为探讨贝、藻偶合方式对集约化养殖尾水的净化作用,研究分析了香港牡蛎 (Crassostrea hongkongensis) 和钝顶螺旋藻 (Spirulina platensis) 耦合对富含氮 (N)、磷 (P) 营养盐的生物絮团养殖尾水的处理效果。实验共设置5组,小规格组 (S)、中规格组 (M) 和大规格组 (L) 添加的牡蛎个体均质量分别为 (50.99±7.01)、(100.25±8.87) 和 (148.81±15.61) g,阴性对照组 (NC) 只添加螺旋藻,空白对照组 (BC) 不添加牡蛎和螺旋藻,实验组中螺旋藻密度约为 8×105 个·mL−1,牡蛎生物量为3 kg·m−3。记录牡蛎的成活率及生长情况,显微镜计数螺旋藻密度,测定水体氨氮 (Crassostrea hongkongensis) and microalgae (Spirulina platensis) on tailwater treatment of biological flocs which are rich in nitrogen and phosphorus nutrients. A total of five groups were set up. The average mass of oysters added to the small (S), medium (M) and large (L) size groups was (50.99±7.01), (100.25±8.87) and (148.81±15.61) g, respectively. The negative control group (NC) was only added with spirulina, and the blank control group (BC) was not added with oysters and spirulina. The density of spirulina was about 8×105 cell·mL−1 and oyster biomass was 3 kg·m−3. The survival rate and growth of oysters were recorded, and the cell density of spirulina in water was counted under a microscope. The concentrations of 相似文献
