The process of detaching by 22) and falling to the collection tank 23 is performed continuously.

상기와 같은 과정을 통해 부유물이 걸러진 처리수에는 수면으로 부상하지 못한 미세한 부유물을 함유하고 있고, 이 부유물에 의해 처리수의 혼탁도가 결정되는 것으로, 실시예에서는 수중에 부유물이 함유된 처리수를 여과하기 위한 타워식 여과조(24)를 개시하고 있다.The treated water filtered through the above-described process contains fine suspended solids that do not float to the surface, and the turbidity of the treated water is determined by the suspended solids. In the embodiment, the treated water containing the suspended solids is A tower filtration tank 24 for filtration is disclosed.

실시예에 따른 여과조(24)는 하부가 격자형태의 받침대를 갖고, 상부가 개방된 형태의 단위여과조(25)를 적층시킨 단위그룹을 형성하고 있다. 이 여과조 단위그룹은 부상조(10) 측벽에서 외향으로 연장된 브래킷(26) 상면에 안치되는 것으로,실시예에서는 도면과 같이 수직으로 3개 내지 4개의 단위여과조(25)를 적층시킴과 동시에 측방에도 단위여과조(25)를 나란하게 배열하고 있다.The filtration tank 24 according to the embodiment forms a unit group in which the lower portion has a lattice-shaped pedestal and the upper portion of the filtration tank 25 is stacked. The filtration unit unit group is placed on the upper surface of the bracket 26 extending outwardly from the side wall of the floating tank 10. In the embodiment, as shown in the figure, the three to four unit filtration tanks 25 are vertically stacked and at the same time. Edo unit filtration tanks 25 are arranged side by side.

상기 여과조(24)에 있어서, 각각의 단위여과조(25)는 바닥면에 여과포(25a)를 깔고 그 상면에 상부로부터 굵은 모래(25b), 가는 모래(25c), 활성탄이 포함된 토양(25d)을 순차적으로 적층시켜 처리수를 토과시키는 과정을 통해 부유물을 제거시킨다.In the filtration tank 24, each unit filtration tank 25 is laid with a filter cloth (25a) on the bottom surface and coarse sand (25b), fine sand (25c) from the top on the top surface 25d of soil containing activated carbon By sequentially stacking to remove the float through the process of over-treating the treated water.

이 여과조 단위그룹은 상방이나 또는 하방에 위치한 다른 단위그룹과 함께 하나의 시스템을 형성하고 있으며, 단위그룹의 사이에는 일정한 간격을 유지시키는 것에 의해 공기와 접촉할 수 있도록 함으로써 산소농도 요구량을 만족시킬 수 있는 효과를 얻을 수 있다.The filter tank unit group forms a system together with other unit groups located above or below, and it is possible to meet the oxygen concentration requirements by allowing contact with air by maintaining a constant interval between the unit groups. You can get the effect.

이렇게 설치된 여과조(24)에는 처리수 이송수단에 의해 부상조(10)에서 펌핑된 처리수를 상방에서 낙하시키게 되며, 낙하된 처리수는 상기 여과조(24)를 순차적으로 통과하면서 부유물이 여과된 상태의 맑고 깨끗한 처리수로 재생되는 것이다.In this way, the treated water pumped from the floating tank 10 is dropped from above by the treated water transporting means in the installed filtration tank 24, and the dropped treated water passes through the filtration tank 24 sequentially while the suspended matter is filtered. Will be regenerated with clean and clean water.

실시예에서 개시하고 있는 여과조(24)는 종래 여과조를 축조하기 위해 필요로 했던 넓은 면적을 생략할 수 있고, 더욱이 단위여과조들이 타워식으로 적층되어 있기 때문에 오염된 여과조를 쉽게 교체할 수 있는 장점이 있다.The filtration tank 24 disclosed in the embodiment can omit the large area required to build the conventional filtration tank, and furthermore, since the unit filtration tanks are stacked in a tower type, the contaminated filtration tank can be easily replaced. have.

상기 처리수 이송수단은 도시되지 않은 펌프를 분배파이프(27)의 관로상에 설치하고, 이 분배파이프(27)를 통해 부상조(10)와 여과조(24)를 연결시키는 처리수 유동경로를 이루게 되며, 도시되지 않은 제어수단에 의해 상기 펌프를 제어하는것에 의해 수면으로 부상한 부유물을 걸러낸 후 부상조(10)에 저장된 처리수를 펌핑하여 상기 여과조(24)로 이송시켜 낙하시키게 된다.The treatment water conveying means is provided with a pump (not shown) on the conduit of the distribution pipe 27 to form a treatment water flow path connecting the floating tank 10 and the filtration tank 24 through the distribution pipe 27. By filtering the pump by the control means (not shown), the float floating on the water surface is filtered, and then the treated water stored in the floating tank 10 is pumped to the filtration tank 24 to be dropped.

상기 파이프(27)는 입구측이 부상조(10)에 저장된 처리수의 수중에 위치하도록 함으로써 수면으로 부상된 부유물이 유동되지 않도록 하고 있으며, 출구측은 그 단부에 노즐(28)을 설치함으로써 단위여과조(24)에 고르게 분포시켜 여과조(24) 전면적에 걸쳐 투과될 수 있도록 하는 것에 의해 여과효과를 배가시키고 있다.The pipe 27 has an inlet side located in the water of the treated water stored in the floatation tank 10 to prevent floating floated on the water surface, and the outlet side has a unit filtration tank by installing a nozzle 28 at the end thereof. The filtration effect is doubled by distributing it evenly over 24 so that it can permeate over the entire area of the filtration tank 24.

이상 실시예에서와 같이 본 발명은 부상조의 수면으로 부상한 부유물을 걸러낸 처리수를 여과시킴으로써 여과효과를 배가시킬 수 있고, 더욱이 부상조의 측벽에 단위여과조를 조합한 여과조 그룹을 직하방으로 배열하는 것에 의해 종래 여과조를 축조하기 위한 많은 면적을 필요로 하지 않은 최적화가 가능할 뿐만 아니라 오염된 단위여과조를 쉽게 교체할 수 있는 등 시설물 관리가 편리하다.As in the above embodiment, the present invention can double the filtration effect by filtering the treated water filtering out the floating matters floating on the surface of the floating tank, and further, the filter tank group combining the unit filtration tank on the side wall of the floating tank is arranged directly below. This enables convenient management of facilities such as not only optimizing not requiring a large area for building conventional filtration tanks but also easily replacing contaminated unit filtration tanks.
