脈沖電弧液電放電壓載水處理效果的研究
[Abstract]:Ballast water is an important guarantee for the safe navigation of modern ships, and the harmful organisms and pathogens carried in ballast water will destroy the marine environment, endanger human health and cause related economic losses. The damage of ship ballast water to the marine environment has attracted the attention of the International Maritime Organization (IMO) and the countries all over the world. At present, there is not an effective way to deal with comprehensive safety, efficiency, cost, environment and other factors. In accordance with the requirements of the D-2 standard of the International Convention on the Control and Management of Ballast Water and sediments in ships, the influence factors of pulsed arc liquid electric discharge ballast water treatment, including the materials of discharge electrodes, the diameter and the gap distance, are studied experimentally in this paper. The effect of water sample, water flow rate and so on germicidal effect. The effects of pulsed arc discharge on the treatment of viable organisms in ballast water were studied. Through experiments, it is determined that under certain pulse power supply conditions, there is an optimum parameter to achieve the optimal effect of pulse arc liquid electric discharge ballast water treatment, pulse arc liquid electric discharge to Escherichia coli and different types, Algae of all sizes have better killing effect and will not regenerate algae, and the experimental reaction quantity and the smaller velocity change have little influence on the effect of electric discharge of pulsed arc liquid to kill algae, which provides the basis for shore-based and full-ship test. It is also prepared for the research and development of pulse arc liquid electric discharge ballast water treatment system.
