본 발명은 혐기성 생물을 이용한 오수처리에 있어서의 발효조(소화조)에 관한 것이다.The present invention relates to a fermentation tank (digestion tank) in sewage treatment using anaerobic organisms.

종래, 혐기성 생물을 이용하는 오수처리 방법에 있어서의 발효조로서, 혐기성 생물인 균체를 보유하는 담체 또는 충전재를 고정하여, 오수를 순환시키는 고정 상방식과, 담체를 입상(粒狀)으로 하여, 오수와 함께 순환시키는 유동 상방식이 채용되고 있다.Conventionally, as a fermentation tank in a sewage treatment method using anaerobic organisms, a fixed bed system for circulating sewage by fixing a carrier or filler containing cells which are anaerobic organisms, and the carrier as a granule, The fluidized bed system which circulates together is adopted.

상기한 고정상 방식에서는 균체를 보유하는 판 표면에 100μ 이하의 극히 얇은 막상으로 하여 보유되어 있으며, 그 접착력 또는 점착력은 약하므로, 순환하는 오수에 씻겨 흘러서 처리 수축으로 반출되어, 발효조내의 균체량(오니량)이 감소하며, 이 균체량의 감소는 발효 효과를 현저하게 저하시킨다. 그러므로 균체의 보급이 필요하게 된다.In the fixed bed method described above, an extremely thin film of 100 μm or less is retained on the surface of the plate holding the cells, and the adhesion or adhesion thereof is weak. ), And the decrease in cell mass significantly lowers the fermentation effect. Therefore, it is necessary to spread the cells.

또 유동 상방식에서는, 담체가 오수와 함께 회전하므로, 침강, 폐색을 일으키기 쉬우며, 이를 방지하기 위하여 어느 정도의 유속을 필요로 하며, 운전 동력도 필연적으로 커지므로, 관리가 번잡한 등의 문제가 있다.In addition, in the fluidized bed system, since the carrier rotates with the sewage, it is easy to cause sedimentation and blockage, and a certain flow rate is required to prevent this, and the driving power is inevitably increased, which makes management complicated. There is.

이 발명에서는 홈상의 요철을 갖는 회전판으로한 점, 이 요철 회전판을 완속 회전시키는 점 그리고 요철 회전판을 복수개로 분할하여, 분할편 상호간에 단차 또는 결원부의 어느 하나 또는 양쪽을 같이 형성함으로써 상기 문제점을 해결한 것이다.The present invention solves the above-mentioned problem by forming one or both of the steps or the vacancy between the divided pieces by dividing the point into a rotating plate having groove-shaped unevenness, the point of slowly rotating the unevenness rotating plate, and the uneven rotating plate into a plurality of pieces. It is.

다음에 이 발명을 실시예에 의하여 구체적으로 설명한다.Next, this invention is demonstrated concretely by an Example.

이 발명은 제 1 도에 나타낸 바와같이 밀폐뚜껑(2)을 갖는 발효조(1)에 형성한 종축(3)에 장착하는 복수매의 회전원판(A)에 관한 것으로서, 조(1)에는 공지와 같이 조저부에 개구하는 오수 유입관(4)과, 조 상방으로 부터 처리수를 배출시키는 유출관(5)이 형성되어 있다.The present invention relates to a plurality of rotary disks (A) mounted on the longitudinal axis (3) formed in the fermentation tank (1) having a closed lid (2), the tank (1) Similarly, a sewage inflow pipe 4 opening in the bottom of the tank and an outflow pipe 5 for discharging the treated water from above the tank are formed.

회전원판(A)은 제 2 도에 나타낸 바와 같이 혐기성 생물을 함유하는 오니의 담체로서, 방사상 방향, 기타 임의의 형상의 요철면(6)을 형성한 요철 회전판으로 하여, 종축(3)에 적당한 간격을 두고 적의 수 고정하고, 이를 완만한 속도, 예를들면 2~3m/min로 회전시킨다.The rotating disc A is a carrier of sludge containing anaerobic organisms as shown in FIG. 2, and is a concave-convex rotating plate in which the concave-convex surface 6 of the radial direction and other arbitrary shapes is formed, and is suitable for the longitudinal axis 3. Fix the number of enemies at intervals and rotate it at a gentle speed, for example 2 to 3 m / min.

이와같이 함으로써 균을 보유하는 오니는 요철 회전판의 요소에 고이며, 실선의 화살표로 나타낸 완만한 회전속도와, 점선의 화살표로 나타낸 오수의 유동속도와의 상대속도에 의하여 오수에 접촉하여, 소화(消化)작용이 행해지며, 균체를 보유하는 오니와, 그 담체인 요철 회전판과의 접착력이 약해도 오니는 요(凹) 소에서 전동할 뿐, 씻겨 흐름에 의한 균체량의 감소는 없으며, 요철 회전판은 수평 방향으로 회전하고 있으므로, 유입관(4)로 부터 유출관(5)로 향하는 오수의 단락류도 없어져서, 오수의 소화는 효율적으로 행해진다.In this way, the sludge holding the bacteria is accumulated on the elements of the uneven rotating plate, and the sludge is brought into contact with the sewage by the relative speed between the gentle rotational speed indicated by the solid arrow and the flow rate of the sewage indicated by the dotted arrow. Action is carried out, and the sludge retaining the cells and the uneven rotating plate, which is its carrier, are only driven by the urine, but there is no reduction in the amount of the cells due to the washing flow. Since it rotates in the direction, the short circuit of the wastewater which goes from the inflow pipe 4 to the outflow pipe 5 also disappears, and wastewater digestion is performed efficiently.

상기의 요철 회전판은 제 3 도, 제 4 도에 나타낸 바와 같이 복수개로 분할하여, 그 분할편 (a)(b)(c)…을 각각 단차(I)를 형성하여 수평상으로 장착한다.The uneven rotating plate is divided into a plurality of pieces as shown in FIG. 3 and FIG. 4, and the divided pieces (a) (b) (c)... Are formed horizontally by forming a step (I) respectively.

제 5 도는 단차를 형성하는 다른 실시예로서, 각 분할편 (a)(b)(c)…의 일측을 사방으로 절곡면(8)에 의하여 인접하는 분할편과의 사이에 단차(I)를 형성한다.5 is another embodiment for forming a step, wherein each divided piece (a) (b) (c)... A step I is formed between the divided pieces adjacent to each other by the bent surface 8 on one side of the side.

이상과 같이하여 단차를 형성하면 오수의 교반 효과는 더욱 양호하게 되며, 균체와의 접촉을 양호하게 하여 오수의 소화를 촉진함과 동시에, 발생 가스의 부상 분리도 용이하게 된다.When the step is formed as described above, the agitation effect of the sewage is further improved, and the contact with the cells is improved to facilitate the digestion of the sewage, and the floating separation of the generated gas is also facilitated.

또 제 6 도에 나타낸 바와같이, 분할편 (a)(b)(c)… 상호간에 결원부(9)를 형성하면, 발생 가스가 많을 경우에도 부상 분리를 용이하게 할 수가 있다.As shown in FIG. 6, the divided pieces (a) (b) (c)... By providing the vacant portions 9 mutually, floating separation can be facilitated even when there are many generated gases.

제 7 도는 다른 실시예를 나타낸 것으로서 요철면(6)을 갖는 선형의 분할편(m)으로된 소경의 회전판(B)과, 그 외주에 요철면(6)을 갖는 복수매의 호상의 분할편(n)으로써된 외주 회전판(C)을 동일한 종축(3)에 장착한 것으로서, 전술의 단차(I) 또는 결원부(9)는 소경 회전판(B) 또는 회주 회전판(C)에 각각 형성할 수 있음과 동시에, 소경 회전판(B)과 외주 회전판(C) 사이에 형성할 수도 있다.7 shows another embodiment, a small-sized rotating plate B made of a linear split piece m having an uneven surface 6, and a plurality of arc-shaped split pieces having an uneven surface 6 on the outer circumference thereof. The outer circumferential rotating plate C as (n) is mounted on the same longitudinal axis 3, and the step I or the vacant portion 9 described above can be formed on the small-diameter rotating plate B or the circumferential rotating plate C, respectively. At the same time, it can also be formed between the small-diameter rotating plate (B) and the outer circumferential rotating plate (C).

이 발명은 상기와 같은 구성으로써 되며, 중합한 요철 회전판은 서로 다른 수평면을 궤적으로 하여 회전하며, 오수를 균일하게 교반 혼합하며, 균체는 요철 회전판에 의하여 확실하게 보유되어 오수와 접촉하여, 오수를 효율적으로 소화하며, 발생가스도 회전판의 단차, 결원부 등에 의하여 신속히 분리할 수가 있다. 또 요철 회전판은 이를 분할 형성함으로써 단차, 결원부가 용이하게 형성되며, 일체의 원판에 비하여 제작이 용이함과 동시에 종축에 의한 완속 회전이므로, 축의 절곡응력은 작으며, 비교적 가는 종축으로써 족하며, 제작이 용이함과 동시에, 근소한 동력비로 운전관리도 용이하게 되어, 종래의 고정 상방식과 유동 상방식의 결점을 완전히 해소할 수가 있다.The present invention has the configuration as described above, and the polymerized concave-convex rotating plate rotates with different horizontal planes as a locus, and stirs and mixes sewage uniformly. Efficiently extinguish, the generated gas can also be separated quickly by the step of the rotating plate, vacancy. In addition, the uneven rotating plate is formed by dividing it, so that step and vacancy are easily formed, and it is easy to manufacture and slow rotation by the longitudinal axis as compared to the integral disc, so the bending stress of the axis is small, and it is satisfied with the relatively thin longitudinal axis. Simultaneously, operation management is also easy with a small power ratio, and it is possible to completely eliminate the drawbacks of the conventional fixed bed method and the fluidized bed method.
