摘要:
为定量化研究水动力对鄱阳湖撮箕湖水体中蓝藻生长的影响,该文采用灭菌撮箕湖原水在光照培养箱中控温、控光的无菌条件下,使用自制有机玻璃环形槽进行水体流速控制试验.研究结果表明:在撮箕湖原水培养液中微囊藻的生长随水流速度的增加呈先增加后降低的变化趋势,当水流速度为45 cm·s-1时最有利于微囊藻的生长,微囊藻最大比生长速率、最大藻密度也呈相似的变化规律.在对照组中微囊藻最大比生长速率和最大藻密度分别为0.32 d-1和1.480×106 cells·mL-1; 在实验组中微囊藻最大比生长速率和最大藻密度最高分别为0.43 d-1和2.329×106 cells·mL-1.水流对微囊藻生长促进作用较低,水体富营养化增加水流将进一步提高微囊藻生长,增加蓝藻水华风险.
Abstract:
In order to quantify the effect of hydrodynamic on the growth of cyanobacteria in the water body of Zuoji lake,the flow rate control test is carried out in a self-made plexiglass annular tank under the sterile condition of temperature and light control in a light incubator.The results show that the growth of Microcystis aeruginosa in the raw water of Zuoji Lake first increases and then decreases with the increase of flow velocity.The flow velocity is 45 cm·s-1,which is the most suitable for the growth of Microcystis aeruginosa.The maximum specific growth rate and maximum algae density of Microcystis aeruginosa also show a similar change law.In the control group,the maximum specific growth rate and maximum algal density of algae are 0.32 d-1 and 1.480×106 cells·mL-1,respectively.The maximum specific growth rate and maximum algae density of Microcystis aeruginosa in the experimental group are the highest,which are 0.43 d-1 and 2.329×106 cells·mL-1,respectively.At present,the effect of water flow on the growth of Microcystis aeruginosa is low,and the increase of water eutrophication will further improve the growth of algae and increase the risk of water bloom.
