Abstract
Description
본 발명은 양어장용 수질개선제에 관한 것으로, 보다 상세하게는 양어장에 공급되는 먹이와 어류의 배설물의 부패로 인하여 발생되는 아질산이온(NO2-), 암모니아이온(NH4+), 황화수소(H2S) 등의 유해성분을 신속하고 안정하게 제거할 수 있는 양어장용 수질개선제에 관한 것이다.The present invention relates to a water quality improver for fish farms, and more particularly, nitrite ions (NO 2- ), ammonia ions (NH 4 +), hydrogen sulfide (H 2 ) caused by the decay of food and fish droppings supplied to fish farms The present invention relates to a water quality improving agent for fish farms capable of quickly and stably removing harmful components such as S).
일반적으로 양어장에는 어류의 먹이와 배설물이 축적될 수 밖에 없는 바, 시간이 경과함에 따라 먹이와 배설물이 부패됨으로 인하여 부영양화가 진행됨으로써, 악취가 발생되고 수질이 오염되어 어류가 집단 폐사되는 문제가 빈번하게 발생되고 있다.In general, fish farms are forced to accumulate food and excreta. As time passes, the food and excretion decay, resulting in eutrophication. It is happening.
즉, 양어장에서 어류를 양식하는 호지에 투여하는 어류의 먹이가 축적되고 부패가 진행됨에 따라 아질산이온(NO2-), 암모니아이온(NH4+), 황화수소(H2S)등 유해성분 및 악취가 발생되어 어류에게 스트레스를 주거나, 집단폐사를 시키게 되는 것이다.That is, as the food of fish administered to the ponds for fish farming in fish farms accumulates and decay progresses, harmful components such as nitrite ions (NO 2- ), ammonia ions (NH 4 +), hydrogen sulfide (H 2 S) and odors Is generated to stress the fish, or cause collective death.
이러한 어류의 집단폐사를 막고 수질을 개선시키기 위하여 화학약품이나 단순히 미생물제제 등을 사용하지만, 효과가 나타날때까직의 체류시간(holding time)이 약 15일 이상 경과 소요되어야 했으며, 유해성분의 처리능률도 50% 정도에 미치지 못하고 있는 실정이다.Chemicals or simply microbial agents are used to prevent the mass deaths of these fish and to improve the water quality. However, the holding time must be about 15 days or more until the effect is achieved. It is also less than 50%.
이를 어류의 먹이성분을 구체적으로 분석하여 상세히 설명하면, 일반적인 어류의 먹이 중 단백질 성분에 두개 또는 그이상의 아미노산(amino acid)이 아미드결합(amino bond)에 의해서 서로 결합{펩티드(peptide)결합}되어 있다.This will be described in detail by analyzing the food components of the fish in detail, two or more amino acids in the protein component of the general fish foods (peptide-bound) is bound to each other by an amide bond (amino bond) have.
이러한, 펩티드결합은 펩티드 체인(peptide chain)이 수소결합(hydrogen bond)에 의해서 helical form(나선형)으로 만들어져 있다.In such peptide bonds, peptide chains are formed in a helical form by hydrogen bonds.
단백질은 아미노산(amino acid)의 사이드 체인(side chain)은 양성(+)으로 하전된 기를 가지며, 다른 것은 음(-)으로 하전된 기를 가진다. 이들은 서로 결합을 이루어서 두개 또는 그이상의 단백질(protein)이 만들어진다. 이렇게 만들어진 단백질이 축양장의 먹이로 공급되어 섭취하고 남은 것들은 부패에 의해서 변패 또는 산화과정을 걸쳐 변질되는데, 전자는 황화수소이고, 후자는 아질산가스나 암모니아가스가 발생되어 수중에서 다른 물질을 만나 아질산염(salt)을 만든다.Proteins have a positively charged group on the side chain of amino acids, and a negatively charged group on the other. They combine with each other to produce two or more proteins. The protein thus produced is fed to the feedstock of the farm and the remaining ones are deteriorated by decay or oxidation due to decay. The former is hydrogen sulfide, and the latter generates nitrite gas or ammonia gas and meets other substances in the water. )
상기 아질산염이 수용성일때 강산성을 띄게 되며, 이러한 수용상태는 어류에게 치명적인 외상을 줄 수 있을 뿐만 아니라 어류를 폐사시킬 수 있다.When the nitrite is water-soluble, it has a strong acidity, and this state of acceptance may cause fatal trauma to the fish as well as kill the fish.
이를 방지하기 위하여 일부 양어장에서는 용도가 방부제(살균제)인 포르말린계(HCOH) 등을 사용하여 처방하는 경우도 있으나, 이 또한 수질오염을 효과적으로 개선시킬 수 없었으며, 특히 인체에 유해한 방부제 성분이 어류에 축적되는 폐단이 있었다.In order to prevent this, some fish farms may be prescribed by using a formalin-based (HCOH), which is a preservative (disinfectant), but this also could not effectively improve water pollution, especially preservatives harmful to humans There was an accumulation of lungs.
또한, 양어장에서는 부패로 인하여 유독한 황화수소를 제거하기 위하여 경운, 폭기(공기에 쬐임), 약제살포(석회, 점토), 복사 등의 구체적인 방법이 개량기술로서 실시되고 있다.In addition, in fish farms, specific methods such as tillage, aeration (air exposure), chemical spraying (lime, clay), radiation, etc. are implemented as an improvement technique to remove toxic hydrogen sulfide due to decay.
상기 경운은 저질의 표층을 경운기를 예항하여 강제적으로 교반, 반전, 확산시켜, 빈산소 혹은 무산소 상태에 있는 미분해 유기물을 물리적으로 산소와 접촉시키는 방법이고, 상기 폭기는 폭기는 해저에 공기를 강제적으로 송입시켜, 용존산소 농도를 높이는 방법이다.The tilling is a method of forcibly stirring, inverting, and diffusing a poor surface layer to cultivate a tiller, thereby physically contacting undecomposed organic matter in an oxygen-free or anoxic state with oxygen, and the aeration is forcing air to the seabed. It is a method of increasing the dissolved oxygen concentration by sending in.
상기 석회 발포는 생석회를 살포하여 PH를 알칼리 쪽으로 유지하고, 오염물질을 난용성 화합물로서 고정 제거하는 방법이고, 상기 점토 살포는 점토 광물(몬모릴로나이트계 점토로, 주성분은 SiO2, Al2O3)을 살포하고, 수중유기 현탁물을 응집 침전시키고 아울러 저질을 피복하는 방법이며, 상기 복사는 저질을 완전히 모래로 덮어 오염저질 표면과 수상을 차단하는 방법이다.The lime foaming is a method of spraying quicklime to maintain the pH toward alkali, and fixed removal of contaminants as a poorly soluble compound, the clay spraying is a clay mineral (montmorillonite-based clay, the main component is SiO 2 , Al 2 O 3 ) This method is to spray and to deposit and coagulate the organic suspension in water, and to cover the bottoms, and the radiation is a method of completely covering the bottoms with sand to block the contaminated surface and the water phase.
이상의 개량기술의 적용에 있어서는 부산되는 문제점(오염물질의 확산, 수역의 오염, 일시적인 생산 행위의 중지, 2차적으로 발생한 오니의 처리)이 있으며, 비용이 많이 소요되고 수질 개선작업이 복잡한 단점이 있었다.In the application of the above improvement technology, there are problems such as by-products (diffusion of pollutants, water pollution, temporary suspension of production activity, treatment of sludge generated second), and costly and complicated improvement of water quality. .
또한, 수질 및 저질환경의 개선을 실시하는데 있어, 석회 살포법은 가장 값싸고 유효한 방법으로 제시되고 있는데, 그 효과는 수질 및 저질환경을 약 알칼리성으로 유지함으로써 달성된다.In addition, in the improvement of the water quality and the low quality environment, the lime spreading method is proposed as the cheapest and effective method, and the effect is achieved by maintaining the water quality and the low quality environment to be slightly alkaline.
그러나, 석회계 개선제는 강알칼리이며, 물과의 반응에 의해 발열하는등의취급에 주의가 필요하다는 것, 탄산화 반응의 진행에 의해 PH 유지효과, 난용성 화합물 생성반응이 지속되지 않는다는 것과, 또 수역에 대하여 PH 변동요인이 많은 등의 문제점이 있었다.However, the lime-based improving agent is a strong alkali, which requires attention in handling such as exothermic heat by reaction with water, PH retention effect and poorly water-soluble compound formation reaction are not sustained by the progress of carbonation reaction, There were problems such as a large number of PH variability factors.
따라서, 수질 및 저질 개선을 위하여, 환경이나 작업자에 대하여 안전성이 보장되어야 할 뿐만 아니라 어류에 유해성분이 축적되지 않아야 하며, 특히 사용이 쉽고 비용이 저렴한 개선제의 개발이 시급한 실정이다.Therefore, in order to improve water quality and quality, not only safety should be guaranteed for the environment or workers, but harmful components should not accumulate in fish, and in particular, it is urgent to develop an improvement agent that is easy to use and inexpensive.
본 발명은 상기한 제반 문제점을 해결하기 위해 창안된 것으로서, 본 발명의 목적은 수질개선제로서 탄산나트륨과 혐·호기성 미생물을 혼합 조성하여 수질을 오염시키는 아질산이온을 효과적으로 제거하고, 혐·호기성 미생물(유산균, 효모, 광합성세균등)이 부분적으로 발효되어 유기산과 이산화탄소(CO2)가스로 처리되어지면서 유해가스의 발생을 방지함으로써 양어장의 수질을 개선시키는데 그 목적이 있다.The present invention was devised to solve the above-mentioned problems, and an object of the present invention is to mix sodium carbonate and anaerobic and aerobic microorganisms as a water-improving agent to effectively remove nitrite ions polluting water, and to anaerobic and aerobic microorganisms (lactic acid bacteria). , Yeast, photosynthetic bacteria, etc.) are partially fermented and treated with organic acids and carbon dioxide (CO 2 ) gas to prevent the generation of harmful gases to improve the quality of fish farms.
본 발명의 또 다른 목적은, 수질의 PH에 따라 적절하게 중화할 수 있도록 수질개선제를 선택적으로 투여하고, 수질에 함유된 아질산이온과 암모니아이온의 함유량에 따라 계면활성제를 선택적으로 첨가하여 반응속도를 향상시킴으로써, 유해성분의 처리시간이 지연됨에 따른 어류의 집단폐사를 미연에 방지하는데 있다.Another object of the present invention is to selectively administer a water improver to properly neutralize according to the pH of the water, and selectively add a surfactant according to the content of nitrite and ammonia ions in the water to increase the reaction rate. By improving, it is possible to prevent the collective death of fish due to the delayed treatment time of harmful components.
상기의 목적을 달성하기 위한 본 발명의 구성은, 양어장용 수질을 정화하기 위해 투여하는 수질개선제에 있어서, 탄산나트륨 50∼97중량%에 미생물3∼50중량%로 혼합 조성된 것을 특징으로 한다.The constitution of the present invention for achieving the above object is characterized in that the water-improvement agent administered to purify the water quality for fish farms is mixed composition of 50 to 97% by weight sodium carbonate to 3 to 50% by weight of microorganisms.
또한 바람직하게는, 양어장용 수질을 정화하고 암모니아 이온을 제거하기 위해 투여하는 수질개선제에 있어서, 아세트산 1∼15중량%에 미생물 85∼99중량%로 혼합 조성된 것을 특징으로 한다.Also preferably, the water improver administered to purify the water quality for fish farms and remove ammonia ions is characterized in that 1 to 15% by weight of acetic acid is mixed with 85 to 99% by weight of microorganisms.
이하, 본 발명의 바람직한 실시예를 들어 상세히 설명하기로 한다.Hereinafter, a preferred embodiment of the present invention will be described in detail.
본 발명의 일실시예로서 양어장용 수질개선제는, 탄산나트륨 50∼97중량%에 미생물 3∼50중량%로 혼합 조성된다.As an embodiment of the present invention, the water quality improving agent for fish farms is mixed with 50 to 97% by weight of sodium carbonate at 3 to 50% by weight of microorganisms.
상기 탄산나트륨은 양어장의 수질에서 발생되는 아질산이온을 신속하고 안정하게 제거하기 위한 주요성분으로서, 탄산나트륨의 함유비율이 50중량% 보다 적은 경우에는 수질에서의 PH 유지효과가 효율적으로 달성되지 않고, 수질개선제의 투입량을 증가시킬 필요가 있어 바람직하지 않다. 따라서, 탄산나트륨은 50중랑% 이상이 혼합되는 것이 바람직하고, 더욱이 50∼97중량%의 범위로 혼합되는 것이 바람직하다.The sodium carbonate is a main component for quickly and stably removing nitrite ions generated in the water quality of fish farms. When the content of sodium carbonate is less than 50% by weight, the PH retention effect in the water quality is not efficiently achieved. It is not desirable to increase the dosage of. Therefore, it is preferable that 50 weight% or more of sodium carbonate is mixed, and also it is preferable to mix in 50 to 97 weight% of range.
또한, 본 발명의 탄산나트륨은 알칼리성이고 수중에서 붕괴되어 분산 용해됨으로써 석회계에서 볼 수 있는 탄산화 반응의 진행에 의한 반응속도가 느리거나 효과가 떨어지는 현상은 발생되지 않는다.In addition, the sodium carbonate of the present invention is alkaline and disintegrates and dissolves in water, so that the reaction rate due to the progress of the carbonation reaction seen in the lime system is slow or the effect is not degraded.
여기서, 상기 탄산나트륨의 효능을 보완할 수 있도록 상기 탄산나트륨과 미생물의 혼합 조성물 총 중량 대비 수산화나트륨 2∼10중량%를 더 혼합하여 본 발명의 수질개선제를 완성할 수도 있다.Here, the water-improving agent of the present invention may be completed by further mixing 2-10% by weight of sodium hydroxide with respect to the total weight of the mixed composition of sodium carbonate and microorganism so as to supplement the effect of the sodium carbonate.
상기 미생물은, 혐·호기성 미생물을 사용하여 지속적으로 확대 배양되어 수질의 정화작용을 지속적으로 처리하여 수질개선을 향상시키기 위해 혼합되는 것으로, 본 발명에서는 효모균(yeast), 유산균(lactobacillus), 광합성세균(photosynthetic microbe) 중에 어느 하나 또는 하나 이상이 선택되는 것이 바람직하다.The microorganism is continuously expanded and cultured using anaerobic / aerobic microorganisms and is mixed to improve water quality by continuously treating the purification of water quality, and in the present invention, yeast, lactobacillus, and photosynthetic bacteria. It is preferable that any one or more than one (photosynthetic microbe) is selected.
상기 미생물은 양어장의 수중에 투입되면 암모니화성 작용(유기물을 분해하여 암모니아를 생성)하는 특성이 있는 것으로, 그 세부적인 특성 및 생균수는 아래 [표 1]과 같다.The microorganisms are characterized by having an ammoxidative action (decomposing organic matter to generate ammonia) when introduced into the fish farm, and their detailed characteristics and viable cell counts are shown in Table 1 below.
상기 양어장용 수질개선제 가용성 분말로 제조됨에 따라 양어장의 수중에 투입했을 때 용해속도가 다소 저하되는 경향이 다양한 실험 결과를 통해 확인할 수 있었던 바, 상기 수질개선제의 물리적인 성질을 개선시켜 용해속도를 빠르게 하고 정화작용을 촉진시킬 수 있도록 상기 탄산나트륨과 미생물의 혼합 조성물 총 중량 대비 계면활성제 0.01∼1중량%를 더 혼합하는 것이 바람직할 것이다.As the water quality improver for the fish farm is made of soluble powder, the dissolution rate tends to decrease somewhat when added to the water of the fish farm, and can be confirmed through various experimental results. It may be desirable to further mix 0.01 to 1% by weight of surfactant with respect to the total weight of the mixed composition of sodium carbonate and microorganism so as to promote the purification.
여기서, 상기 계면활성제는 알칼리금속염 또는 알칼리토금속염 중에 선택하여 혼합하며, 바람직하게는 무취이면서 PH완충제(buffer)역할을 할 수 있는 칼륨염을 사용하게 된다.Here, the surfactant is selected from the alkali metal salts or alkaline earth metal salts and mixed, preferably using a potassium salt which is odorless and can act as a buffer buffer (buffer).
본 발명의 양어장용 수질개선제의 다른 실시예로서, 상기 탄산나트륨과 미생물의 혼합 조성된 수질개선제를 과다 투여하거나, 암모니아이온(NH4+)을 제거하여 양어장의 수질을 정화하기 위하여 아세트산 1∼15중량%에 미생물 85∼99중량%로 혼합 조성된 것을 사용한다.As another embodiment of the water quality improver for fish farming of the present invention, acetic acid 1 to 15% by weight in order to purify the water quality of the fish farm by overdosing the water quality improver of the mixed composition of sodium carbonate and microorganisms, or remove ammonia ion (NH 4 +) A mixture of 85 to 99% by weight of microorganisms is used.
상기 미생물은 효모균(yeast), 유산균(lactobacillus), 광합성세균(photosynthetic microbe) 중에 어느 하나 또는 하나 이상을 선택하여 사용한다.The microorganism is selected from one or more of yeast, lactobacillus, photosynthetic microbe.
상기 아세트산(acetic acid, CH3COOH)은 양어장에 투입하기 위해 식용 아세트산을 사용하게 되며, 양어장의 수질에 함유된 암모니아성 질소량을 측정하여 적정량의 상기 아세트산을 투여하여 중화하게 된다.The acetic acid (acetic acid, CH 3 COOH) is to use the edible acetic acid to enter the fish farm, by measuring the amount of ammonia nitrogen contained in the water quality of the fish farm is neutralized by administering the appropriate amount of acetic acid.
이를 호지(湖池) 내에 투여되는 어류의 먹이에 함유된 성분의 반응에 의해 설명하면, 어류 먹이의 대부분이 전분(녹말가루)과 탄수화물로 이루어져 있고, 또한 먹이 중에 함유되어 있는 단백질 성분에 두개 또는 그 이상의 아미노산(amino acid)이 아미드결합(amide bond)에 의해 서로 결합되어 있는 물질인 펩티드(peptide)가 존재하는 것으로, 상기 펩티드 결합구조는 ""으로 이루어진다.This is explained by the reaction of the components in the food of fish administered in ponds. Most of the fish food consists of starch and carbohydrates. Peptide, which is a substance in which more amino acids are bonded to each other by an amide bond, is present. Is made.
여기서, 단백질은 분해하여 아미노산(amino acid)이 알파-아미노산(α- amino acid)과 AHA(α- hydroxy acid)로 변하는 산화반응으로 알파-아미노 그룹(α- amino group)이 제거되는데 이 반응을 말한다. 이것은 단백질이 분해되는첫 단계이다. 또한 상기 반응은 두단계로 일어나는데 첫째는 탈수소(-H2) 반응이고, 둘째는 암모니아(-NH3)를 잃게되는 가수반응(+H2O)으로 나눌 수 있다.Here, the protein is decomposed to remove the alpha-amino group by an oxidation reaction in which the amino acid is converted into alpha-amino acid and AHA (α-hydroxy acid). Say. This is the first step in breaking down proteins. In addition, the reaction takes place in two stages, the first is a dehydrogenation (-H 2 ) reaction, the second can be divided into a hydrolysis reaction (+ H 2 O) to lose ammonia (-NH 3 ).
상기 반응식에서처럼 암모니아(ammonia)는 아미노산(amino acid)으로 부터 떨어지며, 케토산(keto acid), 즉 옥살아세트산(oxaloacetic acid), 케토글루타릭산(ketohlutaric acid)등이 된다.As in the above scheme, ammonia is separated from amino acid, and is keto acid, ie oxaloacetic acid, ketohlutaric acid, or the like.
따라서 아미노산의 반응은 여러 가지가 존재하지만 본 발명에 관계되는 항목만 기재한다.Therefore, there are many reactions of amino acids, but only the items related to the present invention are described.
(1) 산, 염기와 염을 형성한다(1) to form salts with acids, bases
(2) HNO₂에 의하여 질소가스(N2) 발생(van slyke)법(2) Nitrogen gas (N 2 ) generation by HNO₂ (van slyke) method
(3) 포름알데히드(포르말린 HCOH) -NH₂가 mask된다. (sorensen)(3) Formaldehyde (formalin HCOH) -NH2 is masked. (sorensen)
(4) 아세트산(CH3COOH)에 의하여 acetyation된다(4) acetyation with acetic acid (CH 3 COOH)
(5) 온도, PH, 무기이온 에 의하여 변성된다.(5) Denatured by temperature, PH and inorganic ions.
상기 아미노산 반응 중 (1),(5)항을 이용하여 수질 오염 상태를 측정 검사하고 그 결과에 따라서 산성과 염기성을 적절하게 처방한다.(1) and (5) of the amino acid reaction are used to measure and examine the state of water contamination, and accordingly, the acidity and basicity are appropriately prescribed.
즉, PH가 산성이면 염기성 제품의 나트륨이온 등을 첨가하고, PH가 염기성이면 산성 제품의 아세트산(H+)등 첨가하여 수질을 개선 또는 정화한다.That is, if pH is acidic, sodium ions and the like of a basic product are added, and if pH is basic, acetic acid (H +) and the like of an acidic product is added to improve or purify the water quality.
다시 말하면, PH가 산성이면, 상기 수질개선제인 탄산나트륨과 미생물 혼합물질을 투여함으로써 Na+ 등의 알카리 금속이 염으로 처리되고, PH가 염기성(알카리)이면, 본 발명의 다른 실시예인 상기 아세트산과 미생물 혼합물질을 투여하여 수질을 중성(PH7)으로 처리함으로써 어류의 스트레스나 외상을 벗어날 수 있게 되는 것이다.In other words, when the pH is acidic, alkali metals such as Na + are treated with salts by administering sodium carbonate and the microorganism mixture, which is the water improving agent, and when the pH is basic (alkali), the acetic acid and microorganisms mixed with the other embodiments of the present invention By administering the substance, the water quality is treated neutrally (PH7) to escape fish stress or trauma.
본 발명의 수질개선제는 가용성 분말로서 물리적 성질을 개선시키기 위해 표면활성 혼합물(계면활성제)과 혼합되어 있기 때문에 수질에 쉽게 용해되어 빠른 효과를 볼 수 있게 되며, 상기 수질개선제는 고형 분말로 된 각 성분을 특수한 입도에 맞는 제품을 선정하여 혼합 및 분쇄하여 상기 혐·호기성 미생물 분말을 혼합 후 냉각함으로써 제조된다.Since the water quality improving agent of the present invention is a soluble powder and is mixed with a surface active mixture (surfactant) to improve physical properties, it is easily dissolved in water quality so that a quick effect can be obtained, and the water quality improving agent is a solid powder. It is prepared by mixing and pulverizing a product suitable for a particular particle size by mixing and cooling the anaerobic, aerobic microbial powder.
이하에서는, 상기와 같이 구성된 본 발명을 바람직한 실험조건을 선정하여 구체적인 실시예와 비교예를 참조하여 상세히 설명하기로 한다.Hereinafter, the present invention configured as described above will be described in detail with reference to specific examples and comparative examples by selecting preferred experimental conditions.
[실험조건][Experimental Conditions]
(가) 실험장소 : 양어장(민물장어)(A) Experimental place: Fish farm (freshwater eel)
(나) 호지용량(양어장) : 물 400,000kg(400톤)을 저수할 수 있는 용량(B) Pond capacity (fish farm): Capacity to store 400,000kg (400 tons) of water
(다) 수질개선제 투여량 계산(호지 내의 아질산이온 측정 검사치가 10ppm일 경우)(C) Calculation of the dose of water improver (when the nitrite ion measurement test in the pond is 10 ppm)
400,000kg(호지용량) × 0.00001(아질산이온 10ppm) = 4kg400,000kg (Horse capacity) × 0.00001 (10 ppm nitrite ion) = 4kg
본 발명의 수질개선제는 100% 농도이므로, 상기 수질개선제 투여량은 호지내의 물의 용량에 아질산이온의 측정값을 곱하면 호지 내의 아질산이온을 제거하기 위한 투여량이 산출된다.Since the water improver of the present invention is 100% concentration, the water improver dose is multiplied by the measured value of nitrite ions by the dose of water in the pond to calculate the dose for removing nitrite ions in the pond.
(라) 수질개선제 용해방법(D) Dissolution method of water quality improver
20ℓ의 용기에 호지 내의 물을 15ℓ정도 투입하고 (다)항에서 계산된 수질개선제를 평량하여 용해시킨 후, 양어장의 수차가 가동되는 부분, 즉 물이 흐르는 곳에 흘려보낸다.15 liters of water in ponds is poured into a 20-liter container, and the water-improving agent calculated in paragraph (c) is weighed and dissolved, and then flowed to the part where the aberration of the fish farm operates, that is, where water flows.
(마) 상기 수질개선제는 탄산나트륨 50∼97중량%에 효모균, 유산균, 광합성세균이 혼합된 미생물을 3∼50중량%를 혼합 조성된 것이고, 호지 내에 함유된 암모니아성 질소가 10ppm이상일 경우에 사용되는 수질개선제는 아세트산 1∼15중량%에 효모균, 유산균, 광합성세균이 혼합된 미생물을 85∼99중량%를 혼합 조성되어 중화제로서 사용하게 되며, 반응속도를 향상시키기 위해 상기 수질개선제인 탄산나트륨과 미생물의 혼합 조성물 총 중량 대비 계면활성제(칼륨염) 0.01∼1중량%를 선택적으로 호지 내에 투입하게 된다.(E) The water-enhancing agent is a mixture of 50 to 97% by weight sodium carbonate and 3 to 50% by weight of microorganisms in which yeast, lactic acid bacteria and photosynthetic bacteria are mixed, and used when the ammonia nitrogen contained in ponds is 10 ppm or more. The water quality improver is used as a neutralizing agent by mixing 85 to 99% by weight of microorganisms in which yeasts, lactic acid bacteria and photosynthetic bacteria are mixed with acetic acid in 1-15% by weight, to improve the reaction rate of sodium carbonate and microorganisms. 0.01 to 1% by weight of surfactant (potassium salt) relative to the total weight of the mixed composition is optionally added to the pond.
(실시예 1)(Example 1)
호지 내(호지용량 400톤)의 아질산이온 함량이 10ppm이고 암모니아성 질소가 5ppm인 양어장에 수질개선제 4kg을 용해한 것을 투여하여 12시간 간격으로 Nitro test(NO2시약)로 측정하였으며, 호지 내에 아질산이온의 제거율(처리능률)의 측정 결과는 아래 [표 2] 및 [표 3]과 같다.A nitrite ion content of 10 ppm in a pond (400 tons pond capacity) and a fish farm containing 4 kg of ammonium nitrogen was dissolved in 4 kg of water improver was measured by Nitro test (NO 2 reagent) at 12-hour intervals. Measurement results of the removal rate (treatment efficiency) of are shown in [Table 2] and [Table 3] below.
상기 실시예 1에 따른 수질개선제 중 탄산나트륨과 아질산이온 및 암모니아성 질소는 아래와 같은 반응에 의해 아질산이온과 암모니아성 질소를 안정하게 제거하게 된다.Sodium carbonate, nitrite ions and ammonia nitrogen in the water improver according to Example 1 are to stably remove the nitrite ion and ammonia nitrogen by the following reaction.
또한, 호지 내에 투여된 어류의 먹이로부터 발생되는 악취는 상기 수질개선제의 성분인 미생물 중 광합성세균에 의해 제거되고, 기타 먹이분은 효모와 유산균으로 발효되어 유해성분이 발생하지 않으며, 미생물의 질화작용으로 호지 내에는 이산화탄소(CO2) 가스가 발생되었다.In addition, the odor generated from the food of the fish administered in the pond is removed by photosynthetic bacteria among the microorganisms of the water-improving agent, and other food components are fermented into yeast and lactic acid bacteria, and harmful ingredients do not occur, Carbon dioxide (CO 2 ) gas was generated in the pond.
(실시예 2)(Example 2)
호지 내(호지용량 400톤)의 아질산이온 함량이 40ppm이고 암모니아성 질소가 10ppm인 양어장에 수질개선제 16kg을 용해한 것을 투여하여 12시간 간격으로 Nitro test(NO2시약)로 측정하였으며, 호지 내에 아질산이온의 제거율(처리능률)의 측정 결과는 아래 [표 4] 및 [표 5]와 같다.In the pond (400 tons of pond capacity), nitrite ion content of 40 ppm and 10 ppm of ammonia nitrogen was dissolved in 16 kg of water-improving agent, which was measured by Nitro test (NO 2 reagent) at 12-hour intervals. Measurement results of the removal rate (treatment efficiency) of are shown in [Table 4] and [Table 5] below.
상기 실시예 1 및 2에서 실험한 결과와 같이, 본 발명의 수질개선제는 양어장 호지 내에서 유해 이온(아질산이온, 암모니아이온, 황화수소)이 발생 할 때, 예를 들어 아질산이온(NO2-)이 10ppm이상 함유될 때 수질 개선 및 정화하기 위하여 사용되며, 바람직하게는 아질산이온이 10ppm∼40ppm의 범위에서 수질개선 및 정화효과가 좋았음을 확인할 수 있었다.As a result of the experiments in Examples 1 and 2, the water-improving agent of the present invention, for example, when harmful ions (nitrite ions, ammonia ions, hydrogen sulfide) occurs in the ponds of fish farms, for example, nitrite ions (NO 2- ) It is used to improve and purify the water quality when contained in more than 10ppm, preferably nitrite ion was confirmed that the water quality improvement and purification effect was good in the range of 10ppm to 40ppm.
또한, 아질산이온이 40ppm 이상은 수질개선제를 1회에 투여할 경우에는 처리시간이 많이 소요되었음을 확인할 수 있었으며, 농도에 따라 투여 횟수를 늘려 일정 시간 간격으로 투여하거나, 반응속도를 향상시키기 위하여 상기 계면활성제(칼륨염)를 함께 투여하게 되면, 상기 실시예 1 및 2와 유사한 결과를 얻을 수 있었다.In addition, when the nitrite ion is 40ppm or more when the water treatment agent is administered at a time, it was confirmed that a lot of processing time was required, and the administration time was increased at regular intervals by increasing the number of administrations according to the concentration, or the interface to improve the reaction rate. When the active agent (potassium salt) was administered together, similar results to those of Examples 1 and 2 were obtained.
한편, 호지 내의 암모니아성 질소가 10ppm 이상일 경우에는 수질의 PH가 염기성(알칼리)을 띄게 되고, 상기 수질개선제의 반응속도가 지연되는 현상이 발생되었는데, 이를 방지하기 위하여 암모니아성 질소량을 측정하여 그에 해당하는 중화제로서 아세트산과 미생물을 혼합조성된 것을 투여하여 중화시킬 필요가 있었다.On the other hand, when the ammonia nitrogen in the pond is more than 10ppm, the pH of the water is basic (alkali), the reaction rate of the water improver occurred, the phenomenon occurred, in order to prevent this by measuring the amount of ammonia nitrogen It was necessary to neutralize by administering a mixture of acetic acid and microorganism as a neutralizing agent.
바람직하게는 암모니아성 질소가 10ppm이하로 조정한 후 상기 수질개선제를 투여하는 것이 효과적이었다.Preferably, it was effective to administer the water-quality improving agent after adjusting the ammonia nitrogen to 10 ppm or less.
(비교예)(Comparative Example)
종래의 수질개선제로서 미국에서 출시된 박테리아제품인 아메박 N-N(Amerbac-N-N)을 본 발명의 상기 실시예 1과 동일한 조건에서 호지 내에 투입하였다.Amebac N-N (Amerbac-N-N), a bacterial product released in the United States as a conventional water quality improver, was introduced into ponds under the same conditions as in Example 1 of the present invention.
여기서, 상기 아메박 N-N의 주성분은 암모니아성 질소이온, 아질산이온을 산화시킨 박테리아이며, 아질산이온(NO2-)과 NH3이온의 분해제로 사용되는 것이다.Here, the main component of Amebac NN is a bacterium that oxidizes ammonia nitrogen ions and nitrite ions, and is used as a decomposition agent of nitrite ions (NO 2 −) and NH 3 ions.
호지 내(호지용량 400톤)의 아질산이온 함량이 10ppm이고 암모니아성 질소가 5ppm인 양어장에 제1방법인 살포법으로 아메박 N-N을 4kg, 7kg, 10kg으로 하여 각각 투입하거나, 제2방법인 경구투여법으로 아메박 N-N을 사료의 중량 대비 0.5중량%로 혼합하여 투입하였다.In the pond (400 tons of pond), nitrite ion content of 10ppm and ammonia nitrogen of 5ppm is used as the first method of spraying Amebac NN into 4kg, 7kg and 10kg, respectively. As a dosage method, Amebac NN was added by mixing 0.5% by weight based on the weight of the feed.
상기 제1/2방법으로 종래의 아메박 N-N을 호지 내에 투입하여 실험한 결과, 제1방법인 살포법은 살포량에 관계없이 효과가 거의 없었으며, 제 2방법인 경구투여법은 15일 경과시 30.2%, 20일 경과시 50.2%의 아질산이온(NO2-)을 제거할 수 있었다.As a result of experimenting by inserting conventional Amebac NN into the pond by the first method, the first method of spraying had almost no effect regardless of the spraying amount, and the second method of oral administration was 15 days later. After 3 days and 5 days, 50.2% of nitrite ions (NO 2 −) could be removed.
상기 비교예를 상기 실시예 1과 비교하여 볼 때, 본 발명의 수질개선제가 아질산이온(NO2-)의 처리능률이 탁월하였을 뿐만 아니라 신속하게 처리되었음을 확인할 수 있었다.When comparing the Comparative Example with Example 1, it was confirmed that the water treatment improver of the present invention not only was excellent in the treatment efficiency of nitrite ions (NO 2- ) but also was quickly treated.
또한, 본 발명의 수질개선제는 수질의 PH가 산성이거나 염기성(알칼리)일 경우에 각각 탄산나트륨과 미생물 혼합물 또는 중화제로서 아세트산과 미생물 혼합물을 적절하게 투여할 수 있고, 특히 혐·호기성 미생물이 혼합되어 호지 내에서 지속적으로 확대 배양되어 수질의 정화작용을 지속적으로 처리하여 수질개선을 향상시킬 수 있으며, 계면활성제를 선택적으로 첨가하여 반응속도를 향상시킬 수 있는 것으로, 수질개선제에 있어서 매우 유용한 발명이라 할 것이다.In addition, the water quality improving agent of the present invention can properly administer acetic acid and microbial mixtures as sodium carbonate and microbial mixtures or neutralizers, respectively, when the pH of the water is acidic or basic (alkali). Continuously expanded and cultured in the water to improve the water quality by continuously treating the purification process, and by selectively adding a surfactant to improve the reaction rate, it will be a very useful invention in water quality improvement agent .
상술한 바와 같이 본 발명에 의하면, 수질개선제가 화학성분(탄산나트륨, 아세트산)과 혐·호기성 미생물을 혼합 조성되어 화학성분은 수질에 함유된 아질산이온(NO2-)을 신속하고 안정하게 제거할 수 있고, 미생물은 호지 내에 지속적으로 확대 배양되면서 수질을 정화시킬 수 있어 양어장의 수질을 효과적으로 개선시킬 수 있는 장점이 있다.As described above, according to the present invention, the water improver is a mixture of a chemical component (sodium carbonate and acetic acid) and an anaerobic / aerobic microorganism, so that the chemical component can quickly and stably remove nitrite ions (NO 2 −) contained in the water. In addition, the microorganisms can purify the water quality while continuously expanding the culture in ponds, there is an advantage that can effectively improve the water quality of the fish farm.
또한, 수질의 PH에 따라 적절하게 중화하여 수질개선제를 투여하고, 수질에 함유된 아질산이온(NO2-)과 암모니아성 질소이온의 함유량에 따라 계면활성제를 선택적으로 첨가함으로써 반응속도를 향상시킴으로써, 수질오염에 의해 어류의 집단 폐사되는 것을 미연에 방지할 수 있는 효과가 있다.In addition, by appropriately neutralizing in accordance with the pH of the water to administer a water quality improver, by selectively adding a surfactant in accordance with the content of nitrite ions (NO 2- ) and ammonia nitrogen ions contained in the water quality to improve the reaction rate, There is an effect that can prevent the group death of fish by water pollution.
