Description
[technical field]
The present invention relates to a kind of neutralizing device and neutralization method of ship ballast water, particularly a kind of being used for neutralizes and the neutralizing device and the neutralization method of germicidal treatment to the remaining toxic substance that ship ballast water generates.
[background technology]
Usually; Water ballast (Ballast Water) is meant when boats and ships navigate by water under the unloading or the less state of freighting; In order to prevent the boats and ships overbalance, the fresh water or the seawater that are used to adjust ship buoyance that in the water ballast storage tank of bottom of ship both sides, pour into.
In above-mentioned ship ballast water, there are a lot of fresh water and seawater mushroom and planktonic organism, when directly being discharged into other marine sites to these water if do not handle, ship ballast water destroys the eubiosis with the severe contamination ocean environment.
To these situation; The U.S. has formulated from 1996 about country's intrusion bacterial classification and has prevented bill, is defined as the invasion bacterial classification to external bacterial classification, has carried out mandatory ship ballast water management and control system; In addition; Relevant quarantine act has also been revised by Australia, is defined as the Quarantine Objects of inward cargo, the detection of directly quarantining to ship ballast water.
In addition, in February, the 2004, (IMO of International Maritime Organizaton; International Maritime Organization) formulated international convention,, required on boats and ships, to be provided with ship ballast water germicidal treatment facility from 2009; When ship was violated this regulation, the harbour can forbid that turn round berths.
For this reason, various countries are handling the technical research of ship ballast water aspect recently, and wherein, representational research and development technology is for utilizing ozone (Ozone:O
3) or electrolysis realize ship ballast water sterilization and purification; Aspect ozonize, the technical scheme of the ship ballast water treatment facility aspect of No. the 16091st, the Korean Patent of application in 2007 and No. 17653 and No. 19305 has obtained 10-769834 number, 10-775238 number, 10-802889 patent.
But, utilize original ship ballast water treatment facility of above-mentioned ozone sterilization technology in the germicidal treatment process, can generate the toxic substance that is similar to residual oxide (TRO, Total Residual Oxidants); In general, but these toxic substances natural decomposition after 1-5 days, therefore; For blue-water shipping; Such scheme is a feasible program, but short distance navigation or toxic substance be not when decomposing, and the ship ballast water of discharging will become source of pollution.
That is to say, during desire discharging ship ballast water, if in the ship ballast water of germicidal treatment, leave toxic substance,, can not discharge as early as possible, thereby have to postpone shipping because will wait until its natural decomposition.In addition, according to generating the geographic sea state of ship ballast water, if the long-time placement of toxic substance still can't be decomposed, also above-mentioned situation can appear.
