Description
Technical field
The present invention relates to sterilization algae removing equipment, be meant a kind of micro-current electrolysis device for sterilizing and removing alga especially.
Background technology
Cyanobacteria (cyanobacteria) also claims blue-green algae or blue-green algae (blue-green algae).Do not have nuclear membrane, kernel in their the nucleus structure, belong to prokaryotic organism, do not carry out mitotic division, cell walls is also similar to bacterium, is made up of peptidoglycan, and Gram-negative is so they belong in the prokaryotic micro-organisms.
Cyanobacteria is a unicellular organism, and is individual bigger than bacterium, and general diameter or width are 3-15 μ m.But cyanobacteria seldom with single individual life, normally still flocks together after division, forms thread or single celled colony.When many individualities flock together, can form very big colony, naked eyes are as seen.Cyanobacteria mainly is grown in the water body top layer, and promptly between the 0.5m of underwater, most cyanobacterias are blueness or blue-greenish colour, so people claim still that traditionally it is blue-green algae or blue-green algae.
Cyanobacteria is widely distributed, from the South Pole to the arctic, and all visible its trace from the ocean to the high mountain.They often are grown in rock, bark or grow in pond, lake, breed vigorously, and the color that makes water body changes with the color of cyanobacteria itself.Careless fishy smell or frowst can take place in the kind that has.
Cyanobacteria contains pigmentary system (mainly contain algocyan, contain chlorophyll α, carotene or phycoerythrobilin in addition).Differ owing to contain the ratio of various pigments in every kind of cyanobacteria cell, so, color such as blue, green, red may be.The nutrition of cyanobacteria is simple, does not need VITAMIN, and as nitrogenous source, kind that can fixed nitrogen is a lot of with nitrate or ammonia.Some kind has circular heterocyst (hererocyst), is generally prolonging filament or individually distribution at one end, is the place that cyanobacteria carries out nitrogen fixation.Cyanobacteria is put the photosynthesis of oxygen, is obligate photolithotrophy microorganism, and its reaction is as follows
CO

These characteristics are similar to general algae.Its breeding is based on fragmentation, and a few species has spore; Thread cyanobacteria also can grow body and breeds by breaking to form, and does not have sexual propagation.
In water body, enter the material of nitrogenous in a large number and phosphorus, cause body eutrophication, then make the cyanobacteria excessive multiplication, the water surface is covered and make water body form the phenomenon of various different colors, be called " wawter bloom " (water bloom) in fresh water, be called red tide at saline waters.The cyanobacteria of energy formation " wawter bloom " comprises some kinds in the genus such as microcystis kutz (Microcystis), Anabaena (Anabaena), Oscillatoria (Oscillatoria)." wawter bloom " that formed by cyanobacteria often has severe toxicity, as coppery Microcystis aeruginosa (Microcystis aerugeosa) and wawter bloom anabena (Anabaenaflos-aguae) etc., poultry or livestock is drunk behind this water less than in one hour even the several minutes and just can be poisoned to death, and can cause that hydrobiont (as fish) is poisoned to death.Thereby hindered water reoxygenation because a large amount of cyanobacterias cover the water surface, simultaneously a large amount of cyanobacteria cause deaths and corruption cause water body thereby anoxic and smelly, the formation vicious cycle.(Ren Nanqi etc. pollute controlling microbial, p38-39, press of Harbin Institute of Technology published in 2002).
In the natural water body, except a large amount of blue-green algaes that body eutrophication produces, many unwanted bacterias and virus etc. are still arranged, as intestinal bacteria (Coliform), enterococcus bacteria (Enterococcusgroup), cholera bacteria (Vibrio cholerae) or the like, these thalline are in the water ballast that ship's navigation is gathered, might be taken to other waters, be caused eco-catastrophe.Be generally and reduce excessive bending moment of boats and ships and shearing force, alleviate the hull vibrations, nearly all boats and ships all are provided with pumping system.Experiment showed, and have a large amount of bacteriums, pathogenic agent and other some microorganisms non-indigenous in the water ballast that accumulates in for a long time in the water ballast tank.In being rich in the water ballast tank of ferro element, they can be bred rapidly and survive several weeks even longer time.When boats and ships are discharged these external or new microorganisms, can cause local ecotope dysequilibrium.Generally speaking, these microorganisms are harmful, in case the leakage of water ballast takes place, pollute the environment, boats and ships, and the health that threatens personnel also may cause the damage of goods.Along with the enhancing of people's environment protection idea, this problem seems more and more outstanding.IMO (InternationalMaritime Organization, International Maritime Organizaton) investigation result is found, 4 kinds of poisonous algae such as dinoflagellate propagate into China by ballast water for ship, and cause large-area red tide disaster (Liu Fubin, boats and ships, the 4th phase of in August, 2006).State Environmental Protection Administration in 2004 announces, China since the direct economic loss that biotic intrusion causes up to 57,400,000,000 yuan, wherein the marine organisms invasion is one of main reason.
At this class situation, people carry out many-sided effort very early, in the hope of avoiding harmful organism and pathogenic agent by other waters of water ballast pollution or cause eco-catastrophe.As far back as nineteen eighty-two, " nineteen eighty-two United Nations Convention on the Law of the Sea " (UNCLOS that IMO puts into effect, United NationsConference on the Law of the Sea) the 196th (1) bar regulation, " Marine Environmental Pollution that various countries should take all necessary steps and cause owing to use technology under its administration or control to prevent, to reduce and to control, or owing to deliberately or accidentally cause ocean environment that great and deleterious variation may take place at the external or new species of a certain specific region introducing of ocean environment "; 34 (b) bar of world's Sustainable development summit implementation plan in 2002, recognize that boats and ships uncontrolledly discharge the transfer that water ballast and settling have caused unwanted aquatic organism and pathogenic agent, environment, human health, property and resource are damaged or damage, call action of parties to get up to accelerate to formulate the measure that water ballast is introduced the adventive problem that solves; Some countries have acted unilaterally and have entered the risk that unwanted aquatic organism and pathogenic agent are introduced in its harbour to prevent, to reduce to greatest extent and finally to eliminate by boats and ships at present, and caused global extensive concern on this problem, urgent need will be formulated rule and the guide rule that a whole world is suitable for, it is effectively implemented and unified the explanation, continue to advance the development of safer, effective Ballast Management method, thereby continue to prevent, reduce to greatest extent and the final transfer of eliminating unwanted aquatic organism and pathogenic agent; On this basis, IMO formulates " international shipping water ballast and settling control and management contract ", by controlling and manage environment, human health, property and the resource risk that ballast water for ship and settling cause with the transfer that prevents, reduces to greatest extent also final elimination unwanted aquatic organism and pathogenic agent, and the unnecessary negative influence of avoiding this kind control to cause, and the development of encouragement, promotion relevant knowledge and technology; Though this pact U.S. and China is not signature as yet at present, most developed countries sign, and realize the management of water ballast in the global range by this treaty, just a matter of time.
Technology and corresponding the equipment and facility at external unwanted aquatic organism, pathogenic agent invasion are administered and prevented to the blue-green algae of water body in large must possess following feature:
(1), killing microorganisms and pathogenic agent speed must be very fast: otherwise, in water body in large, water after handling enters in the body water once more, if what add is biocide, will be very fast diluted and weaken sterilizing ability, add the microorganism of not killing in a large number, very fast meeting large-scale breeding, regulation effect is very poor; If be applied in the ballast water treatment, water ballast suction and discharging have only the very short time by device, if killing microorganisms and pathogenic agent speed are fast inadequately, the water body after it is handled just can not be up to standard;
(2), kill efficiency height: the discharging water ballast standard of performance of the regular D-2 bar regulation of " international shipping water ballast in 2004 and settling control and management contract " must satisfy:
(a). minimum size is less than 10 more than or equal to 50 microns survived in biology in every cubic metre; And
(b). minimum size is less than 50 microns but be less than 10 more than or equal to 10 microns survived in biology in every milliliter; And
(c). as a kind of HUMAN HEALTH standard, target microorganism should be less than following concentration:
(i). poisonous vibrio cholerae is less than per 100 milliliters 1 colony-forming unit (cfu) or less than 1 cfu of each gram (weight in wet base) zooplankton sample;
(ii). intestinal bacteria: be less than per 100 milliliters of 250cfu; And
(iii). enterococcus bacteria: be less than per 100 milliliters of 100cfu;
(3), can not produce secondary harm to ecotope;
(4), processing power is big: the eutrophication problem in water body in large such as lake, the processing power of sterilization algae removal is one of key factor; Handle for ship ballast water, boats and ships can not stop for a long time, and general requirement unit processing power is at 300M
3More than/the hr.
The improvement technical system of existing body eutrophication and blue-green algae, and ballast water treatment technical system, mainly contain: (1) medicament of killing livestock, (2) filter screen drags for collection and membrane technology, (3) ultrasonic technique, (4) high pressure algae removal, (5) biological treating, (6) ecological management, (7) ultraviolet sterilising technology, (8) electrolysis produces the active substance sterilising technology.
The medicament of killing livestock
Chinese patent application number 02100332 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 releases are a kind of by glutaraldehyde, the composite efficient aldehyde insecticide that quaternary amine constitutes; Chinese patent application numbers 200510025395 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 (World Intellectual Property Organization) 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 ClO
2As 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 the little water body effect of local, 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.
Filter screen drags for collection and membrane technology
Filter screen drags for collection and filters this class mechanical means and remove blue-green algae, as the summer of present Kunming Dianchi lake at the blue-green algae large-scale outbreak, and for the improvement of water body in large, but an utterly inadequate amount, difficulty becomes effective; This technology and corresponding device thereof can not effectively be removed unwanted bacteria (poisonous vibrio cholerae, intestinal bacteria, enterococcus bacteria etc.) and virus, can't satisfy the requirement of ballast water treatment, are unsuitable for ballast water treatment.How this technical scheme is as the supplementary means of filtering macrobead suspended substance or silt in the water treatment.
At present, developed country adopts membrane technology and corresponding device thereof more, 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; Administer and the quick big flow water body of mobile for the blue-green algae of water body in large, running cost is higher, and processing power can not satisfy corresponding requirement.
Ultrasonic technology
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 a kind of interior 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 are applied to strengthen flocculating effect; As Chinese patent application number 200610085548 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 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 hyperacoustic damage 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 is announced and international monopoly WO03095370 are released, successive supersound process water ballast device, its ultrasonic transducer faces same problem.
But administer and the quick big flow water body of mobile for the blue-green algae of water body in large, existing ultrasonic processing apparatus is except the problems referred to above, if adopt ultrasonic technique to handle separately, remain at energy consumption high the running cost height, killing effect is difficult to unfavorable factors such as assurance, does not possess operability.
The high pressure algae removal
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 but administer for the blue-green algae of water body in large, there is the energy consumption height equally in the high pressure algae removal, unfavorable factors such as running cost height do not possess operability; At ballast water treatment, also there is the problem of processing power and running cost.
Biological treating
For the fresh water eutrophication water, people place hope on biological treating, but biological treating might cause biological disaster to local species because of introducing adventive.And blue-green algae is actual to be cyanobacteria, and the toxin of generation just can make fish, poultry dead in several minutes in the ppm level; Satoshi Nakai is (ALGAL GROWTHINHIBITION EFFECTS AND INDUCEMENT MODES BY PLANT-PRODUCING PHENOLS SATOSHI NAKAI in the work report that 2001 deliver
*YUTAKA INOUE andMASAAKI HOSOMI, Water Research, Vol.35, Issue 7, and May 2001, Pages 1855-1859) point out, grass and other waterplant can reduce the eutrophication degree of water quality to a certain extent, but rarer plant can discharge the aldehydes matter of the growth that can suppress cyanobacteria.For the red tide of seawer system, biological treating is unpractical.Biological process still is in the exploratory stage to the improvement of algae at present, still unmatchful in the world extensive eutrophication water adopts the successful precedent of biological control blue-green algae, and, be difficult to blue-green algae be realized overall the inhibition with a kind of or limited several microorganisms, phage because the cyanobacteria kind that blue-green algae comprised is more.In addition, consider that from processing speed and efficient the biological treating technology is not suitable for the processing of water ballast.
Ecological management
Polluting under the controlled situation in external source, recover aquatic higher plant to improve the self-purification capacity of water body, is the key of lake eutrophication improvement and ecological recovery.But this method responding time is longer, is difficult to realize in a short time the blue-green algae control of eutrophication water.And the blue algae bloom of eutrophication water can cover the water surface, hinders water reoxygenation, and simultaneously a large amount of cyanobacteria cause deaths and corruption consume the dissolved oxygen of water body and make water body smelly, cause fish kills and other hydrocoles death, the formation vicious cycle.Equally, the ecological management technology is not suitable for the processing of water ballast.
The ultraviolet sterilising technology
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 20051114 disclosed ultraviolet ray water treatment sterilization systems, 200610093390 disclosed household drinking water treating machines.
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 20060112 disclosed acousto-optic sterilization treatment device for drinking water and the 200520087812 disclosed sea filter device with mighty ultraviolet disinfection that are applied to the breeding seawater processing; U.S. Pat 5738780 combines ultra-violet sterilization and dc electrolysis, is applied to ballast water treatment.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.
Electrolysis produces the active substance sterilising technology
To add salt, produce the technology and the device of hypochlorous acid sterilization then by electrolysis, forefathers have many work, comprise Chinese patent application number 200610042972.2 disclosed " a kind of two-functional electrolytic generators ", disclosed 200510111126.7 " a kind of small-sized disinfected water generator and using method thereof ", disclosed 200520077629.2 " portable water source sterilizing machine ", disclosed 200510023766.2 " preparation method of high concentration hypochlorous acid disinfecting liquid ", than directly adding chlorinated lime, throw in dioxide peroxide, schemes such as hydrogen peroxide are convenient, save cost, but can increase the salinity of water of handling, especially for the big area lake, the sterilization of the eutrophication water of reservoir, algae removal is handled, under the long-term operation condition, the measure that all add medicament and increase water salinity all is unacceptable.
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 disclosed ballast water for ship (water ballast) electrolytic treatment systems, Chinese patent application number 200480027174 disclosed treating water reservoirs similarly that adopts electrolysis to produce hypochlorite, with chlorion, the water molecules electrolysis handled in the water body is the material (ClO-with high oxidation activity, OH, H
2O
2, (O)), 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.
There are two kinds of defectives in this method and system:
(1), the interelectrode distance of system satisfies the electrolysis design requirements of water ballast in seawater, can not satisfy the requirement of fresh water system, because boats and ships are at the harbour of shipping waters and stop, has plenty of close rivers mouth, belong to fresh water zone, the two is owing to the electrolysis voltage that water body specific conductivity difference causes changes too greatly.
The voltage that electrolysis system puts between anode and the negative electrode has three parts to constitute, referring to Fig. 1, wherein:
U1: electropotential and polarization overpotential by anodic oxidation reactions constitute, if the polarization phenomena of electrochemical reaction can be ignored, for specific reaction system (reaction density, pH, temperature-resistant), U1 is constant substantially, does not change with current density;
U2: the pressure drop that the resistance of solution causes, electrical conductivity of solution are low more, and then resistance R is big more, raise with the increase of current density;
U3: electropotential and polarization overpotential by cathodic reduction reaction constitute, if the reaction polarization phenomenon can be ignored and do not exist negative electrode to be stain, coat phenomenon by suspended substance and inorganics, for specific reaction system (reaction density, pH, temperature-resistant), U3 is constant substantially, does not change with current density.
Want the certain sterilization of guarantee system, algae removal ability, Faradaic current I requires constant on certain numerical value basically, if interelectrode distance is that d is (for all openly take the system of electrolytic process at present, all less than the design that changes interelectrode distance in system consideration in service), electrode area is S, the water body specific conductivity is μ, then has following relation:
U
2＝IR＝I×(d/(S×μ)) (1)
For certain electrolytic system, owing to I, d, S are determined value, but dissimilar water has different specific conductivity, and seawer system is 30000 μ S/cm; The river mouth water body, at ebb tide, current show as the single flow direction to the ocean, though influenced by oceanic tide, the water chemistry composition in the district that crosses this moment is similar to river water quality, specific conductivity can be between 50-500 μ S/cm; During slack tide, dropping of existing river also has tracing back of trend, and the water quality in the district that crosses this moment is complicated, and unstable; At the incoming tide, morning and evening tides is big to Hekou District influence, the seawater very dark distance in the river mouth of tracking, and the chemical constitution of the Qu Zhongshui that crosses this moment then shows the seawater feature.Therefore, when the river mouth water body between 50-500 μ S/cm the time, at least differ more than 60 times with ocean water body, from (1) formula as can be known, put on the voltage U 2 on the water body between anode and the negative electrode, have the difference more than 60 times at least, be difficult to guarantee that electrolytic system can satisfy boats and ships and run on the requirement of different waters to ballast water treatment in the safety voltage scope.
(2), there is scale formation in negative electrode in the fresh water system, and cause the resistance between negative electrode and the water body sharply to increase, influence electrolytic efficiency, guarantee current constant if desired, then Zheng Ti electrolysis voltage sharply raises, and system can't normally be moved.
In the fresh water system, electrolytic process mainly is CaCO in the fouling of negative electrode
3, because cathode surface and cathode zone adsorb a large amount of positively charged ions to satisfy charge balance, cation concn does not have very big difference, Ca in the water body
2+Electric charge is higher, at cathode surface and cathode zone enrichment, the HCO in this regional area and water body
3 -Following reaction takes place:
Ca

Jeffrey A.Franz is at research (the Water Research of the pollution of producing the electrode surface that cathode deposition/fouling causes in the oxygen process about electrolysis to the influence of aerobic biodegradation system, Vol.36, Issue 9, May 2002, Pages 2243-2254) points out in that the cathode surface precipitation is mainly CaCO
3Formerly apply for a patent the self-cleaning sterilizer of 99253589 disclosed water tanks in the long-time running process, negative electrode has tangible CaCO
3Precipitation is used in the area that hardness is higher, even because the CaCO that reaction (2) produces
3Precipitation causes the electrolysis line clogging; In please the patent No. 03156596.4 " built-up type micro-current electroanalysis water technology and device ", though in the process that ultrasound probe counter electrode surface is cleaned, scale problems is eased, but might produce adverse influence to the aquatic ecological system, in the long-time running process, still there is slight scale formation in cathode surface; Though this device can be realized the blue-green algae of big area eutrophication water is effectively administered and inhibition, organizes parallel electrode more, makes erecting stage (ship, floating drum) in moving process, causes to turn to difficulty; And hydrocoles (fish) enters between the electrode easily, causes electric shock, and forms electric pole short circuit; The water that this device is fixed in the tank sea farming carries out electrolysis sterilization, disinfects by tank, handle seawater passes through to install electrolyzer with the flow velocity of 1.0～1.5m/s tank, white precipitate (bottom land ionization electrode edge 2cm) in a small amount appears in (more than at least 3 months) its bottom land after the long-time running, but the not precipitated covering of cathode surface.Chinese patent application number 200520114686.3 " the blue-green algae controlling devices " released face similar CaCO equally

3There are three kinds of crystal formations: calcite (calcite), aragonite (aragonite) and ball aragonite (vaterite), calcite (calcite) forms dense structure easily, difficult drop-off on electrode; Aragonite (aragonite) generally could form in (more than 80 ℃) crystallization in the presence of the template or under the high temperature, growth, and electrolytic process does not possess such condition; Ball aragonite (vaterite) short texture comes off easily.We will be applied to the white deposits of the built-up type micro-current electroanalysis water treatment device of sea farming sterile environment, the white fouling of the cathode surface of the built-up type micro-current electroanalysis water treatment device of freshwater aquiculture water treatment, the white fouling of the cathode surface of the self-cleaning sterilizer of water tank that uses with the high building water tank scrapes, carry out field emission electron scanning analysis (SEM) photo and infrared (IR) absorption analysis respectively, result such as Fig. 2 a, 2b, 2c and shown in Figure 3, wherein, the a curve is the Absorption by Sea Water analytic curve among Fig. 3, the b curve is a fresh water absorption analysis curve, and the c curve is the tap water absorption analysis.
From Fig. 2 a as can be seen, the white precipitate particle of sea farming electrolysis treatment body is less relatively, and major part is spherical; Fig. 2 b and Fig. 2 c are respectively the SEM photo of white fouling of the cathode surface of the fouling of cathode surface of electrolysis treatment system of freshwater aquiculture and the self-cleaning sterilizer of water tank that the high building water tank uses, and particle is bigger; Dui Ying IR absorption spectrum Fig. 3 shows therewith, and curve a is the white precipitate particulate infrared absorption spectrum of sea farming electrolysis treatment system, except the carbonate in-plane bending vibration v4 charateristic avsorption band 712cm of calcite (calcite)

2Adsorbed by Pt, Ir, Ru, Rh, Pd and Ti, cause volumetric expansion to cause between coating and the core and peel off, cause coating and active substance to come off loss of catalytic activity.
