도 1은 본 발명에 따른 지하수의 유기오염물질 제거장치를 도시한 개략도이다.1 is a schematic diagram showing an apparatus for removing organic pollutants in groundwater according to the present invention.
본 발명에 따른 지하수의 오염물질 제거장치(1)는 도 1에 도시한 바와같이, 지하수의 오염물질중 대부분을 차지하는 유기오염물질을 지하수 관리 및 감시를 위하여 지하에 수직하게 삽입되어 설치되고, 내부벽에 유기오염물질을 분해하는데 탁월한 성능을 갖는 광촉매 물질을 도포한 관측관(10)과, 상기 관측관(10) 내부에서 유기오염물질의 분해가 촉진되도록 자외선을 인위적으로 조사하는 자외선 램프(20)로 이루어져있다.Groundwater contaminant removal device 1 according to the present invention, as shown in Figure 1, the organic contaminants that occupy most of the contaminants in the groundwater is installed vertically inserted into the basement for underground water management and monitoring, the inner wall An observation tube (10) coated with a photocatalytic material having excellent performance in decomposing organic pollutants, and an ultraviolet lamp (20) which artificially irradiates ultraviolet rays to promote decomposition of organic pollutants in the observation tube (10). Consists of
상기 관측관(10)은 지하수나 토양의 오염정도를 감시하기 위해서 삽입되는 중공형의 파이프부재이고, 지하수와 접하는 외부면에는 입자가 큰 불순물을 제외한 지하수만을 관내부로 유입시킬 수 있도록 통과스크린(12)을 형성하고, 지하수가 채워지는 관내부면에는 유입된 지하수가 상승하는 수두높이만큼 지하수내에 함유된 유기오염물질을 분해하는데 탁월한 성능을 갖는 광촉매를 통상의 졸겔법으로 도포하는 한편, 상기 관측관(10) 내부로 유입된 지하수의 수두부근에는 관내부에서 유기오염물질을 제거한 지하수가 외부로 유출되는 토출구(14)를 형성하며, 상기 토출구(14)에는 유기오염물질이 제거된 지하수를 2차로 여과할 수 있도록 상기 통과스크린의 통과공보다 작은 구멍을 갖는 보조스크린(미도시)을 설치한다.The observation tube 10 is a hollow pipe member inserted to monitor the degree of contamination of the groundwater or soil, the outer screen in contact with the groundwater through the screen 12 so that only the groundwater, except for impurities large particles can be introduced into the tube. ) And a photocatalyst having excellent performance in decomposing organic pollutants contained in the groundwater by the head height at which the groundwater flows up is applied to the inner surface of the tube filled with groundwater by the conventional sol-gel method. 10) near the head of the groundwater introduced into the interior of the head to form a discharge port 14, the groundwater from which the organic contaminant is removed from the inside of the pipe flows to the outside, and the discharge hole 14 is filtered through the groundwater from which the organic pollutant is removed An auxiliary screen (not shown) having a hole smaller than the through hole of the passing screen is installed to be able to do so.
여기서, 상기 관측관(10)은 내산성 및 광촉매의 도포가 용이한 스테인레스 재질의 중공형관부재로 구성되며, 상기 광촉매는 관측관(10) 내부면에 200Å 내지 1㎛ 의 두께로 도포되고, 지하수를 관측관(10) 내부로 통과시키도록 이에 형성되는 통과스크린(12)은 관측관(10)을 제작하는 제작과정에서 만들어진다.Here, the observation tube 10 is composed of a stainless steel hollow tube member that is easy to apply acid resistance and photocatalyst, the photocatalyst is applied to the inner surface of the observation tube 10 to a thickness of 200 ~ 1㎛, groundwater Passing screen 12 formed therein so as to pass through the observation tube 10 is made in the manufacturing process of manufacturing the observation tube (10).
또한, 지하수가 일정높이 채워진 상기 관측관(10) 내부에 설치되는 자외선램프(20)는 광촉매에 의한 유기오염물질의 분해성능을 촉진시키도록 조도 20W 내외의 자외선을 조사하는 램프부재이며, 자외선의 발광이 연속적으로 이루어지도록 전원 케이블을 매개로 지표면에 설치되는 동력원(22)과 전기적으로 연결되며, 하단에는 관내에 차있는 지하수의 부력에 의해서 상부로 상승되어 노출되지 않고, 일정깊이 잠수된 상태를 유지할 수 있도록 일정무게를 갖는 무게추(24)가 매달려진다.In addition, the ultraviolet lamp 20 installed inside the observation tube 10 filled with ground water at a predetermined height is a lamp member that irradiates ultraviolet rays within 20 W of illumination intensity to promote decomposition performance of organic pollutants by photocatalysts. It is electrically connected to the power source 22 installed on the ground surface through the power cable so that light emission is continuously performed. At the lower end, it is raised to the upper side by buoyancy of groundwater filled in the pipe and is not exposed. A weight 24 having a constant weight is suspended to maintain it.
상기와 같이 광촉매 물질을 내부면에 도포하고, 통과스크린(12)과 토출구(14)를 형성한 관측관(10)을 지하수가 오염된 오염지역에 일정깊이 삽입하여 수직설치하면, 유기오염물질을 포함하는 지하수는 상기 관측관(10) 내부로 상기 통과스크린(12)을 통하여 흘러들어와 수두높이만큼 채워지게 된다.When the photocatalyst material is applied to the inner surface as described above, and the observation tube 10 formed with the passage screen 12 and the discharge port 14 is vertically inserted into the contaminated area where the groundwater is contaminated, organic contaminants are formed. Including groundwater flows through the passage screen 12 into the observation tube 10 to be filled by the head height.
이때, 지상에 설치된 동력원(22)을 작동시켜 이와 전기적으로 연결되어 있는 자외선램프(20)를 점등시키면, 상기 관측관(10)내에 채워진 지하수에 상부가 노출되지 않도록 일정깊이 잠수된 자외선 램프(20)로부터 발광되는 자외선이 광촉매에 직접적으로 조사되기 때문에, 오염유기물질을 분해하는 광촉매를 활성화시켜 분해능을 향상시킨다.At this time, by operating the power source 22 installed on the ground to turn on the ultraviolet lamp 20 that is electrically connected thereto, the ultraviolet lamp 20 submerged deeply so that the upper part is not exposed to the groundwater filled in the observation tube (10) Since the ultraviolet light emitted from the UV light is directly irradiated to the photocatalyst, the resolution is improved by activating the photocatalyst for decomposing contaminated organic substances.
그리고, 상기 광촉매에 의해서 일단 분해된 유기물을 포함한 지하수는 관측관(10)의 관내 수두에 의해서 일정수두까지 상승하게 되고, 유기오염물질이 분해된 지하수는 수두부근에 형성된 토출구(14)를 통하여 관외부로 배출된다. 이때, 상기 토출구(14)에는 별도의 보조스크린(미도시)이 설치됨에 따라 오염유기물이 제거된 지하수에 함유된 다른 유기물이 관외부로 배출되는 것을 방지한다.In addition, the groundwater including the organic matter once decomposed by the photocatalyst rises to a certain head by the head of the pipe in the observation tube 10, and the groundwater from which the organic pollutant is decomposed is discharged through the discharge port 14 formed near the head. It is discharged to the outside. In this case, as a separate auxiliary screen (not shown) is installed in the discharge port 14, other organic substances contained in the groundwater from which the contaminated organic matter is removed are prevented from being discharged to the outside of the tube.
상술한 바와같은 본 발명에 의하면, 일정수두높이까지 지하수가 유입되는 관측관(10) 내부에 유기오염물질을 분해하는 능력이 우수한 광촉매를 도포하고, 오염물질의 분해능이 촉진되도록 자외선을 조사하는 자외선램프(20)를 관측관(10) 내부에 설치함으로써, 지하수가 오염된 지역의 오염원을 분해하여 제거할 수 있기 때문에, 종래와 같이 생물학적, 화학적 및 물리적 처리방법을 이용하는 경우보다 비용이 저렴하고 신속하게 대상 오염물질을 제거할 수 있는 효과가 얻어진다.According to the present invention as described above, by applying a photocatalyst having an excellent ability to decompose organic pollutants in the observation tube 10 inside the groundwater flows up to a certain head height, ultraviolet rays irradiated with ultraviolet rays to promote the resolution of contaminants By installing the lamp 20 inside the observation tube 10, since the groundwater can be decomposed and removed from the polluted area, it is cheaper and faster than conventional biological, chemical and physical treatment methods. The effect of removing the pollutants of interest is obtained.
그리고, 상기 관측관(10)을 지하수 오염물질의 오염정도의 복원상태를 조사할 수 있는 용도로도 사용할 수 있는 효과가 있다.In addition, there is an effect that the observation tube 10 can also be used for the purpose of investigating the restoration state of the pollution degree of groundwater contaminants.
