摘要
试验中将过滤作为一级处理,处理海水中较大的固体悬浮物和微生物;将紫外线作为二级处理,处理过滤后海水中残存的较小的微生物和细菌。经试验得出过滤与紫外线技术联合处理压载水平均灭活率可达98%以上,且设备结构简单,易于维护保养,投资维护费用低,处理成本约是传统方法的1/5。
Filtration works as the first step pretreatment to separate solid particles,of which the densities are greater than that of sea water,and microorganism,ultraviolet radiation works as the second step treatment to disinfect residual microorganism and bacteria.This combined treatment method is expected to get a killing rate of above 98%.Its relevant equipment is easy to be maintained and the treatment cost is only the cost of 20% by traditional methods.
