的能力约为0.118g/(L·h).可见利用小球藻光生物反应器固定CO2具有较好的脱除效果,值得进一步研究.
