中文摘要:

为降低钝顶螺旋藻培养和采收成本，利用膜光生物反应器（MPBR）进行钝顶螺旋藻培养和预采收的条件研究实验。实验结果表明：当生物量达到1.8 g/L时可进行微藻采收；初始藻液质量浓度为1.828 g/L时，MPBR中最大体积浓缩系数为2，最佳稀释率为0.08 d^-1，藻产品质量浓度可达3.319 g/L；获得1 g微藻生物量，MPBR中可节约水、氮、磷的量分别为0.301 L、0.248 g、0.053 g。与传统光生物反应器（PBR）相比，MPBR能够降低微藻培养和采收的成本。

英文摘要:

In order to reduce costs in theSpirulina platensisculture and harvest process，a membrane photobioreactor（MPBR） was used for Spirulina platensis cultivation and pre-harvsting. The results showed when the biomass attained about 1.8 g/L，microalgae could be harvested. And when the initial algal biomass concentration was 1.828 g/L，the maximum volume concentration factor was 2 in MPBR. The optimum dilution rate was 0.08 d^-1and the concentration of biomass product was up to 3.319 g/L during the cultivation in MPBR. The amount of water saving，nitrogen saving and phosphorus saving were 0.301 L，0.248 g and 0.053 g respectively when per 1 g biomass product was harvested in MPBR. The costs of microalgae cultivation and harvesting could be reduced in MPBR compared with the traditional photobioreactor（PBR）.
