Description

상,하수처리장의 침전지용 정류벽{Partition Wall for Water Treatment Tank}Partition Wall for Water Treatment Tank in Water and Sewage Treatment Plant

본발명은 상,하수처리장의 침전지 내부에 유입수의 흐름방향에 대하여 직각으로 설치되어서 유입수를 균등하고 완만하게 통수시켜 주는 상,하수처리장의 침전지용 정류벽에 관한 것이다.The present invention relates to a rectifying wall for sedimentation basins in water and sewage treatment plants installed at right angles to the flow direction of the inflow of water in the sedimentation basins of water and sewage treatment plants.

통상적으로 상,하수처리장에는 유입수에 포함되어 있는 플럭(탁질물질)을 침전시키기 위한 침전지를 갖추고 있으며, 이러한 침전지에는 불규칙한 난류의 흐름상태를 보이는 유입수를 균등하게 통수시켜서 그 유입수에 포함되어 있는 플럭의 침전작용을 상승시켜 주도록 정류벽을 설치하여 왔다.Normally, water and sewage treatment plants have a sedimentation basin for sedimentation of flocs (sustained matter) contained in inflow water, and these sedimentation basins have an equal flow of inflow water showing irregular turbulent flow conditions, Rectification walls have been installed to increase the settling action.

이전에는 상기한 바와 같은 상,하수처리장의 침전지용 정류벽을 목재 또는 콘크리트로서 설치하여 왔으나, 이와 같은 목재 정류벽이나 콘크리트 정류벽은 내식성이 취약한 재질적인 특성을 가지기 때문에, 항시 접촉하게 되는 유입수에 의하여 쉽게 부식되어서 수명이 단축되는 문제점이 있었다.Previously, the rectifying walls for sedimentation basins of water and sewage treatment plants as described above have been installed as wood or concrete, but such wooden rectifying walls and concrete rectifying walls have material characteristics that are poor in corrosion resistance, so they are always in contact with influent. There was a problem that the life is reduced by easily corroded by.

더욱이, 콘크리트 정류벽의 경우에는 거푸집을 조립하고 현장콘크리트를 타설한 후에 다시 거푸집을 해체하여야 하는 번거롭고도 까다로운 작업공정을 수행하여서 설치하게 되므로, 상,하수처리장의 침전지 내에 콘크리트 정류벽을 설치하는 데 공사기간 및 공사비용이 과도하게 소요되는 문제점이 있었다.In addition, in the case of concrete rectifying wall, since it is installed by assembling the formwork and placing the site concrete, it is installed by performing a cumbersome and difficult work process of dismantling the formwork again. There was a problem that the construction period and the construction cost is excessively required.

한편, 본 출원인은 상,하수처리장의 침전지용 정류벽과 관련하여 1999년 10월 2일자로 특허출원 제42515호로서 "상,하수처리장의 간벽설치구조 및 그의 시공방법"을 선출원한 사실이 있다.On the other hand, the present applicant has filed a patent application No. 4515 dated October 2, 1999 regarding the sedimentation rectification wall of the water and sewage treatment plant, and the application of the "inter wall installation structure and construction method of the water and sewage treatment plant". .

이 상,하수처리장의 간벽설치구조에 의하면, 유입수가 이동하는 경로 상의 해당위치에 격자형으로 조립되는 고정틀 내에 원통형의 통수공들이 뚫어져서 통수가능하도록 형성된 합성수지 중공판넬들을 설치하여서 구성되도록 함으로써, 간벽을 조립식으로 용이하게 설치하여 불필요한 공사기간 및 공사비용을 감축시켜 줄 뿐만 아니라, 설치된 간벽의 내구성을 증대시켜서 사용수명을 연장시켜 주는 등의 장점을 가지게 되었다.According to the partition wall installation structure of the water and sewage treatment plant, the hollow wall is formed by installing synthetic hollow hollow panels formed through the cylindrical through holes in a fixed frame assembled in a lattice shape at a corresponding position on the inflow path. It can be easily installed in a prefabricated manner, reducing unnecessary construction periods and construction costs, and increasing the durability of the installed wall, thereby extending its service life.

그러나, 이와 같은 상,하수처리장의 간벽은 합성수지 중공판넬에 원통형의 통수공들을 뚫어서 유입수를 통수시켜 주도록 설치되기 때문에, 통수공을 통과한 유입수가 급속히 유출되어서 그 유입수에 포함된 플록의 침전효율을 저하시키는 경향이 있었다.However, since the partition wall of the water and sewage treatment plant is installed to allow the inflow of water through the cylindrical hollow holes in the synthetic resin hollow panel, the inflow water passing through the water holes rapidly flows out, thereby increasing the flocculation efficiency of the flocs contained in the inflow water. There was a tendency to decrease.

이를 좀더 구체적으로 설명하면, 상,하수처리장의 간벽에 천공되어 있는 통수공은 입구측과 출구측이 동일한 직경크기를 가지는 원통형으로 뚫어져서 형성되어 있기 때문에, 통수공의 입구측으로 인입되려는 유입수의 유속이 급속히 빨라지게 되고, 일단 유속이 빨라진 유입수는 통수공의 출구측을 통하여 급속히 유출된다. 이와 같이 통수공을 통하여 급속히 유출되는 유입수는 그 유입수에 포함되어 있는 플록의 침전작용을 지체시켜서, 상,하수처리장의 침전지 내에서 플록의 침전효율을 저하시키는 원인을 제공하게 되었다.In more detail, the water flow holes drilled in the liver walls of the upper and the sewage treatment plants are formed by being formed in a cylindrical shape having the same diameter size at the inlet side and the outlet side, so that the flow rate of the inflow water to be drawn into the inlet side of the water hole is This rapid speed is increased, and once the flow velocity is increased, the influent flows out rapidly through the outlet side of the water hole. As such, the inflow water flowing out through the water hole retards the flocculation of the flocs contained in the inflow water, thereby providing a cause of lowering flocculation efficiency in the sedimentation basin of the water and sewage treatment plant.

본발명은 정류벽을 이루는 합성수지 중공판넬에 유입수를 완만하게 유출시켜 주도록 통수공을 형성하여서, 상,하수처리장의 침전지에서 유입수에 포함된 플록의 침전효율을 극대화하여 주는 상,하수처리장의 침전지용 정류벽을 제공하는 데 그 목적이 있다.The present invention forms a through hole to gently inflow the inflow water into the synthetic resin hollow panel forming a rectifying wall, to maximize the sedimentation efficiency of flocs contained in the influent in the sedimentation basin of the water and sewage treatment plant The purpose is to provide a rectifying wall.

It is characterized by technical construction.

다시말해서, 본발명의 상,하수처리장의 침전지용 정류벽(1)은 도2의 도시와 같이, 합성수지 중공판넬(10)에 깔대기형의 구멍(21)을 뚫고, 그 깔대기형의 구멍(21) 내면에 삽입관(22)을 부설하여 유입수에 대한 입구측의 인입단면은 작고 출구측의 유출단면이 큰 통수공(20)들을 형성하여서, 상기 통수공(20)들로서 유입수를 완만하게 유출시켜 주도록 정류벽(1)을 구성함으로써, 유입수에 포함되어 있는 플록의 침전작용 시기를 앞당겨주어서, 상,하수처리장의 침전지(2)의 침전효율을 획기적으로 향상시켜 주는 장점을 가지게 되는 것이다.In other words, the rectifying wall 1 for the sedimentation basin 1 of the water and sewage treatment plant of the present invention drills the funnel-shaped hole 21 in the synthetic resin hollow panel 10, as shown in Fig. 2, and the funnel-shaped hole 21 ) Inserting the insertion pipe 22 on the inner surface of the inlet section for the inlet to the inlet is small and the outlet side of the outlet to form a large through-holes 20, the inlet water gently flowing out as the through-holes 20 By constructing the rectifying wall (1) to give the time to precipitate the floc included in the influent, it has the advantage of significantly improving the settling efficiency of the sedimentation basin (2) of the water and sewage treatment plant.

이하, 첨부도면에 도시되는 구체적인 실시예를 통하여 본발명의 기술내용을 상세히 설명하면 다음과 같다.Hereinafter, the technical details of the present invention through the specific embodiments shown in the accompanying drawings in detail as follows.

본발명의 실시예에서 정류벽(1)은 침전지(2) 내면의 해당위치에 하부 및 중간 수평부재(31)(32)와 양측의 수직부재(33)들을 연결하여서 상하방향으로 조립공간이 확보되도록 고정틀(30)을 설치하고, 상기 고정틀(30) 내의 조립공간에 통수공(20)들이 형성된 합성수지 중공판넬(10)들을 설치하여서 된 것으로 예시하고 있다.In the embodiment of the present invention, the rectifying wall 1 connects the lower and middle horizontal members 31 and 32 and the vertical members 33 on both sides to the corresponding positions on the inner surface of the sedimentation basin 2 to secure the assembly space in the vertical direction. The fixing frame 30 is installed as much as possible, and the synthetic resin hollow panels 10 in which the water holes 20 are formed in the assembly space in the fixing frame 30 are illustrated.

상기 합성수지 중공판넬(10)은 각각 굴곡되는 파형이 폭방향으로 반복되는 굴곡판부(11)의 양측면에 일체로서 평활하게 접합되는 양측의 평판부(12)로 이루어져서, 그 굴곡판부(11)와 양측의 평판부(12) 내에 중공부(13)들이 배열 형성되도록 만들어서 된다. 이러한 합성수지 중공판넬(10)은 내식성이 우수한 합성수지를 소재로하여서 만들어지기 때문에, 유입수와 항시 접촉하더라도 부식됨을 방지하여서 정류벽(1)의 사용수명을 연장시켜 주는 부수적인 이점을 기대할 수 있게 되는 것이다.The synthetic resin hollow panel 10 consists of flat plate portions 12 on both sides that are integrally and smoothly joined to both side surfaces of the curved plate portion 11 in which the curved waveform is repeated in the width direction, respectively, and the curved plate portion 11 and both sides thereof. The hollow portions 13 are arranged to be formed in the flat plate portion 12 of the. Since the synthetic resin hollow panel 10 is made of a synthetic resin having excellent corrosion resistance, it is possible to expect a secondary advantage of extending the service life of the rectifying wall 1 by preventing corrosion even when in contact with the influent at all times. .

그리고, 상기 합성수지 중공판넬(10)에 형성되는 통수공(20)은 각각 유입수가 인입되는 입구측의 직경이 작고 유입수가 유출되는 출구측의 직경이 상대적으로 크게 뚫어진 깔대기형의 구멍(21)의 내면에, 그 깔대기형의 구멍과 상응하는 단면형상을 가지는 삽입관(22)을 접합시켜서 일체로 부설되도록 함이 중요하다. 그 이유는, 통수공(20)의 입구측으로부터 유입수가 빠르게 인입되더라도 통수공(20)의 출구측을 통하여 완만하게 유출되도록 하여서, 유입수에 포함되어 있는 플록의 침전작용을 조기에 일으킬 수 있도록 하기 위함이다.And, the through-hole 20 formed in the synthetic resin hollow panel 10 has a small diameter of the inlet side through which the inlet water is introduced, respectively, of the funnel-shaped hole 21 in which the diameter of the outlet side through which the inflow water is discharged is relatively large. On the inner surface, it is important to join the insertion tube 22 having the cross-sectional shape corresponding to the funnel-shaped hole so as to be integrally laid. The reason is that, even if the inflow of water from the inlet side of the inlet 20 quickly flows in through the outlet side of the inlet 20, so that the flocculation in the inlet can be precipitated early For sake.

여기에서, 상기 통수공(20)은 그 깔대기형의 구멍(21) 내면에 삽입관(22)을 용접하여서 접합시킬 수도 있으며, 필요에 따라서는 깔대기형의 구멍(21) 내면에 삽입관(22)을 접착제로서 접합시킬 수도 있음을 밝혀 둔다.Here, the water hole 20 may be joined by welding the insertion tube 22 to the inner surface of the funnel-shaped hole 21, if necessary, the insertion tube 22 to the inner surface of the funnel-shaped hole 21. ) May be bonded as an adhesive.

이상에서 살펴 본 바와 같이, 본발명은 정류벽을 이루는 합성수지 중공판넬에 유입수를 완만하게 유출시켜 주도록 통수공을 형성하여서, 상,하수처리장의 침전지에서 유입수에 포함된 플록의 침전효율을 향상시켜 주는 유용한 효과를 가지게 되는 것이다.As described above, the present invention forms a through-hole so as to gently inflow the inflow water in the synthetic resin hollow panel forming a rectifying wall, thereby improving the sedimentation efficiency of the floc contained in the inflow water in the sedimentation basins of water and sewage treatment plants It will have a useful effect.
