Description

슬러지 전기 침투탈수 후 교반소멸장치{sludge annihilating apparatus using Microorganism and dehydrator}[0001] The present invention relates to a sludge annihilation apparatus using microorganism and dehydrator,

본 발명은 슬러지 전기 침투탈수 후 교반소멸장치에 관한 것으로, 더 상세하게는 슬러지를 전기침투탈수 후 미생물을 이용하여 감량시킬 수 있는 슬러지 전기 침투탈수 후 교반소멸장치에 관한 것이다. The present invention relates to a sludge electro-osmotic dehydration-agitation extinction device, and more particularly, to a sludge electro-osmosis dehydration-agitation extinction device capable of reducing sludge using microorganisms after electro-osmosis dehydration.

통상적으로 폐수 및 하수처리장에서 발생하는 슬러지(오니)들은 물의 정화를 위해 고분자응집제를 사용하게 되는데, 상기 고분자 응집제에 의해 응집된 상태의 슬러지는 여간해서는 탈수시키기가 곤란하다. 슬러지의 탈수율에 따라 슬러지의 폐기비용 및 재활용 범위 등에 있어서 큰 차이를 발생하게 되고, 또한 슬러지가 갖는 함수율을 현저하게만 줄일 수 있다면 폐기비용이 절감될 뿐만 아니라, 오히려 슬러지의 고형성분들을 연료로도 재활용할 수 있게 되는 등 매우 경제적인 부가가치를 갖게 되는 것이다. Generally, sludge (sludge) generated in wastewater and sewage treatment plants uses a polymer flocculant to purify water, and it is difficult to dehydrate the sludge in a state of flocculation by the polymer flocculant. If the water content of the sludge can be significantly reduced, the disposal cost can be reduced. In addition, it is possible to reduce the disposal cost of the sludge and the recycle range of the sludge, It can be recycled as well.

그러나 종래의 일반적인 단순압착식 탈수장치로는 폐수 슬러지의 탈수는 한계가 있는 것이고 비경제적인 폐단을 갖는 것이어서 최근에는 탈수효율이 더 나은 전기침투 슬러지 탈수장치를 슬러지의 탈수에 활용하고 있는 실정이다.However, in the conventional simple squeeze type dewatering apparatus, the dewatering of the wastewater sludge is limited and the dewatering of the sludge is ineffective.

그러나 전기침투 슬러지 탈수장치는 단수히 슬러지의 슬러지의 수분함량을 줄일 수 있는 것으로, 슬러지의 일부감량을 기대할 수 있으며, 소멸 또는 획기적인 감량을 기대하기는 어렵다. However, the electroosmotic sludge dewatering device can reduce the moisture content of the sludge of the sludge in a short time, and it is expected that a part of the sludge can be reduced, and it is difficult to expect the disappearance or the epochal loss.

대한민국 공개특허 제 2012-002768호에는 음식물 쓰레기의 건조 및 감량 처리장치가 게시되어 있는데, 이 경우 감량을 위한 쓰레기의 탈수를 별도로 수행하여야 하는 문제점이 있다. Korean Unexamined Patent Publication No. 2002-002768 discloses an apparatus for drying and reducing food waste, and in this case, there is a problem that dehydration of waste for reducing the amount of waste must be separately performed.

본 발명의 해결하고자 하는 기술과제는 하수, 축산, 폐수슬러지의 탈수효을 향상시킬 있으며, 탈수된 슬러지를 감량 및 탈수시킬 수 있는 슬러지 전기 침투탈수 후 교반소멸장치를 제공함에 있다. The present invention provides a sludge electro-osmosis dewatering and agitation extinction device capable of reducing dehydration of dehydrated sludge and improving dehydration efficiency of sewage, livestock and wastewater sludge.

상기 기술적 과제를 해결하기 위한 본 발명의 슬러지 전기 침투탈수 후 교반소멸장치는 회전드럼과 상기 회전드럼에 슬러지의 통로가 되는 공간을 구비한 상태로 감싸지는 압착벨트와 상기 회전드럼과 압착벨트에 삼상교류의 각 상별로 정류된 직류전압을 공급함으로써 슬러지에 함유된 수분을 탈수하기 위한 전기침투탈수식 슬러지 전기침투탈수유닛과, According to an aspect of the present invention, there is provided a sludge electro-osmosis dewatering agitation and extinction device comprising a rotating drum and a rotary drum, a squeeze belt wound around the rotating drum with a space serving as a passage for sludge, An electro-osmotic dehydrating sludge electro-osmotic dehydrating unit for dehydrating water contained in the sludge by supplying a rectified DC voltage to each phase of the AC,

본 발명에 따른 슬러지 전기 침투탈수 후 교반소멸장치(10)은 회전드럼(21)과 상기 회전드럼(21)에 슬러지의 통로가 되는 공간을 구비한 상태로 감싸지는 압착벨트(22)와 상기 회전드럼(21)과 압착벨트(22)에 삼상교류의 각 상별로 정류된 직류전압을 공급함으로써 슬러지에 함유된 수분을 탈수하기 위한 전기침투탈수식 슬러지 전기침투탈수유닛(20)과, 상기 전기침투탈수유닛(20)에 의해 탈수된 슬러지를 미생물에 의해 분해하여 소멸 또는 감량시키는 미생물발효교반유닛(50)을 구비한다. The sludge electro-osmosis dewatered agitation and extinction device 10 according to the present invention comprises a rotating drum 21 and a pressing belt 22 wrapped around the rotating drum 21 with a space serving as a passage for sludge, An electroosmotic dewatering sludge electro-osmotic dehydrating unit 20 for dehydrating water contained in the sludge by supplying a direct-current voltage rectified by each phase of three-phase alternating current to the drum 21 and the pressing belt 22, And a microbial fermentation stirring unit (50) for decomposing the sludge dewatered by the dewatering unit (20) by the microorganisms and destroying or reducing the sludge.

상기 전기침투탈수유닛(20)은 상술한 실시예에 의해 한정되지 않고 드럼과압착벨트에 각각 소정의 전압을 인가하여 슬러지를 압착하면서 탈수할 수는 구조이면 가능하다. 이 전기팀투탈수유닛(20)에 의해 탈수되는 슬러지에 포함된 미생물의 세포가 파괴되어 탈수 효율을 높일 수 있다. The electroosmotic dewatering unit 20 is not limited to the above-described embodiments, and may be a structure capable of dewatering while squeezing the sludge by applying a predetermined voltage to each of the drum and the pressing belt. The cells of the microorganisms contained in the sludge dehydrated by the electrical team through dewatering unit 20 are destroyed and the dehydration efficiency can be increased.

그리고 상기 전기침투탈수유닛(20)의 프레임에는 도 1 내지 3에 도시된 바와 같이 미생물 발효교반유닛(50)이 설치될 수 있다.The microbial fermentation stirring unit 50 may be installed in the frame of the electroosmotic dewatering unit 20, as shown in FIGS.

그러나 이에 한정되지 않고, 전기침투탈수유닛(20)과 미생물발효교반유닛(50)의 사이에 탈수된 슬러지를 운반하기 위한 별도의 컨베이어가 설치될 수 있으며, 탈수된 슬러지를 저장할 수 있는 저장탱크가 설치될 수 있다.However, the present invention is not limited thereto. A separate conveyor for conveying dehydrated sludge may be installed between the electroosmotic dewatering unit 20 and the microbial fermentation stirring unit 50, and a storage tank capable of storing dehydrated sludge Can be installed.

상기 탈수된 슬러지가 저장탱크에 저장된 경우, 저장탱크로부터 미생물 발효교반유닛(50)으로 슬러지를 운반하기 위한 슬러지가 설치될 수 있다. When the dehydrated sludge is stored in the storage tank, sludge for transporting the sludge from the storage tank to the microbial fermentation stirring unit 50 may be installed.

한편, 상기 미생물발효교반유닛(50)은 발효탱크(51)의 내부에 별도의 교반유닛(60)이 설치되어 지속적으로 교반시킬 수 있는 구조를 가진다. 상기 교반유닛은 발효탱크(51)의 내부에 원통형의 가이드부(61)가 설치되고 이의 내부에 모터에 의해 교반되는 스크류가 설치될 수 있다. 그리고 상기 교반유닛은 복수개가 수직으로 설치되어 이루어질 수 있으며, 교반유닛은 이중나선의 스크류가 병렬로 설치되어 이루어질 수도 있다. Meanwhile, the microbial fermentation stirring unit 50 has a structure in which a separate stirring unit 60 is installed in the fermentation tank 51 and can be continuously stirred. In the stirring unit, a cylindrical guide portion 61 is provided in the fermentation tank 51, and a screw, which is stirred by a motor, may be installed in the fermentation tank 51. In addition, a plurality of the agitation units may be vertically installed, and the agitation unit may be constructed by installing screws of double helix in parallel.

또한 상기 미생물 발효교반유닛(50)은 도 0에 도시된 바와 같이 내부에 가이드 깃이 형성된 교반드럼이 회전되면서 미생물과 교반시킬 수 있는 구조를 가진다.  As shown in FIG. 1, the microbial fermentation stirring unit 50 has a structure in which a stirring drum having a guide collar formed therein is rotated and stirred with microorganisms.

상술한 바와 같은 미생물 발효교반유닛(50)들은 미생물의 활성화를 위하여 발효 또는 소멸중인 슬러지를 가열하기 위한 가열수단이 더 구비될 수 있다. The microbial fermentation stirring unit 50 may further include heating means for heating the sludge during fermentation or extinction in order to activate microorganisms.

상술한 바와 같이 구성된 본 발명에 따른 슬러지 전기 침투탈수 후 교반소멸장치는 전기침투탈수기에 의해 슬러지가 탈수되는 과정에서 슬러지에 상대적으로 높은 전압이 인가되게 되므로 슬러지에 포함된 미생물의 세포가 파괴되어 탈수효율을 상대적으로 높일 수 있으며, 특히 슬러지에 포함된 응집제가 제거될 수 있으므다. The sludge electro-osmosis dewatering and agitation extinction device according to the present invention configured as described above allows a relatively high voltage to be applied to the sludge during dehydration of the sludge by the electro-osmotic dehydrator, so that the cells of the microorganisms contained in the sludge are destroyed, The efficiency can be relatively increased, and in particular, the flocculant contained in the sludge can be removed.

이와 같이 탈수된 슬러지는 미생물 발효교반유닛(50)에 의해 미생물과 혼합 및 발효됨으로써 소멸 및 감량된다. The sludge thus dehydrated is mixed with the microorganisms and fermented by the microbial fermentation stirring unit 50, thereby being eliminated and reduced.

본 발명은 도면에 도시된 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 본 기술 분야의 통상의 지식을 가진 사람이라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 기술적 보호 범위는 첨부된 등록 청구 범위의 기술적 사상에 의해 정해져야 할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
