Description

폭기조{Aeration tank}Aeration tank

본 발명은 폭기조에 관한 것으로서, 특히 폐수처리시 유동성 담체를 투입하여 폐수의 유기물을 제거하는 폭기조에 관한 것이다.The present invention relates to an aeration tank, and more particularly, to an aeration tank for removing organic matter from wastewater by injecting a fluid carrier in treatment of wastewater.

일반적으로 가정, 축산농가, 산업현장 등에서 발생되는 하수, 오수 및 분뇨와 같은 폐수는 많은 양의 잔존물을 함유하게 된다.Generally, wastewater such as sewage, sewage, and manure generated in homes, livestock farms, and industrial sites contain large amounts of residues.

따라서, 잔존물이 포함된 폐수를 생물학적 및 화학적 산소요구량, 부유물질 함량 등이 환경기준치에 도달하지 않은 상태에서 배출하게 되면 토양이나 수질이 오염되게 된다.Therefore, when the waste water containing the residues is discharged in a state in which the biological and chemical oxygen demand, suspended solids content, etc. do not reach the environmental standard value, soil or water quality is contaminated.

이에 따라 폐수내의 잔존물을 생물학적, 물리적, 화학적 방법을 이용한 폐수정화처리장치를 통해 정화된 하천 등으로 방류함으로써 환경오염을 줄이게 된다.Accordingly, the residues in the wastewater are discharged to a purified stream through a wastewater purification apparatus using a biological, physical, or chemical method, thereby reducing environmental pollution.

이러한, 폐수의 정화를 위한 장치는 도 1에서 도시된 바와 같이, 폐수가 인입되는 유량조정조(100), 상기 유량조정조(100)에서 유입되는 폐수를 유동성 담체를 이용하여 유기물을 걸러내는 복수개의 폭기조(200), 상기 폭기조(200)를 거친 정화수내 유기물을 침전 정화시키는 침전조(300), 상기 침전조(300)를 거친 정화수를 저자하는 저장조(400)로 구성된다.As shown in FIG. 1, the apparatus for purifying wastewater includes a flow rate adjusting tank 100 in which wastewater is introduced, a plurality of aeration tanks 100 for filtering the organic wastes introduced from the flow rate adjusting tank 100 using a fluid carrier, A sedimentation tank 300 for sedimenting and purifying organic matters in the purified water through the aeration tank 200 and a reservoir 400 for purifying purified water through the sedimentation tank 300.

그러나, 종래의 폐수정화장치에 있어서 폭기조(200)에서 인접한 폭기조(200)나 침전조(300)로의 이송시 폐수가 복수개의 관통공이 형성된 벽면스크린(210)을 통해 이송됨으로써 오래시간 사용시 벽면스크린(210)에 유동성 담체가 부착되는 문제가 발생된다.However, in the conventional wastewater purification apparatus, wastewater is transferred through the wall surface screen 210 having a plurality of through holes when the wastewater is transferred from the aeration tank 200 to the adjacent aeration tank 200 or the settling tank 300, A problem arises in that the fluid carrier is attached.

즉, 폭기조의 유동성 담체와 폐수내 유기물이 유속으로 인한 흐름에 의해 일측의 폭기조에 설치된 벽면스크린에 부착되면서 관통공을 막게 되어 폐수의 흐름을 방해하여 소정 정화시간이후로는 폐수가 역류하는 문제점이 있다.That is, the fluid carrier of the aeration tank and the organic matter in the wastewater are attached to the wall surface screen installed in the aeration tank at one side by the flow due to the flow rate, thereby blocking the flow of the wastewater, thereby causing the wastewater to flow backward after a predetermined purification time have.
