摘　　要：以小球藻Chlorella pyrenoidsa F-9和C.vulgaris HYS-2为材料,研究小球藻在鱼糜加工废水中的生长速率、脂类积累规律和对氮磷营养的消除效果。结果表明,2种小球藻在鱼糜加工废水中快速生长,最高生物量达到0.293 g/L和0.276 g/L,分别是f/2对照培养基的2.4和1.6倍。小球藻HYS-2在鱼糜加工废水中油脂百分含量最高达到36.22%,为对照培养基的1.27倍,小球藻F-9在鱼糜加工废水中的油脂含量达到17.89%,为f/2培养基中的0.89倍。培养15 d后,2种小球藻对鱼糜加工废水中氮磷去除率均达90%以上。以上研究表明,用未经任何化学处理的鱼糜加工废水养殖小球藻在生长速率上远远大于f/2培养基,说明其具有较好地发展潜力,可以实现微藻的低成本养殖。The growth,lipid content,and the removal effects of nitrogen and phosphorus of Chlorella pyrenoidsa F- 9 and C. vulgaris HYS- 2 grown in surimi wastewater were studied. Results showed both Chlorella could grow rapidly in the surimi processing wastewater and the highest biomass were 0. 293 g / L and 0. 276 g / L respectively,2. 4 and 1. 6 fold higher than that of the control group of f /2 medium. The highest total lipid contents of HYS- 2 and F- 9 in surimi processing wastewater were 36. 22% and 17. 89%,respectively,1. 27 times and 0. 89 times of that in f /2 medium,correspordingly. After 15 days＇ culture,the nitrogen and phosphorus removal efficiencies of two species of Chlorella were more than 90%. Chlorella cultured in surimi processing wastewater showed comprehensive growth rate which was far greater than that in f /2 medium. It indicated that it has good potential development,and could make the low cost of microalgae culture.
