Embodiment Construction

[0015] The present invention is described in further detail below in conjunction with accompanying drawing:

[0016] As shown in Figure 1, a kind of device of the new method of processing ship's ballast water of the present invention is made up of high voltage pulse power supply 1, discharge vessel 2, anode electrode 5, cathode electrode 6, electrode support 7, electrode support 8 and flange 9 , Flange 10 components. The discharge vessel 2 is placed horizontally or vertically, and it is provided with a water inlet 3 and a water outlet 4, which are used for the flow channel of the ship's ballast water; the anode electrode 5 and the cathode electrode 6 are inserted into the discharge vessel 2, and the axes of the two electrodes are in line with the discharge vessel The axis of 2 is vertical and suspended in the ship's ballast water. The anode electrode 5 and the cathode electrode 6 are respectively fixed with the electrode bracket 7 and the electrode bracket 8, and the two elec...

Abstract

A method for treating ship ballast water and its treating device are disclosed. The process is carried out by immersing two discharge electrodes into ship ballast water, applying high-voltage pulse voltage between two electrodes, producing liquid-phase discharge to generate shock wave, ultraviolet ray and various active free radicals and sterilizing mono-cell, bacterium, protozoon and other harmful living things. It utilizes shock-wave pressure and oxidation effect, ultraviolet sterilizing effect and accelerating chemical reaction, and hydroxyl-free radical, active oxy-bromide species and other free-radical high oxidation processes, the treating device consists of high-voltage power supply, discharge electrode and discharge container. It's cheap and simple and has no chemical dispensing residue. It can be used for ship ballast water transfer and shore-base treatment.

Description

technical field [0001] The invention relates to the technical field of liquid-phase discharge plasma and biological applications, in particular to a treatment method and device for killing various harmful organisms during the transportation of ship ballast water. Background technique [0002] Ballast water is the seawater from the offshore port carried by the ship, which will be discharged into the sea area of ​​the destination country when it reaches the shore. Ballast water is the most important way to cause the spread of harmful organisms in the ocean. There are 3,000 to 4,000 species of organisms carried in ballast water around the world every day. So far, around 500 biological species have been identified globally as being transmitted by ship ballast water. These alien marine organisms not only threaten the ecological security of coastal areas, but also bring huge losses to the global economy. [0003] At present, the treatment methods of ballast water mainly include ...
