Description

선박탑재형 유해 조류 예찰-방제 방법 및 시스템{Preliminary Observation and Prevention Method and System of harmful algae on board vessel}Preliminary Observation and Prevention Method and System of harmful algae on board vessel}

본 발명은 유해조류 예찰-방제 방법 및 시스템에 관한 것이다. 구체적으로는 선박에 탑재되는 구조의 유해조류 예찰-방제 방법 및 시스템에 관한 것이다.The present invention relates to a method and system for predicting and controlling harmful birds. Specifically, it relates to a method and system for predicting and controlling harmful algae in a structure mounted on a ship.

녹조현상이란 부영양화된 호수나 유속이 느린 하천에서 부유성의 조류, 즉, 식물플랑크톤이 대량 증식하여 수면에 집적함으로써 물색을 현저하게 녹색으로 변화시키는 현상을 가리키는 말이다. Green algae refers to the phenomenon of floating algae, i.e., phytoplankton, mass-proliferating and accumulating on the water surface in a eutrophicized lake or a river with a slow flow rate, which significantly changes the color of the green.

이러한 녹조현상은 일반적으로 담수에서만 발생하는데 공장폐수와 생활하수, 비료, 농약, 가축과 사람의 분뇨 등등 각종 육상 오염물질들이 강 또는 호수로 유입되고 수역의 하부에 침작되어 박테리아에 의해 분해되며 분해된 유기물들이 플랑크톤의 먹이가 되는 질소와 인을 생성시켜 해수 및 담수에서 녹조가 발생하게 된다. 이러한 녹조는 수중의 용존산소를 감소시키며, 독성녹조 및 각종 녹조플랑크톤을 생성시켜 어류 및 수생생물을 폐사시킨다.These green algae phenomena generally occur only in fresh water. Plant land and sewage, fertilizers, pesticides, livestock and human manure, etc. various land contaminants flow into rivers or lakes, are deposited in the lower part of the water and decomposed and decomposed by bacteria. Organic matter produces nitrogen and phosphorus, which are food for plankton, and green algae are generated in seawater and freshwater. These green algae reduce dissolved oxygen in water, and produce toxic green algae and various green algae plankton, thereby killing fish and aquatic organisms.

또한, 육지로부터 대량 유입된 유기물들이 침전된 수역 저부에는 침전된 중금속들이 수중으로 용출되어 담수를 오염시키고 어류를 중독시킬 수 있으며, 나아가서는 환경파괴 및 자연 미관의 손상 등 많은 문제점을 불러일으키게 된다. In addition, the precipitated heavy metals are eluted into the water at the bottom of the water body where large amounts of organic matter from the land are precipitated, which can contaminate fresh water and poison fish, and further cause many problems such as environmental destruction and damage to natural aesthetics.

한편, 녹조를 일으키는 미생물로는 녹조류, 규조류, 남조류 및 식물성 편모충류 등이 있으며, 이 중에서 남조류가 주된 원인이 된다.On the other hand, microorganisms causing green algae include green algae, diatoms, blue-green algae and vegetable flagella, among which blue-green algae are the main cause.

적조현상은 육지로부터 유기오염 물질이나 질소 인 등이 바다로 다량 유입되어 플랑크톤의 비정상적인 증식으로 인해 바다의 색깔이 적색, 적갈색, 황갈색, 녹색, 황녹색 및 황색 등으로 변하는 현상을 말한다. 이러한 적조를 일으키는 원인생물은 주로 편모조류 및 규조류이며, 이 외에도 섬모충류, 남조류 및 적색세균 등이 적조를 유발시키는 것으로 알려져 있다.Red tide refers to a phenomenon in which large amounts of organic pollutants or nitrogen phosphorus from the land flow into the sea, and the color of the sea changes to red, reddish brown, tan, green, yellow green, and yellow due to abnormal proliferation of plankton. The causative organisms causing red tide are mainly flagella and diatoms. In addition, cilia, blue-green algae, and red bacteria are known to induce red tide.

한편, 적조가 발생하게 되면 수중의 용존 산소가 결핍되어 바다는 순식간에 산소가 희박한 상태가 되어 물고기 및 어폐류가 대량 폐사하게 되고, 대량 번식된 플랑크톤은 물고기의 아가미에 붙어서 물고기를 질식시키기도 하며, 특히 편모조류인 코콜리디니움은 유해 독소를 발생시켜 물고기의 죽음을 초래하게 된다. On the other hand, when red tide occurs, the dissolved oxygen in the water is deficient, and the sea is quickly depleted of oxygen, causing a large amount of fish and fish to die, and the mass-produced plankton sticks to the gills of the fish to smother the fish. In particular, flagellum, coccolidinium, generates harmful toxins, leading to the death of fish.

또한, 현재 세계 20억 이상의 인구가 소비하는 동물성 단백질의 50％ 가량은 바다에서 공급되는데 적조현상에 따른 해양생태계의 파괴는 이러한 식량자원에도 심각한 영향을 미치게 되며, 나아가 수역 이용 가치를 저하시키고, 더 나아가 경제적인 가치를 초월하여 커다란 환경 문제를 야기하게 된다.In addition, about 50% of the animal protein currently consumed by more than 2 billion people in the world is supplied from the sea, and the destruction of the marine ecosystem due to the red tide has a serious impact on these food resources, further deteriorating the value of water use. Furthermore, it transcends economic value and causes great environmental problems.

기존의 유해조류 예찰 기술은 크게 선박이나 샘플러를 이용하여 시료를 채취 후에 실험실에서 분석하는 방법과 휴대용 측정기를 사용하여 직접 측정하시는 방법, 광 방식을 이용하여 원격으로 측정하는 방법 등이 있다.Existing harmful algae prediction techniques are largely divided into methods of analyzing in a laboratory after taking a sample using a ship or sampler, measuring directly using a portable measuring instrument, and measuring remotely using an optical method.

실험실에서 분석하는 방식은 샘플링 위치에 따라 대표성이 달라지며, 샘플 이동시 유해조류의 변화에 대한 오차가 있다.The method of analysis in the laboratory varies depending on the sampling location, and there is an error in the change of harmful algae when moving the sample.

휴대용 측정기를 사용하는 방식은 실험실에서 분석하는 방식에 비해 정확성이 떨어지는 단점이 있고, 두 방식 모두 직접 분석요원이 시료를 채취하거나 분석을 해야하는 번거로움이 있다.The method of using a handheld measuring instrument has a disadvantage in that accuracy is lower than that of a laboratory analysis method, and both methods have a problem in that an analytical agent must collect a sample or perform an analysis.

기존의 유해조류 방제 기술은 황토 및 약제를 뿌리거나, 초음파를 활용하는 방법이 활용되어지고 있으나, 이들 방식 모두 효율이 떨어지고, 이미 대량 번식 이후에 처리하기 때문에 그에 대한 투입 비용은 더 많이 소요되는 단점이 있다.Conventional methods for controlling harmful algae include spraying ocher and drugs, or using ultrasound, but these methods are less efficient, and they are already processed after mass propagation, so the input cost is higher. There is this.

이하에서는 도면을 참고하면서 선박형 녹조 조기예찰 시스템의 구조 및 광 경로 확보에 관한 기술구성을 설명하고자 한다.Hereinafter, with reference to the drawings, to describe the structure of the ship-type green algae early prediction system and the technical configuration for securing the optical path.

도 1은 본 발명에 따른 선박형 녹조 조기예찰 시스템 기본 구조를 나타낸다.1 shows a basic structure of a green algae early prediction system according to the present invention.

본 구조에 있어서, 녹조 조기예찰 시스템을 포함한 일반적인 광학방식의 수질 측정 시스템은 광원부(LED)와 수광부가 인접하여 위치할 수 있다.In this structure, a water quality measurement system of a general optical method including a green algae early prediction system may be positioned adjacent to a light source unit (LED) and a light receiving unit.

광원으로 LED를 쓰는 이유는 Laser에 비하여 상대적으로 저렴하며, 낮은 광출력에도 불구하고 근거리 측정을 위한 용도로 충분하기 때문이다.The reason why LED is used as a light source is that it is relatively cheaper than a laser and is sufficient for short-distance measurement despite low light output.

광원부와 수광부는 동일 방향에 위치하거나, 90도 만큼 배치할 수 있으나, 수광부와 광원부가 모두 인접하여 배치될 수 있다.The light source unit and the light receiving unit may be located in the same direction or may be arranged by 90 degrees, but both the light receiving unit and the light source unit may be disposed adjacent to each other.

녹조 조기예찰 시스템을 설치하기 위해서는 평평한 선박 바닥에 측정용 윈도우를 배치하고, 광원부와 수광부를 위치할 수 있다.In order to install the green algae early prediction system, a window for measurement may be arranged on the bottom of a flat ship, and a light source unit and a light receiving unit may be positioned.

도 2는 본 발명에 따른 선박형 녹조 조기예찰 시스템 보완 구조에 관한 실시예 1을 나타낸다.Figure 2 shows a first embodiment of the complementary structure of the ship-shaped green algae early prediction system according to the present invention.

녹조 조기예찰 시스템의 구조를 설치하기 위해서는 평평한 선박 바닥을 도 2와 같이 요철 형태로 구성할 수 있다.In order to install the structure of the green algae early prediction system, the flat ship bottom may be configured in an uneven shape as shown in FIG. 2.

이때 광원부는 측면에, 수광부는 상부에 위치시켜 측정하며, 광원부와 수광부가 떨어져 있기 때문에 광원으로 LED보다 Laser를 사용하는 것이 바람직하다.At this time, it is preferable to use a laser rather than an LED as a light source because the light source is positioned on the side and the light receiving unit is positioned on the upper side and is separated from the light source unit.

도 3은 본 발명에 따른 선박형 녹조 조기예찰 시스템 보완 구조 실시예 1-1을 나타낸다.Figure 3 shows a ship-shaped green algae early prediction system complementary structure Example 1-1 according to the present invention.

수광부를 상부에 배치하고, 충분한 공간을 확보하기 때문에 동일한 광원부에 반응하는 여러 개의 측정위치를 확보할 수 있다. 도 3의 실시예 1-1은 직진성이 좋은 Laser를 사용하여 하나의 광원으로 여러 개의 수광부를 배치하는 예를 보인 것에 해당된다.Since the light-receiving portion is disposed on the upper portion and sufficient space is secured, multiple measurement positions in response to the same light source portion can be secured. Example 1-1 of FIG. 3 corresponds to an example in which a plurality of light receiving units are disposed as one light source using a laser having good straightness.

수광부의 수가 늘어나면 측정 영역이 증대되어 측정신호의 세기가 커지고, 측정할 수 있는 최소 한계가 낮아지며 정밀성이 증대되는 효과를 보인다.As the number of light-receiving units increases, the measurement area increases, the intensity of the measurement signal increases, the minimum limit for measurement decreases, and the precision increases.

도 4는 본 발명에 따른 선박형 녹조 조기예찰 시스템 보완 구조 실시예 2를 나타낸다.4 shows a second embodiment of a complementary structure of a ship-shaped green algae early prediction system according to the present invention.

실시예 1과 동일한 구조에서 요철 구조의 선박 바닥의 광원부 반대쪽에 반사경을 설치하여 레이저를 반사 시켜 수광부를 통과하는 레이저 경로를 2개로 형성할 수 있다. In the same structure as in Example 1, a reflector is installed on the opposite side of the light source portion of the bottom of the vessel having an uneven structure to reflect the laser to form two laser paths through the light receiving portion.

이때 레이저 광원을 정확히 레이저 광원부로 반사 시키도록 미러를 설치하면, 광원부의 레이저가 손상될 수 있고, 동일 경로에 레이저가 반사되기 때문에 미세하게 비틀리게 반사 시켜 레이저 경로를 추가로 확보하면서 레이저 광원을 보호한다.At this time, if a mirror is installed to accurately reflect the laser light source to the laser light source part, the laser of the light source part may be damaged, and because the laser is reflected in the same path, it is slightly twisted and reflected to secure the laser light path while protecting the laser light source. do.

이때 측정부의 측정 범위 안에 레이저 반사 경로가 배치되도록 미러는 1도 이내에서 비틀리게 설치하는 것이 바람직하다.At this time, it is preferable that the mirror is twisted within 1 degree so that the laser reflection path is disposed within the measurement range of the measurement unit.

도 5는 본 발명에 따른 선박형 녹조 조기예찰 시스템 보완 구조 실시예 3을 나타낸다.5 shows a third embodiment of a complementary structure of a ship-shaped green algae early prediction system according to the present invention.

실시예 2의 반사 경로를 추가하는 아이디어를 확장하여 더욱 많은 경로를 구성하는 것이 가능하다.It is possible to construct more paths by extending the idea of adding the reflection path of Example 2.

다수 개의 경로를 다수의 미러를 양 측면에 배치하여 추가 경로를 확보할 수 있다.Additional paths can be secured by placing multiple paths on multiple sides of the mirror.

또한, 다수의 소형 미러 대신 하나의 오목 미러를 양 측면에 하나씩 배치하고, 레이저를 약간 비껴 나게 조사함으로써 다수의 경로를 확보할 수 있다.In addition, a plurality of paths can be secured by arranging one concave mirror one by one on both sides instead of a plurality of small mirrors, and irradiating the laser slightly off.
