Description

적조방제방법{The Methods of Preventive Red Tide}The Methods of Preventive Red Tide

본 발명은 적조방제에 관한 것으로, 해양생태계의 교란을 최소화하고 쉽고 간편하게 적조미생물을 사멸시키거나 생육을 저지할 수 있는 적조방제방법에 관한 것이다.The present invention relates to red tide control, to minimize the disturbance of the marine ecosystem and to a red tide control method that can easily and easily kill the red tide microorganisms or prevent growth.

영양염류 농도가 높은 해양에서 하절기에 수온이 상승하면 적조미생물이 과다하게 증식되어 가두리양식장과 어장의 경제적 피해는 물론 해양생태계의 교란을 초래하게 된다.When the water temperature rises in the summer when the nutrient concentration is high, the red tide microorganisms multiply excessively, causing economic damage to cages and fish farms, as well as disturbing marine ecosystems.

이와 같은 적조를 방제하기 위하여 종래에는 적조미생물이 밀집 증식하는 수역에 황토를 살포하는 방법을 사용하였다. 황토살포에 의한 적조의 방제는 황토의 콜로이드입자가 해수중의 영양물질, 미소플랑크톤등과 같은 현탁물질을 응집, 흡착하는 특성을 이용하여 적조미생물을 황토에 응집, 침전시키는 것이다. 황토살포에 의한 유독성 적조생물의 제거효과는 종에 따라 차이가 있으나Cocholdinium적조생물의 제거효과는 실내실험과 현장조사결과 70∼80%로 나타났다. 일본에서 실시된 산성백토의 적조미생물방제에서도Cocholdinium외 14종의 적조원인 생물을 대상으로 실험을 수행한 결과 흡착, 침강, 세포 파괴등의 효과를 확인하였다.In order to control such red tide, conventionally, a method of spraying ocher in the water where red tide microorganisms are densely multiplied has been used. The control of red tide by ocher spray is to agglomerate and settle the red tide microorganisms in the loess by using the property that the colloid particles of ocher flocculate and adsorb suspended substances such as nutrients and microplankton in seawater. The removal effect of toxic red algae by ocher spray was different according to species, but the removal effect of cocholdinium red algae was 70 ~ 80% by laboratory and field survey. In red algae microorganism control of acidic clay in Japan, experiments with 14 red tide sources including Cocholdinium confirmed the effects of adsorption, sedimentation and cell destruction.

그러나, 황토살포에 의한 적조방제방법에 의하면 적조 수역에 황토를 살포하기 위하여 육지에서 황토를 채취하여야 되므로 육지의 토양이 유실되고, 중량물인 황토를 다량 채집, 보관 및 운반하여야 되므로 적조 수역으로 신속한 수송이 어려운 문제가 있으며, 보관과 저장이 어려운 황토를 살포함에 따라 취급상의 어려움이 있었다.However, according to the red tide control method by ocher spray, it is necessary to collect the loess from the land in order to spread the loess to the red tide, so that the soil of the land is lost, and the heavy loess, which is heavy, must be collected, stored, and transported quickly to the red tide. This is a difficult problem, and there is a difficulty in handling the soil that is difficult to store and store.

황토를 살포하게 되면 일시적인 부유물 증가에 따른 부작용이 발생되고 어류의 아가미를 막히게 하여 폐사시키는 문제가 발생된다. 황토를 해양에 살포할 경우 적조미생물과 함께 황토가 해저에 침전되어 저서 생태계에 영향을 주는데, 5g/ℓ의 황토 살포시에도 10시간 경과후에는 전복의 활동력이 약화되고 24시간 경과후에는 30% 정도가 폐사되는 것으로 보고되고 있다.When the soil is sprayed, side effects are caused by the temporary increase of suspended solids, and the gills of the fish are blocked, causing a problem of death. When the loess is sprayed to the ocean, the loess is deposited on the seabed along with the red tidal microorganisms, which affects the benthic ecosystem. Even when spraying 5 g / ℓ of loess, the activity of abalone is weakened after 10 hours and about 30% after 24 hours. Is reported to be dead.

또한,Mesodinium rubrum, Alexandrium catenella, Prorocentrum micans등 대부분의 적조 미생물은 황토 살포농도가 7,500mg/ℓ 이상에서 유영정지등의 방제효과가 발휘된다(일본수산청 '82). 따라서 폭 30m, 길이 1,000m, 깊이 3m의 적조띠에 유실율 50%를 감안하여 황토 살포량을 산정해 보면 1,012ton으로 많은 량의 황토가 소요된다.In addition, most of the red tide microorganisms such as Mesodinium rubrum, Alexandrium catenella, and Prorocentrum micans have a control effect such as stopping swimming at the loess concentration of more than 7,500mg / l (Japan Fisheries Agency '82). Therefore, the amount of loess spread is estimated to be 1,012 tons, considering the reddish strip of 30m in width, 1,000m in length and 3m in depth and 50% loss rate.

최근에는 적조방제대책으로 적조수역에 오존(O3)을 주입하는 방법이 연구되고 있다. 오존은 분해되면 무독성의 산소로 전환되므로(2O3→3O2) 2차 오염을 유발하지 않고 해양생태계의 교란이 최소화되는 장점이 있다. 그러나 전력소요량이 크고 장치의 규모가 큰 오존발생기와 함께 별도로 발전기를 선박에 탐재하여야 되므로 전용 선박의 건조가 요구되는 반면에 적조발생은 일년중에 주로 하절기에 편중되므로 유휴시설이 과다하게 발생되거나, 적조시기에 맞추어 중량물인 오존발생장치와 발전기를 선박에 탑재 또는 해체하여야 되는 매우 큰 어려움이 있다.Recently, a method of injecting ozone (O 3 ) into the red tide water as a countermeasure against red tide has been studied. Ozone is converted to non-toxic oxygen when decomposed (2O 3 → 3O 2 ), which has the advantage of minimizing the disturbance of marine ecosystems without causing secondary pollution. However, since the generator needs to be inspected separately on the vessel together with the ozone generator, which has a large power requirement and a large scale of equipment, the construction of a dedicated vessel is required, while the red tide occurs mainly during the summer, resulting in excessive idle facilities or red tide. There is a great difficulty in loading or dismantling the heavy ozone generator and generator in time.

특히, 오존은 저장이 불가능하므로 적조가 과다하게 발생하여 오존량이 일시적으로 크게 소요될 경우에도 오존발생기의 생산능력을 초과하여 오존을 주입할 수 없는 문제점이 있다.In particular, since ozone is impossible to store, there is a problem in that red tide is excessively generated and ozone cannot be injected in excess of the production capacity of the ozone generator even when a large amount of ozone is temporarily required.

상술한 바와 같이 지금까지 적조방제에 대한 실효성 있는 구체적인 대책이 없음에도 불구하고 해마다 적조피해는 증가되고 있으며 효과적인 적조방제방법이 시급히 요구되는 실정이다.As described above, despite the fact that there are no effective concrete measures against red tide control, red tide damage is increasing year by year, and an effective red tide control method is urgently required.

이에 본 발명은 해양생태계의 교란과 저서생태계에 대한 2차 오염이 없고, 적조방제과정에서 소요되는 물동량이 적어 신속하고 효과적으로 적조를 방제할 수 있는 적조방제방법을 제공하는 데 그 목적이 있다.Accordingly, an object of the present invention is to provide a red tide control method capable of controlling red tide quickly and effectively because there is no disturbance of marine ecosystem and secondary pollution to benthic ecosystem, and there is little amount of trade required in the red tide control process.

본 발명에서는 해양에서 적조미생물이 밀집하여 증식된 수역 및 적조띠에 산화제인 과산화수소수(H2O2)를 살포하여 적조미생물을 사멸시키거나 생육을 저지하는 적조방제방법을 적용하였다. 과산화수소수는 발생기 산소의 높은 산화력에 의하여(H2O2→ H2O + O) 주로 규조류와 편모조류인 적조미생물을 효과적으로 사멸시킬 수 있으며 분해되어 무독한 물과 산소로 전환되므로(2H2O2→2H2O+02) 2차 오염을 초래하거나 해양생태계를 교란시키지 않는 장점이 있다.In the present invention, a red tide control method is applied to kill red tide microorganisms or prevent growth by spraying hydrogen peroxide water (H 2 O 2 ) as an oxidizing agent on the water and red tide bands that have grown by growing red tide microorganisms in the ocean. Hydrogen peroxide can effectively kill red algae, mainly diatoms and flagella algae, due to the high oxidizing power of generator oxygen (H 2 O 2 → H 2 O + O), and decomposes and converts into poisonous water and oxygen (2H 2 O 2 → 2H 2 O + 0 2 ) It has the advantage of not causing secondary pollution or disturbing the marine ecosystem.

적조에 작용되는 산화력(ORP : Oxidation Reduction Potential)을 증대시키기 위하여 상기 과산화수소수를 촉매제인 2가철염(Fe++)과 함께 살포하거나 이들의 혼합액을 살포하는 적조방제방법을 적용할 수 있는데, 이는 페놀과 같은 난분해성 유기물을 산화시키며 주로 폐수처리에 응용되었던 종래의 Fenton 산화방법과 같은 원리이다.In order to increase Oxidation Reduction Potential (ORP) applied to the red tide, the red tide control method may be applied by spraying the hydrogen peroxide with ferric salt (Fe ++ ) as a catalyst or by spraying a mixture thereof. It oxidizes hardly degradable organic substances such as phenol and is the same principle as the conventional Fenton oxidation method which was mainly applied to wastewater treatment.

과산화수소수에 의한 적조미생물의 사멸효과를 확인하기 위하여 적조미생물이 포함된 100㎖의 해수시료들에 과산화수소수를 주입하고 Magnetic Stirer를 이용하여 30분 동안 교반시킨후에 현미경으로 적조미생물의 거동을 관찰하는 실험실 규모의 실험을 수행하였다.In order to confirm the killing effect of red algae microorganisms by hydrogen peroxide, hydrogen peroxide was injected into 100 ml of seawater samples containing red algae microorganisms and stirred for 30 minutes using a magnetic stirrer. Laboratory scale experiments were performed.

실험결과는 다음 표에서와 같이 과산화수소수 주입농도 1.5㎎H2O2/ℓ에서 30분 경과후에 적조미생물의 약 12%가 유영을 중지하였고, 3㎎H2O2/ℓ 농도에서는 약 93%정도가 유영을 중지하였으며, 6㎎/ℓ이상에서는 100%가 유영을 중지함을 확인하였다. 30분을 초과하여 시간이 경과됨에 따라 유영이 중지된 미생물의 수는 증가되었으며 유영이 중지된 적조미생물들은 주로 폐사된 것으로 추정된다.As shown in the following table, about 12% of red tide microorganisms stopped swimming after 30 minutes at 1.5mgH 2 O 2 / l in hydrogen peroxide injection, and about 93% at 3mgH 2 O 2 / l. Was stopped swimming, and at 6 mg / l or more, 100% stopped swimming. As time passed over 30 minutes, the number of microorganisms that stopped swimming increased, and the red tide microorganisms that stopped swimming were presumed dead.

상기 과산화수소수의 주입시에 촉매제인 2가철염(Fe+2)을 주입하되 FeSO4·7H2O 기준 H2O2와 중량대비 1:1의 농도로 주입한 결과, 1.5㎎H2O2/ℓ(+1.5㎎ FeSO4·7H2O㎎/ℓ)에서 약 50%의 적조미생물이 유영을 중지하였으며, 3㎎H2O2/ℓ (+3㎎ FeSO4·7H2O㎎/ℓ)이상의 농도에서는 FeSO4·7H2O의 주입에 따른 큰 영향은 관찰되지 않았으며 진하게 착색되거나 침전물은 발생되지 않았다.Injecting ferric salt (Fe + 2 ) as a catalyst when the hydrogen peroxide solution was injected, but the concentration of FeSO 4 · 7H 2 O based on H 2 O 2 and 1: 1 by weight, 1.5mgH 2 O 2 FeSO 4 · 7H 2 was the /ℓ(+1.5㎎ red tide microorganism of about 50% at O㎎ / ℓ) stop swim, 3㎎H 2 O 2 / ℓ ( + 3㎎ FeSO 4 · 7H 2 O㎎ / ℓ) At the above concentration, no significant effect of FeSO 4 · 7H 2 O injection was observed and darkly colored or precipitate was not generated.

이상의 실험결과에 의하면 30분 경과시에 90%이상의 적조미생물이 유영을 중지하는 3㎎H2O2/ℓ 주입농도에서 적조를 방제하는 것이 바람직하며, 100% 사멸을 목적으로 할 경우 3∼6㎎H2O2/ℓ범위내에서 경제적인 주입농도를 확인하는 추가 실험이 바람직하고 6㎎H2O2/ℓ이상 주입은 불필요함을 확인할 수 있었다.According to the above test results, it is preferable to control red tide at 3mgH 2 O 2 / ℓ injection concentration where 90% or more of red tide microorganisms stop swimming after 30 minutes, and 3 to 6 mg for the purpose of 100% killing. Further experiments confirming the economic injection concentration within the range of H 2 O 2 / ℓ is preferable, and more than 6 mgH 2 O 2 / ℓ injection was not necessary.

과산화수소수 주입농도가 3.0㎎H2O2/ℓ에서 93%의 적조미생물이 유영정지되는 등의 방제효과를 발휘하므로 폭 30m, 길이 1,000m, 깊이 3m의 적조띠에 유실율 50%를 감안하여 50% 농도의 과산화수소수를 살포하게 되면, 0.810ton의 과산화수소수가 소요된다. 따라서 과산화수소수의 소요량은 중량대비 황토살포량의 0.08%(0.81ton/1,012ton)에 불과하므로 황토투입에 비교하여 물동량이 매우 적고 취급과 관리가 용이하다. 또한 과산화수소수의 비중은 해수와 유사한 액체이므로 적조방제애 효과적으로 사용되지 못하고 유실되는 량이 황토살포의 경우 보다 적을 것으로 예상된다,The concentration of hydrogen peroxide was controlled at 3.0 mgH 2 O 2 / l and 93% of the red tide microorganisms were suspended, thus 50% of red tide bands with a width of 30m, length of 1,000m, and depth of 3m were considered 50%. Spraying a concentration of hydrogen peroxide solution requires 0.810 tons of hydrogen peroxide water. Therefore, the required amount of hydrogen peroxide water is only 0.08% (0.81ton / 1,012ton) of the yellow soil spraying to the weight, so the amount of transportation is very small and easy to handle and manage. In addition, the specific gravity of hydrogen peroxide water is similar to that of sea water, so it is expected that the amount of lost water cannot be effectively used for red tide control, and the amount lost is lower than that of ocher spray.

과산화수소수를 해양에 살포하는 수단은 다양하게 구성할 수 있으며, 본 발명에서는 과산화수소수를 적조에 살포하는 수단으로 다수개의 노즐이 설치된 관형태의 살포기를 구성하고, 상기 살포기를 선박 또는 항공기등의 수송수단에 장착하여 펌프로 과산화수소수를 살포시키는 방법을 적용하였다.Means for spraying the hydrogen peroxide water to the ocean can be configured in various ways, in the present invention comprises a pipe-type spreader installed with a plurality of nozzles as a means for spraying the hydrogen peroxide water to the red tide, transporting the spreader to ships or aircraft A method of spraying hydrogen peroxide with a pump was applied.

과산화수소수는 소량 살포시에도 강한 방제효과가 발휘되므로 살포유량이 적고 따라서 과산화수소수와 적조수역의 해수가 충분히 혼합 및 접촉될 수 없는 단점이 있다. 본 발명에서는 상기 과산화수소수를 해수와 혼합 및 희석시켜서 유량을 증대시키고, 이와 같이 해수가 혼합되어 희석된 많은 유량의 과산화수소수를 살포하므로써 살포유량이 증대되어 적조수역에서 적조미생물과 과산화수소의 혼합 및 접촉이 잘 이루어지도록 하였다.Hydrogen peroxide water has a disadvantage in that a strong control effect is exhibited even when spraying a small amount, so the spraying flow rate is small, and thus the hydrogen peroxide water and the seawater in the red tide can not be sufficiently mixed and contacted. In the present invention, the flow rate is increased by mixing and diluting the hydrogen peroxide water with the seawater, and the spraying flow rate is increased by spraying the hydrogen peroxide water with a large flow rate of the diluted seawater. Thus, the red tide microorganism and hydrogen peroxide are mixed and contacted in the red tide water. This worked well.

본 발명에서는 과산화수소수와 적조의 혼합은 선박의 추진용 프로펠러의 교반력을 이용토록 하였다. 펌프로 해수를 흡입하여 후면으로 분출시켜서 추진력을 얻는 형태의 선박을 이용할 경우에는 추진용 펌프의 흡입구에 과산화수소수를 투입하고 추진용 펌프의 분출 및 교반력을 이용하여 과산화수소수를 살포하고 적조미생물과 접촉이 이루어지도록 할 수 있다.In the present invention, the mixing of the hydrogen peroxide water and the red tide was to use the stirring force of the propeller for propulsion of the ship. When using a type of vessel in which seawater is sucked by the pump and ejected to the rear to obtain propulsion, hydrogen peroxide water is introduced into the suction port of the propulsion pump, and the hydrogen peroxide water is sprayed using the ejection and stirring power of the propulsion pump. Contact can be made.

또한 펌프를 선박에 탑재하고 해수를 양수하여 적조 수역에 분출시킬 수 있도록 구성하고 펌프의 흡입관에 과산화수소수 주입관을 연결시켜서 구성하므로써, 펌프의 교반력에 의해서 해수와 과산화수소수가 충분히 혼합되면서 펌프의 토출압력에 의해서 적조수역으로 해수가 혼합된 과산화수소수를 살포하는 적조방제방법을 적용할 수 있다.In addition, the pump is mounted on a ship, pumps seawater to be discharged into the red tide, and connects the hydrogen peroxide inlet pipe to the suction pipe of the pump. The red tide control method can be applied to spray hydrogen peroxide water mixed with seawater by the pressure.

화재진압용 소방선과 소방용 노즐을 이용하게 되면 과산화수소수를 해수에 혼합 및 희석시켜서 살포할 수 있으므로 별도의 선박이나 장치를 축조하지 않고서도 적조를 쉽게 방제할 수 있게 된다.By using fire fighting firefighters and fire nozzles, hydrogen peroxide can be sprayed by mixing and diluting the water with seawater, making it easy to control red tide without constructing a separate ship or device.

Hydrogen peroxide water in the field is an embodiment for ejecting. Various types of agitating blades (not shown) may be attached to the periphery of the nozzle to provide a buoy to the spreader so that the nozzle is located at a certain depth below the surface of the water or to increase agitation force.
