Embodiment Construction

[0029] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0030] combine figure 1 A flow chart of the method is described in detail. The ballast water passes through the stainless steel filter in turn to remove large suspended pollutants and suspended algae in the water, and then reaches the microporous filter for filtration and enters the discharge reaction device. The residence time of the ballast water in the reaction device is 0.1 to 2 hours. The ballast water after discharge discharge treatment enters the ballast tank through the filter at the outlet of the discharge device.

[0031] combine figure 2 and image 3 . The ballast water sequentially passes through the water inlet 1, passes through the valve 2, reaches the stainless steel filter 3, removes large suspended pollutants and suspended algae in the water, and then reaches the microporous filter 4 for filtration, the filter hole is 20-50 microns, and ent...

Abstract

The invention provides a ship ballast water treatment method and a discharge reactor. Ballast water firstly reaches a stainless steel filter screen through a water inlet pipeline, and is filtered by a microporous filter to enter the discharge reactor with particle catalyst; pulse high voltage is applied between a high voltage electrode and a ground electrode of the discharge reactor to generate high voltage pulse discharge; oxygen-containing gas is communicated with the discharge reactor during discharging process, the ballast water treated by the discharge reactor enters a ballast cabin via a filter arranged at the outlet of the discharge reactor. The invention enables the plasma generated by discharging to directly and rapidly react with exotic causative agent and harmful aquatic matter in ballast water, and kills and inactivates the exotic causative agent and harmful aquatic matter under a series of online generated physical and chemical efficacies, and accordingly reduces the pollution of the ballast water to the ocean.

Description

technical field [0001] The invention relates to a water treatment method, in particular to a treatment method for ship ballast water. The invention also relates to a treatment device for ship ballast water. Background technique [0002] In order to sail safely at sea, a certain amount of ballast must be loaded according to the loading state and its own performance at that time, and its function is to ensure that the ship has good stability and buoyancy. Since the 1880s, ships have generally used water as ballast, which is called ship ballast water. If a ship loads ballast water containing harmful aquatic organisms or pathogens and discharges the ballast water into the waters of the port state, it will pose a threat to the local ecological environment, economy and human health, and these threats are long-term . The encroachment of marine species on the marine environment caused by ships' ballast water has been recognized by the Global Environment Fund as one of the four ma...
