摘　　要：基于压载水处理问题,提出一种离子膜电解系统.离子膜是一种特殊的阳离子选择性透过膜,电解系统中的阳极和阴极被离子膜分隔.电解后,阳极产物用于压载水处理,阴极产物用于船舶尾气处理.压载水处理实验选取小球藻、亚心形扁藻和海洋原甲藻作为指示生物.实验结果表明,当有效氯质量浓度达5 mg/L时,可以将三种藻类全部杀灭.Ion-exchange membrane electrolysis-based ship＇s ballast water treatment system was proposed.Ion-exchange membrane is a special kind of cationic selective passable membrane,and the electrolytic anode and cathode are isolated by ion-exchange membrane.The products of the electrolytic anode were used for the ballast water treatment and those of the electrolytic cathode were used for the flue gas desulfurization treatment.Three algae species including Chlorella vulgaris,Platymonas subcordiformis and Prorocentrum micans were performed by this system.Results show that all three types of algae can be killed efficiently when the concentration of available chlorine concentration is up to 5 mg/L.
