Study Of The Characteristics And Application For The High Voltage Pulse Discharge Reactor In Gas-liquid Interface

As maritime transportation developing rapidly, the problem that seawater which contains bacteria and viruses in the water ballast tanks has caused worldwide concern, as the quantity of water in ballast tanks is rising year after year. The technology which can control this issue effectively is one of the most-watched problems in the world. The technology of High Voltage Pulse Discharge is one of the newest techniques for water treatment, which contains High-energy Electron Irradiation, Photochemical Oxidation and Chemical Oxidation, while the additional temperature, pressure or illuminant are unnecessary for this treatment, thus this technique has its application prospect widely.This present study designs a gas-liquid high voltage pulsed discharge reactor, and analysis the characteristics of intake in discharge process, product of discharge and emission spectrum. Then the study discuss different discharge parameters (peak voltage, pulse frequency, processing time) by using gas-liquid high voltage pulsed discharge reactor via kill the typical plankton Anemia. At the same time, the study has the elementary discussion of the inactivate mechanism by compare the differences of Anemia between before and after discharge by using microscope. The conclusion is the effect of discharge is much better with intake increase by impulse voltage increase, distance of catwhisker to liquid level decrease and liquid electric conductivity decrease. The concentration of discharge product H2O2 and O3 increases as well, as impulse voltage increase, pulse frequency increase, discharge time expand, original electric conductivity increase, pH value increase. According to the concentration of H2O2 and O3, the put-in gases have an order as Oxygen> Air> Argon> Nitrogen. As peak voltage increases, pulse frequency increases, treatment time expands, the fraction surviving of Anemia are all decrease, therefore the effect of treatment is better. It is found that the structure of Anemia after treatment has changed compare with the original micro-structure, which further proved discharge process produce cell destroyed, then cause death.
