Description

콜로이드 물질의 자외선 투과율에 대한 측정 장치{Measuring device for ultraviolet transmittance of colloidal material}Measuring device for ultraviolet transmittance of colloidal material

본 발명은 용매 속에 미세한 입자를 가지고 있는 콜로이드 물질의 빛 투과성에 대한 측정 장치이다. 강이나 하천과 같은 콜로이드 물질에서 표면으로부터 특정 수심에 해당되는 자외선 투과율을 측정 및 연구하기 위한 장치로 강이나 하천 상태에 따라 수생 식물의 광합성을 위한 최소한의 깊이를 알기 위함을 연구하는 장치.The present invention is a measuring device for the light transmittance of a colloidal material having fine particles in a solvent. A device for measuring and studying the UV transmittance corresponding to a certain depth from a surface in a colloidal material such as a river or a river. A device for studying the minimum depth for photosynthesis of aquatic plants according to river or river conditions.

일정 세기의 자외선을 강이나 하천의 표면에서 수심을 향해 투과하며, 밑에서는 자외선이 감지 될 때까지 자외선 감지 bar가 상승하며 자외선 투과율을 계산할 수 있도록 한다.Ultraviolet rays of a certain intensity are transmitted from the surface of the river or river toward the depth, and the UV detection bar rises until the ultraviolet rays are detected from the bottom, and the UV transmittance can be calculated.

수중식물과 침전물에 의한 용존산소 변화량 결정에 대한 연구를 바탕으로 수질자료에 따르면 탄천은 상류의 부영양화 지역과 하류의 강부수성 지역으로 구분되며 상류는 수초의 광합성과 호흡이, 하류는 침전물 산소요구량이 수중 용존산소 농도 결정에 주 역할을 하고 있다. Based on the study on the determination of dissolved oxygen change by aquatic plants and sediments, water quality data shows that the Tancheon is divided into the upper eutrophication zone and the downstream submerged zone. It plays a major role in determining dissolved oxygen concentration in water.

부유물질량이란 수중에 부유하면서 물을 흐리게 하고 있는 직경 2mm이하의 물질의 양을 의미한다. 부유물질량은 2mm눈금의 여과기로 여과한 후 건조시켜 무게를 측정해서 시료 1L에 포함되어지는 고형물의 양을 측량한 것으로, 플랑크톤 등의 생물의 시체나 대변이나 이것들에 부착하는 미생물 등의 유기물, 점토 미립자등의 무기물들이 포함되어 있다. 부유물질량이 커지면 물의 투명도 등의 외관이 악회되는 것 외에 수중생물들의 호흡이나 수중 식물의 광합성에 영향을 주기도 하며, 무기질소와 무기인 등의 무기성 성분은 부영양화현상을 일으키는 요인이 된다.The amount of suspended solids refers to the amount of suspended solids in the water and less than 2mm in diameter. The amount of suspended solids is filtered through a 2mm scale filter, dried and weighed to measure the amount of solids contained in 1L of sample.The organic matter such as plankton and other organisms such as feces and microorganisms attached to these materials, clay Inorganic materials such as fine particles are included. Increasing the amount of suspended solids not only deteriorates the appearance of water, but also affects the breathing of aquatic organisms and photosynthesis of aquatic plants. Inorganic components such as inorganic nitrogen and inorganic phosphorus cause eutrophication.

본 발명 및 연구 과제는 강이나 하천의 조도(자외선)의 투과율에 대해 조사하여, 강물 혼탁도를 디지털 수치화로 나타내며, 이에 살기에 적합한 수생 식물에 대해 안내를 해준다.The present invention and research aims to investigate the transmittance of roughness (ultraviolet ray) in rivers or rivers, and represents the turbidity of river water by digital digitization, which guides aquatic plants suitable for living.

본 발명은 강물의 샘플을 수거하여 담을 수 있는 장치를 구비하며, 해당 장치에서 수면에서 수중으로 나아가는 자외선의 깊이를 측정하여 수거된 강물의 자외선 투과 깊이를 찾는다.The present invention includes a device capable of collecting and holding a sample of the river, and finds the UV transmission depth of the collected river by measuring the depth of ultraviolet light from the surface to the water in the device.

본 발명은 자외선의 투과 깊이를 디스플레이를 통해 나타내며, 이와 함께 데이터에 저장된 수생식물의 평균 키 및 광합성에 필요한 최소 자외선 요구량을 바탕으로 해당 강물에서 수생식물의 생육을 위한 강물의 깊이를 알아보도록 한다.The present invention shows the transmission depth of the ultraviolet through the display, and together with the average height of the aquatic plants stored in the data and the minimum UV requirements required for photosynthesis to determine the depth of the river for the growth of aquatic plants in the river.

본 발명은 강물에서 자외선이 통과 될 수 있는 깊이를 알아 볼 수 있으며, 이를 통해 강물의 종류 및 위치에 따라 어떠한 수생식물이 살 수 있는지 알아 볼 수 있으며, 이를 통해 향후 COD 및 BOD의 변화 추이를 예상할 수 있다.The present invention can find out the depth through which the ultraviolet light can pass through the river, and through this, it is possible to find out which aquatic plants can live according to the type and location of the river, and through this, it is expected to change the future COD and BOD changes. can do.

본 발명은 하천의 정비에 있어서 무조건 하천을 깊게만 하려는 공사를 진행하는데 오히려 이러한 공사는 수중식물에 햇빛이 도달하지 못하게 하여 광합성이 힘들어짐으로 죽은 하천을 만들게 됨을 증명할 수 있다. 때문에 하천 정비에 있어서도 혼탁도가 낮은 하천은 수심을 깊게 하되 혼탁도가 심한 하천은 수심이 깊으면 수중식물이 살 수 없음을 확장 연구할 수 있다.The present invention proceeds to the construction of the river only to deepen unconditionally in the maintenance of the river, but rather, such construction can prove that the photosynthesis is difficult to make a river that is difficult to reach the aquatic plants. Therefore, even in the maintenance of rivers, streams with low turbidity can deepen the depth, but rivers with severe turbidity can be extended to study that underwater plants cannot live if the depth is deep.
