| 摘 要： | 以我国典型淡水水华藻种铜绿微囊藻(Microcystis aeruginosa905)为研究对象,采用推流式低压紫外灯反应器研究在动态条件下Ultraviolet-C(UV-C)辐照对蓝藻生长抑制作用的效果.对数培养期的蓝藻液流经反应器进行UV-C辐照处理,其后正常培养,在培养期2 h、1 d、3 d、5 d、7 d、9 d分别取样,通过研究级倒置荧光显微镜在荧光视野下进行细胞计数.结果表明,辐照处理未引起铜绿微囊藻细胞的大量破裂死亡,36~115 mW.s.cm-2剂量范围的UV-C辐照能在9 d内有效抑制2.6×105~2.7×105cells.mL-1的铜绿微囊藻细胞密度增长,31~50 mW.s.cm-2剂量范围的UV-C辐照能在9d内有效抑制9.0×105~1.15×106cells.mL-1的铜绿微囊藻细胞密度增长.

| Abstract: | A plug-flow UV-C reactor equipped with low pressure UV lamp was utilized to study the suppression effect after UV-C irradiation under the dynamic conditions on Microcystis aeruginosa,a typical cyanobacterium in algae blooms in China.The culture fluid of Microcystis aeruginosa was exposed to UV-C irradiation when pumped through the reactor.After that,the fluid was incubated under the normal culture condition,and sampled at 2 h,1 d,3 d,5 d,7 d,9 d for determination of cell density using the inverted system fl... |
