본 발명은 하수중에 함유된 질소와 인을 제거하기 위하여 고정 여재를 설치한 연속회분식 반응조(sequencing batch reactor: SBR)에 관한 것으로, 특히 본 발명은 하수를 고도 처리하기 위하여 다공 파이프 상에 섬모상 여재를 부착시켜 운전 되도록 한 연속회분식 반응조로서, 하수 유입, 반응, 침전, 처리수 유출, 슬러지 제거가 모두 또는 선택적으로 이루어지며, 미생물이 섬모상 여재와 다공 파이프 내부에 고정되어 있어 기존의 부유성 미생물을 이용한 연속회분식 반응조에 비하여 처리수 유출 단계에서 슬러지가 떠오르는 문제를 최소화 할 수 있는 장점을 가진 하수 고도처리 방법에 관한 것이다.The present invention relates to a sequencing batch reactor (SBR) in which a fixed filter medium is installed to remove nitrogen and phosphorus contained in sewage. In particular, the present invention relates to a ciliary filter medium on a porous pipe for highly treating sewage. It is a continuous batch reactor that is operated by attaching sewage, sewage inflow, reaction, sedimentation, treated water outflow, sludge removal are all or selectively made. Compared to a continuous batch reactor using the present invention relates to a sewage advanced treatment method having the advantage of minimizing the problem of sludge rise in the treated water outflow step.

하수중에 포함된 영양염류 물질인 질소와 인은 일반적으로 발생 장소에서 적절하게 처리되지 않고 하천 및 호소에 유입된다. 이와 같이 유입된 영양염류는 하천 및 호소에서 부 영양화를 유발하며, 조류의 이상 증식의 원인이 되는 등, 결국에는 하천, 호소와 같은 수자원의 관리에 큰 장애요인이 되고, 이를 원수로 취수하는 정수장에서, 정수처리 비용이 증가하는 등 많은 경제적 손실을 초래하게 된다.Nitrogen and phosphorus, nutrients contained in sewage, generally enter streams and lakes without proper treatment at the site of generation. The nutrients introduced in this way cause side nutrients in rivers and lakes and cause abnormal growth of algae, and eventually become a major obstacle to the management of water resources such as rivers and lakes. In a water treatment plant, there are many economic losses, such as increased water treatment costs.

일반적으로 국내 대규모 하수처리장과 소규모 마을 하수도의 경우, 수처리 기술은 접촉 여재를 충진하거나 혹은 충진하지 않고 포기시키는 활성슬러지 시스템을 98 ％ 이상 사용하고 있다.In general, in the case of large domestic sewage treatment plants and small village sewage systems, water treatment technology uses more than 98% of activated sludge systems that fill or dispose of contact media.

특히, 오수처리는 장기 포기 형태의 활성 슬러지 시스템으로 운영되고 있으나 이러한 처리방법은 질소의 경우 유기성 및 암모니아성 질소를 아질산성 혹은 질산성 질소 형태로 변환시킬 뿐 양적으로 감소시키는 최종처리는 기대할 수 없으며, 인의 처리 효율도 저조하여 수자원 보호를 위한 수질관리에 큰 문제점으로 지적되고 있다.In particular, sewage treatment is operated as an activated sludge system in the form of long-term aeration, but such treatment method converts organic and ammonia nitrogen into nitrous or nitrate nitrogen form in the case of nitrogen, but cannot expect a final treatment. In addition, the treatment efficiency of phosphorus is low and it is pointed out as a big problem in water quality management for water resource protection.

또한, 일반 가정이나 큰 규모의 건물등에 설치한 정화시설은 대부분 유기물만 처리하는 공정으로 구성되어 있고, 유지관리에 많은 경제적 부담을 안고 있다.In addition, most of the purification facilities installed in homes and large-scale buildings consist of a process for treating only organic matters, and have a large economic burden on maintenance.

하수 고도처리 방법으로 최근 새로이 개발된 기술로서, 다양한 처리 공정들이 제시되고 있다. 이러한 처리 공정들은 대부분 바덴포(Bardenpho), A/O, A2/O 공법을 변형한 처리법으로 설계 및 운전 인자가 복잡하고, 처리 효율을 높이기 위하여 외부에서 유기물을 공급해 주어야 하기 때문에 경제적인 부담이 큰 단점이 있다.As a newly developed technology for the advanced sewage treatment method, various treatment processes have been proposed. Most of these treatments are modified from Bardenpho, A / O and A 2 / O methods, which are complicated in design and operation factors, and have to be supplied from the outside to improve treatment efficiency. There is a big disadvantage.

소규모 오수 처리방법에 이용되고 있는 기존의 연속회분식 반응조의 운영 방식은 일정시간 동안 반응조 내에 공기를 공급하지 않는 혐기성 조건에서 운영한 후, 다시 일정시간 공기를 공급하는 호기성 조건으로 운영하며, 상기 혐기성과 호기성의 조건을 반복한 후 성장한 미생물을 침전시켜 처리된 물을 방류시키는 방법이다.The existing continuous batch reactor used in small scale sewage treatment is operated under anaerobic conditions that do not supply air into the reactor for a certain time, and then operates under aerobic conditions that supply air for a certain time. After repeating aerobic conditions, the grown microorganisms are precipitated to discharge treated water.

상기 연속회분식 반응조는 유기물, 질소 및 인의 처리 효율도 비교적 우수한 것으로 밝혀져 있으나, 처리수를 유출하는 단계에서 슬러지가 떠오르지 않게 세심한 주의를 요하거나 고가의 유출장치를 필요로 하게 되며, 유기물이 부족한 경우에는 처리 효율이 저하되는 문제점을 가지고 있다.The continuous batch reactor has been found to be relatively excellent in the treatment efficiency of organic matter, nitrogen and phosphorus, but requires careful attention or an expensive outflow device in order to prevent the sludge from rising in the outflow of the treated water, if the organic matter is insufficient There is a problem that the processing efficiency is lowered.

본 발명은 하수중의 유기물, 질소 및 인을 효과적으로 처리할 수 있고, 운영비의 절감과 관리를 용이하게 할 수 있는 하수 고도처리 공정을 개발하기 위한 것으로, 본 발명의 목적은 단일 반응조상에 다공 파이프를 균일한 간격으로 배치하며, 다공 파이프 내부에 미생물의 부착을 촉진하기 위하여 다공 파이프에 다수의 다공을 형성하고, 다공 파이프 외부에 미생물의 부착을 촉진하기 위하여 섬모상의 여재를 부착시킨다. 이와같이 다공 파이프 내, 외부에 부착 성장한 미생물의 작용에 의해 하수중의 유기물, 질소 및 인을 효과적으로 제거하며, 운영 및 관리상의 효율을 향상시킬 수 있는 하수 고도처리 공정을 제공함에 있다.The present invention is to develop an advanced sewage treatment process that can effectively treat organic matter, nitrogen and phosphorus in sewage, and can reduce operating costs and facilitate management, and an object of the present invention is to provide a porous pipe in a single reactor. It is arranged at even intervals, to form a plurality of pores in the porous pipe to promote the attachment of microorganisms inside the porous pipe, and to form a ciliary media to promote the attachment of microorganisms to the outside of the porous pipe. As described above, the present invention provides an advanced sewage treatment process that effectively removes organic matter, nitrogen, and phosphorus from sewage by the action of microorganisms grown inside and outside the porous pipe, and improves operational and management efficiency.

이와 같은 목적을 달성하기 위한 본 발명은, 기존의 연속회분식 반응조 내의 부유 성장형 미생물 대신에 별도의 다공 파이프를 설치하여, 파이프 내부에 미생물 부착을 유도하고 파이프 외부에 섬모상 여재를 지지하도록 하며, 방류단계에서 슬러지 부상의 문제가 발생하지 않도록 한 것에 특징이 있다.The present invention for achieving the above object, by installing a separate porous pipe in place of the floating growth-type microorganisms in the existing continuous batch reactor, induce microbial adhesion inside the pipe and support the ciliary media outside the pipe, discharge It is characterized by preventing the problem of sludge injury at the stage.

The ciliary media 9 surrounding the porous pipe 6 serves as a carrier for fixing microorganisms, and the porous pipe 6 perforates a plurality of pores 8 to induce the flow of water into the porous pipes. The microbial membrane is formed on the inner surface of the porous pipe 6 through operation. This microbial membrane, together with the microorganisms grown on the ciliary media, ultimately exerts its effect on the removal of nitrogen, phosphorus and organics from the sewage.
