【摘要】 为有效防止压载水外来生物的入侵传播,提出了水中高压脉冲放电技术处理压载水.该技术采用超高压快速上升的脉冲电压和板-孔-板式反应器在液体中产生强烈放电,解决了电极损耗和高电导率时的高耗能问题.考察了高压脉冲放电对不同藻类的处理效果,确定并比较了对应的脉冲参数.结果表明:放电对藻的杀灭率可达100%.在所选的海藻中,绿藻门的藻类是最难处理的,硅藻其次,金藻是最易处理的藻类.更多还原

【Abstract】 To prevent the invasive spread of nonindigenous organism invasion from ballast water effectively,high voltage pulsed discharge directly in water was proposed to treat ballast water. The pulsed voltage(with ultra-high voltage and rapid rising time) and plate - hole - plate reactor were used to create strong discharge in liquid.The problems of electrode corrosion and high energy consumption in high electrical conductivity water during the period of discharge could be solved.The killing effects on different algae were studied,and the corresponding discharge parameters were ascertained and compared.The results showed that the killing rate on algae via discharge treatment can reach 100%.In selected species,chlorophyta is the most difficult to treat,the diatom is the second,and chrysophyte is the easiest.更多还原
