Description

적조방제용 약품의 조성물{COMPOSITE OF CHEMICALS FOR REMOVAL OF RED TIDE}COMPOSITE OF CHEMICALS FOR REMOVAL OF RED TIDE

본 발명은 바다의 적조현상을 방제할 수 있는 적조방제용 약품의 조성물에 관한 것으로, 더욱 상세하게는 황토분말과 황산구리, 과탄산소다, 카제인석회, 중조로 조성된 발포성 과립형태의 적조방제용 약품의 조성물에 관한 것이다.The present invention relates to a composition of a red tide control agent that can control the red tide phenomenon of the sea, and more particularly, to the red tide control agent in the form of effervescent granules, copper sulfate, sodium percarbonate, casein lime, foamed granules The composition relates to.

일반적으로, 바다가 오염되면서 적조생물의 증식이 이루어지면 바닷물을 붉게 변색시키는 적조현상이 발생되고, 이 적조현상은 바다에 서식하고 있는 어패류의 생식을 불가능하게 만들어 양식 어패류의 패사 등을 유발시키는 등 대표적인 해양오염이다.In general, when the sea is polluted and the red tide grows, red tide occurs, which causes the sea water to turn red.This red tide makes it impossible to reproduce the fish and shellfish inhabiting the sea, causing loss of cultured fish and shellfish. It is a representative marine pollution.

이러한 바다의 적조현상을 방제하기 위하여 종래에는 황토분말과 석회석을 물에 용해시켜 만든 적조방제용 약품을 사용하였는데, 이 적조방제용 약품은 자연상태의 황토를 그대로 사용하여 오히려 해저퇴적층에 의한 해저생태계의 파괴를 초래할 뿐만 아니라 적조방제의 효율이 낮고 방제시간이 과다하게 소요되는 등의 문제가 있다.In order to control the red tide phenomenon of the sea, the red tide control agent made by dissolving ocher powder and limestone in water has been used. The red tide control agent uses natural yellow soil as it is, but rather the seabed ecosystem by the seabed sedimentation layer. Not only does it cause the destruction of, but the efficiency of the red tide control is low, and there is a problem such that excessive control time is required.

또한, 황토에 활성탄, 게르마늄, 쑥, 맥반석 등을 혼합하여 만든 적조방제용 약품의 경우 적조생물과의 응집반응이 낮아 적조방제 효율이 떨어지고, 해저퇴적층을 만들어 2차해저오염을 유발시키는 등의 문제가 있다.In addition, red tide control drugs made by mixing activated carbon, germanium, wormwood, and elvan in ocher have low coagulation reactions with red tide organisms, resulting in low red tide control efficiency, and causing sedimentary sedimentation, causing secondary subsea pollution. There is.

본 발명은 이러한 종래의 문제를 개선하기 위하여 안출된 것으로, 황토분말과 황산구리, 과탄산소다, 카제인석회, 중조로 조성된 발포성 과립형태로서 침강하는 과정에서 적조생물들을 충분히 흡착 및 응집할 수 있어 적조방제의 효율이 뛰어날 뿐만 아니라 해저퇴적층을 형성하지 않아 2차해저오염을 유발하지 않는 환경친화적인 적조방제용 약품의 조성물을 제공함에 그 목적이 있다.The present invention has been made in order to improve such a conventional problem, red clay powder and copper sulfate, sodium percarbonate, casein lime, foamed granules composed of sodium bicarbonate in the process of settling the red tide organisms can be sufficiently adsorbed and aggregated red tide The purpose of the present invention is to provide an environment-friendly composition for red tide control chemicals that is not only excellent in the efficiency of control but also does not form a seabed sedimentation layer so as not to cause secondary pollution.

상기한 목적을 달성하기 위하여 본 발명은 황토분말 82~89중량%, 황산구리 3~5중량%, 과탄산소다 2~3중량%, 카제인석회 3~5중량%, 중조 3~5중량%로 조성되는 것을 특징으로 하는 적조방제용 약품의 조성물을 제공하게 된다.In order to achieve the above object, the present invention comprises 82 to 89% by weight of ocher powder, 3 to 5% by weight of copper sulfate, 2 to 3% by weight of sodium percarbonate, 3 to 5% by weight of casein lime, and 3 to 5% by weight of sodium bicarbonate. It is to provide a composition of red medicine for the control.

이하, 본 발명의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail.

본 발명의 일 실시예에 따르면, 본 발명에 따른 적조방제용 약품의 조성물은 황토분말 82~89중량%, 황산구리 3~5중량%, 과탄산소다 2~3중량%, 카제인석회 3~5중량%, 중조 3~5중량%로 조성된다.According to one embodiment of the invention, the composition of the red tide control agent according to the present invention is 82 to 89% by weight of ocher powder, 3 to 5% by weight of copper sulfate, 2 to 3% by weight of sodium percarbonate, 3 to 5 weight of casein lime %, 3 to 5% by weight of sodium bicarbonate.

먼저, 황토는 생물에 대해 무해하고 자연생태계의 물질순환이나 자연 정화의 역활이 크며, 콜로이드입자의 경우 해수중의 현탁물질을 흡착, 응집하는 성질이 있어 적조방제용 약품의 조성물로 널리 사용되고 있다.First, ocher is harmless to living organisms, and plays a large role in the material circulation and natural purification of natural ecosystems. In the case of colloidal particles, it is widely used as a composition of chemicals for red tide control because it has the property of adsorbing and flocculating suspended substances in seawater.

그러나, 황토가 정제 가공되지 않고 그대로 해수에 살포될 경우 불순물들이 그대로 해저로 침강하여 해저퇴적층이라는 2차환경오염을 유발시키게 된다.However, if the loess is applied to the seawater without being refined, the impurities settle to the seabed as it is, causing secondary environmental pollution called the seabed deposition.

따라서, 본 발명에서는 채취된 자연황토를 정제한 후, 1~1000㎛의 입자크기로 분쇄하고, 약 1000℃에서 고온건조하여 황토의 입자내에 기공을 확보함으로써 적조생물을 흡착 및 응집할 수 있는 비표면적을 극대화하게 된다.Therefore, in the present invention, after the purified natural loess is purified, it is pulverized to a particle size of 1 ~ 1000㎛, and dried at a high temperature at about 1000 ℃ to secure the pores in the particles of ocher by the ratio that can adsorb and aggregate the red algae. Maximize the surface area.

이때, 본 발명의 황토분말은 82~89중량%로 혼합하는 것이 바람직하나, 82중량%미만으로 혼합할 경우 적조생물의 흡착 및 응집효율이 떨어지고, 89중량%를 초과하여 혼합할 경우 상대적으로 황산구리나 과탄산소다, 카제인석회, 또는 중조의 혼합량이 감소되어 적조생물의 방제효율이 떨어지는 문제가 있다.At this time, the loess powder of the present invention is preferably mixed at 82 to 89% by weight, but when mixed at less than 82% by weight, the adsorption and flocculation efficiency of red tide organisms decreases, and when it is mixed in excess of 89% by weight, copper sulfate is relatively high. B. There is a problem that the control efficiency of red tide organisms decreases due to a decrease in the mixing amount of sodium percarbonate, casein lime, or heavy water.

또한, 황산구리(CuSO4)는 청색의 투명한 결정으로 비중이 2.286이며, 건조한 공기중에서 서서히 풍해(風解)되고, 가열하면 45℃에서 2분자의 물, 110℃에서 4분자의 물, 다시 250℃에서 모든 물분자를 잃고 무색의 무수물이 된다.In addition, copper sulfate (CuSO 4 ) is a blue transparent crystal with a specific gravity of 2.286. It gradually winds in dry air, and when heated, two molecules of water at 45 ° C., four molecules of water at 110 ° C., and another 250 ° C. Loses all water molecules and becomes colorless anhydride.

이때, 황산구리는 곰팡이 및 단세포식물의 생장을 억제하는 항곰팡이제로 널리 사용되는 화합물로서, 황산구리 3~5중량%로 혼합하는 것이 바람직하다.At this time, copper sulfate is a compound widely used as an antifungal agent for inhibiting the growth of mold and single cell plants, it is preferable to mix copper sulfate 3 to 5% by weight.

그러나, 본 발명에 있어서 황산구리는 3중량미만 또는 5중량%를 초과하여 혼합할 경우 항균 및 항곰팡이 작용이 저하되면서 적조생물의 생장을 적절히 억제하지 못하는 문제가 있다.However, in the present invention, when the copper sulfate is mixed less than 3% or more than 5% by weight, there is a problem in that the growth of red tide organisms is not properly suppressed while the antibacterial and antifungal action is reduced.

그리고, 과탄산소다(Na2CO3˙3H2O2)는 H2O2 를 유리시키고, 발생기산소를 발생시키어 표백살균작용을 하게 되고, 이로써 적조생물의 호흡에 필요한 CO2의 공급을 억제하는 작용을 하게 된다. And, with sodium carbonate (Na 2 CO 3˙ 3H 2 O 2) is glass and the H 2 O 2, and that the bleaching sterilization sikieo generate an oxygen generator, and thereby inhibit the supply of CO 2 necessary for the respiration of the red tide organisms Will act.

그러나, 본 발명에 있어서 과산화소다는 2중량미만 또는 3중량%를 초과하여 혼합할 경우 H2O2를 충분히 유리시키지 못하게 되어 적조생물의 호흡에 필요한 CO 2의 공급을 억제하지 못하는 문제가 있다.However, in the present invention, when mixed with less than 2% by weight or more than 3% by weight soda peroxide does not sufficiently release the H 2 O 2 there is a problem that does not inhibit the supply of CO 2 required for the breath of the red tide.

한편, 카제인석회는 단백질인 카제인과 소석회를 혼합시킨 것으로, 본 발명의 조성물에 대한 콜로이드성 전착제로서 각 조성물의 약효를 지속시키어 침강과정에서 뿐만 아니라 퇴적 후에도 퇴적물에 대한 분해활동을 지속시키게 된다.On the other hand, casein lime is a mixture of protein casein and hydrated lime, as a colloidal electrodeposition agent for the composition of the present invention to maintain the efficacy of each composition to maintain the degradation activity for the sediment not only during sedimentation but also after deposition.

그러나, 본 발명에 있어서 카제인석회는 3중량미만 또는 5중량%를 초과하여 혼합할 경우 각 조성물에 대한 전착제로서의 작용이 떨어져 침강중 또는 퇴적 후에 각 조성물의 약효가 지속되지 못하는 문제가 있다.However, casein lime in the present invention has a problem that the effect of each composition is not sustained during sedimentation or after deposition because the action as an electrodeposition agent for each composition when mixed less than 3% or more than 5% by weight.

그리고, 중조(NaHCO3)는 발포제로서 사용되어 조성물의 전체비중을 줄이게 되고, 이로써 본 발명의 살포시 해수의 수면위에 체류시간을 연장시키게 되어 적조생물의 흡착 및 응집을 돕게 된다.In addition, sodium bicarbonate (NaHCO 3 ) is used as a blowing agent to reduce the overall specific gravity of the composition, thereby extending the residence time on the surface of the sea water during the spraying of the present invention to help adsorption and aggregation of red tide organisms.

이때, 본 발명에 있어 중조는 3~5중량%로 혼합되는 것이 바람직하나, 3중량%미만으로 혼합될 경우 발포제로서의 작용이 미미하여 본 발명의 침강속도를 빠르게 하고, 5중량%를 초과하여 혼합할 경우 침강속도를 지나치게 더디게 하여 퇴적물의 분해효과를 반감시키는 문제가 있다.At this time, in the present invention, the heavy bath is preferably mixed at 3 to 5% by weight, but when mixed at less than 3% by weight, the action as a blowing agent is insignificant to speed up the sedimentation rate of the present invention, and to be mixed in excess of 5% by weight. If the sedimentation rate is too slow, there is a problem of reducing the decomposition effect of the sediment.

이와 같이 혼합된 조성물을 약간의 물을 스프레이하는 상태에서 0.1mm정도의 메시를 갖는 여과망으로 체질하게 되면 중조에서 CO2가스가 유리되면서 발포체를 형성하게 되고, 이를 다시 열풍으로 건조시켜 발포성과립상태인 분말로 제조하게 된 다.When the mixed composition is sieved with a filter net having a mesh of about 0.1 mm in the state of spraying a little water, CO 2 gas is liberated in a medium tank to form a foam, which is dried by hot air again to form a foamed granule. It is made into a powder.

그리고, 본 발명에 따른 적조방제용 약품의 분말을 해수에 살포할 경우 발포제인 중조의 작용에 의해 침강이 더디게 진행되면서 황토분말에서 적조생물에 대한 흡착 및 응집이 진행되고, 전착제인 카제인석회에 의해 황산구리와 과산화탄소의 약효가 지속되면서 적조생물의 생장을 억제하는 동시에 발생기산소를 이용하여 적조생물의 CO2호흡을 억제함으로써 적조의 번식보다 빠른 속도로 적조의 생장억제를 진행하여 적조방제의 효율성을 극대화하게 된다.When the powder of the red tide control agent according to the present invention is sprayed on the seawater, the sedimentation proceeds slowly by the action of sodium bicarbonate as a blowing agent, and the adsorption and aggregation of red tide organisms in the ocher powder proceeds, and the casein lime is an electrodeposition agent. Copper sulphate and carbon peroxide continue to inhibit the growth of red tide organisms, while suppressing the CO 2 respiration of red tide organisms by using oxygen oxygen, thereby inhibiting the growth of red tide and increasing the efficiency of red tide control. To maximize.

이와 같이, 본 발명의 상세한 설명에서는 구체적인 실시예에 관하여 설명하였으나, 이는 본 발명의 범주에서 벗어나지 않는 한도내에서 여러가지 변형이 가능함은 물론이다.As described above, in the detailed description of the present invention, specific embodiments have been described, but it is understood that various modifications can be made without departing from the scope of the present invention.

그러므로, 본 발명의 실질적인 범위는 상술된 실시예에 의해 한정되어져서는 안되며, 후술하는 청구범위 뿐만 아니라 청구범위와 균등한 구성에 의해 정해져야 함은 당연하다.Therefore, the substantial scope of the present invention should not be limited by the above-described embodiment, but should be defined by the same structure as the claims as well as the claims described below.

이상과 같이 조성되는 본 발명은 적조생물의 흡착 및 응집효율이 뛰어나고, 적조생물을 번식보다 빠른속도로 생장억제하여 적조방제효능을 극대화하며, 퇴적 후에도 퇴적물을 분해함으로써 퇴적에 의한 2차해양오염을 발생시키지 않는 등의 효과를 제공하게 된다.The present invention as described above is excellent in the adsorption and flocculation efficiency of the red tide organisms, maximizing the red tide control effect by inhibiting the growth of red tide organisms faster than the breeding, and by decomposing the sediment even after deposition, secondary marine pollution by sedimentation It does not produce such effects.
