摘要: 针对防治海洋外来生物入侵性传播这一国家重大需求,利用大气压强电场放电的极端物理手段高效制备羟基自由基这一技术治理船舶压载水.实船试验在大连港“育龙号”上进行,羟基自由基压载水处理系统的处理量为250 m3/h,试验从生物有效性、相关化学物质分析以及水质指标变化3个方面对系统性能进行考察.试验结果表明,处理后压载水生物有效性可以达到国际海事组织(IMO)D2标准;产生的相关化学物质以三溴甲烷浓度最高,其生成量为8814 μg/L;水质指标中溶解有机碳(DOC)、颗粒有机碳(POC)和总悬浮颗粒物(TSS)有明显变化,其变化规律是DOC随着时间的增加而增加,POC随着时间的增加而降低,TSS随时间增加而降低.该设备为在航治理船舶压载水提供了成功的范例,为开拓全球航运市场提供了技术支撑.
