液相放电处理海水中卤虫的研究

Study of Eradicating Anemia with High Voltage Pulsed Discharge in Liquid

运用液相高压脉冲技术,采用自行设计的板-孔-板反应器,处理压载水中典型的浮游动物——卤虫.对卤虫的虫卵、幼虫和成虫3个成长期进行研究,通过改变峰值电压、脉冲频率和处理时间这些参数来考查其对卤虫处理效果的影响.结果表明:随着峰值电压、脉冲频率和处理时间的增加,卤虫幼虫和成虫的杀灭率增加,虫卵的孵化率降低;在适当的放电参数下,卤虫成虫和幼虫的杀灭率均可以达到100%;较低电压对卤虫卵的孵化率没有影响,在电压高于34 kV时,虫卵的孵化率才会降低,然而,经过放电处理后虫卵的孵化时间会缩短.

High voltage pulsed discharge directly in water and the board-hole-board reactor were used to treat Anemia in ballast water.The growth periods（eggs,larvae,adult） for Anemia were studied by changing the peak voltage,pulse frequency and treatment time these parameters to examine the kill effect.The results showed that as the increase of peak voltage,pulse frequency and treatment time,kill rates of larvae and adult were increasing and hatch rate of eggs was decreasing.In the appropriate discharge parameters,the kill rate on larvae and adult could reach 100%.There was no influence on hatch rate of eggs at low voltage.When the voltage was over 34 kV,hatch rate of eggs began to decreasing.However,the brooding time of eggs would curtail after treatment.
