Description

TOC저감 수처리장치{Water treatment apparatus for reduction}TOC reduction water treatment apparatus {Water treatment apparatus for reduction}

본 발명은 TOC저감 수처리장치에 관한 것으로서, 보다 상세하게는 수중에 자외선을 조사하는 종래 TOC저감 수처리장치에 비해 상대적으로 높은 유기물의 분해효율을 기대할 수 있는 새로운 구성의 TOC저감 수처리장치에 관한 것이다. The present invention relates to a TOC-reducing water treatment device, and more particularly, to a TOC-reducing water treatment device with a novel configuration that can expect a relatively high organic matter decomposition efficiency compared to conventional TOC-reducing water treatment devices that irradiate ultraviolet rays into water.

수중의 TOC(Total Organic Carbon, 총유기탄소) 농도를 감소시키는 방법으로 자외선램프를 이용한 자외선 산화처리방법이 사용되고 있다. 자외선 산화처리방법은 피처리수가 유입되는 반응조 내부에 자외선 램프가 설치되어 이루어지는 자외선 산화장치를 이용하여 행해지는데, 반응조 내에 유입된 피처리수에 자외선을 조사하면, 물이 산화분해되어 OH라디칼이 생성되고, 이 OH라디칼이 산화제로서의 기능을 하여 유기물이 이산화탄소와 유기산으로 산화분해된다.As a method of reducing TOC (Total Organic Carbon) concentration in water, an ultraviolet oxidation treatment method using an ultraviolet lamp is used. The UV oxidation treatment method is performed using an ultraviolet oxidizing device in which an ultraviolet lamp is installed inside the reaction tank into which the water to be treated flows. This OH radical functions as an oxidizing agent, and organic matter is oxidatively decomposed into carbon dioxide and organic acid.

이러한 자외선 산화처리방법에서 유기물의 분해효율을 높여서 TOC를 요구되는 수준으로 낮추기 위해서는 자외선 조사량을 높일 필요가 있다. 그런데 종래의 자외선 산화처리장치는 자외선램프가 반응조의 수중에 위치되도록 설치되어 자외선이 수중에 조사되기 때문에 수중에서 자외선의 투과율이 감소되어 유기물에 조사되는 자외선의 강도가 저하되며, 따라서 유기물의 분해효율이 감소되는 문제가 발생된다. 따라서 유기물의 분해효율을 높이기 위해 자외선이 과잉 조사되도록 설정되어야 하며, 이를 위해서는 조사량이 큰 자외선램프를 사용하여야 할 뿐만 아니라 자외선 램프를 자주 교체하여야 하므로 운영비용이 증가되는 문제를 가진다. In this UV oxidation treatment method, it is necessary to increase the amount of UV irradiation in order to lower the TOC to a required level by increasing the decomposition efficiency of organic matter. However, in the conventional ultraviolet oxidation treatment device, the ultraviolet lamp is installed in the water of the reaction tank so that the ultraviolet light is irradiated into the water, so the transmittance of the ultraviolet light in the water is reduced and the intensity of the ultraviolet light irradiated to the organic material is lowered, and thus the decomposition efficiency of the organic material is reduced. This reduction problem arises. Therefore, in order to increase the decomposition efficiency of organic substances, UV rays must be set to be excessively irradiated, and for this, a UV lamp with a large irradiation amount must be used and the UV lamp must be frequently replaced, which increases operating costs.

본 발명의 다른 특징에 따르면, 상기 타공 케이스(220)는 바아형태를 가지며, 상기 승강수단(300)은 상호 이격되도록 상기 반응조(100) 내부에 설치되어, 상기 흡착모듈(200)의 길이방향 양단부가 각각 결합되는 한 쌍의 체인(310); 상기 체인(310)들이 반응조(100)에 유입된 피처리수에 침지된 후 피처리수 수면 위로 부상되고, 다시 피처리수에 침지되는 무한궤도를 가지도록 상기 체인(310)들을 안내하는 복수개의 스프라켓(320); 및 상기 스프라켓(320)을 구동시키는 구동모터(330);를 포함한다.According to another feature of the present invention, the perforated case 220 has a bar shape, and the lifting means 300 are installed inside the reaction tank 100 so as to be spaced apart from each other, and both ends of the absorption module 200 in the longitudinal direction.

이상과 같은 구성을 가지는 본 발명은 광촉매가 함유된 흡착볼이 수중에 침지되면 피처리수 중의 유기물이 흡착볼에 흡착되고, 흡착볼을 수면 위로 부상되면 자외선이 조사되어 흡착볼에 함유된 광촉매의 광촉매작용이 활성화되어 흡착볼에 흡착된 유기물이 산화되어 분해된다.

이하에서 본 발명을 좀 더 구체적으로 설명한다. Hereinafter, the present invention will be described in more detail.

도 1 내지 도 3은 본 발명의 바람직한 실시예를 보인 도면이다. 본 발명은 도시된 바와 같이, 피처리수가 처리되는 반응조(100)와, 흡착볼(210)이 타공 케이스(220)에 수용되어 이루어진 복수개의 흡착모듈(200)과, 흡착모듈(200)이 탑재된 승강수단(300)과, 자외선램프(400)를 포함한다.1 to 3 are views showing a preferred embodiment of the present invention. As shown in the drawing, the present invention includes a reaction tank 100 in which water to be treated is treated, a plurality of adsorption modules 200 in which adsorption balls 210 are accommodated in a perforated case 220, and an adsorption module 200. It includes an elevating means 300 and an ultraviolet lamp 400.

상기 반응조(100)는 피처리수가 처리되어 외부로 배출되는 공간으로서, 일측에는 피처리수가 유입되는 피처리수유입구(110)가 형성되고 타측에는 처리된 처리수가 배출되는 처리수배출구(120)가 형성되며, 상측에는 반응조(100)의 내부 온도가 과도하게 상승되는 것을 방지하기 위해 반응조(100) 내부 공기를 외부로 배기시키는 배기펌프(130)가 설치된다. 상기 피처리수유입구(110) 및 처리수배출구(120)에는 피처리수 및 처리수의 유입 및 배출을 차단하기 위한 개폐수단이 구비된다. 미 설명부호 140은 수처리장치의 점검시 작업자의 이동 및 안전을 위해 마련된 워크웨이이다. The reaction tank 100 is a space where untreated water is treated and discharged to the outside, and an untreated water inlet 110 through which untreated water flows in is formed on one side and a treated water outlet 120 through which the treated water is discharged on the other side. An exhaust pump 130 is installed on the upper side to exhaust the air inside the reaction tank 100 to the outside in order to prevent the internal temperature of the reaction tank 100 from excessively rising. Opening/closing means for blocking the inflow and discharge of the water to be treated and the water to be treated are provided at the inlet 110 and the outlet 120 for the water to be treated. US explanatory numeral 140 is a walkway provided for the movement and safety of workers when inspecting the water treatment device.

상기 흡착모듈(200)은 흡착볼(210)이 타공 케이스(220)에 수용되어 이루어진다. 상기 흡착볼(210)은 무기흡착제와 광촉매의 혼합물을 볼형상으로 성형한 것이다. 무기흡착제로는 제올라이트, 실리카, 알루미나 등이 사용되며, 광촉매로는 이산화티탄, 산화아연, 산화지르코늄 등이 사용된다. 바람직하게는 무기흡착제로는 제올라이트가 사용되고, 광촉매로는 이산화티탄이 사용되는데, 본 실시예에서는 흡착볼(210)이 제올라이트 90중량%, 이산화티탄 10중량%로 이루어진 것으로 예시된다. The adsorption module 200 is formed by accommodating the adsorption ball 210 in the perforated case 220 . The adsorption ball 210 is formed by molding a mixture of an inorganic adsorbent and a photocatalyst into a ball shape. Zeolite, silica, alumina, etc. are used as inorganic adsorbents, and titanium dioxide, zinc oxide, zirconium oxide, etc. are used as photocatalysts. Preferably, zeolite is used as the inorganic adsorbent and titanium dioxide is used as the photocatalyst.

그리고 타공 케이스(220)는 흡착볼(210)이 수용되는 케이스로서, 내부로 피처리수가 유입되도록 타공이 형성된다. 본 실시예에서는 타공 케이스(220)가 상부가 개방된 사각바아형태의 케이스본체(222)와, 케이스본체(222)의 상부를 커버하는 뚜껑(224)으로 이루어지며, 케이스본체(222)의 길이방향 양단부에는 상기 승강수단(300)에 탑재시키기 위한 연결플랜지(223)가 돌출형성된 것으로 예시되었다. 본 실시예에서는 타공 케이스(220)가 사각바아형태를 가지는 것으로 예시되었으나, 타공케이스(220)의 형태가 이에 국한되지 않음은 당연하다.The perforated case 220 is a case in which the suction balls 210 are accommodated, and perforations are formed so that the water to be treated flows into the case. In this embodiment, the perforated case 220 is composed of a case body 222 in the form of a square bar with an open top and a lid 224 covering the upper portion of the case body 222, and the length of the case body 222 At both ends in the direction, connection flanges 223 for mounting on the lifting means 300 are exemplified as being protrudingly formed. In this embodiment, although the perforated case 220 is illustrated as having a square bar shape, it is natural that the shape of the perforated case 220 is not limited thereto.

후술하는 바와 같이, 흡착볼(210)이 수용된 흡착모듈(200)이 피처리수에 침지되면, 피처리수에 함유된 유기물이 흡착볼(210)에 흡착되고, 유기물이 흡착된 흡착볼(210)에 자외선이 조사되면 광촉매의 광촉매작용이 활성화되어 흡착볼(210)에 흡착된 유기물이 산화되어 분해된다. As will be described later, when the adsorption module 200 in which the adsorption ball 210 is accommodated is immersed in the water to be treated, the organic matter contained in the water to be treated is adsorbed to the adsorption ball 210, and the adsorption ball 210 to which the organic matter is adsorbed ) is irradiated with ultraviolet rays, the photocatalytic action of the photocatalyst is activated, and the organic matter adsorbed on the adsorption ball 210 is oxidized and decomposed.

한편, 상기 승강수단(300)은 흡착모듈(200)을 피처리수 중에 침지시키거나 피처리수의 수면 위로 부상시키기 위한 것이다. 본 실시예에서는 승강수단(300)이 상기 흡착모듈(200)의 양측 단부가 결합되는 한 쌍의 체인(310)과, 이 체인(310)들을 무한궤도를 가지도록 이동시키는 복수개의 스프라켓(320)과, 스프라켓(320)들을 구동시키는 구동모터(330)로 이루어진 것으로 예시되었다.On the other hand, the lifting means 300 is for immersing the adsorption module 200 in the water to be treated or floating it on the surface of the water to be treated. In this embodiment, the lifting means 300 includes a pair of chains 310 to which both ends of the adsorption module 200 are coupled, and a plurality of sprockets 320 for moving the chains 310 to have an endless track. And, it has been illustrated as consisting of a drive motor 330 for driving the sprocket 320.

상기 체인(310)들은 반응조(100)의 전후 또는 좌우 내측면에 근접되도록 상호 대향되게 설치되는데, 체인(310)에는 흡착모듈(200)에 구비된 연결플랜지(223)가 결합되는 브라켓(312)들이 일정간격으로 구비되어, 흡착모듈(200)들이 상기 브라켓(312)을 통해 상호 나란하도록 체인(310)에 탑재된다.The chains 310 are installed facing each other so as to be close to the front and rear or left and right inner surfaces of the reaction tank 100, and to the chain 310, a bracket 312 to which the connection flange 223 provided in the adsorption module 200 is coupled are provided at regular intervals, and the adsorption modules 200 are mounted on the chain 310 so as to be parallel to each other through the brackets 312.

이러한 한 쌍의 체인(310)은 상기 스프라켓(320)들에 의해 반응조(100) 하측에서 반응조(100) 상측으로 상승된 후 다시 하강하는 무한궤도를 가지는데, 이 무한궤도 중의 일부는 수면 위로 부상되고 나머지는 수중에 침지되도록 스프라켓(320)의 위치가 조절된다. The pair of chains 310 have an endless track that rises from the lower side of the reaction tank 100 to the upper side of the reaction tank 100 by the sprockets 320 and then descends again, and some of these endless tracks rise to the surface of the water. and the position of the sprocket 320 is adjusted so that the rest is immersed in water.

좀 더 구체적으로는 체인(310)이 이동되는 궤도는 피처리수에 침지되어 상승되는 상승구간과, 상승구간 상단에 연결되어 피처리수 수면 위로 부상된 상태에서 상기 자외선램프(400) 하측에서 반응조(100) 일측에서 타측으로 수평이동되는 수평이동구간과, 상단부는 상기 수평이동구간에 연결되고 하단부는 상승구간 하단부에 연결되어 피처리수로 다시 침지되는 하강구간으로 이루어진다. 체인(310)이 이러한 무한궤도를 가짐에 따라 체인(310)에 탑재된 흡착모듈(200)의 이동경로 역시 피처리수에 침지되어 상승되는 상승경로, 수면 위로 부상되어 수평으로 이동되는 수평이동경로, 다시 피처리수에 침지되는 하강경로로 이루어진다. More specifically, the track on which the chain 310 moves is connected to the rising section where it is immersed in the water to be treated and raised, and the upper end of the rising section is connected to the water surface to be treated, and the reaction tank is located below the UV lamp 400 in a state of floating above the surface of the water to be treated. (100) It consists of a horizontal movement section that moves horizontally from one side to the other side, and a descending section that is connected to the horizontal movement section at the upper end and connected to the lower end of the rising section to be immersed again in the water to be treated. As the chain 310 has such an endless track, the moving path of the adsorption module 200 mounted on the chain 310 is also an ascending path immersed in the water to be treated and raised, and a horizontal moving path floating above the water surface and moving horizontally , consists of a descending path that is immersed in the water to be treated again.

바람직하게는 도시된 바와 같이, 상기 상승구간은 지그재그형태로 이루어지는데, 이에 따라 흡착모듈(200)이 수중에 침지된 상태에서 지그재그 경로로 상승되기 때문에 흡착모듈(200)들이 수중에 침지되는 시간을 충분히 확보하게 되어 수중의 유기물이 흡착볼(210)에 흡착되는 흡착효율이 향상된다. 그리고 체인(310)이 수면 위로 부상된 상태에서 반응조(100)의 일측에서 타측으로 수평이동되는 구간(수평이동구간)에서 자외선이 흡착볼(210)에 조사되기 때문에 후술하는 바와 같이, 흡착볼(210)에 흡착된 유기물에 자외선이 충분히 조사되어 유기물의 산화효율이 향상된다. Preferably, as shown, the ascending section is formed in a zigzag shape. Accordingly, since the adsorption module 200 rises in a zigzag path while immersed in water, the time during which the adsorption modules 200 are immersed in water is shortened. This is sufficiently secured to improve the adsorption efficiency in which organic matter in the water is adsorbed to the adsorption ball 210. In addition, since ultraviolet rays are irradiated to the adsorption ball 210 in a section (horizontal movement section) in which the chain 310 is horizontally moved from one side to the other side of the reaction tank 100 while floating on the surface of the water, as will be described later, the adsorption ball ( 210) is sufficiently irradiated with ultraviolet rays to improve the oxidation efficiency of the organic matter.

본 실시예에서는 승강수단(300)이 한 쌍의 체인(310)과, 이 체인(310)들을 이동시키는 스프라켓(320)과, 스프라켓(320)을 구동시키는 구동모터(320)로 이루어진 것으로 예시되었으나, 승강수단(300)은 이에 국한되지 않고 흡착모듈(200)들을 탑재하여 수중에 침지시킨 후 수면 위로 부상시키는 과정을 반복할 수 있는 어떠한 구성으로도 변형이 가능하다. In this embodiment, the lifting means 300 is illustrated as consisting of a pair of chains 310, sprockets 320 for moving the chains 310, and a drive motor 320 for driving the sprockets 320. , The lifting means 300 is not limited thereto, and can be modified into any configuration capable of repeating the process of mounting the adsorption modules 200, immersing them in water, and then floating them on the surface of the water.

그리고 상기 자외선램프(400)는 상기 체인(300)의 궤도, 즉, 흡착모듈(200)의 이동경로 상부에 위치되도록 반응조(100) 내부 상측에 설치되어, 하향으로 자외선을 조사한다. The UV lamp 400 is installed on the upper side of the inside of the reaction tank 100 so as to be located above the trajectory of the chain 300, that is, the moving path of the adsorption module 200, and irradiates ultraviolet rays downward.

이와 같은 구성을 가지는 본 발명은 상기 반응조(100)로 피처리수가 유입되면 승강수단(300)이 작동되어 승강수단(300)에 탑재된 흡착모듈(200)이 이동되고, 자외선램프(400)가 작동된다. 흡착모듈(200)은 승강수단(300)에 의해 피처리수에 침지되어 상승되는 상승경로, 수면 위로 부상되어 반응조 일측에서 타측으로 수평이동되는 수평이동경로, 다시 수중으로 침지되는 하강경로로 이동되는데, 흡착모듈(200)이 수중에 침지되어 이동되는 과정에서 피처리수에 함유된 유기물이 흡착볼(210)에 흡착된다.In the present invention having such a configuration, when the water to be treated flows into the reaction tank 100, the elevating means 300 is operated, the adsorption module 200 mounted on the elevating means 300 is moved, and the ultraviolet lamp 400 is moved. It works. The adsorption module 200 is immersed in the water to be treated by the elevating means 300 and moved up, a horizontal movement path floating on the water surface and horizontally moving from one side of the reaction tank to the other side, and a descending path immersed in water again. , Organic matter contained in the water to be treated is adsorbed to the adsorption ball 210 while the adsorption module 200 is immersed in water and moved.

그리고 흡착모듈(200)이 수면 위로 부상되어 수평으로 이동되는 과정에서 흡착볼(210)에 자외선이 조사되면, 흡착볼(210)의 광촉매작용이 활성화되어 흡착볼(210)에 흡착된 유기물이 산화되어 분해된다. 물론, 자외선이 하향으로 조사되기 때문에 자외선이 피처리수에도 조사되어 피처리수 중의 일부 유기물은 수중에서 자외선에 의해 산화된다. In addition, when the adsorption ball 210 is irradiated with ultraviolet rays while the adsorption module 200 floats on the surface of the water and moves horizontally, the photocatalytic action of the adsorption ball 210 is activated and the organic matter adsorbed on the adsorption ball 210 is oxidized. become and disintegrate Of course, since the ultraviolet rays are irradiated downward, the ultraviolet rays are also irradiated to the water to be treated, and some organic substances in the water to be treated are oxidized by the ultraviolet rays in the water.

이와 같이 본 발명은 피처리수 중의 유기물을 광촉매가 함유된 흡착볼에 흡착되고 유기물이 흡착된 흡착볼을 수면 위로 부상된 상태에서 자외선이 조사되기 때문에, 종래 수중에 자외선이 조사되어 자외선이 투과율이 감소되는 종래의 TOC저감장치와 달리 자외선의 투과율이 감소되지 않고 자외선이 강한 강도로 흡착볼에 조사되므로 종래 TOC저감 수처리장치에 비해 상대적으로 높은 유기물의 분해효율을 기대할 수 있다. As described above, in the present invention, organic matter in the water to be treated is adsorbed to the adsorption ball containing the photocatalyst, and ultraviolet rays are irradiated while the organic matter adsorbed adsorption ball is floated on the surface of the water. Unlike the conventional TOC reduction device, which is reduced, the transmittance of ultraviolet rays is not reduced and the ultraviolet rays are irradiated to the adsorption ball with strong intensity, so a relatively high organic matter decomposition efficiency can be expected compared to the conventional TOC reduction water treatment device.
