발포막 접촉식 다단계 오수처리 방법 및 장치 {THE METHOD AND ASPARATUS OF PURIFICATING SEWAGE THROUGH PROCESS OF FOAMING MEMBRANE AND ETC POCESES}Foam membrane contact multistage sewage treatment method and apparatus {THE METHOD AND ASPARATUS OF PURIFICATING SEWAGE THROUGH PROCESS OF FOAMING MEMBRANE AND ETC POCESES}

본 발명은 발포막 접촉식 다단계 오수 정화처리공법에 관한 것으로서 특히 정화장치 내부를 혐기공정, 호기공정, 변형호기공정으로 구분하여 탈인, 탈질기능과 유기물 분해기능 및 최종자기조립 기능으로 구성하여 생물상의 특성별 분별에 대한 우점성 증대로 오수 중의 유기물 외 영양염류 등을 동시 제거하면서 주 오염원인 유기물을 최종단계까지 정화시킬 수 있는 것이다.The present invention relates to a foam membrane contact type multi-stage sewage treatment process. Especially, the inside of the purification apparatus is divided into anaerobic process, aerobic process, and modified aerobic process to be dephosphorized, denitrified, organic matter decomposing, and final self-assembling. By increasing the preponderance of classification by characteristics, organic matter, which is the main pollutant, can be purified to the final stage while simultaneously removing nutrients and other organic substances in sewage.

본 발명은 각종 생활오수나 생물학적계의 정화처리하여 주는 것으로 정화효율 향상 및 영양염류 제거에 기인하면서 단계별 공정에 의한 다단계 분리처리로 처리기능에 특성별 효과에 따른 정화율의 안정화가 유지되는 오수처리방법과 장치에 관한 것이다.The present invention purifies various living sewage or biological systems, resulting in the improvement of purification efficiency and the removal of nutrients, and the sewage treatment which maintains the stabilization of the purification rate according to the effects of characteristics by the multi-stage separation treatment by the stepwise process. It relates to a method and an apparatus.

그러나 지속적인 생활수준 향상 및 생활습성 변화로 오염특성이 다양화되면서 기존의 정화시설은 증가되는 오염부하 및 특성변화에 적응성 부재로 안정적 정화능력이 떨어져 수질오염부하 요인이 증가되는 현상이 일어나고 있다.However, as the pollution characteristics are diversified due to continuous improvement of living standards and changes in lifestyle, existing purification facilities are not able to adapt to increasing pollution loads and characteristic changes, resulting in an increase in water pollution load factors due to lack of stable purification ability.

특히 종래의 정화방식은 처리공정에 단순기능과 단순설비로 유입부하 증감이나 관리소홀 난분해성 물질 유입시 미생물에 의해 완전히 분해되기 전에 방류되어지는 모순과 단일계 처리공정으로 기능에 편차가 심하거나 초기효과에 그쳐 그 기능이 저하되기 일수이며 개발시점의 모형 실험적 결과치에 현실적 적응력이 떨어져 처리효율 개선에 기여치 못하며 고도의 처리기술을 요하는 탈인ㆍ탈질 기능의 효율 및 관리기술에 어려움이 많았다.In particular, the conventional purification method is a contradiction and single treatment process that is discharged before being completely decomposed by microorganisms when the inflow load increases or decreases due to simple functions and simple facilities in the treatment process, or when the inertly decomposed substances are introduced. It was only effective, and the function was deteriorated, and it was difficult to improve the efficiency and management technology of dephosphorization and denitrification, which did not contribute to the improvement of treatment efficiency due to lack of realistic adaptability to the model experimental results at the time of development.

그 대안으로 추가보조처리 시설 및 기능 부가시설이 한층 요구되고 있는 실정이다.As an alternative, additional auxiliary treatment facilities and functional additional facilities are required.

또한 내부 충진 접촉재로 합성수지계나 섬유제는 단순상으로 접촉재의 생물막 기능에 변화가 심하고 단순성 통일 기능으로 생물상의 우점종이 단조로와 처리수 수질에 편차가 많다.In addition, synthetic resins and textiles have a simple change in the biofilm function of the contact material as the internal filling contact material, and biologically dominant species have a large variation in the forging quality and the treated water quality.

그리고 생물상이 편중되는 기능으로 과다한 세균류 번식에 따른 원생, 후생동물의 미활성으로 미생물간의 상호 솎음효과성 특성이 적어 처리수의 투명성(맑음)이 저하되면서 잉여 슬러지 발생량을 저감시키지 못하여 2차 처리비용 부담을가증시키는 요인과 수질오염의 요인이 되어 그에 따른 기술개발이 한층 요구되는 시점이다.In addition, due to the function of biodiversity, the inertness of protozoa and welfare animals due to excessive breeding of bacteria is low, so that the effectiveness of microbiological effects between microorganisms is small, and the transparency (clearness) of treated water is lowered, which does not reduce the amount of surplus sludge. It is a time to increase the burden and to be a factor of water pollution, which requires further technological development.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로 그 목적으로는 혐기성 및 임의성, 호기성, 변형호기성 미생물이 단계별 정화기능과 유입부하 정화 대응특성에 따라 우점 서식할 수 있는 생물막 접촉상을 각 실별 특성으로 구분 충진시키고 단일특성의 정화시설을 복합특성의 생물상 기능으로 전환시키며 1차침전조(E)의 질산화 슬러지를 무산소 유량조정조(B)로 이송 C/N비 조정에 의한 (탄소 대 질소의 비가 1.5-5) 탈질기능의 증대와 최종산화가 완료된 2차 침전슬러지를 혐기화 증대 기능으로 혐기분해조(A)로 이송 안정화된 이후 인출하는 기능을 부여 유기물 외 탈인 ·탈질 기능의 효율을 증대하고자하며, 또 생물막 분리를 위한 침전기능을 완벽하게 할 수 있는 침전실을 단계별 마감공정에 부가 생물상의 특성조정 및 잔여이물질로부터 최종 처리수를 보호하고 정화율을 지속적으로 높일 수 있는 처리방법과 장치를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the purpose of which is to identify the biofilm contact phase that anaerobic and randomness, aerobic, modified aerobic microorganisms can be predominantly inhabited according to the step-by-step purifying function and the influent load purification characteristics Filling by characteristics, converting a single-character purification facility into a biological function of a complex characteristic, and transferring nitrate sludge from the primary sedimentation tank (E) to an oxygen-free flow control tank (B) by adjusting the C / N ratio (the ratio of carbon to nitrogen 1.5-5) Increase the denitrification function and give the function of taking out the secondary settling sludge after final oxidation has been transferred to the anaerobic digestion tank (A) after stabilization to increase the efficiency of dephosphorization and denitrification function besides organic matter. In addition, the sedimentation chamber, which can complete the sedimentation function for biofilm separation, is added to the finishing process step by step. To provide a processing method and apparatus which can protect the can end processing and increasing the removal rate it is an object continuously.

상기 목적을 달성하기 위한 본 발명은 생활오수에 포함된 협잡물이나 고형성 유기물을 중력차에 의해 분리시키고 분리저장된 협잡물을 일정시간 저장하면서 최종침전조(H)로부터 이송된 산화된 잔존 슬러지와 함께 혐기 분해하면서 탈인이 진행되고 하부의 침전물은 인출되어 오니저장조(K)로 저장된다.The present invention for achieving the above object is anaerobic decomposition with oxidized residual sludge transferred from the final settling tank (H) while separating the contaminants or solid organic matter contained in domestic sewage by gravity difference and storing the stored contaminants for a certain time While dephosphorization proceeds, the lower precipitate is withdrawn and stored in the sludge storage tank (K).

이후 혐기균의 임의화 전환기능인 무산소 유량조정조(B)에 유입된 오수는 1차침전조(E)의 질산성 흡수 슬러지를 공급받고 미량의 교반용 리프트형 순환장치(B1)의 폭기수에 의해 혐기화를 임의화시켜 탈질을 증대시키는 작용을 하며, 탈질균의 배가시간 증대를 위한 생물막 안식기능의 파상단관 접촉재(B3)를 우측 유출구 방향에 고정 충진시켜 생물상의 초기구성 및 보유특성을 증대하면서 순간 과다 유입된 유량은 소량씩 이송리프트(B2)를 경유 조절되어 다음 공정으로 이송된다.Subsequently, the sewage flowing into the anaerobic flow rate adjusting tank B, which is a randomization conversion function of the anaerobic bacteria, is supplied with the nitrate absorbing sludge of the first settling tank E, and is anaerobic by the aeration water of a small amount of the lift type circulating device B1 for stirring. It randomizes ignition to increase denitrification, and fixedly fills the rupture tube contact material (B3) with biofilm repose function to increase the doubling time of denitrifying bacteria in the direction of the right outlet, while increasing the initial composition and retention characteristics of the organism. Instantaneous excess flow rate is controlled by the small amount via the transfer lift (B2) to be transferred to the next process.

이후 유기물 주처리 공정인 접촉폭기1ㆍ2실(C, D)에서 활성이 우수한 호기계 미생물에 의해 단계별 특성으로 유기물 분해 및 질소ㆍ인 흡수기능을 하기 위하여 접촉폭기조1실에 파상단관 접촉재(B3 또는 C3)를 충진하여 부착성 MISS(부착성 미생물)유지율 증대 및 파상면의 외부파상면(B3-1), 내부파상면(B3-2)에 미생물의 안식기능 부여특성으로 세균류의 기반을 증대시켜 유기물의 분해율을 최대화시킨다.Afterwards, in order to decompose organic matter and absorb nitrogen and phosphorus by step-by-step microorganisms having excellent activity in contact aeration 1,2 chambers (C, D), an organic main treatment process, a wave-like tube contact material is used in one aeration tank. B3 or C3) is used to increase the retention rate of adherent MISS (adherent microorganisms) and to provide microbial repose function to the external corrugated surface (B3-1) and internal corrugated surface (B3-2). Increase to maximize the decomposition rate of organic matter.

그 이후 형성된 처리수내에 수많은 세균류를 기반으로 편이 공생적 우점생물상 구현을 위한 전개 레이스형 단섬섬유사 발포막 코팅 접촉재(D1)를 고밀도 범위로 접촉폭기조2실(D)에 현수 충진시켜 폭기수와 발포막 코팅된 섬유사를 접촉시키면 유기물류의 제거 기초인 세균류의 배양과 원생, 후생동물의 우점특성에 기틀을 다진다.Subsequently, the developed race-type short-fiber fiber foam coated contact material (D1) is suspended in the contact aeration tank 2 (D) in a high density range based on a large number of bacteria in the treated water. When the contact with the fiber membrane coated with the foam membrane lays the foundation for the cultivation of bacteria, which is the basis for the removal of organic matter, and the predominant characteristics of protozoa and epigenetics.

2단계 최종공정의 1차침전조(E)는 생물상 구분을 위한 침전기능에 의한 분류공정으로 침전 질산화물을 인출하여 연속공정으로 무산소유량조정조(B)로 이송 순환되면서 질소, 인이 흡수 제거되고 2단계 산화공정을 지속시키는 기능을 한다.The first sedimentation tank (E) in the final stage of the second stage is a sorting process based on the sedimentation function for biodiversity, and the nitrogen and phosphorus are absorbed and removed while being circulated to the anoxic flow rate adjustment tank (B) in a continuous process. It functions to sustain the oxidation process.

상등수는 3단계 공정의 간헐폭기조1실 및 2실(F, G)로 유입되며, 3단계 공정의 저부하 특성에 유기물 농도에 따른 최종 유기물 제거공정으로 간헐폭기조1실(F)에 발포막 코팅 전개 레이스형 단섬섬유사 발포막코팅 접촉재(F1 또는 D1)를 충진하고 간혈폭기조2실(G)에 다섬사에 의한 전개 레이스형 다섬섬유사 접촉재(G1)를 충진하여 상호 현수 발포막 코팅 단섬사의 발포막코팅(D1-3)과 다섬사 사면(G1-3)특성의 공극비를 각기 살려준다.The supernatant flows into the intermittent aeration tank 1 and 2 chambers (F, G) of the three-step process, and the foam film is coated on the intermittent aeration tank (F) as the final organic matter removal process according to the organic matter concentration due to the low load characteristics of the three-step process. Cross-suspended foam film coating is performed by filling the expanded lace type single-fiber yarn coated membrane coating material (F1 or D1) and filling the two hepatic astrocytes (G) with the developed lace-type multi-fiber yarn contact material (G1). The porosity ratio of single-foamed foam coating (D1-3) and multi-threaded slope (G1-3) is saved.

즉, 생물상의 복합특성을 인위적으로 조정키 위한 간헐폭기조1, 2실(F, G)의 전자제어밸브(F2, G2)에 의한 간헐폭기공정으로 응집 및 솎음효과 증대와 유기성계 오염물의 최종 분해 및 영양염류인 질소ㆍ인의 산화기능을 최대로 이룬 이후 최종침전실(H)로 유입되면서 분리된 최종 슬러지는 인발되어 혐기 분해조(A)에 이송 후 제처리공정을 경우 최종공정으로 인발 제거되면서 처리수는 유출된다.In other words, the intermittent aeration process by the intermittent aeration tanks 1 and 2 chambers (F, G) electronic control valves (F2, G2) to artificially adjust the complex characteristics of the biomechanism increases the coagulation and damping effect and the final decomposition of organic contaminants And the final sludge separated into the final sedimentation chamber (H) after maximizing the oxidizing function of nitrogen and phosphorus, which is nutrients, is drawn and transferred to the anaerobic digestion tank (A). Treated water flows out.

도면을 참고로 하여 상세히 설명하면 다음과 같다.Referring to the drawings in detail as follows.

처리공정은 혐기분해조(A), 무산소 유량조정조(B), 접촉폭기조1실(C), 접촉폭기조2실(D), 1차침전조(E), 간헐폭기1, 2실(F, G), 최종침전조(H), 소포조(I), 소독방류조(J)등과 별도의 오니저장조(K) 등으로 구성되며, 1단계 공정의 혐기분해조(A)에 유입된 오수는 유입수유도장치(A1)을 경유유도관에 의해 조하부의 혐기층에 이송되어 혐기층 침전물에 확산되면서 하부의 침전물과 유입수가 접촉 탈인율을 증대하며 상부 스캄층의 협잡물을 교란시키지 아니하고 유입된다.Treatment process is anaerobic digestion tank (A), oxygen free flow control tank (B), contact aeration tank (C), contact aeration tank (D), primary sedimentation tank (E), intermittent aeration tank (F, G) ), Final sedimentation tank (H), defoaming tank (I), disinfection and discharging tank (J), and separate sludge storage tank (K), etc., and sewage flowing into anaerobic digestion tank (A) of the first stage The device A1 is transferred to the anaerobic bed at the bottom of the tank by a diesel induction pipe and diffused into the anaerobic sediment while the lower sediment and the influent increase the contact dephosphorization rate and are introduced without disturbing the contaminants of the upper skim bed.

이때 고형성 유기물이나 협잡물은 부상이나 침전 등을 스스로 비중차에 의해 선택하며 내부에 존재된 혐기성 미생물류 및 최정침전조(H)에 질산화 이후 인발 이송된 최종 공정슬러지에 의해 탈인, 유기물 분해 및 혐기 기능의 공정이 진행되면서 정류장치(A4)의 유출공을 경유 무산소 유량조정조(B)로 유입된다.At this time, solid organic matter and contaminants are selected by specific gravity difference by flotation or sedimentation, and dephosphorization, organic matter decomposition and anaerobic function by anaerobic microorganisms existing inside and final process sludge transferred after nitrification to the final settling tank (H). As the process proceeds, the outflow hole of the stop value (A4) is introduced into the anoxic flow rate adjusting tank (B).

무산소 유량조정조(B)에 유입된 오수는 리프트형 순환장치(B1)에 의해 완속적 교반 및 혐기성 특성을 임의성 무산소계 유지로 탈질기능과 임의성계로 배가시간이 짧은 탈질균의 안착을 위한 파상단관 접촉재(B3)를 유출라인 방향에 충진시켜 파상단관의 관내 수리안정기능과 관의 굴곡부의 생물막 안식기능을 부가 비증식 속도와 배가시간이 짧은 탈질균의 증식배양을 한층 증대시켜 안정적 탈질기능을 유도한다.Sewage flowed into the anaerobic flow rate adjustment tank (B) is a broken pipe for the settling of denitrification bacteria that has a short decay time to a denitrification function and an arbitrary system by maintaining a random aerobic system with a slow stirring and anaerobic characteristics by a lift type circulation device (B1). Filling the contact material (B3) in the direction of the outflow line adds the functional stability of the tube in the tubular tube and the biofilm rest function of the bent portion of the tube to further increase the non-proliferation rate and the growth of denitrifying bacteria with short doubling time. Induce.

그리고 1차침전조(E)로부터 이송된 침전물은 질산성 질소를 다량 함유하여 유입수의 유기탄소원과 C/N비를 유지시켜 탈질공정에 질산화물을 공급하므로써 무산소 조건에서 탈질미생물의 호흡과정의 질산성 질소를 질소가스로 전환 탈질을 최대화시켜주는 기능을 하게 된다.The sediment transferred from the primary sedimentation tank (E) contains a large amount of nitrate nitrogen and maintains the C / N ratio of the influent water to supply nitrates to the denitrification process, thereby supplying nitrates in the respiratory process of the denitrification microorganisms under anoxic conditions. Is converted to nitrogen gas to maximize the denitrification.

또 유입유량의 편화성을 평균화시켜 주기 위한 유량조정용 에어리프트식 이송장치(B2) 등을 구성 유입량 조절 및 유량특성의 질을 평균화시키면서 차기공정으로 이송한다.In addition, an air lift type feeder B2 for adjusting flow rate for averaging the ease of inflow flow rate is transferred to the next step while adjusting the inflow rate and averaging the quality of flow rate characteristics.

이후 2단계 공정의 유기물의 주처리공정인 접촉폭기조1실(C)은 하부에 산기장치(C1)와 그 상부에는 여재형틀(C2) 및 파상단관 접촉여재(C3)가 전체용적의 60%범위로 밀착 충진되며 양면이 열린 파상단관 내 외부의 굴곡에 혐기균과 호기균의 배양 및 보유기능을 구성하여주며 무방향성 충진으로 폭기수의 공기이전율 증대 및 생물막의 보유특성 증대로 기능이 이어진다.Thereafter, the contact aeration tank 1 chamber (C), which is the main treatment process of the organic matter in the second step, has an air diffuser (C1) at the lower part and a filter frame (C2) and a waveguide tube contact medium (C3) at the upper part of the total volume of 60%. It consists of the incubation and retention functions of anaerobes and aerobic bacteria in the outer bend inside the open tube on both sides, and the function is continued by increasing the air transfer rate of the aeration water and the retention of the biofilm.

접촉폭기조2실(D)은 단섬사재질의 전개 레이스형 망사형 구조를 갖는 전개 레이스형 단섬섬유사 발포막 코팅접촉재(D1) 즉, 섬유사를 나열 현수시키고 그 표면에 액상의 폴리우레탄을 분사 화학반응에 의한 발포상형성으로 발포상에 미세한 공극을 형성시킨 발포막 코팅 섬유사 접촉재(D1)를 충진함으로서 호기성계의 형성기전율 증대 및 생물상의 기틀을 보강하여 주며 유기물의 주분해 및 N, P 산화 기능증대를 하게 된다.The two contact aeration tanks (D) suspend the suspended lace type single-fiber yarn coated membrane coated contact material (D1), that is, the fibrous yarn, and have a liquid polyurethane on the surface thereof. By filling the foamed membrane-coated fiber yarn contact material (D1), which forms fine pores on the foamed phase, by forming a foamed phase by spraying chemical reaction, it increases the formation mechanism of aerobic system and reinforces the biological structure, and the main decomposition of organic matter and N P increases oxidative function.

내부 충진물에 있어 접촉폭기조1, 2실중 1실은 프라스틱계 파상단관접촉재(C3)를 충진하여 생물막의 파상단관내 굴곡부의 안식기능과 파상단관상의 내부 수리흐름 부하저감 기능으로 생물막의 안식력이 뛰어나며 접촉폭기조2실(D)은 현수상의 전개 레이스형 단섬섬유사에 액상의 우레탄을 여재표면상에 여재를 구심체로 발포고정시켜 섬유사면의 단순성을 불규칙한 다공성 돌출면으로 변형 생물막의 다공내 서식과 표면부착율 증대 및 비가역 부착특성 강화와 돌출된 전개레이스에 생물막의 확창기틀과 과부착시 박리율을 조정하며 망사표면의 생물막 보유율 유지기능으로 전체적인 미생물 보유율 증대 및 박리시 표면우레탄의 다공성 돌출면에 의해 박리율의 2차조정과 미생물의 종균기틀을 발포막 내부에 추가로 형성함으로 유기물의 제거기능을 부가시키며 안정적인 F/M비로 처리율 향상과 생물상의 안정을 유지한다.In the inner packing, the contact aeration tanks 1 and 2 rooms are filled with plastic waveguide tube contacting material (C3), and the stability of the biofilm is reduced by the function of relieving the load on the bent portion of the waveguide tube and reducing the internal repair flow on the waveguide tube. The excellent contact aeration tank 2 (D) is a foamed lace-type single-fiber yarn suspended in suspension, and a liquid urethane is fixed by foaming the media on the surface of the media with a centripetal body. Increasing surface adhesion rate and reinforcing irreversible adhesion characteristics and adjusting the expansion mechanism of the biofilm on the overhanging development race and the peeling rate when over-adhesion, and maintaining the biofilm retention rate on the mesh surface to increase the overall microbial retention rate and by the porous protruding surface of the surface urethane Secondary adjustment of the peel rate and additional spawning framework of microorganisms are formed inside the foam membrane to remove organic matters. In addition, it maintains the stability of biomass and improves throughput with stable F / M ratio.

생물상 특성분리를 위한 1차침전조(E)를 경유 생물상의 특성을 분리하며 질산화된 부유물을 침전하고 침전물은 인출되어 무산소 유량조정조(B)로 에어리프트(E2)를 경유 반송시켜 유기탄소원과 질산성 질소의 C/N비를 유지시키고 탈질공정에 질산화물을 공급하는 기능을 한다.The primary sedimentation tank (E) for biological characterization separates the characteristics of the biomass, precipitates the nitrified suspended matter, and the precipitate is withdrawn and returned to the oxygen-free flow control tank (B) via the air lift (E2) via organic carbon source and nitric acid. It maintains the C / N ratio of nitrogen and supplies nitric oxide to the denitrification process.

그러므로 무산소 조건에서 탈질 미생물의 호흡과정에서 질산성질소를 질소가스로 전환 탈질을 유도하는 기능으로 순환 재이용되면서 2단계 처리수를 분류한다.Therefore, during the respiration process of denitrification microorganisms under anoxic conditions, the two-stage treated water is classified while being recycled and recycled as a function of inducing denitrification to nitrogen gas.

3단계 공정에 유입된 2단계 유기물 분해가 완료된 처리수는 3단계 공정으로 물속에 용존된 산소를 소비하면서 전개 레이스형 단섬유사 발포막코팅접촉재(F1)가 충진된 간헐폭기조1실(F)에는 전자제어밸브(F2)에 의해 자동 조절되는 산소공급기능 작용에 의해 용존산소 변화에 따른 응집기능과 유기물 분해기능을 이루며 2단계공정의 접촉폭기조2실(D)의 기능을 3단계 간헐폭기조1실(F)의 기능으로 서서히 전환되면서 자립특성 및 전공정에 잔존한 세균류를 먹이원으로 원생ㆍ후생동물의 증식이 활발히 진행되어진다.The treated water in which the two-stage organic matter decomposed into the three-stage process is completed is a three-stage process, while consuming oxygen dissolved in the water, one intermittent aeration tank filled with the expanded lace type single fiber yarn foam membrane coating contact material (F1) (F1). ), The oxygen supply function automatically controlled by the electronic control valve (F2) is used to achieve the coagulation function and organic matter decomposition function according to the dissolved oxygen change, and the function of the contact aeration tank 2 chamber (D) in the two-step process is a three-step intermittent aeration tank. As it gradually transitions to the function of one chamber (F), proliferation of protozoa and welfare animals is actively progressed as a food source using independence characteristics and bacteria remaining in the previous process.

이후 간헐폭기조2실(G)의 다섬섬유사 현수면을 갖는 전개 레이스형 다섬유사 접촉재(G1)가 충진되며 제어기능에 의한 간헐폭기로 미세한 섬유사 표면 및 전개 레이스형상을 갖는 섬유사의 외부생물막과 섬유사 내부에 미세한 표면층의 호기성 생물막이 공유효과를 이루며 감소된 미생물의 먹이특성에 의해 응집효과가 증대되어 응집력을 향상시키는 기능을 한다.After that, the development lace type multifiber yarn contact material G1 having multi-island fiber yarn suspension surface of two intermittent aeration tanks (G) is filled, and the external surface of the fiber yarn having the fine fiber surface and the development lace shape by the intermittent aeration by the control function. The aerobic biofilm of the fine surface layer inside the biofilm and the fiber yarns has a shared effect, and the cohesive effect is enhanced by the reduced microbial feeding characteristics, thereby improving the cohesive force.

그러므로 원생동물에 의한 세균류의 먹이사슬에 의한 솎음효과를 극대화시켜 처리수의 침전성 증대를 도모한다.Therefore, by maximizing the damping effect of the food chain of bacteria by protozoa, the sedimentation of the treated water is increased.

응집된 오수가 유입되는 침전실의 정류장치는 응집물과 처리수를 중력침전으로 분류시켜 처리수는 수리부하가 저감된 월류웨어를 경유 유출되고 하부침전응집물은 홉파에 의해 포집, 인발에어리프트를 경유 1차 혐기분해조를 거쳐 오니저장조에 저장된다.The stop of the sedimentation chamber where the condensed sewage flows into is classified into the coagulation and treated water by gravity settling.The treated water is discharged through the overflowware with reduced hydraulic load, and the lower sedimented agglomerate is collected by the hop wave and passes through the drawing airlift. It is stored in a sludge storage tank through a tea anaerobic digester.

이후 최종 처리수는 소독방류조를 경유 배출되며 이때 배출된 처리수는 생물학적 특성의 최후단계 정화효과를 나타낸다.After that, the final treated water is discharged through the disinfection tank, and the discharged water shows the last stage purification effect of biological characteristics.

Increasing the microbial linkage rhythm by inducing accessibility to.

또 조의 전단계에 과도한 세균류배양에 따른 편이 공생적 후생동물의 우점특성이 조의 후단으로 갈수록 먹이사슬로 강하게 이어지는 기능을 증대키 위해 통수성과 박리성이 우수한 전개 레이스형 섬유사 현수재로 충진하여 후생동물계의 우점화를 증대시켜주어 잉여부산물인 슬러지 발생량 감소 및 처리효율을 크게 높일 수 있는 특징으로 대두되어 유지관리비가 한층 저감된다.In addition, the predominant characteristics of symbiotic welfare animals in the early stage of the tank are filled with the development of lace-type fiber yarn suspension with excellent water permeability and peelability in order to increase the continuity of the symbiotic welfare animals to the food chain. The maintenance cost is further reduced by increasing the dominance of the product, and reducing the amount of excess by-product sludge and increasing the treatment efficiency.

이상에서 설명한 바와 같이 본 발명은 혐기성 및 호기성 미생물이 단계적으로 서식할 수 있는 각기에 공간을 형성하여 주는 혐기. 임의. 호기접촉단계와 이후 생물상의 복합적 구성요율을 결정짓는 우레탄 발포막접촉재를 중심기능에 충진하고 3단계 기능으로 분류된 각실별 특성의 접촉상을 상호연계 단일공정에서 변화를 주게된다.As described above, the present invention provides anaerobic anaerobic and aerobic microorganisms that form a space in each of which can inhabit step by step. option. The urethane foam membrane contact material, which determines the composite composition rate of the aerobic contact step and subsequent biologics, is filled in the central function, and the contact phase of each room classified into the three step functions is changed in an interconnected single process.

그 효과로 단계별 분류에 의한 여건변화시 미생물의 빠른 접근성기전기능을 유도함으로써 생물상의 정량적 증대 및 정성적 특성화한 기능과 2차침전실 후에 간헐폭기의 응집과 자립성기능을 형성하고 유기물의 최종분해 응집 및 수계영양염류의 근원인 T-N, T-P의 분해와 흡착율이 가일층 향상되어 있으며, 미생물의 신진대사 리듬곡선을 실별특성에서 소화 흡수하여 고효율의 정화효과를 기할 수 있었다.As a result, quantitative increase and qualitative characterization of the biomass and the intermittent aeration flocculation and independence function after the secondary settling chamber by inducing the rapid accessibility mechanism of microorganisms during the change of conditions by the stepwise classification And the decomposition and adsorption rate of TN and TP, which are the source of aquatic nutrients, are further improved, and the metabolic rhythm curve of microorganisms can be digested and absorbed in the real-world characteristics to achieve high efficiency purification effect.

또한 1차 침전분리된 질산화계의 침전슬러지를 인출하여 무산소유량 조정조로 이송 질산화물 공급에 따른 탈질효과와 호기성 생물막의 SS부하를 증가시켜 접촉폭기조1, 2실의 생물막 증대역할로 유도되는 기능을 한다.In addition, the precipitated sludge of the first sedimented and separated nitrification system is taken out and the denitrification effect of the transfer nitrogen oxide supply to the anoxic flow rate adjusting tank is increased, and the SS load of the aerobic biofilm is increased to induce the role of increasing the biofilm in the contact aeration tanks 1 and 2. .
