Description
본 고안은 미생물 접촉과 식물을 이용한 하수, 하천수 및 오·폐수의 처리시스템에 관한 것으로, 더욱 상세하게는 본 고안은 인공습지에서 생물학적 처리법에 의한 습지 내 유기물 및 질소, 인 등의 영양물질을 효과적으로 제거하는 생물학적처리시스템에 관한 것이다.The present invention relates to a treatment system for sewage, river water and wastewater using microbial contact and plants, and more specifically, the present invention effectively treats nutrients such as nitrogen, phosphorus and organic substances in wetlands by biological treatment methods in artificial wetlands. To a biological treatment system for removal.
종래에는 도1a에서 도시한 바와 같은 모래층 단독 또는 모래층과 자갈층 복합으로 구성된 여과층(A)을 형성하고 여과층(메디아층)상부에 수생식물을 식재하여 식물을 이용한 오·폐수 처리방법이 사용되어 왔다.Conventionally, a wastewater treatment method using plants is formed by forming a filtration layer A composed of a sand layer alone or a sand layer and a gravel layer composite as shown in FIG. 1A, and planting aquatic plants on the filtration layer (media layer). come.
한편 도1b에서 도시한 바와 같이 오·폐수를 정화하기 위하여 인공습지 끝부분에 별도의 집수정(6) 형태의 침전지를 형성하고 수중펌프에 의하여 정화된 물을 인공습지의 저류시설로 순환수관을 통해 환류재순환시킨 다음 재차 정화시킨 후 동일한 수중펌프로써 퍼올려 방류수관을 통해 수로로 방류시키는 오·폐수 처리방법이 공지된 바 있다.Meanwhile, as illustrated in FIG. 1B, a sewage pond in the form of a separate sump (6) is formed at the end of the artificial wetland to purify the wastewater, and the water purified by the water pump is circulated to the storage facility of the artificial wetland. It has been known that the wastewater treatment method is to recycle the reflux through and then purify it again and then pump it up with the same submersible pump to discharge the water through the discharge pipe.
그러나 전자와 같은 종래기술은 단지 인공습지의 여과층(A)상부에 식재된 수생식물(3)의 접촉에 의하여만 오·폐수의 유기물이 분해되고 여과층이 모래로만 구성되어 있어서 미생물 접촉에 의한 유기물 분해속도가 느릴뿐만 아니라 일단 미생물 성장이 과도하게 되고 유입수의 SS결합물질이 많게 되면 시간이 경과되면서 상기 모래로만 된 여과층(A)의 공극이 폐색되어 습지의 정화효과가 크게 떨어지는 단점이 있었으며, 후자와 같이 공지된 기술은 여과층(A)상부에 식재된 수생식물(3)에 의하여 유기물분해가 촉진되어 상기 여과재층 상하부에 입자가 작은 모래와 입자가 큰 자갈로 구성되어 공극이 큰 여과층(A)에 의하여 부유입자의 막힘현상이 적고 여과속도가 빨라져 미생물의 활동과 서식이 증대됨으로써 오·폐수의 정화작용이 상당기간 지연될 뿐만 아니라 상당한 효과가 있는 것은 사실이지만 이 역시 별도로 설치한 집수정의 침전지에는 부유물질이 침전되어 퇴적토가 형성되므로서 일정 기간마다 침전퇴적물을 준설하여야 하는 단점이 있고, 특히 이와같은 준설작업은 인공습지 저류시설 내에 있는 물을 완전히 배수시킨다음 실시해야 하며, 저류 인공습지의 물을 인공적으로 배수할 때는 별도로 설치한 순환펌프로 양수하거나 하천으로 자연 유하가 가능한 지역에서는 별도의 자연 유하관로와 수문을 설치하여야 그 배수가 가능하다고 하는 문제점이 있었다.However, in the prior art such as the former, organic matters of wastewater and wastewater are decomposed only by the contact of the aquatic plants 3 planted on the filtration layer (A) of artificial wetland, and the filtration layer is composed of sand, which is caused by microbial contact. Not only was the organic decomposition rate slow but also the microbial growth was excessive and the amount of SS binding material in the influent increased. As time passed, the pores of the sand-only filtration layer (A) were occluded, which greatly reduced the purification effect of the wetland. In the latter known technique, organic decomposition is promoted by the aquatic plant 3 planted on the filter layer A, and the upper and lower portions of the filter material layer are composed of small particles of sand and large particles of gravel. Due to the layer (A), there is less clogging of suspended particles and a faster filtration rate, which increases the activity and habitat of microorganisms, which only delays the purification of wastewater. In addition, it is true that there is a significant effect, but this also has the disadvantage that the sedimentary sediment is to be dredged at a certain period of time because the sediment is formed due to the sedimentation of suspended solids in the sedimentation basin of the sewage well installed separately, especially such dredging storage After draining the water in the facility completely, it should be carried out. When artificially draining water from the reservoir artificial wetland, the pump should be pumped with a separate circulation pump, or a separate natural drainage pipe and a sluice gate should be installed in an area where natural flow into the river is possible. There was a problem that the drainage was possible.
그 뿐만 아니라, 상기 공지된 문헌들에 의하면 주기적인 자연유하에 의한 수인공습지의 정화된 물을 인공적으로 양수펌프를 사용하여 양수하거나 수문을 열고 자연유하시키려면 그 만큼 별도의 시설이 필요하고 노동력이 소요될 뿐만 아니라 인위적인 양수과정과 자연유하에 의해 하천으로 방류하는 과정에서 필연적으로 오·폐수와 준설토가 방류되어 하수, 하천수를 재오염시킬 수 밖에 없다고 하는 문제점이 있으며 양수 또는 유하과정에서 인공습지에 식재된 수생식물의 근권부에 부착된 잔모래 등이 함께 소실되어 양수 또는 유하 후에 식생이 불량하게 되므로서 인공습지의 오·폐수 정화능력이 현저히 떨어지는 문제점이 있었다.In addition, according to the above-mentioned documents, it is necessary to separate water and labor by artificially pumping the purified water of the wetland wetlands by using natural pumping pumps or opening the floodgates and draining them naturally. In addition, the wastewater and dredged soil are inevitably discharged into the river due to artificial pumping process and natural sewage, which inevitably leads to recontamination of sewage and river water. Residual sands, etc. attached to the root zone of the planted aquatic plants are lost together, resulting in poor vegetation after pumping or dripping, resulting in a significant drop in the ability to purify sewage and wastewater in artificial wetlands.
또, 상기 공지기술에 따르면 여과층(A)의 상부에서 하부로 오·폐수가 이동하는 과정에서 유기물이나 질소 및 인화합물이 식물 및 미생물에 접촉·분해되어 정화되기는 하나 오·폐수의 정화효과가 장기적인 면에서 불량하고 따라서 순환펌프로 강제 양수하거나 별도의 수중펌프로 강제 환류시키는 방법을 도입할 수 밖에 없었다.In addition, according to the known art, organic matter, nitrogen, and phosphorus compounds are contacted and decomposed to plants and microorganisms in the process of moving the wastewater from the upper part to the lower part of the filter layer A, but the purification effect of the wastewater is reduced. It was poor in the long term and therefore forced to pump with a circulation pump or forced to reflux with a separate submersible pump.
본 고안은 상기 종래기술 또는 공지기술의 제단점과 결함을 감안하여 보완함으로써 신규하고도 진보성이 구유된 하수, 하천수 및 오·폐수 정화시스템을 제공함을 그 목적으로 한다.The object of the present invention is to provide a sewage, river water and waste water purification system that is new and progressively maneuvered by supplementing in view of the disadvantages and deficiencies of the prior art or known technology.
본 고안의 상기 목적은 인공습지에 자갈을 위에서 아래로 작은 자갈에서 큰 자갈순서로 여과재층(A)으로서 메디아층을 형성하고, 상기 여과재층 상부에 천연섬유메트를 포설하여 그 곳에만 수생식물을 식재하도록 하고, 작업통로를 형성하며 상기 여과재층(A)내에는 상하방향으로 일정간격을 두고 다수의 산기유도관을 매설하되 상기 산기유도관내에는 폭기장치를 설치하여 에어를 공급하도록 하고, 상기 여과층 일측에는 오·폐수 유입관을 다른 일측에는 유출관을 수평방향으로 동결수심 이하깊이로 매립하되 유공관으로 형성하여 오·폐수의 유입, 슈출시 물 흐름을 균등하게 하며, 상기 여과층 하부에는 슬러지 인발관을 수평으로 매설하여 정기적 또는 필요시 수시로 슬러지를 인발하도록 하여 미생물 접촉과 수생식물 식생을 유리하게 함으로써 오·폐수에 존재하는 유기물을 비롯하여 질소와 인과 같은 영양물질을 효과적으로 제거하여 자연정화를 극대화함으로써 달성하였다.The object of the present invention is to form a median layer as the filter media layer (A) in the gravel order from the small gravel to the large gravel in artificial wetland, and to install a natural fiber mat on the filter media layer only planting aquatic plants there. And forming a working passage and embedding a plurality of acid induction pipes at a predetermined interval in the vertical direction in the filter medium layer A, but installing an aeration device in the acid induction pipe to supply air, and the filter layer One side of the wastewater inflow pipe and the other side of the outlet pipe in the horizontal direction to be buried below the depth of freezing depth, formed as a perforated pipe to equalize the water flow during inflow and outflow of the wastewater, and sludge withdrawal under the filter layer By laying the pipe horizontally to draw sludge on a regular or occasional basis, which favors microbial contact and aquatic vegetation. Including organic matter present in the waste water was achieved by removing nutrients such as phosphorus and nitrogen efficiently maximize the natural purification.
이하, 본 고안의 구성을 작용효과와 함께 상세히 설명한다.Hereinafter, the configuration of the present invention will be described in detail with the effect.

본 고안은 도 2에 도시한 바와 같이 수생식물과 여과재층과 유입, 유출관과 폭기장치로 구성된 하수, 하천수 및 오·폐수 처리시스템에 있어서,The present invention, as shown in Figure 2 in the sewage, river and sewage treatment system consisting of aquatic plants, filter media layer and inlet, outlet pipe and aeration device,
상기 수생식물(3)이 천연섬유매트(7)에 식재되고 섬유매트와 섬유매트사이에는 작업통로가 구비되며, 상기 여과재층(A)은 위에서 아래까지 작은자갈(12), 중간자갈(9), 큰자갈(2) 순서로 적층 구성되고, 상기 여과재층(A)내에는 상하방향으로 상부와 하부가 개구된 다수의 산기유도관(50)을 매설하되 산기유도관내에는 폭기장치(51)를 설치하며, 한편 상기 여과층의 일측에는 오·폐수 유입관을 다른 일측에는 오·폐수 유출관을 수평방향으로 매립하되 유공관으로 하고 매립깊이는 동결 수심이하에 위치시키며, 상기 여과층 하부에는 슬러지 인발관(10)을 수평방향으로 매설하여 슬러지 배출관(11)과 연통하여서 됨을 특징으로 하는 하수, 하천수 및 오·폐수 처리시스템으로 구성되어 있다.The aquatic plant (3) is planted in a natural fiber mat (7) and is provided with a working passage between the fiber mat and the fiber mat, the filter material layer (A) from the top to the bottom small gravel (12), intermediate gravel (9) In the filter layer (A), a plurality of acid induction pipes 50 having upper and lower openings are buried in the filter material layer A, and the aeration device 51 is disposed in the acid induction pipes. On the other hand, the wastewater inlet pipe on one side of the filtration layer and the wastewater outlet pipe on the other side are buried in the horizontal direction, and the buried depth is located below the freezing depth, and the sludge is drawn out below the filtration layer. It is composed of sewage, river water and waste water treatment system, characterized in that the pipe 10 is embedded in the horizontal direction to communicate with the sludge discharge pipe (11).
인공습지에 있어서 하수, 하천수 또는 방류되는 오·폐수를 정화하기 위하여정화효과가 우수하고 습생식물로서 갈대 등의 수생식물(3)을 종래와 같이 여과재층(A)의 모래위에 직접 식재하지 아니하고 천연섬유 매트(mat)위 상에 식재하여 종래와 같이 모래를 사용하거나 또는 사용하지 않아도 좋으며, 따라서 모래에 의한 인공습지의 여과층(A)이 폐색되지 않도록 하였다. 본 고안에서 사용할 수 있는 천연섬유 매트(7)는 식물체를 지지할 수 있는 것이면 어느 것이라도 좋으나 예컨데 천연섬유 물질로서 코코넛파이버(coconut fiber)가 바람직하다.It is excellent in purifying effect in order to purify sewage, river water or discharged sewage in artificial wetland.
