Description
본 발명은 상향류식 여과장치이 여재교체시스템에 관한 것이다. The present invention relates to a filter medium replacement system for an upflow filtration device.
각종 생활하수, 산업폐수 등(이하, "폐수"로 통칭함)에는 액체성, 고체성, 기체성의 폐기물이 혼입되어 있다. 일반적으로 생활하수에는 유기물, 부유물질, 질소, 인 등이 함유될 수 있으며, 산업폐수에는 이에 유독성 유기물, 중금속 등의 유해물질이 추가될 수 있다.Various domestic sewage, industrial wastewater, etc. (hereinafter collectively referred to as “wastewater”) contain liquid, solid, and gaseous wastes. In general, domestic sewage may contain organic matter, suspended solids, nitrogen, phosphorus, etc., and industrial wastewater may contain harmful substances such as toxic organic matter and heavy metals.
이에 따라, 폐수는 소정의 처리과정을 거쳐 방류되고 있다. 처리방법은 크게 물리적, 화학적, 생물학적 처리방법 등으로 분류될 수 있다.Accordingly, wastewater is discharged after undergoing a predetermined treatment process. Treatment methods can be broadly classified into physical, chemical, and biological treatment methods.
물리적 처리방법은 스크린(screen), 침강분리(clarifier), 부상분리(flotation tank), 부유물의 고도처리를 위한 여과방법 등이 있고, 주로 비용해성 물질을 분리하는데 사용될 수 있다.Physical treatment methods include screens, clarifiers, flotation tanks, and filtration methods for advanced treatment of suspended matter, and can be mainly used to separate insoluble substances.
화학적 처리방법은 중화(neutralization), 응집-침전 (coagulation & sedimentation), 산화-환원 (oxidation & reduction), 흡착 (adsorption) 등이 있다. 화학적 처리방법은 물리적 또는 생물학적 처리방법을 보완하는 방법으로, 주로 유기물의 농도를 낮춰 방류하거나, 후공정인 생물학적 처리의 전처리 공정으로 사용될 수 있다.Chemical treatment methods include neutralization, coagulation & sedimentation, oxidation & reduction, and adsorption. Chemical treatment methods are complementary to physical or biological treatment methods, and can mainly be used to lower the concentration of organic substances before discharging them or as a pre-treatment process for biological treatment, which is a post-process.
생물학적 처리방법은 폐수 중에 존재하는 유기물 중 생물에 의해 분해 가능한 유기물을 미생물을 이용해 제거하는 방법이다. 생물학적 처리방법은 크게 호기성 처리(aerobic treatment)와 혐기성 처리(anaerobic treatment)로 분류될 수 있다. 호기성 처리에는 활성슬러지법(activated sludge process), 장기폭기법(extended aeration), 산화구법(oxidation ditch), 살수여상법(trickling filter) 등이 있다. 혐기성 처리는 폐수에 농축된 고농도 유기물의 안정화에 주로 사용될 수 있다. 혐기성 저리는 복수 그룹의 미생물이 참여하여 유기물을 메탄가스, 이산화탄소 등의 기체와 최종 안정된 생성물로 분해하는 복합적인 생화학 공정으로 구성될 수 있다.Biological treatment is a method of removing organic substances that can be decomposed by living organisms among the organic substances present in wastewater using microorganisms. Biological treatment methods can be broadly classified into aerobic treatment and anaerobic treatment. Aerobic treatment includes activated sludge process, extended aeration, oxidation ditch, and trickling filter. Anaerobic treatment can be mainly used to stabilize high concentrations of organic matter concentrated in wastewater. Anaerobic frosting can be comprised of a complex biochemical process in which multiple groups of microorganisms participate to decompose organic matter into gases such as methane gas and carbon dioxide and final stable products.
이와 같이 대부분의 폐수처리시스템은 상기와 같은 물리적, 화학적, 생물학적 처리방법 등을 적절히 혼용하여 폐수를 정화 처리하고 있다.As such, most wastewater treatment systems purify wastewater by appropriately combining the above physical, chemical, and biological treatment methods.

The filtration tank 110 may generally have a cylindrical shape extending up and down, and an inclined surface 111 may be formed at the bottom of the filtration tank 110 in the form of an upper-lower narrowing.
여과조(110) 내부에는 여재층(112)이 구비될 수 있다. 여재층(112)은 원수(P1)로부터 불용성 고형물(SuspendedSolid; SS) 등을 여과할 수 있다. 원수(P1)는 여재층(112)을 거쳐 상향 유동될 수 있고, 이 과정에서 원수(P1)에 함유된 불용성 고형물 등이 여재층(112)에 포집될 수 있다. 참고로, 불용성 고형물은 원수(P1)에 입자상으로 부유 내지 분산되어 있는 고형물로서, 부유물, 현탁물 등을 포함할 수 있다.A filter media layer 112 may be provided inside the filtration tank 110. The filter layer 112 can filter insoluble solids (SuspendedSolid; SS), etc. from the raw water (P1). The raw water (P1) may flow upward through the filter layer 112, and in this process, insoluble solids contained in the raw water (P1) may be collected in the filter layer 112. For reference, insoluble solids are solids suspended or dispersed in the form of particles in the raw water (P1) and may include suspended matter, suspension, etc.
여재층(112)은 여과조(110) 하부로부터 소정 높이로 형성될 수 있다. 여재층(112)은 대체로 여과조(110) 높이의 60~80%로 형성될 수 있다.The filter media layer 112 may be formed at a predetermined height from the bottom of the filtration tank 110. The filter media layer 112 may be generally formed to be 60 to 80% of the height of the filter tank 110.

에어리프트관(150)은 여과조(110)의 내부 중앙에서 상하로 연장 형성될 수 있다. 에어리프트관(150) 하단은 대체로 여재층(112)의 하부 영역에 대응되도록 배치될 수 있고, 에어리프트관(150) 상단은 대체로 처리수층(114)의 상부 영역에 대응되도록 배치될 수 있다.The air lift pipe 150 may extend upward and downward from the inner center of the filtration tank 110. The lower end of the air lift pipe 150 may be arranged to generally correspond to the lower area of the filter media layer 112, and the upper end of the air lift pipe 150 may be arranged to generally correspond to the upper area of the treated water layer 114.
에어리프트관(150)은 상하 방향의 유로를 형성할 수 있다. 에어리프트관(150)은 하단으로 여재(113)를 흡입하고, 흡입된 여재(113)를 상부로 이송할 수 있다. 에어리프트관(150)은 외부의 압축기로부터 압축공기를 제공받을 수 있고, 여재(113) 이송은 이러한 압축공기에 의해 이뤄질 수 있다. 한편, 에어리프트관(150)을 통해 이송된 여재(113)는 후술할 역세수챔버(160) 및 세정부(170)를 거쳐 다시 여재층(112) 상부로 공급될 수 있다.The air lift pipe 150 may form a flow path in the vertical direction. The air lift pipe 150 can suck the filter medium 113 to the bottom and transfer the sucked filter medium 113 to the top. The air lift pipe 150 can receive compressed air from an external compressor, and the filter medium 113 can be transported by this compressed air. Meanwhile, the filter medium 113 transferred through the air lift pipe 150 may be supplied to the upper part of the filter medium layer 112 again through the backwash chamber 160 and the washing unit 170, which will be described later.
여재(113)는 에어리프트관(150) 내를 상향 이동되면서, 이에 부착된 불용성 고형물 등의 오염물이 제거될 수 있다. 오염물을 포함한 여재(113)가 에어리프트관(150)을 따라 상향 이동되면서, 이에 포함된 여재(113), 물, 공기 등의 속도차에 의해 여재(113)에 부착된 오염물이 탈리되는 것이다.As the filter medium 113 moves upward within the air lift pipe 150, contaminants such as insoluble solids attached thereto can be removed. As the filter medium 113 containing contaminants moves upward along the air lift pipe 150, the contaminants attached to the filter medium 113 are detached due to the speed difference between the filter medium 113, water, and air contained therein.
한편, 본 실시예의 상향류식 여과기(100)는 역세수챔버(160)를 포함할 수 있다.Meanwhile, the upflow filter 100 of this embodiment may include a backwash chamber 160.
역세수챔버(160)는 에어리프트관(150) 상단에 구비될 수 있다. 역세수챔버(160)는 대체로 처리수층(114)의 상부영역에 배치될 수 있다. 역세수챔버(160)는 에어리프트관(150)을 통해 상향 이동된 역세수(back washing water; S1)를 일시적 저장하고, 외부 배출시킬 수 있다.The backwash chamber 160 may be provided at the top of the air lift pipe 150. The backwash water chamber 160 may be generally disposed in the upper area of the treated water layer 114. The back washing water chamber 160 temporarily stores back washing water (S1) moved upward through the air lift pipe 150 and discharges it to the outside.
역세수챔버(160) 일측에는 역세수배출관(161)이 구비될 수 있다. 역세수배출관(161)은 역세수챔버(160)로 제공된 역세수(S1)를 외부 배출시킬 수 있다. 또한, 역세수챔버(160)는 역세수웨어(162)를 구비할 수 있다. 역세수챔버(160)로 제공된 역세수(S1)는 역세수웨어(162)를 월류하여 역세수배출관(161)으로 유동될 수 있다. 역세수 배출관(161)을 통해 배출된 역세수(S1)는 슬러지저류조(21, 도 1 참조) 등으로 제공될 수 있다. 다만, 본 실시예에 있어서, 배출된 역세수(S1)의 후속 처리는 특별히 제한되지 않는다.A backwash water discharge pipe 161 may be provided on one side of the backwash water chamber 160. The backwash water discharge pipe 161 can discharge the backwash water (S1) provided to the backwash water chamber 160 to the outside. Additionally, the backwash water chamber 160 may be provided with backwash wear 162. The backwash water (S1) provided to the backwash water chamber 160 may overflow the backwash water ware 162 and flow into the backwash water discharge pipe 161. The backwash water (S1) discharged through the backwash water discharge pipe 161 may be provided to the sludge storage tank 21 (see FIG. 1). However, in this embodiment, the subsequent treatment of the discharged backwash water (S1) is not particularly limited.
