Abstract
The said sterilization process is that ClO2 or disinfectant with ClO2 component is used directly in preventing and controlling infectious diseases in aquariculture. The present invention sterilizes water and fresh food (including food organisms) for aquatic cultivation so as to control the pathogenic microbe amount in cultivation environment below certain level and to prevent the emergence and prevailing of infectious diseases, especially viral ones. It is safe and efficient.
Description
The present invention relates to a kind of sterilization process in the aquaculture, specifically use ClO
2(chlorine dioxide) or in order to ClO
2For the mixed type disinfectant of key component prevents and controls the generation of communicable disease and popular in aquaculture.
The disinfectant that general aquaculture is used can be divided into Halogen preparation (as: clorox, bleaching powder, bleaching powder, Iodophor, Babysafe, gansil or the like), peroxide (as: hydrogen peroxide, calper calcium peroxide, Peracetic acid, ozone etc.) and other chemical substance (as: potassium permanganate, copper sulphate, formaldehyde etc.) three major types by chemical feature; Also can be divided into oxidation formulation and non-oxide formulation two big classes according to chemical property, the former is as peroxide, Halogen preparation, potassium permanganate etc.; The latter such as copper sulphate, formaldehyde or the like.The application practice of laboratory research and aquaculture proves that these chemosterilants all can not effectively prevent and control communicable disease generation and popular in the aquaculture.Its reason is: non-oxide formulation disinfectant effect is relatively poor and toxic and side effect is big, so can not be used for preventing and control the generation of aquaculture communicable disease and popular; It is very big that the disinfection ability of oxidation formulation disinfectant is influenced by environment for use pH, in aquaculture production, the overwhelming majority all is more weak sterilizing ability, as clorox in weak acid environment (pH=6) sterilizing ability than big 80～100 times in the weakly alkaline environment (pH=9); In addition, after various oxidation formulation disinfectants are added in the breeding water body, most of (some or even all) is depleted in various organic matters, reducing inorganic thing and the ammonia nitrogen that contains in the water, and the amount of really using on the pathogenic microorganisms seldom or does not at all have, for example, in the distilled water that does not consume chlorine, add the free chlorine of 0.04mg/L, just can kill intestinal bacteria in a few minutes, but in natural water, add the free chlorine of 1-2mg/L sometimes, even higher can not killing intestinal bacteria, in culturing water, BOD, COD, NH
3-N, S
2-, Fe
2+Or the like pollution or electronation index content very high, to control various pathogenic microorganismss in the water body like this, the requirement of disinfectant is just very high very high, obviously, this extreme technology, do not implement meaning, no matter from aquatic aquaculture organism safety, still from all like this economically, moreover in aquaculture production, chlorination formulation disinfectant in the chlorine-containing agent and chlorizate thereof are very big to the toxic and side effect of aquatic aquaculture organism and whole breeding ecological environment, even consequently the available chlorine of low concentration also can make beneficial organism death in a large amount of breeding ecological environment, aquatic aquaculture organism grows and stagnates even death.It should be noted that, disinfectant practical in the aquaculture comprises that chlorination formulation disinfectant is relatively poor to the inactivating efficacy of virus, as drink water that (the drinking-water treatment process: flocculation-precipitation-filtration-sterilization) sterilization rate is up to 99.999%, but virus detects still and may be positive in the running water with the sterilization of 1-10mg/L available chlorine; And for example liquid chlorine inactivation of viruses test: the but deactivation not yet of pathology virus has all taken place in the free chlorine effect of 7mg/L 1 hour, host cell.So the disinfectant of commonly using is difficult to be used for the generation of communicate illness, especially viral infectious and popular in prevention and the control aquaculture.
European patent EP 93-544,950 and international monopoly WO95/18534 ClO
2The dipping method is treated or the communicable disease of control section aquaculture, has been proved to be very effective, and to the not influence of growing of aquatic aquaculture organism.But the dipping method only is treatment means rather than the effectively epidemic method of communicable disease in essence.
In addition, in the aquaculture in artificial feeding's fresh food in-situ processing and the breeding water body biology (comprising food organisms and non-food organisms) of natural propagation or artificial culture disinfect lack effective, nontoxic always and do not destroy its nutrient component and value, do not produce peculiar smell, disinfectant and using method easy to use, make that culturing the fresh food (comprising food organisms) that the main body per os ingests becomes important pathogeny portable object in the aquaculture.
Common disinfectants can not prevent and control generation of aquaculture communicable disease and popular shortcoming in the aquaculture in order to overcome in the present invention, has proposed a kind of ClO that directly uses in aquaculture
2Solution or in order to ClO
2Be the technology of the mixed type disinfectant disinfection of key component, communicable disease takes place and popular purpose in prevention and the control aquaculture to reach.
The present invention considers and realization: ClO like this
2Being optimal chemosterilant in the world today, is efficiently and safely disinfecting agent of IA level and food additives that The World Health Organization (WHO) and the World Food Programme (FAO) are recommended to the whole world.Compare ClO with the disinfectant of commonly using
2The disinfection characteristics be:
1. wide spectrum, fast, low toxicity (near nontoxic), efficient;
2. consumption is little and kill the virus (can force rate ozone not bad to the inhibition of disease caused by infectious water poison);
3. sterilizing ability is not subjected to the influence of water body pH (in the pH6-10 scope), ammonia nitrogen and organic concentration;
4. reaction has selectivity, ClO
2Not with ammonia nitrogen, most of amine, and organic matter alkane, alkene, alkynes, alcohol, reactive ketone just selectively with S
2-, Fe
2+, Mn
2+, CN
-Organic matter reaction etc. toxic side effects such as the secondary material of inorganic poison and phenol, chlorophenol, mercaptan, Zhongshu amine;
5. at ClO
2Disinfection simultaneously can not make the bioprotein sex change and lose existing nutrient component and value, simultaneously the aquatile cell is not had influence yet;
6. ClO
2Lasting effect is more of a specified duration, is about 10 times of chlorine;
7. chlorine dioxide is a kind of oxidant but is not chlorinating agent, thereby does not have the toxic and side effect of chlorinating agent.The communicable disease pathogene is bacterium, fungi, virus, parasite etc. in artificial aquaculture, and these pathogene mainly are present in water body and (comprise plankton and suspension in the water body.Growing pond substrate and other aquatile and their row pond things etc. carry pathogene, belonged to except that ingesting the per os propagation, because of must propagating so also include the water body class in to culturing main body by water body), in grow seedlings parent and the fresh food (comprising food organisms) etc., main per os of communicable disease and water body propagation.The present invention utilizes ClO
2Above-mentioned characteristic, in conjunction with the feature of aquaculture communicable disease outbreak of epidemic, taked the policy of putting prevention first, pathogene is killed or is suppressed in pathogeny or the communication media.
In view of aquatic aquaculture organism is just lived in the not high ecotope of requirement originally, therefore, in aquaculture production, also just prevented and controlled the generation of communicable disease in the aquaculture and popular as long as can control the level that exists of promptly controlling pathogenic microorganisms of growing, spread of pathogenic microorganisms in the breeding environment.Method is as follows: 1) kill at all or control on pathogeny: culture environment of aquatic products is maximum comprehensive pathogeny, be mainly reflected in non-aquaculture organism in breeding water body and the water body and the fresh food of feeding on, the parent of growing seedlings also is one of pathogeny, utilizes ClO
2The extremely strong effect of killing livestock, soak (pulverizing) artificial feeding's fresh food, can reach the purpose that the deactivation pathogenic microorganisms does not destroy fresh food nutritive value and composition simultaneously again, or with low concentration ClO
2Long-time breeding bait biology also can reach same purpose; To carrying the parent of growing seedlings of pathogeny, then survive the winter and nursery stage between, use ClO
2Control water body environment, processing parent, oophyte and fresh food to cultivate not the young in source in spite of illness, intercept the propagation of pathogeny; To the pathogenic microorganisms in the water body,,, can directly use ClO as filtration, precipitation etc. if breeding water carried out preliminary treatment
2Dissipation also can first pre-oxidation re-use ClO
2Dissipation, if do not carry out preliminary treatment, (purpose is can consume ClO earlier then can to carry out pre-oxidation artificially earlier
2The reducing substances oxidation, can influence ClO
2Water quality is eliminated, improved to the other factors of Disinfection Effect as far as possible, and the follow-up ClO that adds
2Then can directly act on pathogenic microorganisms, do economy, efficiently, safely like this) re-use ClO
2, then reach from the purpose of pathogeny control pathogenic microorganisms; 2) communication media of control pathogenic microorganisms: grow seedlings and mature stage between pre-disease prevention take place and take place disease just, control pathogenic microorganisms in the breeding water body mid-term, it is below horizontal and be unlikely to make and culture the main body morbidity and cause disaster or slow down and control epidemic situation to make it to be in morbidity, because ClO
2After the sterilization, remaining ClO
2And ClO
2 -The bacteriostasis that long duration is arranged, thus also can reach prevention and generation of control communicable disease and popular purpose.
