摘要： 通过对盐藻细胞的浓缩倍数和采收率的测定，考察了藻液pH值、气体流速(vg)、藻细胞初始浓度(C0)对盐藻细胞的泡载分离采收性能的影响，优化了盐藻细胞泡载分离采收条件. 结果表明：在vg为60 ml/min，C0为2.58?105 个/ml，pH值为7.5的条件下，盐藻细胞泡载分离的采收率达90%~94%，浓缩倍数达30~34. 泡载分离是分离浓缩盐藻细胞的一种简便、高效的方法.

Abstract: Taking Spirulina cells as the model, experiments were carried out on a novel and effective slant-armed bubble column to investigate the feasibility of foam flotation of micro-algal cells. The effects of a number of operation parameters such as carrying-gas flow rate, solution pH value, concentrations of ethanol and Tween 20 on the enrichment ratio and recovery of cells were examined and some useful data were presented.

Key words: foam flotation, Spirulina, adsorptive-bubble separation
