Description

Be used for the assorted algae expeling of sea sedge and the sea sedge processing method and the sea sedge inorganic agent of disease control
Technical field
The present invention relates to a kind of assorted algae expeling of sea sedge and the sea sedge processing method and sea sedge inorganic agent of disease control of being used for, it can be removed effectively culturing and adhering to the assorted algae headed by the diatom and grow nonparasitically upon another plant with wedge shape algae, shank algae etc. of being grown nonparasitically upon another plant on the sea sedge cause the bacterium classes such as needle-like bacterium of needle-like bacteriosis (ス ミ ノ リ disease) in sea sedge leaf surface, and then control can be infected sea sedge leaf somatic cell and bring bacteriosiss such as the green statin disease of very big harm, doubtful white rot, red rot, gyalectiform bacterium disease effectively, thereby cultivates healthy breed sea sedge.
Background technology
All the time, have multiple assorted algae and disease of growing nonparasitically upon another plant on the breed sea sedge, this comprises: the wedge shape algae (Licmophora flabellate) that belongs to diatoms, shank algae (Synedra sp.), the Enteromorpha (Enteromorupha prolofera) that belongs to green algae, flat Enteromorpha assorted algae such as (E.compressa), belonging to bacterium with pythium spp (Pythium) is the red rot of pathogen, to intend oil can (Olpidiopsis) genus bacterium is the gyalectiform bacterium disease of pathogen, and be the needle-like bacteriosis (ス ミ ノ リ disease) of pathogen with Flavobacterium (Flavobacterium) or vibrio (Vibrio) bacterium class, the green statin disease, bacteriosiss such as doubtful white rot etc.
As the expeling of these assorted algaes, disease, prevent and treat method, it generally is the tidal period of utilizing tidewater, the sea sedge net is risen to aerial certain hour carry out drying, algae is driven away, disease control to utilize assorted algae and pathogen and sea sedge to mix for the difference of the tolerance of drying.
But, do in the floating streaming breed of operation at the morning and evening tides that can't utilize tidewater, be difficult to handle the expeling of mix algae, pathogen by the drying of sea sedge net.In addition,, look the different of the kind of disease and degree, only can not fully carry out disease control sometimes by doing operation even in the column support type that the morning and evening tides that can utilize tidewater is done operation is cultured.As its solution, developed acid treatment technology (for example special public clear 56-12601 communique), and be widely used.
In the acid treatment technology that at present institute generally uses, use be with organic acid as the preparation of principal component and be diluted to pH with on-the-spot seawater and be about 2 solution, still but have problem to marine environment generation organic loading.In addition, still have these acid treatments the assorted algae and the disease that are difficult to drive away.
For fear of, solve these the problems of the prior art, people always developmental research energetically to environmental influence little and treatment technology efficiently.As one of its R﹠D direction, attempt utilizing electrolyte exactly.These technology be all utilize the electrolyte that obtains by electrolytic seawater or aqueous chloride solution to sea sedge adhere to diatom, particle-bound bacteria is driven away and carrying out washing treatment etc. (for example spy open flat 7-313007 communique, spy open flat 8-140512 communique, spy and open 2003-174828 communique, spy and open 2003-235373 communique, spy and open 2004-33195 communique, spy and open that 2004-81186 communique, spy are opened the 2004-97042 communique, the spy opens the 2004-155706 communique), but the situation of reality is that these technology also do not become perfect practical technique.
Therefore, in the industry cycle urgent practicability of wishing the as far as possible little and sea sedge treatment technology that validity is high of a kind of load to marine environment.
On the other hand, although there has been this technology that has been established of electrolytic sterilizing method, can not but why using the assorted algae of this technology, assorted bacterium treatment technology in sea sedge breed field be by practicability successfully? it is big as the sea sedge net of 1.8m * 18m that one of them big reason is considered to its processing object, and organic amount is very big.
When utilizing electrolyte to carry out sterilizing, this electrolyte typically uses the strong oxidized water that utilizes diaphragm electrolytic cell and generate in the anode chamber.Employed barrier film is that certain ion that produces of a kind of electrolysis or electronics can see through but be difficult to the film of freely through microsecond structure with the many molecules headed by the water in this electrolytic cell.
On the other hand, as the sea sedge net of handling object, its volume is big and the organic matter amount is big, and because of the assorted algae that will drive away coexists and must optionally drive away with the sea sedge that can not damage, so there is the too high problem of concentration of the sterilization components such as chlorine that can not make electrolyte.
Therefore, the a large amount of electrolyte of essential use in processing, thereby it is just discarded after employed electrolyte and the non-once use, but preferably recycle repeatedly, but when making the circulate electrolyte of having handled the sea sedge net that has a large amount of pollutions, in diaphragm electrolytic cell, be easy to generate the obstruction and the breakage of barrier film, be difficult to equipmentization.
In electrolysis mode, it also is known not using the no barrier film mode of barrier film, but the sterilizing power that does not have diaphragm type is poor usually.It is relevant with the pH value of electrolyte that the reason that sterilizing power is low is considered to.Although free effective chlorine density height in the diaphragm-free electrolysis liquid, the pH value is faintly acid~alkalescent.In order to remedy this shortcoming, also the diaphragm-free electrolysis water that has added hydrochloric acid has been carried out studying (for example special fair 4-94785 communique, special permission No. 2619756 communique, characteristic No. 2627100 communique, spy open flat 10-128336 communique, and the spy opens flat 10-266733 communique).
But when the solution of hydrochloric acid had been added in electrolysis, the hydrochloric acid that is added was also by electrolysis, had therefore that the pH value changes in the electrolytic process, its bactericidal action problem of unstable.
In addition, also knownly a kind ofly in by electrolyte, add various organic acid technical schemes for the pH value that reduces electrolyte (for example the spy opens flat 7-313982 communique, Te Kaiping 8-299961 communique, Te Kaiping 10-314746 communique, the spy opens the 2003-170167 communique), when the acid of using acid disassociation index (pKa) less than 4, lactic acid for example, malic acid, citric acid, tartaric acid, during fumaric acid etc., the acid that the material that the oxidisability such as chlorine that electrolysis generated are strong and these degree of ionization are big reacts, therefore how the redox potential and the effective chlorine density of electrolyte can not rise, and, even in case rise, if end to apply electrolysis power, redox potential and effective chlorine density also can promptly reduce, and the problem of the electrolyte with sterilizing power can't be stably supplied with in existence.

Embodiment
Below, embodiment of the present invention are described in detail.
Sea sedge processing method of the present invention is to utilize electrolysis organic acid sea water solution and the electrolyte that obtains carries out that the assorted algae of sea sedge is driven away and the disease control of sea sedge, wherein, above-mentioned organic acid contain acid disassociation index (pKa) be 4 or above organic acid at least a.
In the present invention, be used to prepare electrolyte by electrolyte (stoste) by contain acid disassociation index (pKa) by 4 or above at least a organic acid sea water solution of organic acid constituted, and its pH value is preferably 2~5 scope.
It is 4 or at least a kind (a kind of separately separately or mixture of two or more) of above organic acid, for example propionic acid (pKa 4.87), acetic acid (pKa 4.76), succinic acid (pKa 4.21), butyric acid (pKa 4.8), valeric acid (pKa 4.8), caproic acid (pKa 4.8) etc. that operable organic acid can list acid disassociation index (pKa).From viewpoints such as stink are few and easy to use, preferred succinic acid, acetic acid, propionic acid at least a kind.
In addition, (dissociation constant surpasses 1 * 10-4) acid when using acid disassociation index (pKa) less than 4, lactic acid (pKa 3.86) for example, malic acid (pKa 3.40), citric acid (pKa 3.16), tartaric acid (pKa 3.06), during fumaric acid (pKa 3.02) etc., the acid that the material that the oxidisability such as chlorine that electrolysis produces are strong and these degree of ionization are big reacts, thereby the redox potential of electrolyte (ORP) and free available chlorine (ACC) concentration do not rise, and, even in case rise, when stopping applying electrolysis power, redox potential and free available chlorine concentration also can reduce rapidly, the problem of the electrolyte with sterilizing power can not be stably supplied with in existence, because of rather than preferred.
In the present invention, as organic acid, be 4 or during at least a kind of above organic acid when using above-mentioned acid disassociation index (pKa), reactive low with electrolyte, be difficult for causing the decline of redox potential and effective chlorine density, therefore can supply with stable electrolyte.
In addition, if acid disassociation index (pKa) be 4 or above organic acid, for example succinic acid, acetic acid, propionic acid among compare, the reactivity of acetic acid is high slightly, and succinic acid and propionic acid are much at one, all have the reactive low character with electrolyte.If other rerum natura of these two kinds of organic acids relatively, succinic acid does not almost have volatility at normal temperatures, and the volatility height of acetic acid and propionic acid is emitted foul smell in the use on-the-spot meeting of electrolyte, therefore when using in a large number as the sea sedge inorganic agent that uses under open condition, usability is relatively poor.On the other hand, although succinic acid has good character aspect the stability of electrolyte and the fixedness under the normal temperature, but it is not so good to the dissolubility of water, from this point, in preparation some inconvenience a little during as the stoste of the aqueous solution of electrolysis adjuvant.
Therefore, in the present invention, and then from viewpoints such as usability, preferably be principal component (in organic acid, account for 50 weight % or more than), and then also contain propionic acid and/or acetate with the succinic acid.Can supply with better electrolyte thus.
In the present invention, can directly be used natural sea-water by the solvent of electrolyte, also can further in natural sea-water, add the electrolyte ingredient such as salt, calcium chloride of Sq (1~10 weight %), also can use by salinity the artificial seawater that saline solution constituted identical in addition with seawater.
In addition, preferably above-mentioned pH value by electrolytic solution (stoste) is adjusted to 2~5 scope.The adjusting of this pH value can wait and regulate according to employed organic acid kind, usage amount, and with respect to the total amount of sea water solution, the concentration of acid such as above-mentioned organic acid is generally 0.01~0.5 weight % (about 0.00001~0.1mol).
If this pH value less than 2, the then chlorine (Cl of molecular state in the electrolyte 2) contain proportional rising, the danger that produces chlorine raises, and on the other hand, if pH value surpasses 5, then kills the algae bactericidal effect and descends, so be not preferred.
In the present invention, electrolyte obtains in the following way: be dissolved with contain above-mentioned acid disassociation index (pKa) be 4 or at least a organic acid of above organic acid and pH value be to put into the electrode of forming by anode and negative electrode in the sea water solution (by electrolyte) of 2~5 scope, to wherein feeding DC current, obtain electrolyte.In addition, from easily device being guarded the angle of management,, the no diaphragm type of barrier film is not set between negative and positive the two poles of the earth preferably as electrolysis mode.
In order more effectively to bring into play effect of the present invention, resulting electrolyte is as long as the pH value is acid, but preferred pH value is 3~5.If the pH value less than 3 of this electrolyte, the then chlorine (Cl of the molecular state of chlorine compound in the electrolyte 2) contain proportional rising, the danger that produces chlorine increases, on the other hand, if pH value above 5, the relatively poor hypochlorite ion (OCl of sterilizing power then -) ratio raise, can find that the algae bactericidal effect reduces extremely, be not preferred therefore.Therefore, preferred pH value is 3~5 scope, can prevent to produce pernicious gas in this pH scope, and the ratio of sterilization, hypochlorous acid (HOCl) that algae killing effect is high increases.
In addition, the redox potential (ORP) of employed electrolyte was so long as be expressed as the 1140mv or the above state of oxidation with the hydrogen electrode scaled value during sea sedge was handled, and demonstrating the characteristic that produces 1ppm or above free available chlorine concentration (ACC) gets final product, preferred redox potential (ORP) be 1150mv or more than, 1150~1220mv more preferably, effective chlorine density (ACC) be preferably 3ppm or more than, 3~15ppm more preferably.
In the present invention, for pH value, redox potential (ORP) state of the electrolyte that keeps being suitable for the above-mentioned scope of effective sea sedge in handling, preferably in the implementation process that sea sedge is handled, also continue complement lysis new acid acid solution with continue to apply the voltage (energising) that is used for electrolysis.Acid solution is preferably by being that index is replenished with the liquid-feeding pump of pH meter interlock, with the pH value, the continuation of energising is preferably by being that index is switched on the supply unit of residual chlorine meter interlock, with free available chlorine concentration, or by being that index is switched on the supply unit of oxidation-reduction potentiometer interlock, with the redox potential.
What in the present invention, employed sea sedge inorganic agent (liquid) was made up of the electrolyte of preparation under these conditions in treatment trough.By in filling the treatment trough of this electrolyte, carrying out impregnation process (infusion process, impregnation process), perhaps this electrolyte is spread on this breeds sea sedge (distribution method, scatter processing) and carry out the processing of sea sedge culturing sea sedge.
In these sea sedges are handled, the time of contact of electrolyte and sea sedge, the processing time of being, according to the characteristic of prepared electrolyte and as the difference of the assorted algae of processing object, pathogen and difference is preferably 1 second~1 minute, more preferably 5 seconds~30 seconds.
After in above-mentioned treatment trough, handling, put back to the sea sedge net in the seawater immediately and proceed common breed.
In the present invention, the electrolysis of above-mentioned organic acid sea water solution is to carry out in the electrolytic cell on being arranged on the sea sedge operation ship, and use circulating pump prepared electrolyte to be supplied in the treatment trough that is arranged on equally on the sea sedge operation ship, in this treatment trough, carry out the processing of sea sedge.Between electrolytic cell and the treatment trough, use circulating pump in running, to carry out the circulation of electrolyte all the time.Electrolytic cell and treatment trough can be in abutting connection with and incorporate structure also can be the diverse location that is separately positioned on operation ship, and the structure that connects by circulating pump, circulation pipe.

From the result of table 1 as can be seen, in the seawater that adds hydrochloric acid, when the pH value before the electrolysis is 3.00, do not find that the pH value because of electrolysis big variation takes place, can produce free available chlorine (ACC) well, the algae killing effect of diatoms is also high.But, the pH value be 4 or above by electrolyte in, pH rises bigger, the ACC concentration of generation is lower, the remarkable variation of diatom algae killing effect and bactericidal effect.This may be because hydrochloric acid also by electrolysis, and because a little less than the cushioning effect of hydrochloric acid, the altering a great deal of pH value, therefore, diatom kills algae and acts on and also dying down.
In contrast, from last table 2~4 as can be known, in succinic acid electrolyte, acetic acid electrolyte and propionic acid electrolyte, it is all very slight that the pH value is that the pH value in arbitrary electrolyte of 3~5 changes, and the generation of ACC in order.Therefore conclude and to generate the electrolyte that diatom kills algae and bactericidal effect height and stable performance.
