초기 강우시 농약, 비료 등의 침출수 등의 유입으로 인하여 호수의 수중의 오염도는 증가하게 된다. During the initial rainfall, the contamination of the lake water is increased due to the inflow of leachate such as pesticides and fertilizers.

이에 본 발명은 호소의 부영양화를 억제하고 맑은 수질을 유지하기 위하여 패각을 이용하여 질소와 인을 제거하였다.Therefore, the present invention removed nitrogen and phosphorus by using a shell to suppress eutrophication of the appeal and to maintain a clear water quality.

The present invention is an appeal purifying device using the TiO 2 photocatalytic aeration device developed by the company, and developed a filter medium in which shell shell + ocher + zeolite (shell shell + ocher) were mixed to improve nitrogen and phosphorus removal efficiency. Ceramic and filter media were injected into the final outlet to maximize nitrogen and phosphorus removal efficiency.

도 1은 본 발명의 실시예에 따른 호수 정화 장치의 개략도이다.1 is a schematic diagram of a lake purification apparatus according to an embodiment of the present invention.

본 발명의 실시예에 따른 호수 정화 장치는 크게, 유입부(120), 원수이송펌프(150), 산소발생기(110), 광촉매 폭기장치(160), 산소용해기(170), 배출부(180)를 포함하여 이루어진다.Lake purification apparatus according to an embodiment of the present invention is largely, the inlet portion 120, the raw water transfer pump 150, the oxygen generator 110, the photocatalytic aerator 160, oxygen dissolver 170, discharge unit 180 )

상기 유입부(120)는 호수의 원수를 받아들이는 부분으로, 여재층(130)을 포 함하고 있다.The inlet 120 is a portion that receives the raw water of the lake, and includes a filter layer (130).

상기 여재층(130)에 내장된 여재는 제올라이트, 패각, 및 황토를 분말화하여 이를 소결하여 성형하는 것에 의해 제조된다. 이 때, 상기 여재의 크기는 일정한 입도를 가지게 하거나, 여러 종류의 입도를 가지게 할 수 있다.The media embedded in the media layer 130 is manufactured by sintering and molding zeolite, shell, and ocher. At this time, the size of the filter medium may have a certain particle size, or may have various kinds of particle sizes.

상기 여재층(130)에 의해 여과된 원수에 산소발생기(110)에 의해 발생된 산소가 혼합된다.Oxygen generated by the oxygen generator 110 is mixed with the raw water filtered by the filter layer 130.

그리고, 상기 산소가 혼합된 원수는 원수이송펌프(150)에 의해 다음단계로 이송되게 된다.Then, the raw water mixed with oxygen is transferred to the next step by the raw water transfer pump 150.

본 발명에서는 유입부(120)에 여재층(130)을 사용하기 때문에 상기 원수이송펌프(150) 전에 협잡물을 제거하기 위한 필터의 설치가 반드시 요구되지 않는다. In the present invention, since the filter layer 130 is used at the inlet 120, the filter for removing the contaminants is not necessarily required before the raw water transfer pump 150.

상기 원수이송펌프(150)의 전방 또는 후방에는 공급되는 원수량을 조절하기 위한 조절밸브(140)가 설치된다.A control valve 140 for adjusting the amount of raw water supplied is installed at the front or rear of the raw water transfer pump 150.

그리고, 산소발생기(110)는 원수에 용존산소 농도를 높이기 위한 장치이다.And, the oxygen generator 110 is a device for increasing the dissolved oxygen concentration in the raw water.

일반적으로 호소나 연못에 수중 용존산소가 부족할 시에는 호소나 연못이 혐기성화 되어 연못 바닥에서의 인의 방출이 촉진화 되어 녹조 발생을 촉진하게 되므로, 원수에의 산소의 공급은 중요하다.In general, when there is a lack of dissolved oxygen in lakes or ponds, the supply of oxygen to the raw water is important because the lakes or ponds are anaerobic and the release of phosphorus from the bottom of the pond is accelerated to promote the formation of algae.

대기에 있는 공기 중 산소를 고농도로 만들어서 일반적인 포기 장치보다 작은 면적과 시설로 더 높은 효율을 얻을 수 있다.Higher concentrations of oxygen in the atmosphere can be achieved with smaller footprints and facilities than conventional aeration systems.

상기 산소발생기(110)로는 공지의 멤브레인을 이용한 산소발생기를 이용할 수 있다.As the oxygen generator 110, an oxygen generator using a known membrane may be used.

상기 산소발생기(300)로부터 산소를 배출하는 관은 상기 유입부(120)로부터 연결된 관과 만나서 혼합되어 상기 원수이송펌프(150)로 공급된다.A pipe for discharging oxygen from the oxygen generator 300 is mixed with the pipe connected from the inlet 120 is supplied to the raw water transfer pump 150.

상기 광촉매 폭기장치(160)에는 이산화티타늄(TiO2) 촉매가 외벽에 코팅되고 그 내부에 UV램프가 설치된 투명관이 다수 설치된다.The photocatalytic aeration device 160 is provided with a plurality of transparent tubes in which a titanium dioxide (TiO 2 ) catalyst is coated on the outer wall and UV lamps are installed therein.

상기 투명관에 의한 원수 내의 오염물질의 제거과정을 상술하면 다음과 같다.The process of removing contaminants in raw water by the transparent tube is as follows.

자외선의 광에너지를 이산화티타늄에 조사하여 이산화티타늄 표면에 OH 라디컬(radical)을 생성시켜 유기물질을 제거할 수 있게 되는데, 이는 반도체인 이산화티타늄 표면에 빛에너지의 조사가 이루어지게 되면 이산화티타늄 밸런스 밴드(valance band)에는 전자가 유도 밴드(conduction band)로 전이되고, 상기 밸런스 밴드에는 전자가 비어있는 양공(positive hole)을 남기게 된다. By irradiating titanium dioxide with light energy of ultraviolet rays, OH radicals are generated on the surface of titanium dioxide to remove organic substances. When the energy is irradiated on the surface of titanium dioxide, a semiconductor, the balance of titanium dioxide In the band, the electrons are transferred to the induction band, and in the balance band, the electrons are left with a positive hole.

이때 전자가 전이되는데 필요한 광에너지는 밴드갭(band gab)에 해당하는 약 3.2eV 정도의 에너지가 필요하며, 이 에너지를 발생시키기 위하여 상기 UV램프(미도시)는 254nm 이하의 자외선을 조사할 수 있는 것을 사용한다.In this case, the light energy required for electron transfer is about 3.2 eV corresponding to a band gap, and the UV lamp (not shown) can irradiate ultraviolet rays of 254 nm or less to generate this energy. Use what you have.

이렇게 생긴 e-CB(유도 밴드에 전이된 전자), h-VB(밸런스 밴드에 남은 양공)은 이산화티타늄 표면에서 확산, 이동되게 되는데, 이렇게 확산된 h-VB는 물속의 수산화 이온과 반응해서 OH 라디칼을 생성하고 또 물분자와 반응해서 OH 라디칼과 수소이온(H+)을 생성시키기도 하며 직접 VOC물질과 반응하여 VOC물질을 산화하기도 한다. The e-CB (electrons transferred to the induction band) and h-VB (holes remaining in the balance band) are diffused and moved on the surface of the titanium dioxide. The diffused h-VB reacts with hydroxide ions in water to give OH It generates radicals and reacts with water molecules to generate OH radicals and hydrogen ions (H + ), and directly reacts with VOCs to oxidize VOCs.

e-CB은 수중 산소와 반응해서 초산화 라디칼(superoxide radical)(O·)을 만들고, 다시 초산화 라디칼은 물분자와 반응해서 두개의 OH 라디칼과 두개의 수산화이온(OH-), 그리고 산소 한 분자(O2)를 만들거나 H+와 반응하여 HO2O2를 만들고 결국은 H2O2를 생성해 이 H2O2가 몇 가지 반응경로를 거쳐 OH 라디컬이 유기물질 산화에 관계하게 된다. e-CB reacts with oxygen in water to form superoxide radicals (O ·), which in turn react with water molecules to produce two OH radicals, two hydroxide ions (OH ), and one oxygen The molecules make (O 2 ) or react with H + to form HO 2 O 2, which in turn generates H 2 O 2, which then passes through several reaction pathways, where OH radicals are involved in the oxidation of organic matter.

결국 이러한 몇 단계의 과정을 거쳐서 생성된 OH 라디컬이 유기물질과 반응해서 VOC 물질을 제거하게 된다.As a result, the OH radicals generated through these several steps react with the organic material to remove the VOC material.

따라서, 상기 광촉매 폭기장치(160)의 저부로 원수가 유입관을 통해 공급하면, 상기 투명관에서 발생하는 자외선의 광에너지 및 이산화티타늄 촉매에 의해 원수내의 오염물질이 제거된다.Therefore, when the raw water is supplied to the bottom of the photocatalytic aeration device 160 through the inlet pipe, contaminants in the raw water are removed by the light energy of the ultraviolet light and the titanium dioxide catalyst generated in the transparent pipe.

전원(100)은 상기 원수이송펌프(150), 상기 산소발생기(110), 및 상기 UV램프에 전력을 공급한다. The power supply 100 supplies power to the raw water transfer pump 150, the oxygen generator 110, and the UV lamp.

상기 산소용해기(170)는 상기 산소발생기(110)에서 발생된 고농도 산소를 원수에 용해 시키기 위한 장치로써, 상기 원수와 상기 산소의 접촉면적 및 접촉시간을 늘이면서, 그 내부에서 난류를 일으켜 용존산소량을 증대시키게 된다.The oxygen dissolver 170 is a device for dissolving the high concentration oxygen generated in the oxygen generator 110 in raw water, while increasing the contact area and the contact time of the raw water and the oxygen, causing turbulence therein dissolved This increases the amount of oxygen.

따라서, 상기 산소용해기(170)를 구현하기 위해, 플렉시블한 튜브를 원통형태로 감아서 제조할 수 있다.Therefore, in order to implement the oxygen dissolver 170, it can be manufactured by winding a flexible tube in a cylindrical shape.

또는, 상기 산소용해기(170)는 경사판을 이용한 통로를 지그재그의 형태로 길게 형성하여 산소와 원수의 접촉시간 및 접촉면적을 늘이면서, 장치 전체의 크기 는 줄일 수 있는 산소용해기를 사용하는 것도 가능하다.Alternatively, the oxygen dissolver 170 may form a passage using an inclined plate in the form of a zigzag to increase the contact time and the contact area of oxygen and raw water, and may use an oxygen dissolver that can reduce the size of the entire apparatus. Do.

상기 산소용해기를 지난 원수는 배출부(180)를 통해 다시 호수로 재유입된다.The raw water passing through the oxygen dissolver is reintroduced back into the lake through the discharge unit 180.

상기 배출부(180)는 상기 유입부(120)와 마찬가지로 패각, 황토, 제올라이트를 포함하는 여재를 내장하고 있다. 따라서, 원수 속에 포함된 인 및 질소를 제거하는 것이 가능하다.Like the inlet 120, the discharge unit 180 includes a media including shells, loess, and zeolite. Thus, it is possible to remove phosphorus and nitrogen contained in raw water.

이하, 본 발명의 작동과정을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

본 발명의 호수정화장치를 살펴보면 원수유입(산소공급)-> 광촉매장치->산소용해기->처리수의 방류의 장치로 구성되어있다.Looking at the lake purification apparatus of the present invention is composed of raw water inflow (oxygen supply)-> photocatalyst device-> oxygen dissolver-> discharge of treated water.

최초 연못으로부터 유입수가 세라믹화한 여재층을 통과하게 되는데 이때 세라믹화 된 상기 유입부(120)의 여재에 의해 1차적으로 PO4-P(인산염인)와 N(질소)의 제거가 이루어진다. SS(부유물질) 또한 상기 여재의 공극에 의하여 제거가 이루어진다.The inflow water from the first pond passes through the ceramicized filter bed, and the removal of PO4-P (phosphate) and N (nitrogen) is primarily performed by the filter medium of the ceramic inlet 120. SS (floating material) is also removed by the pores of the media.

1차적으로 불순물 등이 제거된 원수에 90%이상의 고순도의 산소를 주입한 후에 광촉매 폭기장치(160)로 우수를 유입시킨다. After injecting oxygen of high purity of 90% or more into raw water from which impurities and the like are first removed, rainwater is introduced into the photocatalyst aeration device 160.

유입된 우수는 광촉매 장치의 자외선의 광 에너지와 TiO2촉매를 이용하여 오염물질을 제거시킨 후 상기 산소용해기(170)로 유입된다.The introduced rainwater is introduced into the oxygen dissolving unit 170 after removing contaminants using the TiO 2 catalyst and the light energy of ultraviolet light of the photocatalyst device.

상기 산소용해기(170)로 유입된 우수는 호수에 있는 미생물에 산소를 공급해 줌으로써 미생물의 활동이 활발히 진행되어 호수의 자정작용이 활발히 일어나게 된다. Rainwater introduced into the oxygen dissolving unit 170 supplies oxygen to the microorganisms in the lake, thereby actively promoting the activity of the microorganisms, and thus, self-cleaning of the lake occurs.

우수는 2차적으로 최종방류구에 설치된 상기 배출부(180)의 여재를 거쳐 PO4-P(인산염인)와 N(질소)이 제거된 후 최종 방류수로 배출된다. Rainwater is discharged to the final effluent after the removal of PO 4 -P (phosphate) and N (nitrogen) through the media of the discharge unit 180 installed in the final outlet.

본 발명을 통하여 초기 강우시 농약, 비료 등의 침출수 유입 및 낙엽부패물, 비점오염물질 유입 등과, 오수처리수 등의 유입으로 인한 수질악화를 방지하고, 부영양화로 인한 녹조현상이 발생할 수 있다.The present invention prevents water deterioration due to inflow of leachate and deciduous debris, nonpoint pollutants, etc., and inflow of sewage treatment water during the initial rainfall, and may cause green algae due to eutrophication.

따라서, 악취 및 해충의 발생도 억제될 수 있어서, 상기 조경요소로써의 기능을 충실히 수행할 수 있다.Therefore, the occurrence of odor and pests can also be suppressed, so that the function as the landscaping element can be faithfully performed.

또, 설치공간이 적어서, 소규모의 저류지에도 본 발명을 적용할 수 있다.Moreover, since the installation space is small, the present invention can be applied to a small reservoir.

그리고, 버려지는 패각을 재활용하여 여재로써 사용함으로써 환경보전에 도움이 될 뿐 아니라, 호수의 물에 용존된 인 또는 질소를 제거할 수 있다.In addition, the discarded shells can be recycled and used as media to help preserve the environment and to remove dissolved phosphorus or nitrogen in the lake water.

따라서, 일반적으로 부영양화 현상을 일으키는 물질의 제한 영양소로 작용하고 있는 질소와 인을 제거함으로써 수중의 부영양화 현상을 방지할 수 있다. Therefore, it is possible to prevent eutrophication in water by removing nitrogen and phosphorus which act as limiting nutrients of substances causing eutrophication generally.

또한, 본 장치는 1차와 2차의 세라믹화한 여재층에 우수를 통과시킴으로써 질소와 인 제거효율을 극대화 시켰다. In addition, the device maximizes nitrogen and phosphorus removal efficiency by passing rainwater through the first and second ceramic media layers.

그리고, 상기 여재는 세수 후 건조시키는 간단한 청소과정을 거친 후 재사용할 수 있어서 본 발명은 자원의 절약 측면에서도 장점을 가지고 있다. In addition, the filter medium can be reused after a simple cleaning process to dry after washing the present invention has an advantage in terms of saving resources.
