Description
본 발명은 하수·오수·폐수에 함유되어 있는 질소성분을 제거하기 위한 탈질조와 반응조 및 침전조 등이 수직 일체형으로 구성된 하나의 처리조에서 생물학적 처리와 함께 침전처리를 동시에 수행할 수 있게 하는 탈질·반응·침전조 수직 일체형 하수·오수·폐수의 생물학적 처리방법 및 장치에 관한 것이다.The present invention is a denitrification tank for removing nitrogen components contained in sewage, sewage, and waste water, and a denitrification / reaction for simultaneously performing a precipitation treatment together with biological treatment in a single treatment tank having a vertically integrated unit. It relates to a method and apparatus for biological treatment of sedimentation tank vertically integrated sewage, sewage, and wastewater.
일반적으로 하수·오수·폐수(이하 유입수라 한다)에 존재하는 오염물질은 물리적, 화학적 또는 생물학적 방법에 의해 처리되고 있다.In general, pollutants present in sewage, sewage and wastewater (hereinafter referred to as influent) are treated by physical, chemical or biological methods.
종래 유입수를 처리하는 방법은 도 3에 도시한 바와같이 유입수에 포함되어 있는 큰 입자의 부유물질을 제거하는 스크린조(100)에서 1차적으로 제거하고, 이어서 유량조정조(101)에서는 오염물질 농도와 유량을 조정한 다음 1차침전조(102)에서 침전을 유도한 후 계속해서 활성오니조(103), 탈질조(104), 2차침전조(105)를 거치게 하는데, 상기한 활성오니조(103)에서는 공기를 폭기시키는 방법으로 미생물 접촉여재에 활성오니라는 미생물덩어리가 접촉되게 하고, 또 상기한 미생물덩어리는 유입수에 함유되어 있는 유기성 오염물질을 영양성분으로 하여 증식하면서 자기소화작용으로 분해되도록 하며, 상기의 탈질조(104)에서는 활성오니조(103)를 거친 유입수에 함유되어 있는 질소성분을 산화질소화시켜 제거하는 것이며, 이후 2차침전조(105)에서 증식된 미생물덩어리는 침전시키고 상등액에 해당되는 처리수는 처리수조(106)에 보내고 2차적으로 침전된 활성오니의 일부는 활성오니조(103)에 반송한다.The conventional method of treating the influent is firstly removed from the screen tank 100 for removing the large particles of suspended solids contained in the influent as shown in FIG. After adjusting the flow rate and then inducing precipitation in the primary sedimentation tank 102, the activated sludge tank 103, the denitrification tank 104, and the secondary sedimentation tank 105 are continuously passed. In a method of aeration of air to the microorganisms contacting the microorganism contact medium, the microbial masses are contacted, and the microbial masses are decomposed by self-extinguishing while proliferating by organic nutrients contained in the influent as nutrients, In the denitrification tank 104, the nitrogen component contained in the influent water passed through the activated sludge tank 103 is removed by nitric oxide, and then the microorganism propagated in the secondary precipitation tank 105 is removed. The mass is precipitated, and the treated water corresponding to the supernatant is sent to the treated water tank 106, and a part of the secondary sludge precipitated is returned to the activated sludge tank 103.
상기와 같이 2차침전조(105)에서 보내진 처리수는 처리수조(106)에서 일시적으로 저장되었다가 소독조(107)에서 최종적으로 소독된 다음 방류시키는 공정으로 되어 있다.As described above, the treated water sent from the secondary sedimentation tank 105 is temporarily stored in the treatment water tank 106 and finally sterilized by the disinfection tank 107 and discharged.

상기 탈질 겸용 반응조(3)의 상,하부에 설치된 반응조(3a)와 탈질조(3b)는 차단판(31)으로 구획되며, 상기 차단판(31)에는 다수개의 스트레이너(32)와 산기관(33)이 마련되어 있는데, 상기한 산기관(33)은 부로워(4)의 에어라인(41)에 연결되어 반응조(3a) 내부에 공기를 공급하므로서 폭기작용을 발생되게 한다.The reaction tank 3a and the denitrification tank 3b installed at the upper and lower portions of the denitrification combined reaction tank 3 are divided by a blocking plate 31, and the blocking plate 31 has a plurality of strainers 32 and an diffuser pipe ( 33), the diffuser 33 is connected to the air line 41 of the blower (4) to supply air into the reaction tank (3a) to generate an aeration action.
또한 상기 탈질조(3b)의 하부에는 유량조정 공정(B)의 유량조정조(5)의 유입수라인(51)이 연결되어 있으며, 상기 유입수라인(51)에는 펌프(52)가 장설되어 유량조정조(5)의 유입수를 펌핑하여 탈질조(3b)로 공급하는데, 상기 유입수라인(51)의 유출단에는 유량조절장치(53)를 장설하여 유입수가 설정된 량으로 유입될 수 있도록 하며, 또 체크밸브(54)를 장설하여 유입수가 역류하는 것을 방지할 수 있도록 한다.In addition, a lower portion of the denitrification tank 3b is connected to an inflow water line 51 of the flow rate adjustment tank 5 of the flow rate adjustment process B, and a pump 52 is installed in the inflow water line 51 so that the flow rate adjustment tank ( 5) to supply the inflow water to the denitrification tank (3b), the outlet of the inlet line 51 is installed a flow control device 53 so that the inflow can be introduced in a set amount, and check valve ( 54) to prevent inflow of backflow.
상기 반응조(3a) 내부에는 단면이 ∧형으로 되고 공극율이 큰 미생물 접촉여재(일명:Super House)(34)가 다수층으로 적층되어 있으며, 내상부에 형성된 정류유로(35)의 상측으로는 안내판(36)을 장설하며, 또 상기 안내판(36)의 상부에는 유동공(37)을 다수 천공하여 반응조(3a)의 상부수면이 이동할 수 있도록 한다.Inside the reactor 3a, a microorganism contact medium (aka: Super House) 34 having a cross-sectional shape and a large porosity is stacked in multiple layers, and a guide plate is located above the rectifying passage 35 formed in the upper portion. (36) is installed, and the upper portion of the guide plate 36 to perforate a plurality of flow holes 37 to allow the upper surface of the reaction tank (3a) to move.
상기 반응조(3a)의 외상부에 형성된 1차집수유로(38)는 상기 정류유로(35)에서 월류하는 1차처리수를 집수하여 유하라인(39)을 통해 탈질조(3b) 외주를 통해 침전조(2)로 유하시키도록 구성되어 있다.The primary collecting channel 38 formed on the outer portion of the reactor 3a collects the primary treated water flowing from the rectifying channel 35 and setstles through the outer periphery of the denitrification tank 3b through the Uharain 39. It is comprised so that it may flow to (2).
한편, 상기 침전조(2)의 하부에는 침전된 활성오니를 반송시킬 수 있는 반송라인(23)이 인입되는데, 상기 반송라인은 유입수라인(51)에 장설된 펌프(52)의 펌핑라인(55)에 연결시킨다.On the other hand, the lower part of the sedimentation tank (2) is introduced into the conveying line 23 for conveying the settled activated sludge, the conveying line is the pumping line 55 of the pump 52 installed in the inlet line 51 To.
이와같은 구성된 본 발명의 작용을 설명한다.The operation of the present invention thus configured will be described.
상기 스크린 공정(A)을 거친 유입수는 유량조정조(5)에 유입,저장되며 펌프(52)에 의해 펌핑라인(55)으로 펌핑되어 유입수라인(51) 및 정류판(53)을 통해 탈질조(3b)로 유입된다.The inflow water that has passed through the screen process (A) is introduced into and stored in the flow rate adjusting tank 5 and is pumped into the pumping line 55 by the pump 52 to remove the denitrification tank through the inflow line 51 and the rectifying plate 53. 3b).
상기 탈질조(3b)에 들어있는 유입수는 차단판(31)에 형성된 공급통로(32)를 통해서만 반응조(3a)로 유출되므로 탈질조(3b) 하부측에서 유입된 유입수는 무산소상태에서 일정시간 머무른 후 반응조(3a)로 유출되는데, 이때 탈질조(3b) 내부로 유입된 후 무산소 상태에서 유동하면서 지체하는 동안 질소성분이 질소가스가 되어 반응조(3a)를 거쳐 대기로 방출되는 것이다.Since the inflow water in the denitrification tank 3b flows out into the reaction tank 3a only through the supply passage 32 formed in the blocking plate 31, the inflow water introduced from the lower side of the denitrification tank 3b remains in the anaerobic state for a certain time. It is then discharged to the reaction tank (3a), in which the nitrogen component becomes nitrogen gas and is released into the atmosphere through the reaction tank (3a) during the delay while flowing into the denitrification tank (3b) while flowing in an anoxic state.
상기 반응조(3a) 내부는 산기관(33)에서 공급되는 공기에 의하여 폭기작용이 수반되고 있으며, 또 다수층으로 적층된 미생물 접촉여재(34)들에 의하여 유입수에 함유되어 있는 오염물질은 미생물 접촉여재(34)에 접촉함과 동시에 미생물이 증식하면서 자기분해를 일으키게 되므로서 오염물질 제거 및 미생물이 소멸,제거되며, 따라서 반응조(3a)의 상부에는 질소성분과 오염물질이 1차적으로 제거된 1차 처리수가 위치하게 되고, 이 1차 처리수는 정류유로(35)로 유입되면서 1차집수유로(38)로 월류하게 된다.The inside of the reaction tank 3a is accompanied by aeration by air supplied from the diffuser 33, and contaminants contained in the inflow water by the microbial contact media 34 stacked in multiple layers are contacted with microorganisms. At the same time as the contact with the filter medium 34, the microorganisms proliferate to cause self-decomposition, so that the contaminants are removed and the microorganisms are extinguished and removed. Therefore, nitrogen and contaminants are firstly removed at the top of the reaction tank 3a. The primary treated water is located, and the primary treated water flows into the rectifying flow passage 35 and overflows to the primary collecting flow passage 38.
상기 1차집수유로(38)에 월류,집수된 1차 처리수는 유하라인(39)을 따라 흘러내려 침전조(2)의 하부측으로 유하하게 되고, 상기 침전조(2)에서는 반응조(3a)에서 제거되지 않고 1차 처리수와 함께 유입된 미생물덩어리 즉, 활성오니를 침전시킴과 동시 2차 처리수는 2차집수유로(21)에서 집수한 다음 유출라인(22)을 통해 방류공정(D)의 방류수조로 보낸다.The primary treated water collected and collected in the primary collection channel 38 flows down the Uharain 39 to flow down to the lower side of the settling tank 2, and the settling tank 2 is removed from the reactor 3a. Instead of precipitating the microbial mass introduced with the first treated water, that is, the activated sludge, and simultaneously treating the second treated water in the second catchment flow passage 21 and then collecting the discharge through the outlet line 22. Send to discharge tank.
상기에서 침전조(2)에 침전된 활성오니는 반송라인(23)을 통해 펌핑라인(55)으로 반송시키면서 재처리를 반복 되풀이하므로서 미생물의 자기분해를 유도하여 활성오니의 발생율을 줄일 수 있게 된다.The activated sludge settled in the settling tank 2 is carried out to the pumping line 55 through the conveying line 23 to repeat the reprocessing to induce the self-decomposition of the microorganism to reduce the generation rate of the activated sludge.
상기와 같은 본 발명에 의하면 유입수에 함유되어 있는 질소성분 및 오염물질을 실질적으로 제거하는 탈질조와 반응조 그리고 침전조를 수직 일체형의 통합처리 구조물안에 구성하므로서 유입수에 함유되어 있는 질소성분과 오염물질을 생물학적으로 제거처리할 수 있는 효과와 함께 한곳에서 연속적으로 처리하므로서 효율적인 처리효과를 기대할 수 있으며, 또한 탈질조에 유입수를 공급하는 작용만으로 유입수가 반응조와 침전조를 자연적으로 유하하도록 구성되어 있으므로서 유입수의 정화처리에 소요되는 운전비를 절감시킬 수 있음은 물론 상기한 탈질조, 반응조, 침전조가 하나의 통합처리 구조물로 구성되어 있어 관리가 용이하고 무인운전이 가능해져 유지 및 보수관리비용을 절감시킬 수 있으며, 특히 본 발명의 통합처리 구조물은 수직 일체형으로 구성된 것이므로 종래와 같이 반응조, 탈질조, 침전조를 개별적으로 설치하는 것에 비하여 설치면적을 줄일 수 있는 이점이 있어 부지선정 및 부지매입 등이 용이함과 동시 그에 소요되는 경비를 현저하게 절감시킬 수 있는 효과가 있을 뿐 아니라 건설비도 줄일 수 있는 등 매우 경제적인 효과가 있어 마을단위나 아파트단위 또는 공장단위로 설치하여 환경오염문제를 해결할 수 있는 유용한 발명인 것이다.According to the present invention as described above, the denitrification tank, the reaction tank, and the sedimentation tank for substantially removing the nitrogen components and contaminants contained in the influent are constituted in a vertically integrated integrated treatment structure to biologically remove the nitrogen components and contaminants contained in the influent. In addition to the effect that can be removed and treated in one place continuously, you can expect an efficient treatment effect, and also by supplying the influent to the denitrification tank, the influent will naturally flow down the reaction tank and sedimentation tank, In addition to reducing the operating costs required, the denitrification tank, reaction tank, and sedimentation tank are composed of one integrated treatment structure, which enables easy management and unmanned operation, thereby reducing maintenance and maintenance costs. The integrated treatment structure of the invention is vertical As it is composed of a body type, it has the advantage of reducing the installation area compared to installing the reaction tank, denitrification tank, and sedimentation tank separately as in the prior art. It is a useful invention that can solve the environmental pollution problem by installing in a village unit, apartment unit or factory unit because it is not only effective but also can reduce construction cost.
