针对海淡水交替港口的火车滚装船压载水处理系统

针对某火车滚装船航线港口水质较差、泥沙较多且每年出现海淡水交替等特殊情况，选择电解式压载水处理装置和可添加高盐度海水的压载水处理系统。采用排除法分析并确认该船压载水处理装置选型和相关压载水处理系统设计修改优化，使该船实现在海水港口或浑浊的淡水港口进行即压即排的压载水作业，为今后可能的后续船或类似船型的压载水处理系统设计提供有价值的参考和借鉴。

Ballast Water Treatment System of Rail Car Carrier in Terms of Marine-Fresh Water Alternating Port

In terms of the special situations of poor water quality,more sediment,and the annual marine-fresh water alternation in the port of a rail car carrier route,the electrolytic ballast water treatment plant and ballast water treatment system which can add the high-salinity marine water are selected.The elimination method is used to analyze and confirm the selection of ballast water treatment plant and the related design modification and optimization of ballast water treatment system in the carrier,so as to make the carrier realize the ballast water operation of discharging while ballasting in the marine water port or turbid fresh water port,which can provide valuable reference and lessons for the design of ballast water treatment system in the future possible subsequent or similar forms.
