Description
Technical field
The utility model relates to a kind of ship ballast water treatment system.
Background technology
Current, ocean environment is just receiving four and is threatening greatly: the invasion of adventive; The discharging of land pollution; To the overfishing of oceanic resources with to the destruction of sea life habitat.Along with the fast development of world shipping cause, the increasing sharply of tonneaux de jauge, annual about 30 ~ 5,000,000,000 tons of ballast water for ship transfers from a harbour to another harbour, the adventive of thereupon bringing into promptly is one of them.
Boats and ships are when handling goods, and the center of gravity of boats and ships and centre of buoyancy for drinking water, balance and the inclination of boats and ships, must be injected seawater constantly changing in ballast tank when underloading; Seawater with ballast tank when heavy duty drains into outboard.The migration of Here it is water ballast, adventive lacks natural enemy in the native country, spreads unchecked wantonly, causes the ecotope equilibrated to destroy.This just must filter the seawater that injects in the water ballast, and the strainer that tradition adopts can filter the foreign material in the water body get off, but the filter core life-time service; Foreign material are deposited in and are prone to influence water quality on the filter core; Cause filter blocks, inefficacy when serious, even if removable cartridge is safeguarded or changed the operation of must cutting off the water supply; Waste time and energy, the professional carries out the maintenance cost height.
From " nineteen eighty-two United Nations Convention on the Law of the Sea ", require various countries to take measures to prevent that alien species from causing ocean environment that great and deleterious variation possibly take place.And in February, 2004 IMO of International Maritime Organizaton passed through " international shipping water ballast and settling are controlled and management contract " (hereinafter to be referred as " water ballast pact "); This pact is defined at least 30 country's signatures that are no less than world's merchant ship tons gross 35% and comes into force after back 12 months, and the tool retrospective.In these pact supplemental provisions " ballast water for ship and settling control and rule ", stipulated D-1 ballast water exchange standard and D-2 water ballast standard of performance,, before D-2 implements, can adopt the D-1 standard according to shipbuilding n. time and clean ballast capacity,
Before execution date, boats and ships can adopt regular D-1 at regular D-2, before ship entry, change the water ballast that the port of departure sucks with the clean sea water at deep-sea, and its water ballast volume turnover rate should at least 95%.The water ballast standard of performance of rule D-2 regulation is that water ballast must pass through processing, when the discharging water ballast, should reach every cubic metre in minimum size be less than 10 more than or equal to survived in the biology of 50 μ m; Minimum size is less than 50 μ m but be less than 10 more than or equal to survived in the biology of 10 μ m in every milliliter; Poisonous vibrio cholerae is less than 1cfu in per 100 milliliters; Per 100 milliliters of colibacilluss are less than 250cfu; With per 100 milliliters in enterococcus bacteria be less than 100cfu.The index of listing in this emission standard has bigger zooplankton and less plant plankton and indicative bacterium, is difficult to reach requirement with a kind of single treatment process.
In " water ballast pact ", the sea appearance Environmental Protection Committee (MEPC) has issued G1, G2 ... to G14 guide, guide rule, be most important with G8, G9 guide rule especially wherein.There is the secondary substance of harm to be commonly referred to as " active substance " if in ballast water treatment system, added chemical or in treating processes, produced to the ocean, then must (G9) carries out feature of risk and describe, analyze and assessment by " using the ballast water treatment system approved programme of active substance " that IMO passed through in 2008.Active substance and preparation are carried out toxicologic tediously long test, prove that these relevant chemical substances do not have acute and chronic toxicity, can not make organism produce sudden change and canceration.Then through the competent authorities of the state to the IMO of International Maritime Organizaton report, special water ballast expert working group examination is arranged, as tentatively through then awarding " Basic Authorization " first.Manufacturers obtains to rectify and improve according to the suggestion of water ballast expert working group behind the Basic Authorization, and then submit applications, as gets permission, and then awards " final approval ".Comprise and be queued in the interior minimum needs of this process 1 ~ 3 year.
There has been final approval just can by MEPC.174 (58) draft resolution " ballast water treatment system approval guide " that passed through in 2008 (G8) carry out model approval test by authority competent authorities's supervision.Manufacturers is carrying out the test of G8 to authority competent authorities's application by circular No. 28 " authority competent authorities is by the guide rules of G8 guide rule to the model approval program of ballast water treatment system " through " test of first portion " back.
Land-based test and onboard test two major parts are carried out in TR.
Will use two kinds of salinity tests in three kinds of salinity during land-based test, the division of these three kinds of salinity is less than 3PSU, greater than 32PSU or 3 ~ 32PSU.The span of two kinds of salinity of being carried out can not be less than 10PSU.Overall consistency is every cubic metre best 106 but is no less than in 105 the individuality in the inflow, and the organism of minimum size more than or equal to 50 μ m should be arranged; In every milliliter best 104 but be no less than in 103 the individuality, minimum size should be arranged less than 50 μ m but more than or equal to the organism of 10 μ m; In density is in every milliliter of at least 104 activated bacterials heterotrophic bacterium to be arranged.Land-based test will be done 10 circulations at least, and each circulation stores 5 days at least, handles the cabin ejecta and should reach above-mentioned emission standard.Will establish undressed contrast cabin simultaneously, the organism that can survive in the ejecta in contrast cabin after 5 days is greater than 10 times of emission standard, otherwise invalidate the test.
Onboard test is that real ship carries out the sea test that water ballast sucks and discharges; At least 3 circulations; MEPC.173 (58) draft resolution " water ballast sampling guide rule " by passing through on October 10th, 2008 (G2) is taken a sample, and the time begins in discharging, centre and ending phase respectively get 3 appearance (totally 91 cubic metre) and analyze.To report to authority competent authorities by MEPC.175 (58) draft resolution " ballast treatment system model approval report data " at last.And to do environmental assessment, comprise corrosion test and assessment, because a lot of chemical can increase corrosion to the ballast tank dividing plate to ballast tank.
The inflow and the emission request of reply water ballast; The treatment process process is roughly divided machinery, physics, chemistry, heating and biological process, and we can say does not have a kind of single technological process can reach safe, practical, economic, effective and these five standards of environment tolerance that IMO proposes fully.Because the scale of construction of water ballast is very big, be hundreds of and even several thousand times of sewage on the ship, as adopting biological process,, almost be difficult to be competent at because of its residence time needs more than the 20h.In like manner, as adopting heating method,, also be difficult to achieve the goal if there is not enough used heat capable of using on the ship.
At present internal and international is being chemical method at the development product majority just, removes big particle with mechanical filter earlier, throws in the chemical sterilization then, for example, and peroxy acetic acid (PAA), high test bleaching powder.Because it is inappropriate carrying a large amount of chemical on the ship, then the equipment of manufacturing chemistry article aboard ship is installed, for example; 1, adopt the sodium chloride salt in the electrolytic seawater to produce Youxiaolin, with free chlorbenside bacterium; Discharging use again during water ballast in the Sulfothiorine with water in residual chlorine; In electrolytic seawater again electrolysis water become hydrogen,, it is explosion-proof to take safety measures.2, adopt electrocatalysis to produce hydroxyl radical free radical OH*, powerful oxidation disinfection, because of its lifetime second level extremely short, can not have influence on the residue in the discharge water, this is that G9 presses evaluating standard.Yet, preserve the problem that mikrobe after 5 days, bacterium can or can not " regrowth " be still worry.3, adopt ozonizer, high pressure ionization pressurized air becomes O3 ozone, produces atomic oxygen [O] sterilization, and the elder generation that has becomes air into pure oxygen through membrane sepn, and again with pure oxygen system ozone, efficient can be higher.Yet ozone can increase the corrosion of water ballast bulkhead, and is simultaneously the same with aforesaid method, must be through the G9 program auditing of MEPC.
To adopting ultraviolet ray (UV) germicidal treatment technology, between physics and chemical method, also the G9 program that will get ahead during beginning, because seawater character may change.Because the manufacturer of doing is many, proves that repeatedly its influence to environment is not so serious, MEPC just thinks in 59 meetings can evade G9.Quartz burner is used for the sterilization of hospital's sterilizing air or tap water more, for the bigger harbour water of turbidity, because ultraviolet transmitance is affected, validity is had query.Can ultraviolet ray be more with suspicion to the killing rate of the mikrobe of big individuality, thereby a kind of special mighty ultraviolet news generation, also can evade G9 to this and it be unclear that.
The physics method has mechanical filter, hydrocyclone, cavity air pocket and rare gas element etc., and purpose all is the particle plant-animal that swim big, that proportion is bigger to be separated get back in the water area of port that sucks water ballast.Do not make residual mikrobe and bacteria resuscitation with the bacteriostatic method then.Need remove to overcome problem of environmental pollution with certain chemical with respect to chemical method, add again simultaneously and make the flagrant method of addition additional load of environment, the physics method is used is the removal method and suppress its decrement method of growing." water ballast pact " passed through as far back as in February, 2004; And just illustrated in writing form with circular 28 " authority competent authorities is by the guide rule of G8 guide rule to the model approval program of ballast water treatment system " on October 5th, 2010: ballast water treatment system will be done additional test by the G9 program as with active substance; As without that of active substance as long as do approval by the G8 guide rule.
Mostly the ballast water treatment system of exploitation is chemical method before this, relatively complicated, has the risk of recontaminate, and boats and ships, crewman and the reviewer that goes on board are brought potential harm.For this reason, need to research and develop the requirement that a kind of novel ballast water treatment system can reach " water ballast pact " and each item guide rule, guide and standard, again can be safe, practical, energy-conservation, efficient and innoxious.
