摘要

为考察连续泡沫分离法采收微藻细胞的可行性

在一种斜臂泡沫分离装置上

以螺旋藻为模型藻种

较为详细地研究了载气流率、藻液进料流率、浓度、pH值、离子强度、乙醇浓度、进料位置、泡沫段与液相段高度之比等因素对泡载采收性能的影响。结果表明 :在载气流率、藻液进料流率或藻液浓度较低时采收性能良好 ;当 pH值为 11、离子强度为 1 3× 10 4 μs·cm-1、乙醇浓度为 3%(体积 )时泡载收率可达 2 5 %～ 45 %;采用泡沫相段进料有利于提高泡载采收性能。提出的连续泡载采收动力学模型与实验值拟合较好 .

Abstract

Experiments were carried out on continuous foam separation of Spirulina cells by use of a novel and effective bubble column

namely the incline-armed bubble column. The influences of the operation parameters such as gas flow rate

feed rate

feed concentration

solution pH value

ionic strength

ethanol concentration

feed position etc.on the enrichment ratio and recovery of Spirulina cells were investigated in detail.On the basis of the analysis of separation process

a mathematical macro-model for continuous adsorptive bubble separation was established.
