Description

この出願の発明は、水産系使用水の処理方法に関するものである。   The invention of this application relates to a method for treating fishery water.

魚病、中でもコイヘルペスに代表されるようなウイルス性の魚病は、養殖漁場等の水産系施設における飼育魚類の死を招くことから、業界において深刻な問題となっており、その対策法の確立が急がれている。   Fish diseases, especially viral fish diseases such as koi herpes, are a serious problem in the industry because they cause the death of domestic fish in aquaculture facilities such as aquaculture and fishing grounds. Establishment is urgent.

従来から、この対策として、例えば生体防御機能を利用した予防ワクチンの開発や同ワクチンを使用した治療方法の研究が行われている。また、ほとんどのウイルスが系外からの持ち込みであることから、例えば次亜塩素酸ナトリウム（ＮａＣｌＯ）やオゾン（Ｏ3）による使用水の消毒やウイルスフリーな魚類生育環境の設定コントロール（防疫）なども考えられている（例えば特許文献１，２参照）。 Conventionally, as countermeasures, for example, development of a preventive vaccine using a biological defense function and research on a treatment method using the vaccine have been performed. In addition, since most viruses are brought from outside the system, for example, disinfection of water using sodium hypochlorite (NaClO) or ozone (O 3 ), and control of the setting of a virus-free fish growth environment (prevention) (For example, refer to Patent Documents 1 and 2).

特開２００３−５２２７５号公報（明細書１−６頁、図１−４）Japanese Patent Laying-Open No. 2003-52275 (Specifications page 1-6, FIGS. 1-4) 特開平８−２３８２３号公報（明細書１−３頁、図１−２）JP-A-8-23823 (Specification page 1-3, FIG. 1-2)

しかし、予防ワクチンはウイルスの種類毎に開発する必要があり、接種の方法などの問題から経済的な問題まで相まって、いまだ開発に時間を要しているの現状である。   However, it is necessary to develop preventive vaccines for each type of virus. Currently, it takes time to develop, combined with problems such as inoculation methods and economic problems.

一方、次亜塩素酸ナトリウム（ＮａＣｌＯ）による消毒は、有機物存在下において付加
反応によりトリハロメタン等の発がん性物質を生成する恐れがある。また、アンモニア性窒素と反応して、クロラミンを生成し、同アンモニア性窒素濃度の約８倍の次亜塩素酸ナトリウムを消費するため、アンモニア性窒素含有水の場合、過剰の次亜塩素酸ナトリウムを注入する必要がある。 On the other hand, disinfection with sodium hypochlorite (NaClO) may generate carcinogenic substances such as trihalomethane by addition reaction in the presence of organic substances. In addition, it reacts with ammoniacal nitrogen to produce chloramine, which consumes about 8 times the sodium hypochlorite concentration of the ammoniacal nitrogen concentration. In the case of water containing ammoniacal nitrogen, excess sodium hypochlorite Need to be injected.

また、魚の生育環境の設定コントロールによる防疫方法は、水族館などの観賞魚の世界でこそ１５年程度の実績があるものの、経済効果が求められる養殖漁業の世界では、いまだ実績は不明である。   In addition, although the epidemic prevention method by setting and controlling the fish growth environment has a track record of about 15 years in the world of ornamental fish such as aquariums, the track record is still unknown in the world of aquaculture and fishery where economic effects are required.

本願発明は、このような現状に鑑み、有機物存在下においてもトリハロメタンを生成せず、アンモニア性窒素による濃度減少のない二酸化塩素を消毒剤として添加することによって、養殖漁場等の水産系施設における水産系使用水中のウイルス等の効果的な防疫（殺菌、減菌、不活化）を可能にした水産系使用水の処理方法を提供することを目的とするものである。   In view of such a current situation, the present invention does not produce trihalomethane even in the presence of organic matter, and adds chlorine dioxide that does not decrease in concentration due to ammonia nitrogen as a disinfectant, so that fisheries in aquaculture facilities such as aquaculture fisheries can be used. It is an object of the present invention to provide a method for treating fishery water that enables effective prevention (sterilization, sterilization, inactivation) of viruses and the like in water.

本願発明は、上記従来の問題を確実に解決し、その目的を達成するために、次のような課題解決手段を備えて構成されている。   The present invention is configured to include the following problem solving means in order to reliably solve the conventional problems and achieve the object.

（１） 第１の課題解決手段
この発明の第１の課題解決手段は、水産系使用水中に、消毒剤として二酸化塩素を添加して防疫処理するようにしたことを特徴としている。 (1) First Problem Solving Means The first problem solving means of the present invention is characterized in that chlorine dioxide is added as a disinfectant to aquatic system use water to perform a prevention treatment.

二酸化塩素（ＣｌＯ2）は、殺菌効果が高い消毒薬である。そして、非常に水に溶けやすい性質がある。 Chlorine dioxide (ClO 2 ) is a disinfectant with a high bactericidal effect. And it has the property of being very soluble in water.

したがって、水産系使用水中に、消毒剤として二酸化塩素（ＣｌＯ2）を魚類の生育に影響のない適切な濃度で添加すると、均一に溶け込んでウィルス等に対して極めて有効な殺菌、減菌、不活化作用が生じ、当該水産系使用水の効果的な再生を図ることができる。 Therefore, when chlorine dioxide (ClO 2 ) is added as a disinfectant at an appropriate concentration that does not affect the growth of fish, it will dissolve evenly and be extremely effective for sterilization, sterilization, An activation effect arises, and the effective reproduction of the fishery water can be achieved.

しかも、次亜塩素酸ナトリウムなどと異なって、有害なトリハロメタンを生成しない。   Moreover, unlike sodium hypochlorite, it does not produce harmful trihalomethanes.

したがって、２次汚染等の問題も生じない。   Therefore, problems such as secondary contamination do not occur.

また、アンモニア性窒素と反応しないため、使用水中にアンモニア性窒素が含有している場合にも、過剰注入の必要がない。   Moreover, since it does not react with ammonia nitrogen, there is no need for excessive injection even when ammonia nitrogen is contained in the water used.

（２） 第２の課題解決手段
この発明の第２の課題解決手段は、上記第１の課題解決手段の構成において、二酸化塩素は、電解法、化学法又は紫外線照射法のいずれか一つの方法により生成されるようになっていることを特徴としている。 (2) Second Problem Solving Means According to a second problem solving means of the present invention, in the configuration of the first problem solving means, chlorine dioxide is any one of an electrolytic method, a chemical method and an ultraviolet irradiation method. It is characterized by being generated by.

二酸化塩素を発生させる方法には、例えば電解法、化学法、紫外線照射法等の各種の方法があり、本願発明では、それらの各々の採用が可能である。   As a method for generating chlorine dioxide, there are various methods such as an electrolytic method, a chemical method, and an ultraviolet irradiation method, and each of them can be adopted in the present invention.

先ず電気分解による方法は、亜塩素酸ナトリウムを原料とし、電気分解することにより生成させることができ、アンモニア性窒素と反応せず、水に均一に溶け込むため、自由な濃度への調整が可能である。   First, the electrolysis method uses sodium chlorite as a raw material and can be generated by electrolysis. It does not react with ammoniacal nitrogen and dissolves uniformly in water, so it can be adjusted to a free concentration. is there.

したがって、例えば飼育水循環飼育方式や底面濾過方式では実現できないほどの高いレベルの水質を必要とする魚類の種苗生産場水槽、特に稚仔魚期の飼育用水槽などにおける使用水（減菌水）などにも適している。   Therefore, for example, the water used in the seedling production tanks for fish that require a water quality of a level that cannot be achieved by the breeding water circulation breeding system or the bottom filtration system, especially in the breeding tanks for larvae, etc. Is also suitable.

また、化学反応を利用する方法には、例えば塩素酸ナトリウム（ＮａＣｌＯ3）を硫酸（Ｈ2ＳＯ4）酸性下で還元する方法、亜塩素酸ナトリウム（ＮａＣｌＯ2）に酸を作用させる方法等の各種の方法があり、いずれも高い生成効率が得られる。 Examples of the method utilizing a chemical reaction include a method of reducing sodium chlorate (NaClO 3 ) under sulfuric acid (H 2 SO 4 ) acidity, a method of allowing an acid to act on sodium chlorite (NaClO 2 ), and the like. There are various methods, and all of them can achieve high production efficiency.

さらに、紫外線照射法の場合、例えば亜塩素酸ナトリウム（ＮａＣｌＯ2）を添加した使用水に対して、例えば紫外線ランプ等により紫外光を照射する。 Further, in the case of the ultraviolet irradiation method, for example, ultraviolet light is irradiated, for example, by an ultraviolet lamp or the like to water used to which sodium chlorite (NaClO 2 ) is added.

亜塩素酸ナトリウム（ＮａＣｌＯ2）を添加した使用水に紫外線を照射すると、当該紫外線によって使用水中の亜塩素酸ナトリウム（ＮａＣｌＯ2）が分解されて二酸化塩素（ＣｌＯ2）が発生し、亜塩素酸ナトリウムが低濃度でもウィルス等に対して特に有効な殺菌、減菌、不活化作用を発揮するようになり、当該水産系使用水の一層効果的な再生を図ることができる。 When the water used with sodium chlorite (NaClO 2 ) is irradiated with ultraviolet light, sodium chlorite (NaClO 2 ) in the water used is decomposed by the ultraviolet light to generate chlorine dioxide (ClO 2 ). Even when the concentration of sodium is low, particularly effective sterilization, sterilization, and inactivation action against viruses and the like can be achieved, and more effective regeneration of the fishery water can be achieved.

（３） 第３の課題解決手段
この発明の第３の課題解決手段は、上記第１又は第２の課題解決手段の構成において、水産系使用水が、観賞魚滅菌水、養殖用飼育水又は養殖用疾病治療水のいずれか一つであることを特徴としている。 (3) Third Problem Solving Means According to a third problem solving means of the present invention, in the configuration of the first or second problem solving means, the aquatic system use water is sterilized aquarium fish, aquaculture rearing water or It is characterized by being one of the disease treatment water for aquaculture.

上記二酸化塩素による防疫作用が有効となる水産系使用水としては種々のものが考えられるが、中でも観賞魚滅菌水、養殖用飼育水、養殖用疾病治療水等に対して特に有効である。   A variety of aquatic use waters that are effective for the prevention of epidemics by chlorine dioxide can be considered, and are particularly effective for ornamental fish sterilization water, aquaculture breeding water, aquaculture disease treatment water, and the like.

（４） 第４の課題解決手段
この発明の第４の課題解決手段は、上記第１，第２又は第３の課題解決手段の構成において、使用水中の二酸化塩素濃度が、０．０１ｍｇ／ｌから２．００ｍｇ／ｌの範囲であることを特徴としている。 (4) Fourth Problem Solving Means According to a fourth problem solving means of the present invention, in the configuration of the first, second or third problem solving means, the chlorine dioxide concentration in the used water is 0.01 mg / l. To 2.00 mg / l.

最適な使用水中の二酸化塩素濃度は、魚の種類やウィルス等の種類によって異なるが、その殺菌効果の高さを考えると、一般的に見て、０．１ｍｇ／ｌ〜２．００ｍｇ／ｌの極めて低い濃度範囲で十分に効果的であり、有効な殺菌効果を得ながら、しかも魚類の生育には全く影響を与えなくて済むようになる。   The optimum chlorine dioxide concentration in the water used varies depending on the type of fish, virus, etc., but considering the high bactericidal effect, it is generally 0.1 mg / l to 2.00 mg / l. It is sufficiently effective in a low concentration range, and it is possible to obtain an effective bactericidal effect while having no influence on the growth of fish.

以上の結果、本願発明の水産系使用水の処理方法によると、養殖漁場等の水産系施設において、ウィルス等の病原菌に対して有効な防疫（殺菌、減菌、不活化）を行ない、水産系使用水の効果的かつ低コストな再生を図ることができるようになる。   As a result of the above, according to the method for treating water used in the aquaculture system of the present invention, in aquaculture facilities such as aquaculture and fishing grounds, effective prevention (sterilization, sterilization, inactivation) against pathogenic bacteria such as viruses is carried out. Effective and low-cost regeneration of the water used can be achieved.

（最良の実施の形態）
以下、本願発明の最良の実施の形態に係る例えば養殖漁場等の水産系施設における水産系使用水の処理方法および同処理方法を実施する処理装置の構成について説明する。 (Best Embodiment)
Hereinafter, a method for treating aquatic use water in a fishery facility such as an aquaculture fishery according to the best mode of the present invention and a configuration of a treatment apparatus for carrying out the treatment method will be described.

先ずこの発明の最良の実施の形態に係る水産系使用水の処理方法および処理装置は、例えば図１に示すように、水産系使用水１ａを貯留した水産系使用水水槽１中の水産系使用水１ａ中に消毒剤として所定量の二酸化塩素（ＣｌＯ2）を添加して防疫（殺菌、減菌、不活化）処理するようにしている。 First, as shown in FIG. 1, for example, as shown in FIG. 1, a processing method and a processing apparatus for aquatic-system-use water according to the best embodiment of the present invention are used in aquaculture-system-use aquarium 1 that stores aquaculture-system-use water 1 a. A predetermined amount of chlorine dioxide (ClO 2 ) is added to the water 1a as a disinfectant to carry out an epidemic (sterilization, sterilization, inactivation) treatment.

二酸化塩素（ＣｌＯ2）の添加は、所定の添加装置２を用いてなされ、同添加装置２により二酸化塩素貯留部３に貯留されている二酸化塩素（ＣｌＯ2）を必要な時に必要な量だけ添加する。 Chlorine dioxide (ClO 2 ) is added using a predetermined addition device 2, and chlorine dioxide (ClO 2 ) stored in the chlorine dioxide storage unit 3 is added by the addition device 2 only when necessary. To do.

この二酸化塩素（ＣｌＯ2）の添加タイミングおよび添加量は、例えば所定のマイコンユニット８によって適切に制御される。 The addition timing and addition amount of chlorine dioxide (ClO 2 ) are appropriately controlled by, for example, a predetermined microcomputer unit 8.

二酸化塩素（ＣｌＯ2）は、上水の消毒にも使用が認められており、安全性が高い消毒薬である。 Chlorine dioxide (ClO 2 ) has been approved for disinfection of clean water and is a highly safe disinfectant.

そして、非常に水に溶けやすい。   And it is very easy to dissolve in water.

したがって、水産系使用水１ａ中に消毒剤として二酸化塩素（ＣｌＯ2）を添加すると、容易に溶け込んで均一に分布し、ウィルス等の魚の病原菌または一般細菌に対して、極めて有効な防疫（殺菌、減菌、不活化）作用が生じ、当該水産系使用水の適正な再生を図ることができる。 Therefore, when chlorine dioxide (ClO 2 ) is added as a disinfectant to the aquatic system use water 1a, it is easily dissolved and distributed evenly, and it is extremely effective against germs such as viruses or general bacteria. (Sterilization, inactivation) action occurs, and appropriate reproduction of the fishery water can be achieved.

また、すでに説明した従来の次亜塩素酸ナトリウム（ＮａＣｌＯ）などと異なって、発がん性のあるトリハロメタンなどを生成せず、使用水１ａ中のアンモニア性の窒素とも反応しにくい。   Moreover, unlike the conventional sodium hypochlorite (NaClO) etc. which were already demonstrated, it does not produce | generate carcinogenic trihalomethane etc. and does not react easily with the ammoniacal nitrogen in the use water 1a.

したがって、２次汚染等の問題も生じない。   Therefore, problems such as secondary contamination do not occur.

また、アンモニア性窒素と反応しないため、使用水中にアンモニア性窒素が含有している場合にも、過剰注入の必要がない。   Moreover, since it does not react with ammonia nitrogen, there is no need for excessive injection even when ammonia nitrogen is contained in the water used.

そして、上記使用水水槽１中の使用水１ａ中に添加される二酸化塩素（ＣｌＯ2）の濃度は、例えば０．１ｍｇ／ｌ〜２．００ｍｇ／ｌの低い範囲に設定して実施される。 The concentration of chlorine dioxide (ClO 2) added during use water 1a of the water used water bath 1 is performed by setting the lower range for example of 0.1mg / l~2.00mg / l.

最適な使用水中の二酸化塩素（ＣｌＯ2）の濃度は、魚の種類やウィルス等の種類によって異なるが、上記殺菌効果の高さを考えると、一般的に見て、０．１ｍｇ／ｌ〜２．００ｍｇ／ｌの極めて低い濃度範囲で十分に有効であり、有効な殺菌効果を得ながら、しかも魚類の生存には全く影響を与えなくて済むようになる。 The optimum concentration of chlorine dioxide (ClO 2 ) in the water used varies depending on the type of fish, virus, etc., but generally considering the high bactericidal effect, generally 0.1 mg / l to 2. It is sufficiently effective in the extremely low concentration range of 00 mg / l, and it is possible to obtain an effective bactericidal effect while having no influence on fish survival.

ところで、上記消毒剤としての二酸化塩素（ＣｌＯ2）は、電解法、化学法又は紫外線照射法等のいずれかの方法により生成される。 By the way, chlorine dioxide (ClO 2 ) as the disinfectant is produced by any method such as an electrolytic method, a chemical method, or an ultraviolet irradiation method.

先ず電気分解による方法は、亜塩素酸ナトリウムを原料とし、電気分解することにより生成させることができ、アンモニア性窒素と反応せず、水に均一に溶け込むため、自由な濃度への調整が可能である。   First, the electrolysis method uses sodium chlorite as a raw material and can be generated by electrolysis. It does not react with ammoniacal nitrogen and dissolves uniformly in water, so it can be adjusted to a free concentration. is there.

したがって、例えば飼育水循環飼育方式や底面濾過方式では実現できないほどの高いレベルの水質を必要とする魚類の種苗生産場水槽、特に稚仔魚期の飼育用水槽などにおける使用水（減菌水）などにも適している。   Therefore, for example, the water used in the seedling production tanks for fish that require a water quality of a level that cannot be achieved by the breeding water circulation breeding system or the bottom filtration system, especially in the breeding tanks for larvae, etc. Is also suitable.

また、化学反応を利用する方法には、例えば塩素酸ナトリウム（ＮａＣｌＯ3）を硫酸（Ｈ2ＳＯ4）酸性下で還元する方法、亜塩素酸ナトリウム（ＮａＣｌＯ2）に酸を作用させる方法等の各種の方法があり、いずれも高い生成効率が得られる。 Examples of the method utilizing a chemical reaction include a method of reducing sodium chlorate (NaClO 3 ) under sulfuric acid (H 2 SO 4 ) acidity, a method of allowing an acid to act on sodium chlorite (NaClO 2 ), and the like. There are various methods, and all of them can achieve high production efficiency.

さらに、紫外線照射法の場合、例えば亜塩素酸ナトリウム（ＮａＣｌＯ2）を添加した使用水に対して、例えば紫外線ランプ等により紫外光を照射する。すると、当該紫外光の自然分解作用によって二酸化塩素（ＣｌＯ2）が発生し、亜塩素酸ナトリウム（ＮａＣｌＯ2）自体の殺菌効果も相乗して、そのウィルス等に対する殺菌効果が大きく向上し、水産系使用水１ａの一層効果的な再生を図ることができる。 Further, in the case of the ultraviolet irradiation method, for example, ultraviolet light is irradiated, for example, by an ultraviolet lamp or the like to water used to which sodium chlorite (NaClO 2 ) is added. Then, chlorine dioxide (ClO 2 ) is generated by the natural decomposition action of the ultraviolet light, and the bactericidal effect of sodium chlorite (NaClO 2 ) itself is synergistically improved, so that the bactericidal effect against the virus is greatly improved. More effective regeneration of the used water 1a can be achieved.

亜塩素酸ナトリウム（ＮａＣｌＯ2）を添加した使用水に紫外線を照射すると、当該紫外線にによって使用水中の亜塩素酸ナトリウム（ＮａＣｌＯ2）が分解されて二酸化塩素（ＣｌＯ2）が発生し、亜塩素酸ナトリウムが低濃度でもウィルス等に対して特に有効な殺菌、減菌、不活化作用を発揮するようになり、当該水産系使用水の一層効果的な再生を図ることができる。 When the water used with sodium chlorite (NaClO 2 ) is irradiated with ultraviolet light, the ultraviolet light decomposes sodium chlorite (NaClO 2 ) in the water used to generate chlorine dioxide (ClO 2 ). Even when sodium acid is in a low concentration, it can exert particularly effective sterilization, sterilization, and inactivation actions against viruses and the like, and more effective regeneration of the water used in the fishery system can be achieved.

その場合、例えば上記図１の構成の二酸化塩素貯留部３を亜塩素酸ナトリウム貯留部に変えて、水産系使用水水槽１の水産系使用水１ａ中に直接亜塩素酸ナトリウム（ＮａＣｌＯ2）を添加し、同水産系使用水水槽１中に紫外線ランプ等で紫外光を照射する方法、また、そうではなく、一旦使用水供給ラインの前段側に所定の少容量の使用水貯留槽を設け、同使用水貯留槽に対して亜塩素酸ナトリウム（ＮａＣｌＯ2）を所定量添加することにより所定濃度以上の亜塩素酸ナトリウム濃溶液を形成しておいて、同濃溶液に紫外線ランプの紫外光を照射して二酸化塩素（ＣｌＯ2）を生成させ、その上で添加装置２を介して水産系使用水水槽１内の水産系使用水１ａ中に添加する方法などが任意に採用される。 In that case, for example, the chlorine dioxide storage part 3 having the configuration shown in FIG. 1 is changed to a sodium chlorite storage part, and sodium chlorite (NaClO 2 ) is directly added to the fishery system use water 1a of the fishery system use water tank 1. A method of adding and irradiating ultraviolet light with an ultraviolet lamp or the like in the fishery system use water tank 1, or, instead, once providing a use water storage tank of a predetermined small capacity on the front stage side of the use water supply line, By adding a predetermined amount of sodium chlorite (NaClO 2 ) to the same water storage tank, a concentrated sodium chlorite solution having a predetermined concentration or more is formed, and ultraviolet light from an ultraviolet lamp is applied to the concentrated solution. Irradiation produces chlorine dioxide (ClO 2 ), and then a method of adding it to the aquatic system use water 1a in the aquatic system use aquarium 1 via the addition device 2 is arbitrarily adopted.

亜塩素酸ナトリウム（ＮａＣｌＯ2）を添加した使用水に紫外光を照射すると、当該紫外光による自然分解によって当該使用水中に二酸化塩素（ＣｌＯ2）が発生する。そして、同二酸化塩素（ＣｌＯ2）は、上述のようにウィルス等に対して特に有効な殺菌作用を有し、水産系使用水の効果的な再生を図ることができる。 When the used water to which sodium chlorite (NaClO 2 ) is added is irradiated with ultraviolet light, chlorine dioxide (ClO 2 ) is generated in the used water by natural decomposition by the ultraviolet light. The chlorine dioxide (ClO 2 ) has a particularly effective bactericidal action against viruses and the like as described above, and can effectively recycle the water used in the fishery system.

しかし、紫外光照射による二酸化塩素（ＣｌＯ2）の発生効率を考えると、水量の多い水槽１内の水産系使用水中に亜塩素酸ナトリウム（ＮａＣｌＯ2）を添加してからよりも、高濃度の所定量の水溶液状態で、紫外光を照射する方が好ましく、そのようにして効率良く二酸化塩素（ＣｌＯ2）を発生させてから、水槽１内の水産系使用水１ａ中に添加する方が殺菌効果も高い。 However, considering the generation efficiency of chlorine dioxide (ClO 2 ) by irradiation with ultraviolet light, the concentration is higher than that after adding sodium chlorite (NaClO 2 ) to the aquatic system use water in the aquarium 1 with a large amount of water. It is preferable to irradiate with ultraviolet light in a predetermined amount of aqueous solution. Thus, chlorine dioxide (ClO 2 ) is efficiently generated and then added to the aquatic system use water 1a in the water tank 1 for sterilization. The effect is also high.

さらに、同亜塩素酸ナトリウム（ＮａＣｌＯ2）を分解させる紫外線発生手段としては、何も上記紫外線ランプ等の人工的な光源には限らない。 Further, the ultraviolet ray generating means for decomposing sodium chlorite (NaClO 2 ) is not limited to an artificial light source such as the ultraviolet lamp.

例えば特に、強い紫外光成分を有する太陽光を用いて分解させるようにしてもよい。そのようにすると、無駄な電力消費を招くことなく、より低コストで効率良く二酸化塩素（ＣｌＯ2）を生成させることができる。 For example, in particular, it may be decomposed using sunlight having a strong ultraviolet light component. By doing so, chlorine dioxide (ClO 2 ) can be efficiently generated at a lower cost without causing unnecessary power consumption.
