Description
Technical field
The present invention relates to the water treatment environmental technology field, especially a kind of device of Treatment of Ships'Ballast Water of efficient reduce power consumption.
Background technology
One of four large threats that current ocean environment faces are to spread through sex intercourse from pest invasion, and ballast water for ship is to cause the topmost route of transmission of pest invasion.It is the best approach that solves the pest invasion that causes because of water ballast that ballast water for ship is processed.
International Maritime Organizaton (IMO) points out to administer the focal issue that the ballast water for ship pest invasion is a global concern, does not advocate different geographical and adopts different improvement systems to administer water ballast, and its basic demand is: aboard ship process; Cost is desirable, and equipment is small and exquisite, convenient 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 requires the time of processing ballast short, adds the restriction of ocean environment and Sustainable Development of Marine Economy, the method (or medicament) of general killing microorganisms can not satisfy its requirement.Although certain methods is successfully, effectively, administer the requirement that ballast water for ship is difficult to satisfy ocean environment and Sustainable development thereof in the laboratory.
The treatment process of ballast water for ship mainly contains mechanical process, Physical 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 the methods such as filtration, cyclonic separation, precipitation and flotation.
In the filtering technique, mostly adopt membrane technology and corresponding device, filtering microorganism, planktonic organism and bacterium are such as Japanese Patent JP2005342626, JP20060099157, JP2006223997, JP2005342626, International Application No. WO 2007114198, all adopt membrane technique that suction is fallen as the seawater of water ballast or the bacterium in the fresh water and microbe filter, this class technology needs higher pressure with device, and power consumption is large, and film is easy to contaminated and obstruction; For the large flow water body of rapid flow, running cost is higher, and processing power is difficult to meet the demands.
Cyclone separation process can be removed larger-size biology in the water ballast, but when the proportion of microorganism and seawater approached, the method just was 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, Physical
Physical mainly contains heat treated, ray technology, microwave technology and pressure converter technique etc.
The heat treated method is to utilize the main frame waste heat 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 to public waters the problem of environment aspect.
Ray technology comprises ultraviolet technique and gamma-rays technology etc.Radiation effect by ray causes the composition of the microorganism that chemical reaction partly occurs, and reaches the effect of killing bacteria.Microwave technology comprises uses hyperacoustic various microwave technologies.Ultrasonic wave not only has strong vibration, but also have cavatition and produce a large amount of microjets, can make liquid that wall of container is produced strong shock action, such function is applied to ultrasonic cleaning, also be applied to the intensified response effect, such as Chinese patent application number 200510117457.1 a kind of electrolysis wastewater treatment process and the devices based on ultrasonication of announcing, method and the device thereof of a kind of ultrasonic wave water treatment of announcing with Chinese application number 99120675.4 are applied to strengthen flocculating effect; Such as Chinese patent application number 200610085548.6 method for treating wastewater of azo dye of announcing, 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, implement operability larger, such as Chinese patent application number 200610023241.3 acousto-optic sterilization treatment device for drinking water of announcing.
(28～200KHz) are added on pipeline outer wall to Japanese Patent JP2006007184, will carry out by the water ballast of pipeline sterilization algae removal by ultrasonic wave and process with ultrasonic transducer; JP2005021814 then provides corresponding water ballast tubular type 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 do not consider that all ultrasonic wave is for the damage of 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 affect the life-span of ultrasonic transducer, thereby reduce operation stability and the reliability of device.The ultrasonic water processor that number of patent application 98236857.7 is announced, and a kind of annular of releasing of International Application No. WO 03095370, continuous supersound process water ballast device, its ultrasonic transducer faces same problem.But the large flow water body of rapid flow, existing ultrasonic processing apparatus except the problems referred to above, if adopt separately ultrasonic technique to process, remains in energy consumption highly, and running cost is high, and killing effect is difficult to the unfavorable factors such as assurance, does 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, to adopt water body is pressurized to a certain degree, make the cell rupture of bacterium and algae, such 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 affect crewman's health, can damage simultaneously surface and the structure of water tank.
3, chemical method
Chemical method for the treatment of water ballast has medical method, electrolytic seawater method, catalytic oxidation etc. at present.
Chinese patent application number 02100332.7 discloses a kind of brominated composite biocide of oxidized form that is applied to service water field and public place, reusing sewage field-bromine chlorine prestige; Chinese patent application number a kind of composite efficient aldehyde insecticide that is consisted of by glutaraldehyde, quaternary amine of 200510025284.0 releases; Chinese patent application numbers 200510025395.1 discloses a kind of biocide that is used for sewage disposal that contains isothiazolinone, dodecyl dimethyl benzyl ammonium chloride; The disclosed International Application No. WO 03002406 of WIPO adopts the sterilization of copper anode generating cu ions electrolytically.The bio-toxicity of this class biocide is larger, and the residence time is long, still can be applied at home the germicidal treatment in circulating sewage or the cooling water system, but is not suitable for the big area eutrophication water such as lake and needs the ballast water treatment of discharging.
US Patent No. 2005016933 adopts adds ClO
2As biocide, International Application No. WO 2005061388, US Patent No. 2004099608 and US2003029811, Japanese Patent JP2007144391, JP2006239556, JP2006263563, disclose respectively and adopted filtration and add ozone as the water technology of biocide and corresponding device, this class device and technology do not have secondary pollution, in low discharge water body or tap water germicidal treatment, some superiority is arranged, but the sterilization algae removing for the large flow water body such as water ballast or large watershed water body is processed, 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 again dosing.For administering big area, eutrophication water exists that running cost is high, there is secondary pollution problems in biocide to water body; If be applied to ballast water treatment, its residue is still needed by bio-toxicity and Toxicological Assessment.
The electrolytic seawater method is by electrolytic seawater, by the chlorine that produces at 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 simultaneously also has very strong sterilizing ability.
International Application No. WO 2006058261 discloses a kind of ballast water processing and corresponding system, the disclosed electrolysis treatment water ballast of Japanese Patent JP2001000974 device that adopts electrolysis to produce hypochlorite, the 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 processing reservoir of water similarly is that the material with high oxidation activity (is mainly: ClO with chlorion, the water molecules electrolysis of processing in the water body
-, OH
-, H
2O
2), cell, RNA, the DNA of the 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.Although the method for electrolytic seawater has preferably sterilization effect, after the employing electrolytic process kill bacteria, may produce the carcinogenic substance chloroform, can cause the secondary pollution to environment, therefore this method exists very large dispute always.
Therefore, in the prior art, basically all there is equipment cost low etc. the shortcoming of high, sterilization algae removal efficient that has high input, consumes energy.
A kind of micro-current electrolysis device for sterilizing and removing alga (number of patent application: 200810084187.2) that the contriver releases before this, because this utilization is electrochemical method, this system is difficult to realize filtering the mode that is integrated with processing unit, thereby has excessive defective on the volume.
