Description
Technical field
The utility model belongs to the ballast for cruising water-treatment technology field, especially relates to a kind of apparatus for treating ship ballast water.
Background technology
At present the quantum of international trade is that transportation by oceangoing vessel realizes more than 90%, when ballast water for ship without processing or process when thoroughly just not carrying out the strange land discharging, will very likely cause the alien species invasion.As have " ctenophore event ", " vibrio cholerae pollution incident " of Typical Representative etc.Halobiontic invasion has non-reversibility, and its caused environmental hazard can grow in intensity along with the transition of time, is therefore classified as four greatly one of harm that the ocean faces by International Maritime Organizaton (IMO).
Carry out the harm that the discharging of ballast water and sediment strange land brings for effectively controlling oceangoing vessel, member states's diplomacy conference that IMO holds has been passed through " Management of Ships ' Ballast Water and settling management and control pact " on February 13rd, 2004 in London, this pact has been opened for various countries' official approval on June 1st, 2004 and accepted.
China is as the category-A member of the UN Security Council of shipping big country and IMO, the present oceangoing vessel tons gross of China accounts for 3.4% of world tonnage, it is second-biggest-in-the-world sea transport state, industrialization lags behind may meet with technical monopoly and trade barrier, exploitation has independent intellectual property right and practical ballast water treatment technology, and tool is of great significance.
Different according to the route of ship's navigation and zone, the ballast water type also has difference, and water ballast may be fresh water, brackish water or seawater.The biological species that contains in the water ballast mainly contains algae, bacterium, fungi, mould, virus, fish-egg, protozoon etc., easily discharges the algae toxin when wherein algae is killed under conventional means, causes secondary pollution; Part bacterium and fungi can form gemma and spore under certain unfavourable condition, activity recovery gradually again when adverse environment is removed, so be difficult to kill fully.
Ballast water treatment technology commonly used comprises the methods such as traditional filtering method, Ozonation, electrolytic process, ultraviolet disinfection at present, and prior art is the processing for seawater ballast water mostly, when the route of ship's navigation and area change, the ballast water type also will change, and single treatment process can't be processed it.
The traditional filtering method is after water ballast is carried out coagulation-flocculation treatment, filter with filtering layer, thereby purify water, but its clearance to be limited, especially then can't remove fully the less bacterium of particle diameter, fungi, virus.
The ozone oxidation method for disinfection mainly is by the required enzyme of the inner glucose of decomposing bacteria, or organoid and DNA, the RNA of destruction bacteriophage, or in the intrusion cell, act on lipoprotein and the inner lipopolysaccharides of adventitia, make the distortion of bacterium generation permeability and dissolving death.But the problem that exists is that occupation area of equipment is larger, installs restricted on the ship; Ozonated sea water can produce the objectionable impuritiess such as bromate, may produce secondary pollution.
Ultraviolet sterilizing method mainly is with the function of destroying nucleic acid microorganism to be caused death by the radiation injury to microorganism (pathogenic agent such as bacterium, virus, gemma), thereby reaches the purpose of sterilization.The problem that ultraviolet ray is used for the processing existence of water ballast is: 1, seawater contains a large amount of suspended matter meeting shielding of ultraviolet to the irradiation of biology and pathogenic agent, affect treatment effect, and energy consumption is very large; 2, the treatment effect quality depends on the size and geometric of microorganism to a great extent, such as seaweeds, because its size and color, the dose ratio bacterium that needs is large, bluish-green marine alga is to ultraviolet resistivity extra-heavy, kills large 2 one 3 grades of the quantity that radiation quantity that its needs needs than killing bacteria; 3, some microorganism has possessed stronger self-repairing capability in long-term natural evolution process, can be to anti-ultraviolet processing, and some bacteriums and plant plankton also have similar repair ability, and treatment effect is undesirable.
Electrolytic process is to utilize the Cl that produces when electrolysis
2, C1O
2, HC1O, C1O
-Microorganism is killed or press down to be lived etc. efficient oxygenant, chlorine ion concentration is the important operating parameter of electrolytic process in the water.Boats and ships are different because of the waters of its navigation, and the characteristic of its water ballast is also different, mainly it can be divided into seawater, fresh water and brackish water.Brackish water is because of its residing geographical position, the exchanging form with seawater, evaporated, precipitation, freeze, the impact of ice-melt and land runoff, distribution of the salinity is uneven.Be determined by experiment chlorine ion concentration comparatively suitable preparing chlorine by electrolysis more than 15000mg/L, chlorine ion concentration is still feasible greater than 8000mg/L, but efficient is lower, and energy consumption is higher, chlorine ion concentration is not suitable for electrolysis less than 8000mg/L, need to replenish salt such as the need electrolysis and improve its chloride ion content.
Ultrasonic sterilization is a sterilizing and algae-removing technology of development in recent years, the heat effect that it utilizes the ultrasonic cavitation effect to be accompanied by, mechanical effect, chemical effect, biological effect comes deactivation biological, can produce up to the high temperature of 1900～5200K at ul-trasonic irradiation bubble and small interface place and surpass the high pressure of 50MPa, temperature can raise 10% at per second, and with strong shockwave and the speed per hour jet up to 400km/h, these conditions can be to open the algae air bag, destroy cell wall breaking, impel the zoogloea depolymerization, add its water burning, pyrolytic decomposition and very strong OH and the H of generation oxidisability
2O
2Material, thus effectively realize the bioinactivation of ballast water for ship.But supersonic method has the duration sterilization effect because containing chlorine residue unlike electrolytic process.
Some built-up type sterilising plants also appear at present, as electrolysis, ultrasonic wave and microwave, ultraviolet one or more serial or parallel connections are used, but because ballast water for ship relates to seawater, fresh water and brackish water, and the biological species that may comprise is various, the bad adaptability that causes the device of these combination techniques, can not process thoroughly various types of water ballasts, treatment effect is undesirable.
