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。

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 10~50μm 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 per-formance standard.The removal efficiency of these two technologies on Chlorophyta was higher than that on Bacillariophyta.
