본 발명은 고농도 오폐수처리 시스템에 관한 것으로, 특히 가정하수, 공장폐수, 축산폐수등과 같은 오폐수가 전처리조-침사조-유량조정조-오존접촉기-체류조-탈질조-질산화조-침전조-집수조-오존접촉산화장치-소독방류조와 같은 일련의 기기를 차례로 통과하면서 오폐수에 함유된 질소와 인 난분해성 오염물질이 안정적이고 신속하게 제거함과 동시에 오폐수 처리 효율이 극대화될 수 있도록 한 고농도 오폐수처리 시스템에 관한 것이다.The present invention relates to a high concentration wastewater treatment system, in particular, wastewater such as home sewage, factory wastewater, livestock wastewater, etc., pretreatment tank-sedimentation tank-flow adjustment tank-ozone contactor-retention tank-denitrification tank-nitrification tank-sedimentation tank-collection tank- Ozone Contact Oxidizer-A high concentration sewage water treatment system that allows for the rapid and efficient removal of nitrogen and phosphorus degradable contaminants contained in waste water while sequentially passing through a series of devices such as ozone effluent tanks. will be.
현재 산업이 고도화됨에 따라 환경 오염의 심각성은 인간의 생존을 위협할 정도에 이르렀으며, 특히 가정하수, 공장폐수, 축산폐수 등으로 인한 지하수, 하천 및 바닥의 오염은 물론 토양 오염도 날로 심각해져 가고 있어 사회문제화 되고 있으며, 그 문제를 해결하기 위하여 많은 연구개발과 투자가 이루어지고 있는 실정이다.As the current industry is advanced, the severity of environmental pollution has threatened the survival of humans. Especially, soil pollution as well as groundwater, rivers and floors caused by household sewage, factory wastewater, and livestock wastewater are becoming increasingly serious. It is becoming a problem, and much research and development and investment are being made to solve the problem.
상기의 수질 및 토양 오염을 최소화하기 위해서는 근본적으로 오염물질의 배출을 줄이는 것이 바람직하겠지만 사회가 고도와 산업화 되어감에 따라 수질 및 토양에 악영향을 미치는 각종 오염물질의 발생은 불가피하게 되고 그에 따른 오염된 물로부터 오염물질을 즉시 제거하거나 해롭지 않게 처리하는 등의 적절한 오폐수 처리 조치가 필요 불가결하다.In order to minimize the above water and soil pollution, it is desirable to reduce the emission of pollutants, but as the society is advanced and industrialized, the generation of various pollutants that adversely affect the water quality and the soil becomes inevitable and contaminated accordingly Appropriate wastewater treatment measures, such as immediate removal of contaminants from water or harmless disposal, are essential.
상기와 같은 사회 문제화 되고 있는 오폐수를 처리하는 종래 방법은, 폐수 중에 포함된 상대적으로 큰 오염물을 균일한 크기의 구멍이 형성된 스크린으로 걸러내는 스크린공정과 물보다 무거운 오염물을 중력에 의해 분리시키는 침강분리등의 물리적 조작을 적용하여 오폐수 중에 포함된 부유물질과 침전물질을 일차적으로 제거하게 되는 것이며, 이차적으로는 응집제, 흡착제 및 살균제 등의 각종 화학약품을 사용하여 현탁 부유물을 응집 및 침강시키거나 흡착시키고 합성수지 병원균을 사멸시키는 등의 화학적 단위 공정과, 미생물의 작용에 의해 비 침강성 생분해 유기물을 분해하여 기체로 전환시키거나 부유물로 응집시켜 침강제거 하는 등의 생물학적 단위공정을 사용하며, 폐수 중에 포함된 유기물을 주로 제거한다. The conventional method for treating the socially problematic wastewater as described above, the screen process to filter out the relatively large contaminants contained in the wastewater to a screen having a hole of uniform size and sedimentation separation that separates the contaminants heavier than water by gravity It is used to remove suspended substances and sediment contained in waste water by applying physical operation such as the first.Secondary flocculation and sedimentation or adsorption of suspended solids using various chemicals such as flocculant, adsorbent and disinfectant. It uses chemical unit processes, such as killing synthetic resin pathogens, and biological unit processes, such as decomposing non-settling biodegradable organics by the action of microorganisms, converting them into gases, or flocculating them with suspended solids. Mainly remove
이후 일명 고도 처리라고 하는 삼차처리를 하게 되고, 이는 앞서 언급한 일차 및 이차 처리에 언급된 여러 가지 물리적 수단과 단위 공정이 복합적으로 적용되며, 일차 및 이차 처리에서 쉽게 제거되지 않는 암모니아, 질소, 인등을 비롯한 각종 무기물과 중금속 및 합성유기물 등을 제거한다. After that, a third treatment, also known as advanced treatment, is a combination of various physical means and unit processes mentioned in the above-mentioned primary and secondary treatments, and ammonia, nitrogen, phosphorus, etc., which are not easily removed from the primary and secondary treatments. Remove various minerals, including heavy metals and synthetic organics.
그리고 근래에 들어서는 상기의 오폐수처리 방법 중 미생물의 작용에 의해 오폐수를 처리하는 방법이 널리 이용되고 있으며, 상기의 미생물을 이용한 오폐수 처리 방법도 부유상태의 미생물을 이용하는 활성 슬러지 공법 보다는 일정형태의 담체을 구비하고 이 담체상에 미생물을 배양시켜 각종 오염물질을 제거하는 방식이 하기에 설명될 장점으로 인해 널리 이용되고 있다. In recent years, a method of treating wastewater by the action of microorganisms among the wastewater treatment methods has been widely used, and the wastewater treatment method using the microorganisms has a carrier having a certain form rather than an activated sludge process using suspended microorganisms. And a method of culturing microorganisms on this carrier to remove various contaminants is widely used due to the advantages described below.
상기의 표준활성과 미생물 담체를 이용한 처리 방식은 오페수가 표준활성을 통하여 고농도의 오염물이 1차 제거되고 2차로 복합담체를 통과하면 미생물과 유기물이 상기 담체에 접촉되어 미생물은 더욱 증식되고 그리하여 오폐수 내 유기물이 제거되는 방식으로서, 미생물이 담체에 부착되어 생물막을 형성함으로 증식속도가 느린 미생물도 외부로 유출되지 않고 증식할 수 있어 외부로의 유출슬러지 발생량이 적고 미생물이 다양하게 출현하여, pH, 충격부하의 변동에 강하며 난분해성 물질의 분해력도 강하고 활성 슬러지 공정과는 달리 슬러지 부상 등의 현상이 없어 운전관리가 용이한 장점이 있었으며 목적에 따라 특정미생물을 담체에 고착시키거나 담체의 성분을 에너지원으로 공급할 수 있거나 오염물질의 응집을 도울 수 있도록 되어 있었다. In the treatment method using the standard activity and the microbial carrier, when the operably water is first removed through the standard activity and the secondary carrier passes through the complex carrier, the microorganism and the organic substance are contacted with the carrier, so that the microorganism is further proliferated and thus in the waste water. As the organic matter is removed, microorganisms are attached to the carrier to form a biofilm, so microorganisms with slow growth rate can proliferate without being leaked to the outside. It is resistant to load fluctuations, has strong decomposability of hardly decomposable materials, and unlike activated sludge process, there is no sludge injuries, which makes it easy to manage and maintain specific microorganisms on the carrier or energy of the carrier. It could be supplied as a source or to help agglomerate contaminants.
상기의 흐름도는 고도처리 시에 탄소원의 부족을 최소화한 공법이며 질산화 및 고도처리 공정중에서 미생물이 서식할 수 있도록 제공되는 여재와 이 여재에 생성되는 미생물막을 포함하는 미생물 담체는 가장 중요한 역할을 수행하는 것으로서, 이런 미생물 담체는 원형등과 같이 일정형상을 이루면서 접촉 폭기조 내의 유로를 고르게 할 수 있는 규칙적인 배열을 갖고 채워지게 된다. The above flow chart is a method of minimizing the lack of a carbon source during the advanced treatment, and the microorganism carrier including the media provided to allow the microorganism to inhabit during the nitrification and the advanced treatment process and the microbial membrane generated in the media play the most important role. As such, such a microbial carrier is filled with a regular arrangement to even out the flow path in the contact aeration tank while forming a certain shape such as a circle or the like.
이러한 종래의 미생물 담체는 이제까지 천연암석이나 인조 플라스틱형태의 여재가 제공되어 왔으며, 이로 인해 표면적이 적게 됨은 물론 표면 공극이 없게 되는 미생물 담체가 구성되는 것일 뿐 만 아니라 미생물과의 친화력이 작아 부착된 미생물이 이탈되는 탈리현상이 쉽게 일어나는 문제점이 발생 되었으며, 이렇게 여재상에서 쉽게 미생물이 박리되어 탈리됨으로 인해 미생물 배양에는 그 만큼 많은 시간이 소요되는 문제점이 있었고, 또한 완전한 미생물 담체를 이루는 데도 많은 시간이 소요됨은 물론 배양된 미생물의 탈리로 인하여 양호한 오폐수처리를 기대할 수 없는 것일 뿐만 아니라 질소와 인제거를 위한 고도처리에 문제점이 있었으며 미생물의 부착 및 배양이 쉽지 않아 그만큼 오폐수 처리효율도 떨어지게 되고 처리된 수질도 악화되기 쉬운 문제점이 있는 등 여러 가지 제반 문제점들이 발생되었다.Such conventional microbial carriers have been provided with media in the form of natural rocks or artificial plastics, and thus, not only the surface area is reduced, but also the microbial carriers having no surface voids are formed, as well as the microorganisms having low affinity with microorganisms are attached. There is a problem that the detached detachment phenomenon easily occurs, and because the microorganism is easily detached and detached from the filter medium, the microbial culture takes much time, and it takes a long time to form a complete microbial carrier. Of course, not only good wastewater treatment could not be expected due to the desorption of cultured microorganisms, but there was also a problem in advanced treatment for nitrogen and phosphorus removal, and it was not easy to attach and cultivate microorganisms, which reduced the wastewater treatment efficiency and deteriorated treated water quality. Become There are various problems, including easy problems.

이와 같이 구성된 본 발명은 일정량의 오폐수가 전처리조(100) 내부로 공급되면 이 전처리조(100)는 오폐수에 함유된 비교적 모래등과 같이 비교적 큰 고형물은 일차적으로 걸러내고 토사등과 같이 비교적 작은 협잡물은 이차적으로 자연 침강시켜 분리하게 된다.In the present invention configured as described above, when a predetermined amount of waste water is supplied into the pretreatment tank 100, the pretreatment tank 100 filters out relatively large solids such as relatively sand contained in the waste water and relatively small contaminants such as earth and sand. Is sedimented by natural sedimentation.
이후 전처리조(100)를 통과한 오폐수가 침사조(100) 상단으로 유입되면 상기한 침사조(200)는 전처리조(100)에서 걸러내지 못한 미세한 토사류나 부유물질을 걸러낸다. Then, when the waste water passing through the pretreatment tank 100 flows into the top of the immersion tank 100, the immersion tank 200 filters out the fine soils or suspended matters that were not filtered out from the pretreatment tank 100.
상기와 같이 전처리조(100), 침사조(200)를 차례로 거친 거친 오폐수가 유량조정조(300)의 하단을 통하여 내부로 유입된 오폐수는 산기관(310)에 의해 부패되는 것이 방지되고, 내부로 유입되는 오폐수 량은 수위계(320)를 통하여 적정량 만큼 유입된다.As described above, the wastewater that has been roughly passed through the pretreatment tank 100 and the sedimentation tank 200 in sequence through the lower end of the flow adjustment tank 300 is prevented from being decayed by the diffuser 310, and then into the inside. The amount of wastewater introduced is introduced by an appropriate amount through the water level gauge 320.
한편, 유량조정조(300)를 거친 오폐수와 오존발생기(410)에서 발생된 오존은 오존접촉기(400)의 오존접촉펌프(420)에 의해 진공 흡입되고, 진공 흡입된 오폐수와 오존은 오존접촉펌프(420) 내부에서 혼합 접촉하면서 1차 오존 처리된다.On the other hand, the ozone generated in the waste water and ozone generator 410 passed through the flow rate adjustment tank 300 is vacuum sucked by the ozone contact pump 420 of the ozone contactor 400, the vacuum sucked waste water and ozone are ozone contact pump ( 420, primary ozone treatment with mixed contact inside.
오존접촉기(400)를 통해 오존처리된 오폐수가 체류조(500) 내부로 유입되면 상기한 체류조(500)는 오폐수 속의 용존오존이 충분히 제거될 수 있도록 오폐수를 일정시간 체류시키기 때문에 산화작용이 극대화되어 오폐수 속에 함유된 오염물질이 그만큼 효과적으로 제거된다.When the ozonated waste water is introduced into the retention tank 500 through the ozone contactor 400, the retention tank 500 retains the waste water for a predetermined time so that the dissolved ozone in the waste water can be sufficiently removed, thereby maximizing oxidation. Thus, the pollutants contained in the waste water are effectively removed.
상기와 같이 체류조(500)를 통과하면서 용존오존이 제거된 오폐수가 탈질조 (510)내부로 유입되면 내부에 형성된 교반기(511)를 이용하여 오폐수를 탈질시키고, 탈질된 오폐수는 질산화조(520)로 보내어진다.When the wastewater from which dissolved ozone is removed while flowing into the denitrification tank 510 is introduced into the denitrification tank 510 as described above, the waste water is denitrated using an agitator 511 formed therein, and the denitrified waste water is nitrification tank 520. Is sent).
이때 질산화조(520)를 통과한 오폐수 일부는 자연유하로 유량조정조(300)에 반송되고, 나머지 일부 오폐수는 침전조(530) 내부로 유입된다. 침전조(530) 내부로 오폐수가 유입되면 오폐수 속에 함유된 잉여오니를 분리하고, 분리된 오니는 오니농축조(800)로 공급하고 잉여오니가 제거된 오폐수는 집수조(540)로 공급된다.At this time, a part of the waste water passing through the nitrification tank 520 is returned to the flow rate adjustment tank 300 as a natural oil, and the remaining part of the waste water is introduced into the settling tank 530. When the wastewater flows into the sedimentation tank 530, the sewage sludge contained in the wastewater is separated, and the separated sludge is supplied to the sludge concentration tank 800, and the wastewater from which the surplus sludge is removed is supplied to the collection tank 540.
집수조(540)를 통과한 오폐수가 오존접촉산화장치(600) 내부로 유입되면 오폐수 속에 함유된 오염물질은 2차로 오존 고도처리된다.When the wastewater that has passed through the sump 540 flows into the ozone contact oxidation apparatus 600, the pollutants contained in the wastewater are subjected to advanced ozone treatment.
이를 더욱 상세하게 설명하면 집수조(540)에 저장된 오폐수와 오존발생기(670)에서 발생된 오존은 오존접촉탱크(610)에 의해 진공 흡입 혼합되고, 혼합된 오폐수와 오존은 압력탱크(620) 내부로 투입되면서 내부 압력에 의해 용존이 최대화 된다.To explain this in more detail, the waste water stored in the water collection tank 540 and ozone generated in the ozone generator 670 are vacuum suction mixed by the ozone contact tank 610, and the mixed waste water and ozone are mixed into the pressure tank 620. Dispensing is maximized by the internal pressure as it is introduced.
압력탱크(620)를 거쳐 용존된 오폐수는 오존접촉산화기(630) 하단으로 압송되고, 압송된 오폐수는 상부로 부상하는 과정에서 오폐수와 오존이 충분히 접촉하게 된다. 이때 미 잔류 오존가스는 배오존분해기(640) 의해 오존접촉산화기(630) 상부에서 포집되어 제거된다.The waste water dissolved through the pressure tank 620 is pumped to the lower portion of the ozone contact oxidizer 630, and the pressurized waste water is sufficiently brought into contact with the waste water in the process of rising to the top. At this time, the residual ozone gas is collected by the ozone decomposer 640 and removed from the upper portion of the ozone contact oxidizer 630.
오존접촉산화기(630)를 통과한 오폐수는 여과기(650)를 거치는 과정에서 오염물질은 걸러지고 정화된 여과수만 여과재(660)로 투입된다. 여과재(660)로 투입된 오폐수는 여과재(660)를 거치는 과정에서 오폐수에 함유된 용존오존 및 용존 오염물질은 여과되고, 정화 처리된 처리수는 소독방류조(700)로 공급된다.The wastewater that has passed through the ozone contact oxidizer 630 is filtered while contaminants are filtered through the filter 650, and only the filtered water is introduced into the filter medium 660. The wastewater introduced into the filter medium 660 is filtered through the filter medium 660, and dissolved ozone and dissolved contaminants contained in the wastewater are filtered, and the treated water is supplied to the disinfection discharge tank 700.
소독방류조(700)로 공급된 처리수는 내부에 형성된 소독기(710)를 통하여 살균 처리되고, 살균 처리하면서 정화된 물은 외부로 방출되는 것이다.The treated water supplied to the disinfection discharge tank 700 is sterilized through the sterilizer 710 formed therein, and the purified water is discharged to the outside while sterilizing.
