摘　　要：为了提高基于毛细作用微藻固定化复合载体培养系统中小球藻Chlorella vulgaris FACHB-1072的生物质产率,采用响应曲面分析法(Response Surface Methodology,RSM)中的中心组合算法(Central Composite Design,CCD)设计实验参数.结果表明,响应面建立的微藻生物质产率的二次回归方程的拟合度良好,模型相关系数都达到97%以上.最佳的生物质产率组合为:CO2流速0.03 L/min、培养周期127.63 h、光稀释面积比率RAD1.32.在该条件下普通小球藻生物质产率达到34.81 g/m^2/day,与理论预测值较好吻合.同时,总氮(Total Nitrogen,TN)去除率达95.64%,起到了较好的污水治理效果.The aim of this research is to improve the biomass productivity of chlorella vulgaris FACHB-1072 biomass in the Capillary Action Microalgae Attached Cultivate System.Experiments were performed using the Central Composite Design(CCD)parameters in Response Surface Methodology(RSM).Results showed that the quadratic regression equation of microbial biomass yield,the correlation coefficient of the model was more than 97%.The optimum combination of productivity conditions are:CO2 flow rate 0.04 L/min,Culture Period 124.86 h,light dilution area ratio(RAD)of 1.33.Under this condition,the productivity of C.vulgaris reached 34.81 g/m^2/day.At the same time,the Total Nitrogen(TN)removal rate reached 95.64%,which played a very good sewage treatment effect.
