도면을 참조하여 본 발명을 상세히 설명하기로 한다. 도1은 본 발명에 따른 공기접촉생물막과 침지생물막을 이용한 오폐수처리장치를 나타내는 구성도 이다.The present invention will be described in detail with reference to the drawings. 1 is a block diagram showing a wastewater treatment apparatus using an air contact biofilm and an immersion biofilm according to the present invention.
본 발명에 따른 공기접촉생물막과 침지생물막을 이용한 오폐수처리장치는 기존의 오폐수처리장치에서 채택하고 있는 폐수처리장치, 다단폐수처리장치, 자연포기에 의한 다단식 생물막 접촉장치 등의 장점을 모두 취하고, 그 단점을 개선하기 위해 공기접촉생물막과 침지생물막을 동시에 채택하고 있다.The wastewater treatment apparatus using the air contact biofilm and the immersion biofilm according to the present invention takes all the advantages of the wastewater treatment apparatus, the multi-stage wastewater treatment apparatus, and the multistage biofilm contact apparatus using natural aeration, which are adopted in the conventional wastewater treatment apparatus, and In order to improve the disadvantage, air contact biofilm and immersion biofilm are adopted at the same time.
다시 말하면, 본 발명에 따른 오폐수처리장치에서 생물막반응조(12)에 공기접촉생물막과 침지생물막이 구성되어 있다. 이때 공기접촉생물막(2)과 침지생물막(3)에는 기존에 상용되고 있는 접촉여재 즉, 0.1mm이하의 실이 4cm크기로 가지처럼 늘어지게 형성된 긴줄의 형태에 생물막을 형성시키게 된다. 공기접촉여재는 매달수 있는 형태면 로프형, 삼각형등 형태에 구애받지 않으며 재질도 폴리에틸렌(FE), 포리프로필렌(PP)등 내구성만 있다면 어느 것이든 여러 가지를 사용 할 수도 있다.In other words, in the wastewater treatment apparatus according to the present invention, an air contact biofilm and an immersion biofilm are formed in the biofilm reaction tank 12. In this case, the air contact biofilm 2 and the immersion biofilm 3 form a biofilm in the form of a long string in which a contact material, that is, conventionally used, that is, 0.1 mm or less, is stretched like a branch with a size of 4 cm. Air contact media can be suspended in any form of rope, triangle, etc., and materials can be used as long as they have durability such as polyethylene (FE) and polypropylene (PP).
그리고, 생물막반응조(12)에서 공기접촉생물막(2)과 침지생물막(3)을 거친 정화폐수를 수집하여 침전조(8)로 낙하시키게 된다.In addition, the biofilm reaction tank 12 collects the purified wastewater passing through the air contact biofilm 2 and the immersion biofilm 3 and falls to the settling tank 8.
여기서, 생물막반응조(12)의 하부에 위치하도록 설치되는 침전조(8)에는 오폐수중의 슬러지가 자연 침천되면서 슬러지배출배관(7)을 통해 외부로 배출되도록 구성되고 오폐수수집조(15)의 오폐수는 오폐수공급배관(4)을 통해 생물막반응조(12)에 공급되도록 구성되어 있다.Here, the sedimentation tank (8) installed to be located under the biofilm reaction tank (12) is configured to be discharged to the outside through the sludge discharge pipe (7) as the sludge in the waste water is naturally precipitated and the waste water of the wastewater collection tank (15) It is configured to be supplied to the biofilm reaction tank 12 through the waste water supply pipe (4).
특히, 어느정도 슬러지 침전이 이루어지거나 생물막반응조(12)를 거치면서 정화된 침전조(8)의 상등수는 순환펌프(9)의 펌핑작용에 의해 제1,2순환배관(13,5)을 통해 노즐배관(1)으로 압송되어지게 된다.In particular, the sludge settled to some extent or the supernatant of the settling tank 8 purified through the biofilm reaction tank 12 is pumped through the first and second circulation pipes 13 and 5 by the pumping action of the circulation pump 9. It is pushed to (1).
또한, 침전조(8)에 담겨지는 오폐수중 침전에 의한 슬러지제거와 생물막반응조(12)의 반복적인 순환에 의해 정화 처리된 상등수는 월류벽(11)을 통해 오버플로(Overflow)되어 월류조(6)에 담겨진 다음, 다시 월류수배관(6-1)을 통해 최종적으로 정화된 상태로 배출이 이루어지게 된다.In addition, the supernatant purified by the sludge removal due to sedimentation in the wastewater contained in the sedimentation tank 8 and the repetitive circulation of the biofilm reaction tank 12 is overflowed through the overflow wall 11 so as to overflow the overflow tank 6 ), And then discharged to the final purified state through the overflow pipe (6-1).
특히, 침전조(8)내의 오폐수는 월류수배관(6-1)을 통해 최종적으로 배출되는 과정까지 침전과 순화정화과정에서 순환비를 조절하여 혐기성, 호기성을 조절할수 있다.In particular, the wastewater in the sedimentation tank (8) can be controlled anaerobic, aerobic by controlling the circulation ratio in the precipitation and purification process until the final discharge through the overflow water pipe (6-1).
그리고, 생물막반응조(12)의 상부에 설치되는 노즐배관(1)은 제2순환배관(5)과 오폐수공급배관(4)을 통해 압송되는 순환폐수를 다수의 노즐(1-1)을 통해 생물막반응조의 상부로 살수하게 된다.In addition, the nozzle pipe 1 installed at the upper portion of the biofilm reaction tank 12 includes the biofilm through the plurality of nozzles 1-1 through the plurality of nozzles 1-1 for the circulating wastewater being pumped through the second circulation pipe 5 and the wastewater supply pipe 4. It will be sprayed to the top of the reactor.
또한 침전조(8)내에 침지되어 있는 침지생물막(3)은 생물막이 수중에 위치하고 있으나 침전조(8)내의 DO농도가 높아 처리효율이 증대된다.In addition, the immersion biofilm 3 immersed in the settling tank 8 is located in the water, but the bioconcentration in the settling tank 8 has a high DO concentration, the treatment efficiency is increased.
기존의 처리장치는 침전조의 높은 DO농도를 활용하지 못했으나 본장치는 여재의 일부를 침전조에 침지하므로 잔류 DO농도를 최대로 활용하여 침지식 생물학적처리의 장점을 취해 처리효율이 증대되고 설비 및 운전면에서도 더욱 경제적이다.Existing treatment equipment did not utilize the high DO concentration in the sedimentation tank, but this apparatus immerses a part of the filter media in the sedimentation tank, thus taking advantage of the residual DO concentration to take advantage of the immersion type biological treatment to increase the treatment efficiency and increase equipment and operation. More economical in terms of
더욱이, 본 발명에 따른 공기접촉생물막과 침지생물막을 이용한 오폐수처리장치는 침전조(8)에서 유입오폐수와 순환오폐수의 혼합이 이루어지면서 공기접촉생물막에 부하가 되는 강한 유기물질의 농도를 희석할 수 있게 되고, 생화학적산소요구량의 부하량에 따른 관리가 용이하며, 유입오폐수의 수리적 부하율과 전단력을 증가시킴으로써 미생물점막을 계속적으로 탈리시키고, 미생물의 과도한 성장과 파리번식을 방지할 수 있게 된다.Furthermore, the wastewater treatment apparatus using the air contact biofilm and the immersion biofilm according to the present invention is capable of diluting the concentration of the strong organic substance that is loaded on the air contact biofilm while the inflow waste water and the circulating waste water are mixed in the settling tank 8. In addition, it is easy to manage according to the load of biochemical oxygen demand, and it is possible to continuously detach the microbial mucosa by increasing the hydraulic load rate and the shear force of the influent wastewater, and to prevent the excessive growth of the microorganism and the reproduction of the fly.
또한, 발명에 따른 오폐수처리장치는 오폐수가 자연 낙하과정에서 정화함으로써 송풍기와 같은 산소공급장치가 불필요하게 된다.In addition, the wastewater treatment apparatus according to the present invention eliminates the need for an oxygen supply device such as a blower by purifying the wastewater in a natural fall process.
본 발명은 오폐수의 정화효율을 현저히 증대시키면서 콤팩트화를 이루어 설치부지를 최소화할 수 있고, 여재를 공기중에 노출시키고 또한 수중에 침지하여 처리성능을 향상시켜 고농도의 유입폐수도 처리가 가능하며, 오폐수가 자연 낙하과정에서 정화함으로써 송풍기와 같은 산소공급장치가 불필요한 효과를 제공하게 된다.The present invention can minimize the installation site by making the compactness while significantly increasing the purification efficiency of waste water, improve the treatment performance by exposing the media in the air and immersed in water, and also it is possible to treat influent wastewater of high concentration, waste water By purifying in the natural fall process, oxygen supply devices such as blowers provide unnecessary effects.
