Description

조류 억제용 조성물Composition for inhibiting algae
본 발명은 조류 억제용 조성물에 관한 것으로, 더욱 상세하게는 과산화수소 형성 물질을 포함하는 조류 억제용 조성물에 관한 것이다.TECHNICAL FIELD The present invention relates to a composition for inhibiting algae, and more particularly, to a composition for inhibiting algae containing a hydrogen peroxide forming material.
녹조현상은 부영양화된 호소나 유속이 느린 하천에서 식물성 플랑크톤인 녹조류가 크게 늘어나 물빛을 녹색으로 변화시키는 현상을 말한다. The green algae phenomenon refers to the phenomenon that the green algae, which are phytoplankton, are greatly increased in the eutrophic lake or the slow flow, and the water is changed to green.
녹조가 발생하면 물의 용존산소량이 줄어들면서 물고기와 수중생물이 죽고 악취가 나며, 해당 수역의 생태계가 파괴되어 경제적, 환경적 측면에서 많은 문제가 발생한다.When green algae occur, the amount of dissolved oxygen in the water decreases, causing fish and aquatic creatures to die, smell bad, and the ecosystem of the water area to be destroyed, resulting in many economic and environmental problems.
적조현상은 부패성 유기 오염물질, 미량금속 및 증식촉진물질이 풍부하게 용존 되어 있고, 일사량, 수온, 염분 등 환경조건이 적당하면 플랑크톤이 대량 번식하여 발생한다. 특히 생활하수가 다량 유입되고 저층에 퇴적된 영양물질이 용출되는 곳으로서 폐쇄성의 내만이나 연안에서 상습적으로 발생한다.The red tide phenomenon is abundantly soluble in perennial organic pollutants, trace metals and growth promoting substances, and if the environmental conditions such as solar radiation, water temperature and salinity are proper, a large quantity of plankton is reproduced. Especially, it is a place where large amounts of domestic wastewater are introduced and nutrients deposited in the lower layer are eluted.
적조가 일어나는 가장 큰 요인은 물의 부영양화이며, 그 외에 기온의 변화로 수온이 상승하여 미생물이 왕성하게 번식하는 경우, 바람이 적게 불어서 바닷물이 잘 섞이지 않는 경우에도 적조가 일어날 수 있다.The most important cause of red tide is eutrophication of water. In addition, when temperature changes due to temperature change, microbes grow vigorously, and red tides may occur even when the wind is not blowing so much that the sea water does not mix well.
녹조 또는 적조가 일어나면 물속에 녹아 있는 산소 농도가 낮아지기 때문에, 물속의 산소를 이용해서 호흡을 하는 어패류가 질식하여 폐사하는 일이 많이 발생한다. 또한 물고기의 아가미에 플랑크톤이 끼여 물리적으로 질식하는 경우도 있으며, 녹조 또는 적조를 일으키는 플랑크톤 중 독성을 가진 조류가 있어서 이러한 독성 때문에 폐사하기도 한다.When green tide or red tide occurs, the concentration of dissolved oxygen in the water is lowered, so that the fish and shellfish breathing using oxygen in the water suffocate and die. In addition, there is a physical suffocation of plankton in the gills of fish, and toxic algae among plankton causing red tide or red tide, and these are dead because of this toxicity.
이러한 문제점을 개선하기 위하여 황토 살포, 나노 입자 투입, 준설, 응집제 투입, 조류펜스 이용 등의 다양한 방법들이 시도되고 있다(한국등록특허 제10-1657171호, 한국등록특허 제10-0960227호, 한국등록특허 제10-0906625호). In order to solve such problems, various methods such as spraying of loess, injection of nanoparticles, dredging, introduction of coagulant, use of algae fence have been attempted (Korean Patent No. 10-1657171, Korean Patent No. 10-0960227, Patent No. 10-0906625).
그러나 황토를 투입하면 부유물질이 일시적으로 증가하여 해양생물의 호흡장애를 유발하고, 황토와 적조 또는 녹조가 결합하여 바다 밑으로 침전된 후 산성화되기 때문에 해양생물의 생리장애를 유발하여 폐사에 이르게 할 수 있다. However, when loess is added, suspended matter increases temporarily to cause respiratory disturbance of marine life, and because loess is combined with red tide or green tide, it precipitates under the sea and becomes acidified, causing a physiological disorder of marine life, .
또한 상기 방법들은 조류의 성장을 일시적으로 억제할 뿐 근본적으로 조류를 제거할 수 없으며, 침전된 물질에 의하여 이차적인 오염발생을 초래한다. In addition, the above methods temporarily inhibit the growth of algae, but can not fundamentally remove algae and cause secondary contamination by the precipitated substances.

When the content is less than 1 part by weight, the effect of addition is insignificant. When the content is more than 10 parts by weight,
상기 수소생성 촉매는 수소의 발생을 촉진하며, 생성된 수소는 과산화수소 형성 물질로부터 과산화수소의 생성을 촉진시킨다.The hydrogen generating catalyst promotes the generation of hydrogen, and the generated hydrogen accelerates the production of hydrogen peroxide from the hydrogen peroxide forming material.

The composition may further comprise an ultraviolet absorber which functions to absorb ultraviolet rays of sunlight. In the absence of an ultraviolet absorber, the composition is decomposed during use to reduce algae removal efficiency and, as a result, the composition can not be used for extended periods of time.
자외선 흡수제로는 벤조트리아졸, 하이드록시벤조페논, 하이드록시페닐트리아진 등이 제한 없이 사용될 수 있다. As ultraviolet absorber, benzotriazole, hydroxybenzophenone, hydroxyphenyltriazine and the like can be used without limitation.
자외선 흡수제의 함량은 과산화수소 형성 물질 100중량부에 대하여 1~5중량부인 것이 바람직하며, 함량이 1중량부 미만인 경우 첨가의 효과가 미미하고, 5중량부를 초과하는 경우 과산화수소의 형성이 저하되어 조류의 제거 효율이 오히려 저하된다.The content of the ultraviolet absorber is preferably 1 to 5 parts by weight based on 100 parts by weight of the hydrogen peroxide forming material.

이하 실시예 및 비교예를 통해 본 발명을 상세히 설명한다. 하기 실시예는 본 발명의 실시를 위하여 예시된 것일 뿐, 본 발명의 내용이 하기 실시예에 의하여 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to Examples and Comparative Examples. The following examples are intended to illustrate the practice of the present invention and are not intended to limit the scope of the present invention.
(실시예 1) (Example 1)
과산화수소 형성 물질로 나트륨 휴메이트를 사용하였다. Sodium humate was used as the hydrogen peroxide forming material.
물 2L가 담긴 수조에 녹조를 넣은 후, 나트륨 휴메이트를 투입하였다. A green alga was placed in a water tank containing 2 L of water, and then sodium hypochlorite was added thereto.
나트륨 휴메이트로 녹조를 처리한 후의 클로로필 a 의 농도 변화를 관찰하였다(도 1 및 2). Changes in the concentration of chlorophyll-a after treating the green tide with sodium humate were observed (FIGS. 1 and 2).
수온은 30℃이고, 상기 나트륨 휴메이트의 농도는 0.001, 0.003, 0.005, 0.007g/100㎖로 조절되었다. The water temperature was 30 占 폚, and the concentration of the sodium humate was adjusted to 0.001, 0.003, 0.005, and 0.007 g / 100 ml.
녹조를 처리한 2일 후에 있어서, 나트륨 휴메이트의 농도가 증가함에 따라 클로로필 a 의 농도가 감소하며, 이로부터 녹조가 효율적으로 제거됨을 알 수 있다(도 1a). After 2 days of treatment of the green algae, the concentration of chlorophyll-a decreases as the concentration of sodium fumate increases, indicating that the green algae are efficiently removed (Fig. 1a).
녹조를 처리한 4일 후에 있어서, 나트륨 휴메이트의 농도가 증가함에 따라 클로로필 a 의 농도가 2일 후의 경우보다 더 많이 감소하며, 이로부터 녹조가 효율적으로 제거됨을 알 수 있다(도 1b). After 4 days from the treatment of green algae, the concentration of chlorophyll-a decreases more than that after 2 days as the concentration of sodium fumate increases, which shows that green algae are efficiently removed (Fig. 1B).
녹조를 처리한 6일 후에 있어서도, 4일 후의 경우와 유사한 경향을 나타냄을 알 수 있다(도 2a). Even after 6 days after the treatment of the green algae, the same tendency as in the case after 4 days is shown (FIG. 2A).
수온을 25℃로 유지하고, 나트륨 휴메이트의 농도를 0.005g/100㎖로 조절한 경우, 시간의 경과에 따라 녹조의 제거 효율이 증가함을 알 수 있다(도 2b).When the water temperature was maintained at 25 ° C and the sodium hypochlorite concentration was adjusted to 0.005 g / 100 ml, the removal efficiency of green algae was increased with time (FIG. 2b).
도 3은 수온을 30℃로 유지한 경우, 나트륨 휴메이트의 농도 및 처리시간에 따른 녹조의 제거 효율을 나타내고 있다. Fig. 3 shows the removal efficiency of the green algae according to the concentration of the sodium humate and the treatment time when the water temperature is maintained at 30 캜.
나트륨 휴메이트의 농도 및 처리시간이 증가함에 따라 녹조의 제거 효율이 향상됨을 알 수 있다.As the concentration of sodium humate and the treatment time are increased, the removal efficiency of the green algae is improved.
(실시예 2)(Example 2)
나트륨 휴메이트 100중량부, 적철석 5중량부 및 산화철 3중량부를 혼합하여 조류 억제용 조성물을 제조하였다. 100 parts by weight of sodium humate, 5 parts by weight of hematite and 3 parts by weight of iron oxide were mixed to prepare a composition for inhibiting algae.
물 2L가 담긴 수조에 녹조를 넣은 후, 상기 조성물을 투입하였다. After the green tea tank was put in a water tank containing 2 L of water, the above composition was added.
도 4는 수온을 25℃로 유지하고, 조성물의 농도를 0.005g/100㎖로 조절한 경우, 과산화수소 형성 물질의 종류 및 처리시간에 따른 녹조의 제거 효율을 나타내고 있다. FIG. 4 shows the removal efficiency of the green algae depending on the kind of the hydrogen peroxide forming material and the treatment time when the water temperature was maintained at 25 ° C. and the concentration of the composition was adjusted to 0.005 g / 100 ml.
과산화수소 형성 물질로 휴믹산 또는 리그닌을 사용한 경우, 녹조의 제거 효율이 높지 않는데, 이는 물에 대한 낮은 용해도로 효율적인 녹조 제거 특성을 발현하지 못하기 때문이다. When humic acid or lignin is used as the hydrogen peroxide forming material, the removal efficiency of the green algae is not high because the low solubility in water does not exhibit effective algal removal characteristics.
과산화수소 형성 물질로 리그노술포네이트 또는 나트륨 휴메이트를 사용한 경우, 녹조의 제거 효율이 크게 향상됨을 알 수 있다.It can be seen that the use of lignosulfonate or sodium humate as the hydrogen peroxide forming material greatly improves the removal efficiency of the green algae.
도 5는 수온을 25℃로 유지하고, 조성물의 농도를 0.005g/100㎖로 조절한 경우, 과산화수소 형성 물질의 종류에 따른 녹조의 제거 효율을 나타내고 있다. FIG. 5 shows the removal efficiency of the green algae according to the kind of the hydrogen peroxide forming material when the water temperature is maintained at 25 ° C. and the concentration of the composition is adjusted to 0.005 g / 100 ml.
녹조를 처리한 10일 후(도 5a) 및 15일 후(도 5b)에 있어서, 리그노술포네이트 또는 나트륨 휴메이트를 사용한 경우, 녹조가 거의 제거됨을 알 수 있다. It can be seen that when lignosulfonate or sodium humate was used 10 days after the green tide treatment (Fig. 5A) and 15 days later (Fig. 5B), the green tide was almost removed.
