본 발명은 생활하수 및 산업폐수 등의 오, 폐수를 정화처리할 때 오,폐수의 생물학적 산소요구량(BOD)을 낮혀주는 호기성 미생물의 배양효율을 증대시킬 수 있는 오,폐수 정화처리용 미생물 배양장치에 관한 것이다.The present invention is a microorganism culture apparatus for wastewater purification treatment that can increase the cultivation efficiency of aerobic microorganisms to lower the biological oxygen demand (BOD) of the wastewater, when purification of wastewater, such as domestic sewage and industrial wastewater It is about.
일반적으로 생활하수 및 오수, 산업폐수 등에는 하천 또는 해안을 오염시키는 유기물질이 다량 함유되어 배출되고 있는데, 이러한 오,폐수속에 포함되어 있는 유기물질에 호기성 미생물을 배양하여 염기성 부패로 인한 악취발생이 억제되도록 고도의 처리를 하여야만 강물의 물고기가 떼죽음을 당하는 등 생활환경이 심각하게 오염되어 생태계가 점차 파괴되는 문제점을 해결할 수가 있어서 쾌적한 생활환경을 이룩할 수가 있다.In general, domestic sewage, sewage, and industrial wastewater contain and discharge a large amount of organic substances that pollute rivers or coasts, and odor generation due to basic decay is caused by culturing aerobic microorganisms in organic substances contained in such wastewater and wastewater. Only by high-level treatment to be suppressed, the river's fish are killed, so that the environment is seriously polluted and the ecosystem is gradually destroyed, thus achieving a pleasant living environment.
이에따라, 오,폐수의 정화처리를 하기위해 오,폐수의 정화처리 장치들이 많이 개발되고 있는 실정으로서, 그동안 개발된 오, 폐수 처리장치의 구성을 살펴보면 대개 오, 폐수속의 협잡물(SS)을 걸러주는 스크린조, 오,폐수를 부패시키는 혐기성 소화조 및 부패조, 여과석(토스톨)이 설치된 여과조 및 살수 여과상, 공기를 공급하여 호기성 생물을 배양하는 접촉산화조, 오니를 침강시키는 침전조, 정수된 물을 소독하여 방류하는 소독방류조로 구성되어 있다.Accordingly, in order to purify sewage and wastewater, a lot of sewage and wastewater treatment devices are being developed. Looking at the structure of the sewage and wastewater treatment devices developed in the meantime, it is generally used to filter out wastewater (SS). Screen tank, anaerobic digestion and decay tanks that rot wastewater, filtration tanks with filtration stones (tostol) and spraying filter beds, contact oxidation tanks that supply air to cultivate aerobic organisms, sedimentation tanks that settle sludge, purified water It consists of a disinfection discharge tank that disinfects and discharges water.
상기와 같은 구성에 의해 오,폐수의 정화처리를 할 때 오,폐수의 정화처리 효율은 접촉산화조에서, 오,폐수의 생물학적 산소요구량(BOD)을 낮혀주는 호기성 미생물의 배양을 얼마나 신속하게 많이 배양하느냐에 달려 있다고 할 수 있다.When the wastewater is purified by the above configuration, the efficiency of the wastewater purification treatment is how quickly the culture of aerobic microorganisms in the contact oxidation tank lowers the biological oxygen demand (BOD) of the wastewater. It can be said that it depends on the culture.
그런데 접촉산화조에서 호기성 미생물을 배양하는 종래의 기술을 살펴보면 구획칸이 넓고 배양실의 상,하부가 개방된 접촉재를 접촉산화조내의 오,폐수속의 적층시킨 상태에서, 또는 상기한 접촉재가 무작위로 담겨있는 접촉재통을 오,폐수속에 완전히 침강시킨 상태에서 에어공급관(9)을 통해 에어를 주입하여 호기성 미생물을 배양하고 있다.However, in the conventional technology of culturing aerobic microorganisms in a contact oxidizing tank, a contact compartment having a large compartment and an open upper and lower part of the culture chamber is laminated with wastewater and wastewater in the contact oxidizing tank, or the contacting agent is randomized. Air is injected through the air supply pipe (9) in the state in which the contained contact container is completely settled in the wastewater, and cultures aerobic microorganisms.
그러나 미생물 배양에 필요한 충분한 산소공급을 위해 에어공급관으로 고압의 많은 에어량을 주입할 경우에는 오,폐수가 심하게 유동됨에 따라 오,폐수에 잔존하고 있는 호기성 미생물이 접촉재에 잘 부착되지를 못함은 물론, 힘들게 달라붙은 미생물들도 쉽게 떨어지게 되는 문제점이 있으며, 이러한 문제점으로 인해 주입되는 에어량을 낮출경우에는 오,폐수속에 충분한 산소공급을 할 수가 없어서 미생물의 배양력이 떨어지는 문제점이 있다.However, when a large amount of high-pressure air is injected into the air supply pipe to supply sufficient oxygen for cultivation of microorganisms, aerobic microorganisms remaining in the wastewater and wastewater are not easily attached to the contact material as the wastewater flows heavily. , There is a problem that difficult to cling microorganisms easily fall off, and when the amount of air injected is lowered due to these problems, there is a problem that the culture capacity of the microorganism is reduced because sufficient oxygen cannot be supplied to the wastewater.
본 발명은 상기와 같은 종래의 여러 문제점들을 보안해주며 처리효율의 극대화를 이룰 수 있도록 한 것으로서, 특히 고도처리에 활용되는 회전원판 접촉법(R.B.R)과 유동층상 접촉산화조 및 회전산소 공급장치(ROTOR AERATOR)의 3가지의 장점만을 채택한 것이 본 발명의 가장 큰 특징이라고 할 수 있다.The present invention is to secure the various problems as described above and to maximize the processing efficiency, in particular the rotary disk contact method (RBR) and fluidized bed contact oxidation tank and rotary oxygen supply device (ROTOR) utilized in advanced processing Adopting only three advantages of the AERATOR) can be said to be the biggest feature of the present invention.
이러한 본 발명은 에어를 공급하더라도 접촉재에 붙어있는 미생물이 떨어지지 않고 효과적으로 많은량의 산소를 공급받아 보다 빠른시간내에 배양 효율을 최대한 높일 수 있는 장치를 제공하는데 그 목적이 있는 것으로서, 접촉재를 회전축과 조립하지 않고 유동상으로 폭기조에 충진하더라도 접촉재 형상의 특성으로 문제가 없도록 되어 있다.The present invention is to provide a device that can increase the cultivation efficiency as quickly as possible by receiving a large amount of oxygen effectively without a drop of microorganisms attached to the contact material even if air is supplied, the contact material is a rotating shaft Even if it is filled in the aeration tank in the fluidized bed without assembling with the assembly, there is no problem due to the characteristics of the contact member shape.
이하 본 발명을 바람직한 일실시예로서 첨부한 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as a preferred embodiment of the present invention.
바닥에 에어공급관(9)이 설치된 접촉산화조(1)내에 접촉재를 설치함에 있어서 수개의 핀축(3)이 환설된 회전체(2)를 모터(8)로 구동되게 접촉산화조(1)내에 설치하고 회전체(2)의 각 핀축(3)마다 외주면에 격자상의 구획벽(5)과 배양실(6)이 형성된 원통형의 접촉재(4)를 일정간격이 유지되게 끼우되 핀축(3)의 일단이 오,폐수의 수면위로 노출되게 설치한 것으로서 도면중 미설명부호(7)은 회전체(2)의 양단을 걸어주는 지지구이다.In installing the contact material in the contact oxidation tank 1 in which the air supply pipe 9 is installed at the bottom, the contact oxidation tank 1 is driven so that the rotating body 2 in which several pin shafts 3 are rotated is driven by the motor 8. The cylindrical contact member 4 having a grid-shaped partition wall 5 and a culture chamber 6 formed on the outer circumferential surface of each of the pin shafts 3 of the rotating body 2 is fitted in such a manner as to maintain a constant interval therebetween, One end of the installation is exposed to the water surface of the waste water, as shown in the figure (7) is a support that hangs both ends of the rotating body (2).
이와같이 형성된 본 발명은 스크린조에서 큰덩어리의 협잡물이 걸러진 오,폐수가 혐기성인 부패조, 집수조, 여과석이 설치된 여과조를 차례로 거친 후 접촉산화조(1)로 유입되는 상태에서 지지구(7)에 양단이 걸려있는 원통형의 회전체(2)가 모터(8)로 회동되면 핀축(3)에 끼워져 있는 접촉재(4)들이 핀축(3)에서 회전되면서 회전체(2)를 따라 저회전되어 접촉산화조(1)내에서 공전과 자전을 함께 하게 된다.The present invention formed in this way is filtered through the large tank of filth, the waste water, the waste water, anaerobic decay tank, the collecting tank, the filter tank is installed after passing through the filtration tank in the state of flowing into the contact oxidation tank (1) in the support (7) When the cylindrical rotor 2 having both ends is rotated by the motor 8, the contact members 4 fitted to the pin shaft 3 are rotated on the pin shaft 3 while being rotated low along the rotor 2. In the oxidation tank (1), both revolution and rotation are performed.
상기와같이 공전과 자전을 하는 원통형의 접촉재(4)중 일부가 회전체(2)의 회전에 의해 서서히 오,폐수속에 잠기면 원통형 접촉재(4)의 배양실(6)에는 자연적으로 오,폐수가 유입된다.When a part of the cylindrical contact member 4 which rotates and rotates as described above is gradually immersed in the waste water due to the rotation of the rotating body 2, the culture chamber 6 of the cylindrical contact member 4 naturally contains wastewater and wastewater. Is introduced.
이때 양면이 막혀있는 본 발명의 접촉재(4)는 외주면의 배양실(6)이 깊이가 상당히 깊고 벌집형의 구획벽(5)으로 구획되어 있기 때문에 호기성 미생물의 배양을 위해 에어공급관(9)으로 에어를 분사할 때 접촉산화조(1)내의 오,폐수가 상당히 유동되더라도 오,폐수가 일단 접촉재(4)의 벌집형 배양실(6)에 유입된 상태에서는 유동되는 오,폐수의 영향을 받지 않게 된다.In this case, the contact material 4 of the present invention, in which both surfaces are blocked, is provided with an air supply pipe 9 for cultivation of aerobic microorganisms because the culture chamber 6 of the outer circumferential surface is partitioned by a deeply deep honeycomb partition wall 5. Even when the wastewater in the contact oxidation tank 1 flows considerably when the air is injected, the wastewater is not affected by the flowable wastewater once it enters the honeycomb culture chamber 6 of the contact material 4. Will not.
이에따라 본 발명은 접촉재(4)의 배양실(6)에 유입된 오,폐수의 호기성 미생물이 접촉재(4)의 배양실(6) 주벽에 매우 효과적으로 달라붙게 되는 효과가 있다.Accordingly, the present invention has an effect that the aerobic microorganisms of the wastewater and wastewater introduced into the culture chamber 6 of the contact material 4 adhere to the circumferential wall 6 of the contact material 4 very effectively.
특히 이와같이 오,폐수속에 잠겨서 배양실(6)으로 오,폐수가 유입된 접촉재(4)들은 회전체(2)가 계속 회전됨에 따라 오,폐수의 폭기조 깊이의 약 1/3 정도 수면위로 갔다가 다시 오,폐수속으로 들어가게 되는데, 이때 배양실(6)에 유입된 오,폐수가 아래로 떨어지면서 오,폐수의 표면에 기포를 만들어 주므로 오,폐수속에 공기의 공급이 더욱 원활히 되는 것이다.In particular, the contact materials (4) into which the wastewater flows into the culture chamber (6) after being immersed in the wastewater and wastewater flow to the water surface about 1/3 of the depth of the aeration tank of the wastewater as the rotating body (2) continues to rotate. The wastewater flows into the wastewater. At this time, the wastewater introduced into the culture chamber 6 falls down and creates bubbles on the surface of the wastewater, so that the air is more smoothly supplied to the wastewater wastewater.
그리고 본 발명은 상기와같이 접촉재(4)의 배양실(6)에 호기성 미생물이 견고하게 달라붙은 상태에서 핀축(3)에 축설된 접촉재(4)가 회전체(2)의 회전에 의해 오,폐수의 수면위로 올라갔다가 다시 오,폐수속으로 들어갈때까지 자연적으로 대기와 접촉하게 되므로 호기성 미생물이 대기중의 산소공급을 받게되어 배양이 상당히 촉진되는 효과가 있다.In the present invention, in the state in which aerobic microorganisms firmly adhere to the culture chamber 6 of the contact material 4 as described above, the contact material 4 formed on the pin shaft 3 is turned off by the rotation of the rotor 2. As you go up the surface of the wastewater and then back into the wastewater, you will naturally come into contact with the atmosphere, so that the aerobic microorganisms receive oxygen from the atmosphere, which greatly promotes culture.
이와같이 본 발명은 회전체(2)의 핀축(3)에 축설된 접촉재(4)들이 회전체의 회전을 따라 서서히 회전될 때 오,폐수속에서는 에어공급관(9)으로 주입되는 공기를 공급받고, 오,폐수의 수면위로 올라갈 때에는 대기중의 산소를 공급받으면서도 접촉재(4)의 배양실(6)로 유입되었던 오,폐수가 오,폐수의 수면위로 떨어지면서 수많은 기포를 발생시킴에 따라 호기성 미생물이 산소의 공급을 보다 원활히 받게되는 것으로서, 이러한 본 발명은 접촉재통을 오,폐수속에 완전히 침강시킨 상태로 설치하는 종래의 장치에 비해 미생물의 배양속도가 상당히 촉진되어 많은량의 미생물이 빠른시간내에 배양되므로 오,폐수의 정화효율을 최대한 높혀주는 효과가 있다.As described above, the present invention is supplied with the air injected into the air supply pipe 9 at the wastewater flow rate when the contact members 4 formed on the pin shaft 3 of the rotating body 2 are slowly rotated along the rotation of the rotating body. When rising above the surface of the wastewater, the aerobic microorganism generates a lot of bubbles as the wastewater, which has been supplied to the culture chamber 6 of the contact material 4 while receiving oxygen in the air, drops to the surface of the wastewater and generates numerous bubbles. As the present invention more smoothly receives the supply of oxygen, the present invention significantly promotes the growth rate of microorganisms compared to the conventional apparatus in which the contact container is completely settled in the wastewater and wastewater, so that a large amount of microorganisms are cultured in a short time. Therefore, there is an effect to increase the purification efficiency of the waste water, as possible.
