The fixed bed anaerobic reactor 2 filled with the media 10 and the stirrer 11 and the fixed bed anaerobic reactor 4 and the media 14 filled with the media 12 and the stirrer 12 were filled and acid It consists of a stationary phase aerobic reactor (6) and a settling tank (9) with an engine (8) and a deoxidation column (20). At the same time the initial influent wastewater (1) is introduced into the anaerobic reactor (2). A portion of the first influent wastewater (1) is introduced into the anaerobic reactor (4) via the bypass flow line (3), the sludge is precipitated in the settling tank (9) through the aerobic reactor (6) in the anoxic reactor (4), and the supernatant is discharged. In the air supply unit (7) to the aerobic reaction tank (6) using a diffuser to aeration oxygen, a cylindrical deoxygenation column 20 is installed at the bottom of the outlet 22 and the lower portion of the deoxygenation column (2) Internal return line 16 is installed and internal circulation in aerobic reactor 6 The pump 15 sends the internal conveying line 16 to the oxygen-free reaction tank 4 and some sludge in the settling tank 9 can be selectively transported to the anaerobic reaction tank 2 by the external circulation pump 17. . Reference numeral 18 denotes a methane gas collector and 19 denotes a nitrogen gas.

이와같이 된 본 발명은 유기물 및 질소, 인을 포함한 폐수가 최초 유입 폐수(1)를 혐기성 반응조(2)로 유입시키고 혐기성 반응조(2)의 유출수는 무산소 반응조(4)를 통하여 호기성 반응조(6)를 지나 침전조(9)에서 질소, 인 섭취 및 유기물 분해 과정에서 발생한 슬러지를 침전시키고 처리된 상등수는 방류시킨다. 상기의 공정에 있어 최초 유입폐수(1)의 일부는 우회 흐름 라인(3)을 통하여 혐기성 반응조(2)를 통하지 않고 직접 무산소 반응조(4)로 유입시켜서 탈질과정에서 요구되는 탄소원의 공급역활을하여 전체적인 처리효율을 향상시킬 뿐만아니라 혐기성 반응조(2)의 용량을 축소시켜 소유부지면적과 제작비를 절감할수 있으며 최초 유입폐수(1)의 우회 유입으로 탈질효율의 상승과 무산소 반응조(4)에서 인의 섭취가 효과적이서 인의 제거율을 증가시킬수 있다.According to the present invention, the wastewater containing organic matter, nitrogen, and phosphorus is introduced into the anaerobic reactor (2) and the effluent of the anaerobic reactor (2) is aerobic reactor (6) through an anaerobic reactor (4). In the sedimentation tank 9, sludge generated during nitrogen, phosphorus intake and organic decomposition is precipitated and the treated supernatant is discharged. In the above process, a part of the initial inflow wastewater (1) flows directly into the anaerobic reaction tank (4) through the bypass flow line (3) without passing through the anaerobic reaction tank (2), and serves as a supply source of the carbon source required in the denitrification process. In addition to improving the overall treatment efficiency, the capacity of the anaerobic reactor (2) can be reduced to reduce the land area and production cost.In addition, the denitrification efficiency and the intake of phosphorus in the anaerobic reactor (4) are increased due to the inflow of the first influent wastewater (1). Can be effective in increasing the removal rate of phosphorus.

그리고 호기성 반응조(6)는 공기공급장치(7)와 산기관(8)을 통해 충분한 산소를 공급할 수 있으며 각 반응조(2)(4)(6)의 메디아(10)(12)(14)는 충분한 미생물을 확보할 수 있도록 적절한 부피비로 충진시킨다. 최초 유입 폐수(1)는 혐기성 반응조(2)에 충진된 메디아(10)의 미생물에 의한 폐쇄를 방지하고 미생물과 원활한 접촉을 위해서 혐기성 반응조(2)의 최하단으로 유입되어 상부로 유출되게 하며 완전 혼합을 위하여 교반기(11)를 작동시키며 혐기성 반응조(2)에서 처리되는 과정에서 발생된 부산물인 메탄가스는 가스포집기(18)에 의해 별도로 포집되는 것이다.In addition, the aerobic reactor 6 may supply sufficient oxygen through the air supply device 7 and the diffuser 8, and the media 10, 12, 14 of each reactor 2, 4, 6 may be Fill in appropriate volume ratios to ensure sufficient microorganisms. The first inflow wastewater (1) is introduced into the bottom of the anaerobic reactor (2) and flows out to the top to prevent the closure by the microorganisms of the media (10) filled in the anaerobic reactor (2) and to flow out to the top and completely mixed By operating the stirrer 11 for the methane gas by-product generated in the process in the anaerobic reactor (2) is to be collected separately by the gas collector (18).

상기의 공정을 통해 혐기성 반응조(2)에서 유출된 폐수는 우회 흐름 라인(3)을 통한 최초 유입폐수(1)와 함께 무산소 반응조(4)의 상부로 유입되어 지며 이때 무산소 반응조(4)는 호기성 반응조(6)에서 내부 순환 펌프(15)에 의해 순환된 폐수와 함께 교반기(13)에 의해 혼합되어 지며 역시 충진된 메디아(12)에 부착된 다량의 미생물에 의해 폐수내의 오염물질이 제거되어지며 이때 발생되는 부산물인 질소가스(19)는 대기중으로 배출된다.Wastewater flowing out of the anaerobic reactor 2 through the above process is introduced into the upper portion of the anaerobic reactor 4 with the first influent wastewater 1 through the bypass flow line 3, where the anoxic reactor 4 is aerobic The contaminants in the wastewater are mixed by the agitator 13 together with the wastewater circulated by the internal circulation pump 15 in the reactor 6 and also attached to the filled media 12. Nitrogen gas (19), a by-product generated at this time, is discharged into the atmosphere.

상기공정에서 유출된 폐수는 호기성 반응조(6)로 유입되어지며 메디아(14)에 부착된 다량의 미생물에 의해 폐수내의 오염물질을 제거시키며 미생물의 활성을 향상시키기 위하여 공기공급장치(7)에서 산기관(8)을 통해 호기성 반응조(6)를 폭기시키며 호기성 반응조(6)를 거쳐 방류시킨다. 상기 공정에서 일반적인 생물학적 영양염 제거공정에서는 호기성 반응조(6)에서 무산소 반응조(4)로 탈질화를 위한 내부 순환수 중의 DO 농도 유입이 무산소 반응조(4)에서의 탈질화를 저해하는 요인으로 작용하기 때문에 내부 순환수 중의 DO 농도 저감을 위하여 탈산 반응기를 설치하는 경우가 많은데 본 발명에서는 별도의 반응기를 설치하지 않고 호기성 반응조(6)의 내부 반송 라인(21)을 연결하여 내부 반송이 이루어 지도록 하였다.Wastewater discharged from the process is introduced into the aerobic reactor (6) to remove contaminants in the wastewater by a large amount of microorganisms attached to the media (14) and acid in the air supply device (7) to improve the activity of the microorganisms The aerobic reactor 6 is aerated through the engine 8 and discharged through the aerobic reactor 6. In the general biological nutrient removal process in the above process, the DO concentration in the internal circulating water for denitrification from the aerobic reactor 6 to the anaerobic reactor 4 acts as a deterrent to the denitrification in the anaerobic reactor 4. In many cases, a deoxidation reactor is installed in order to reduce DO concentration in the internal circulating water, but in the present invention, the internal conveyance is performed by connecting the internal conveying line 21 of the aerobic reactor 6 without installing a separate reactor.

상기 탈산소 칼럼(2)은 DO 농도의 저감 뿐만아니라 유출구 (22)로 빠져 나가는 슬러지의 일부가 탈산소 칼럼(2)의 하부에 축적되어 내부 반송 라인(21)을 통해 무산소 반응조(4)로 반송되기 때문에 무산소 반응조(4)로의 슬러지 반송역활도 동시에 수행하는 효과를 기대할 수 있다.The deoxygenation column (2) not only reduces the DO concentration but also a portion of the sludge exiting the outlet (22) is accumulated in the lower portion of the deoxygenation column (2) to the oxygen-free reaction tank (4) through the internal conveying line (21). Since it is conveyed, the effect which performs the sludge conveyance role to the oxygen-free reaction tank 4 simultaneously can be expected.

상기의 호기성 반응조(6)에서 유출된 폐수는 침전조(9)에서 침전되어 상등수는 방류되고 침전된 슬러지의 일부는 필요에 따라 외부 순환 펌프(17)에 의해 혐기성 반응조(2)로 이송되어 지며 나머지 일부는 잉여 슬러지로 처분되어 지는 것이다.Waste water flowing out of the aerobic reactor 6 is precipitated in the settling tank (9), the supernatant is discharged, and a part of the sludge is transferred to the anaerobic reactor (2) by an external circulation pump (17), if necessary, the rest Some are disposed of as excess sludge.

그러므로 본 발명은 폐수 중의 유기물 제거와 동시에 질소와 인을 단시간에 처리할 수 있게 하여 처리효율을 중대시키고 유입폐수의 수질변화에 따른 적응력이 강하여 운전유지가 쉽고 동력비도 절감시키고 폐수의 우회흐름 라인을 적용하여 반응조의 용량을 축소할수 있어 부지를 절감시킬수 있는 등의 효과가 있는 것이다.Therefore, the present invention enables the treatment of nitrogen and phosphorus in a short time as well as the removal of organic matter in the waste water, which greatly improves the treatment efficiency and the strong adaptability according to the water quality change of the influent waste water, which makes it easy to maintain the operation, reduce the power cost and improve the bypass flow line of the waste water. It is possible to reduce the capacity of the reactor by applying the effect, such as to reduce the site.
