Description
Technical field
The utility model relates to environmental technology field, especially a kind of efficient inactivation and energy-conservation ship ballast water treatment system.
Background technology
One of four big threats that current ocean environment is faced are exactly to spread through sex intercourse from the harmful organism invasion, and ballast water for ship is to cause harmful organism to invade topmost route of transmission.It is the best approach that solves the harmful organism invasion that causes because of water ballast that ballast water for ship is handled.
It is a focal issue that the whole world is paid close attention to that IMO points out to administer the invasion of ballast water for ship harmful organism, does not advocate different regions and adopts different improvement systems to administer water ballast, and its basic demand is: aboard ship handle; Cost is desirable, and equipment is small and exquisite, is convenient to operation; Nearshore waters, ocean environment is not formed new pollution; Treatment facility and operational safety, reliable.
Because the ship loading water ballast water yield is huge, and require the processing ballast time to lack, add the restriction of ocean environment and marine economy Sustainable development, the method (or medicament) of general killing microorganisms all can not satisfy the requirement of administering the invasion of ballast water for ship adventive.Though certain methods is successful, effective in the laboratory, administers the ballast for cruising requirement that all is difficult to satisfy ocean environment and Sustainable development thereof waterborne in case be used in.
The treatment process of water ballast mainly contains mechanical process, physics method and chemical method etc. at present.Below, above-mentioned three kinds of methods make brief of the introduction respectively.
1, mechanical process
Mechanical process mainly contains methods such as filtration, cyclonic separation, marine replacing, precipitation and flotation.
In the filtering technique, developed country adopts membrane technology and corresponding device thereof mostly, and filtering microorganism, planktonic organism and bacterium are as Japanese Patent JP2005342626, JP20060099157, JP2006223997, JP2005342626, international monopoly WO2007114198, all adopt membrane technique with seawater or bacterium in fresh water and the microbe filter of suction as water ballast, this class technology needs higher pressure with device, and power consumption is big, and film is easy to contaminated and obstruction; For the big flow water body of quick mobile, running cost is higher, and processing power can not satisfy corresponding requirement.
Cyclone separation process can be removed larger-size biology in the water ballast, but when the proportion of microorganism and seawater was approaching, this method just was restricted.The marine fado of changing need carry out again design to the pipeline of existing vessel and cabin, and existing vessel is using and operating aspect just is restricted.Precipitation and flotation process were once done research at the theoretical side of water ballast, but also were unsuitable at present using on the ship.
2, physics method
The physics method mainly contains heat treated, ray technology, microwave technology and pressure converter technique etc.
The heat treated method is to utilize the unnecessary heat of main frame to kill microorganism in the water ballast, and thermal treatment is feasible aspect health and safety, but the hot water ballast of discharging may cause the problem of environment aspect to public waters.
Ray technology comprises ultraviolet technique and gamma-rays technology etc.Radiation effect by ray causes microorganism integral part generation chemical reaction, reaches the effect of killing bacteria.Because water body itself to ultraviolet strong absorption effect, makes the scope of rentschlerization and sterilization ability be restricted, general ultraviolet disinfection technology is applied to handle lower small volume water body of load and the water body that circulates more.As Chinese patent application number 200510019793.2 disclosed ultraviolet ray water treatment sterilization systems.U.S. Pat 2004134861 and US2005211639, international monopoly WO2004002895 and WO2005110607 release the ultraviolet treatment of ballast water device continuously that adopts many group ultraviolet lamps to produce respectively; In addition, ultraviolet irradiation and combination of ultrasound, can strengthen sterilization effect, as Chinese patent application number 200610023241.3 disclosed acousto-optic sterilization treatment device for drinking water and the 200510104266.1 disclosed sea filter device with mighty ultraviolet disinfection that are applied to the breeding seawater processing; U.S. Pat 5738780 is applied to ballast water treatment with ultra-violet sterilization and direct current catalyzed combination together.But these technology still are subjected to the restriction of the scope and the sterilization ability of rentschlerization, for the sterilization effect of high loading, big flow water body and water body in large, and still can not be satisfactory.Though ray technology can be not controversial at aspects such as safety, health and environment, might make the microorganisms transgenation that is subject to processing.
Microwave technology comprises uses hyperacoustic various microwave technologies.Ultrasonic wave not only has the intensive vibration, but also have cavatition and produce a large amount of microjets, can make liquid that wall of container is produced the intensive shock action, such function is applied to ultrasonic cleaning, also be applied to the intensified response effect, as Chinese patent application number 200510117457.1 a kind of electrolysis wastewater treatment process and the devices of being announced based on ultrasonication, the method and the device thereof of a kind of ultrasonic wave water treatment of being announced with Chinese application number 99120675.4 are applied to strengthen flocculating effect; As Chinese patent application number 200610085548.6 method for treating wastewater of azo dye of being announced and German patent DE 19919824 disclosed oxidation organotin technology, adopt ultrasonic wave to promote the carrying out of chemical reaction.The microcell high pressure that ultrasonic cavitation produces, can be used for the fragmentation of cell, but mostly such effect is ultrasonic energy is converged in the less zone and could realize, therefore, present ultrasonic technique and corresponding water treatment device for the small volume water body, and can adopt the water body that circulates, it is bigger to implement operability, as Chinese patent application number 200610023241.3 acousto-optic sterilization treatment device for drinking water of being announced.
(28～200KHz) are added on pipeline outer wall to Japanese Patent JP2006007184, will carry out sterilization algae removal by the water ballast of pipeline by ultrasonic wave and handle with ultrasonic transducer; JP2005021814 then provides corresponding water ballast tubular ultrasonic device for sterilizing and removing alga, in the device ultrasonic transducer is installed on the casing both sides, and the water route is passed through from casing, microorganism killing in the water body that ultrasonic wave will be passed through; These two parts of patents are not all considered the damage of ultrasonic wave for the ultrasonic transducer piezoelectric ceramics that is installed on opposite tube wall or casing, and can not ignore equally the damage of piezoelectric ceramics perpendicular to the reflection echo of ultrasonic transducer, otherwise directly influence the life-span of ultrasonic transducer, thereby reduce the operation stability and the reliability of device.A kind of annular that ultrasonic wave water treatment machine that number of patent application 98236857.7 is announced and international monopoly WO03095370 are released, successive supersound process water ballast device, its ultrasonic transducer faces same problem.But the quick big flow water body of mobile, existing ultrasonic processing apparatus except the problems referred to above, if adopt ultrasonic technique to handle separately, remains at the energy consumption height, and running cost height, killing effect are difficult to unfavorable factors such as assurance, do not possess operability.
The method that also has a kind of sterilization is exactly the method that changes by rapid pressure.High pressure sterilization and algae removal, be to adopt water body is pressurized to a certain degree, make the cell rupture of bacterium and algae, as Japanese Patent JP2007021287, JP2005270754, JP2005254138, variation by pressure, also can reach the effect that compares favourably with ultrasonic wave, but the noise that the pressure change transmodulator produces may influence crewman's health, can damage the surface and the structure of water tank simultaneously.
3, chemical method
The chemical method that is used for processing ballast at present has medical method, electrolytic seawater method, catalytic oxidation etc.
Chinese patent application number 02100332.7 discloses a kind of brominated composite biocide of oxidized form-bromine chlorine prestige that is applied to service water field and public place, reusing sewage field; Chinese patent application number 200510025284.0 releases are a kind of by glutaraldehyde, the composite efficient aldehyde insecticide that quaternary amine constitutes; Chinese patent application numbers 200510025395.1 discloses a kind of biocide that contains isothiazolinone, dodecyl dimethyl benzyl ammonium chloride, is used for sewage disposal; The disclosed international monopoly WO03002406 of WIPO adopts the sterilization of copper anode generating cu ions electrolytically.The bio-toxicity of this class biocide is bigger, and the residence time is long, still can be applied to the germicidal treatment in circulating sewage or the cooling water system at home, is not suitable for big area eutrophication water such as lake and needs discharged ballast water to handle.
U.S. Pat 2005016933 adopts adds ClO2 as biocide, international monopoly WO2005061388, U.S. Pat 2004099608 and US2003029811, Japanese Patent JP2007144391, JP2006239556, JP2006263563, disclose respectively and adopted filtration and add water technology and the corresponding device thereof of ozone as biocide, this class device and technology, there is not secondary pollution, in low discharge water body or tap water germicidal treatment, certain advantage is arranged, but the sterilization algae removing for big flow water body such as water ballast or large watershed water body is handled, and running cost is very high.
Usually, add the medicament of killing livestock, fine to little water body effect, but be difficult to keep the long period, at 1-2 after week in summer, generally need dosing again.For administering big area, eutrophication water exists running cost height, biocide that there is secondary pollution problems in water body; If be applied to ballast water treatment, its residue is still needed by bio-toxicity and toxicity evaluation.
The electrolytic seawater method is by electrolytic seawater, by the chlorine that produces on anode, and then generates the hypochlorous acid with high-effective disinfecting and comes killing microorganisms and bacterium, and the hydrogen peroxide that produces at negative electrode also has very strong sterilizing ability simultaneously.
International monopoly WO2006058261 discloses a kind of ballast water treatment method and corresponding system, Japanese Patent JP2001000974 disclosed electrolysis treatment water ballast device and electrolyzer that also has Chinese patent application number 200510046991.8 disclosed water electrolytic treatment system of ballast for cruising, Chinese patent application number 200480027174.1 disclosed treating water reservoirs similarly that adopts electrolysis to produce hypochlorite, is that the material with high oxidation activity (is mainly: ClO with chlorion, the water molecules electrolysis of handling in the water body
-, OH

2), cell, RNA, the DNA of bacterium in the water body and algae carried out oxygenizement, make its inactivation and death, thereby reach sterilization algae removal effect, and make the treated water body keep continuing disinfection.Though the method for electrolytic seawater has sterilization effect preferably, after the employing electrolytic process kill bacteria, may produce the carcinogenic substance chloroform, can cause that to second environmental pollution therefore this method exists very big dispute always.
Catalytic oxidation is the method for a kind of advanced person in the present processing ballast aspect.Be exactly the PureBallast ballast water treatment system of Sweden's Alfa Laval Group exploitation by the final technology of approving that a kind of ship ballast water treatment system adopted of IMO in the world at present, and the treatment process that this system adopted is exactly to adopt the method for photochemical catalytic oxidation.Core cell in the PureBallast ballast water treatment system is exactly photocatalyst Wallenius AOT unit, in this unit, titanium dioxide is as catalyzer, under ultraviolet irradiation, generation has the hydroxyl radical free radical of extremely strong oxidisability, and this hydroxyl radical free radical is a present defluorination the strongest outer oxygenant, and its oxidation capacity is hydrogen peroxide and ozone 106～109 times, under the effect of hydroxyl radical free radical, microorganism finally can be degraded to carbonic acid gas and water by chain reaction.But the efficient in the practical application also will depend on crystalline structure, surface imperfection and some influences as extraneous factors such as light intensity, temperature, pH values of titanium dioxide self.
Yet, regrettably, in the prior art, all exist basically equipment cost have high input, consume energy height, pollutant removing efficient low, can not remove shortcomings such as carbon nitrogen amounts of sulphur contaminants simultaneously.
