| 摘 要： | 分析光催化和纯紫外工艺对控制处理压载水中10～50μm藻类的影响,比较了压载水中10～50μm藻类的去除率、种类变化、绿藻和硅藻去除率以及硅藻种类数的变化,结果显示光催化工艺对10～50μm藻类的去除效果要好于纯紫外工艺。两种工艺对10～50μm藻类的即时去除率均可以达到96.0%以上,压载数日后排放则效果更佳。研究发现两种工艺对硅藻的处理效果不如绿藻。并且压载水盐度会影响压载水处理工艺的效果。

| Abstract: | The removal efficiency of photocatalysis technology and pure UV technology on 10 ～ 50 μm organisms in ballast water was compared. Photocatalysis technology showed higher removal efficiency on the total organisms,the number of species,Chlorophyta and Bacillariophyta than pure UV technology. The removal efficiencies on all the 10 ～ 50 μm organisms using photocatalysis technology and pure UV technology were more than 98. 0% immediately,and the density of organisms in the discharge water met the ballast water performance standard. The removal efficiency of these two technologies on Chlorophyta was higher than that on Bacillariophyta. |
