본 발명과 관련된 종래의 기술은 대한민국 특허 제10-0876323호(2008. 12. 31. 공고)에 개시되어 있는 것이다. 도 1은 상기 종래의 활성화장치를 이용한 오폐수 및 하수의 고도처리 장치 구성도이다. 상기도 1에서 종래의 활성화장치를 이용한 오폐수 및 하수의 고도처리 장치는 유입된 원수의 농도를 균등하게 유지시키기 위한 산기관(14)과 후처리 공정으로 이송시키기 위한 이송펌프(16) 및 유입되는 원수의 양을 감지하여 상기한 이송펌프(16)의 작동을 조절하기 위한 레벨 스위치(18)가 구비되는 것이다. 또한, 상기 유량조정조(10)를 거친 원수는 이송펌프(16)에 의해 원통형의 미세스크린(15)으로 이송되어 원수중의 고형물질이 제거되고, 이러한 고형물질이 제거된 원수는 무산소조(20)로 이송되는 것이다. 상기 무산소조(20)에서는 유량조정조(10)에서 유입된 처리수의 유기물을 이용하여 침전탈기조(60)로부터 반송되는 슬러지내의 질산성 질소(예, NO3-N)를 무산소 조건에서 환원시킴으로써 질소 기체(N2)를 방출시키는 탈질화반응이 일어나게 되며 이러한 과정을 거쳐 환원된 질소 기체는 최종적으로 대기중으로 방출되어 제거되는 것이다. 이때, 무산소조(20)에는 원수와 침전탈기조(60)로부터 반송되는 슬러지가 가라앉지 않고 이들간의 접촉 기회를 많이 부여함으로써 반응을 극대화하기 위한 교반기(22a)(22b)가 구비되는 것이다. 또한, 무산소조(20)에서 탈질화된 원수는 혐기조(30)로 이송되고 혐기 조건하의 혐기조(<39> 30)에서는 무산소조(20)에서 탈질화된 원수를 혐기성 미생물에 의해 처리하여 고분자물질인 폴리-β-히드록시부티레이트를 오르토포스페이트(o-phosphate)로 방출시킴으로써 인 방출이 유도되는 것이다. 이때에도, 혐기조(30)에는 반응을 극대화할 목적으로 교반기(32)가 구비된다. 또한, 혐기조(30)에서 인 방출이 유도된 원수는 접촉산화조(40)로 이송되고 상기 접촉산화조(40)에는 유입된 원수에 잔류하는 유기물과 암모니아성 질소(NH4+-N)를 미생물에 의해 산화(예, NO3-N)시키기 위해 미생물이 부착된 고정상의 접촉여재(46)가 구비되는 것이다. 이러한 고정상의 접촉여재(46)의 사용에 인해, 혐기조(20)에서 방출되었던 오르토포스페이트를 방출된 양의 약 8배까지 고분자 물질인 폴리-β-히드록시부트레이트로 합성하는 것이다. 또한, 이러한 접촉여재의 사용에 의해, 이 반응조(40)로 유입되는 원수와 미생물의 접촉시간이 증가되고 이로 인해 반응조(40)의 크기 또한 감소되어 전체 반응조의 크기를 감소시키는 효과를 가져오는 것이다. 한편, 이 접촉산화조(40)에는 상기 한 접촉여재 외에도 폭기장치인 산기관(44)이 구비되고 상기 접촉산화조(40)에서 처리된 원수는 막분리조(50)로 이송되는 것이다. 이 막분리조(50)에서는 상기한 접촉산화조(40)와 거의 동일한 기능을 수행하게 되며, 반응조(50)내의 분리막, 특히 침지형 막(56)을 이용하여 슬러지 함유 고형 물질과 처리수로 고액분리하게 되는데, 이때 상기한 분리막의 공극이 대장균의 크기 보다 작으므로 부유물질 및 대장균이 여과되는 것이다. 또한, 분리막, 특히 침지형 막(56)은 막의 폐색을 유발시키는 막면오염(fouling)이 발생하는 경우에 별도의 세정조(90)에서 세정되고 또한 활성화장치(100)를 구비하여 생물반응조내의 MLSS농도를 설계치 정도로 높게 유지함으로써 설계수질과는 상이한 저농도 내지는 고농도의 원수가 유입되거나 유량변동이 있는 경우에도 안정되게 대처할 수 있는 것이다. 이 활성화장치(100)는 내부의 에어레이타(111)에 의해 공기가 공급되며 반송되는 슬러지를 장치내에서 일정시간 활성화시켜 막분리조(50)로 보내게 되는 것이다. 또한, 상기 막분리조(50)에는 상기한 구성이외에도 침전탈기조(60)와 유체연통하는 슬리브관(61)이 하부에 구비되고 고액분리된 처리수는 레벨 스위치(57)의 작동으로 흡인펌프(58)에 의한 펌핑에 의해 유량계(59)를 거쳐 처리수조(70)로 이송되어 방류되고 슬러지는 침전탈기조(60)로 슬리브관(61)을 통해 이송되며. 잉여분의 일부 슬러지는 슬러지 저류조(80)로 이송되어 처리되는 것이다. 이후, 슬리브관(61)을 통해 침전탈기조(60)로 유입된 슬러지는 여기에서 용존산소 제거 과정을 거치면서 재차 고액분리되고 고액분리된 슬러지는 반송펌프(62)에 의한 펌핑에 의해 슬러지 반송라인(66)을 거쳐 무산소조(20)로 반송되는 것이다. 또한 슬러지를 활성화장치(100)에 유입시켜 내부에서 일정시간 미생물의 활성화단계를 거친 후 활성화된 슬러지를 생물반응조에 투입하여 생물반응조의 MLSS농도를 설계치 정도의 높은 농도로 일정하게 유지함으로써 유량과 수질의 변화의 폭이 큰 원수가 유입되는 경우에도 완충작용에 의해 안정되게 대처할 수 있는 고도처리 장치를 제공할 수 있다는 장점을 가지는 것이다.
A conventional technique related to the present invention is disclosed in Korean Patent No. 10-0876323 (published on Dec. 31, 2008). 1 is a block diagram of an apparatus for advanced treatment of wastewater and sewage using the above-described conventional activation device. 1, an apparatus for advanced treatment of wastewater and sewage using a conventional activation apparatus includes an air diffuser 14 for maintaining the concentration of raw water uniformly, a transfer pump 16 for transferring the raw water to a post-treatment process, And a level switch 18 for detecting the amount of raw water and controlling the operation of the feed pump 16 is provided. The raw water having passed through the flow rate adjusting tank 10 is transferred to the cylindrical fine screen 15 by the transfer pump 16 to remove solid matter in the raw water and the raw water from which the solid matter is removed is returned to the anoxic tank 20, . In the anoxic tank 20, the nitrate nitrogen (for example, NO3-N) in the sludge conveyed from the precipitation and degassing vessel 60 is reduced under anaerobic conditions using the organic matter of the treated water flowing in the flow rate adjusting tank 10, (N2) is released, and the reduced nitrogen gas is finally released into the atmosphere and removed. At this time, the anoxic tank 20 is provided with stirrers 22a and 22b for maximizing the reaction by not allowing the sludge conveyed from the raw water and the settling and degassing vessel 60 to sink, but giving much opportunity of contact between them. The raw water denitrified in the anoxic tank 20 is transferred to the anaerobic tank 30 and the raw water denitrified in the anoxic tank 20 is treated by the anaerobic microorganism in the anaerobic tank 30 under the anaerobic condition, Phosphorous release is induced by releasing? -hydroxybutyrate as o-phosphate. At this time, the anaerobic tank 30 is provided with an agitator 32 for the purpose of maximizing the reaction. The raw water from which the phosphorus emission is induced in the anaerobic tank 30 is transferred to the contact oxidation vessel 40 and the organic matter and ammonia nitrogen (NH4 + -N) remaining in the raw water flowing into the contact oxidation vessel 40 Phase contact material 46 to which microorganisms are attached in order to oxidize (for example, NO3-N). Due to the use of this fixed phase contact material 46, the orthophosphate released from the anaerobic tank 20 is synthesized as poly-beta -hydroxybutrate, which is a polymer material, up to about 8 times the released amount. Further, by using such a contact material, the contact time between the raw water flowing into the reaction tank 40 and the microorganism is increased, thereby reducing the size of the reaction tank 40, thereby reducing the size of the entire reaction tank . The contact oxidation vessel 40 is provided with an aeration unit 44 as an aeration device in addition to the contact media as described above. The raw water treated in the contact oxidation vessel 40 is transferred to the membrane separation tank 50. The membrane separation tank 50 performs almost the same function as the above-described contact oxidation tank 40 and is formed by using a separation membrane in the reaction tank 50, particularly, the submerged membrane 56, At this time, since the pore of the separation membrane is smaller than the size of E. coli, the suspended substances and E. coli are filtered. The separation membrane, particularly the submerged membrane 56, is cleaned in a separate washing tank 90 when the fouling of the membrane surface causing the occlusion of the membrane occurs, and also the MLSS concentration in the bioreactor The design water quality can be stably coped with when the raw water of a low concentration or a high concentration different from the design quality is introduced or the flow rate fluctuates. In the activation device 100, air is supplied by the air lattice 111 therein, and the sludge to be transported is activated for a certain period of time in the apparatus and sent to the membrane separation tank 50. The membrane separation tank 50 is provided with a sleeve pipe 61 in the lower portion in fluid communication with the sedimentation and degassing vessel 60 and the solid-liquid separated treatment water is supplied to the suction pump Is pumped by the pump 58 to the treatment water tank 70 via the flow meter 59 and discharged, and the sludge is conveyed through the sleeve pipe 61 to the settling and degassing tank 60. Some of the surplus sludge is transferred to the sludge storage tank 80 and processed. Thereafter, the sludge introduced into the sedimentation and degassing vessel 60 through the sleeve pipe 61 is subjected to solid-liquid separation again through the dissolved oxygen removal process, and the sludge separated by solid-liquid separation is pumped by the return pump 62, Line 66 to the anoxic tank 20. In addition, the sludge is introduced into the activating device 100 to activate the microorganisms for a certain period of time, and then the activated sludge is introduced into the bioreactor to maintain the MLSS concentration of the bioreactor at a high concentration, It is possible to provide an advanced treatment apparatus capable of stably coping with a buffer effect even when raw water having a large variation width is introduced.
