Description
Technical field
The utility model relates to environment protection and hull protection technical field, especially a kind of ship ballast water treatment system.
Background technology
Water ballast can be guaranteed the correct center of gravity and the necessary balance and the stability of boats and ships.At present, nearly 10,000,000,000 tons of the water ballast that annual global boats and ships carry, have at least every day 7000 organisms etc. with the ballast water for ship oceangoing voyage to alien land.Species are invaded mutually, have aggravated the deterioration of marine ecology chain and environment.The ballast water yield that 190,000 tons of freighters of a load-carrying carry has surpassed 80,000 tons, the animals and plants that swim in the water ballast average every cubic metre up to 1.1 hundred million, the biology that every day, carried in water ballast in the whole world has surpassed 3000 kinds, and 300,000,000 of survival dinoflagellate packings are arranged in a water ballast tank.Portion investigation from Hong Kong shows: found 81 kinds of meiofauna and protozoons that the locality does not have in five ship water ballast water samples that selective examination is navigated.
Though severe environment such as that most of hydrobiont can't be stood is unglazed in the ballast tank, anoxic, iron content height are and dead on the road, minority " powerhouse " but can arrive the unballast waters smoothly, and bases oneself upon breeding in the locality, becomes the invader.The invasion of this adventive can cause the destruction of harbour state aquatic ecological, brings loss to local economy.Ballast water for ship also may carry the pathogenic agent with strict region epidemic characteristic, causes epiphytotics propagation, threatens the harbour state public's health.International Maritime Organizaton (International MaritimeOrganization, be called for short IMO) 2004 has formulated water ballast and settling management contract at the water ballast pollution present situation, requires various countries' boats and ships that ballast water treatment plant was installed after 2010 successively.
It is the focal issue of a global concern that IMO points out to administer the invasion of water ballast harmful organism, does not advocate different regions and adopts different improvement systems.Basic demand is: aboard ship handle; Cost is cheap, and equipment is small and exquisite, is convenient to operation; Nearshore waters, ocean environment not being formed new pollution, should be green harmless improvement novel method.For this reason, existing in the world multiple ballast water processing, they are mainly:
1, filtration method
In the ballast operating process,, can play the effect that prevents and reduce the harmful organism suction from water ballast by using the filtering system on the ship that a certain size biology is separated.
Filtering the validity that surpasses filter screen aperture object is 95%-98%, and the thickness aperture that generally is used for the wedge filter system of water ballast is respectively 500 μ m and 50 μ m.
2, ultraviolet method
Wavelength is that the ultraviolet ray of 253.7nm has killing action to biological and pathogenic agent.Because the organic solute in the seawater has the intensive sorption to the ultraviolet ray of this section wavelength, and suspended substance is to its barrier effect, so can influence treatment effect.Another shortcoming of this treatment process is that some little biologies may not obtain handling under the shadow than mcroorganism and just left the UV treatment unit, and turbid water can reduce ultraviolet penetrativity.Behind the large-scale microorganism of filtering with the UV treatment water ballast be a kind of effectively and the method that allows of environment, this technology all has no adverse effects to pipeline, pump etc.
3, electrolytic process
Chlorine is a kind of with a long history, sterilizing agent efficiently, extensively applies in the disinfecting of tap water.The disinfectant properties of chlorine is relevant with temperature and duration of contact.Domestic existing research electrolytic seawater obtains conclusion as the treatment process of water ballast: seawater can generate multiple material after by electrolysis, as ClO
-, Cl
2, strong oxidizing property material such as HClO, they are greater than the corrosion speed of hull in ortho-water to the corrosion speed of hull.Generated a series of toxic byproducts that have simultaneously, such material is discharged in the ocean can cause certain murder by poisoning to hydrobiont.
4, ozone method
Ozone is the very strong but unsettled oxygenant of a kind of oxidisability, and kill virus and bacterium comprise spore fast, and ozone can be decomposed into oxygen very soon, when water temperature 20 is spent, can lifetime in water less than 30min, so very little to the influence of environment.Producing of ozone is fairly simple, preparation in the air at sea.Compare with system chlorine device, the initial outlay total expenses of ozone equipment is higher relatively.When ozone dosage is big, can promote the corrosion of hull and equipment, and ozone can with the bromide reaction in the seawater, so use the ozonize water ballast to need very big dosage separately.
Above-mentioned 4 kinds of methods all have limitation separately, and the water ballast pact is approaching day by day execution date, and the ballast water treatment technology of anxious To be improved occurs, and this technology can reach the requirement of IMO water ballast pact, simultaneously safety and environmental protection, reliability height.
