Description

수처리 시스템{WATER TREATMENT SYSTEM}Water treatment system {WATER TREATMENT SYSTEM}

본 발명은 수처리 시스템에 관한 것이다.The present invention relates to a water treatment system.

일반적으로, 우천시 나무토막이나 비닐 및 도로·노상의 각종 오염물을 포함하는 초기우수(First Flush) 및 합류식 하수 월류수(Combined Sewer Overfiows)가 별도의 여과처리 없이 저류지(貯溜池) 등에 곧바로 유입될 경우 수질을 크게 악화시킬 수 있다.In general, when the rainwater flows directly into the reservoir without first filtering the first flush and combined sewer overfiows, which include various kinds of contaminants on roads or roads and roads, Can greatly deteriorate.

이를 해결하기 위하여 수처리 시스템을 이용하여 초기우수 및 합류식 하수 월류수를 여과처리한 후 방류토록 하고 있으며, 상기 수처리 시스템은 처리형태에 따라 크게 장치형과 식생·저류형으로 구분하고 있다.In order to solve this problem, the initial excellent and combined sewage overflow water is discharged after filtration using a water treatment system. The water treatment system is largely divided into a device type, a vegetation type, and a storage type according to the treatment type.

그러나, 상기 장치형 수처리 시스템은 설치의 곤란함 및 유지관리에 어려움이 있으며, 특히 여과장치의 유지관리가 불량할 경우 여과층 폐색 등에 의한 기능상실우려가 있다.However, the device-type water treatment system has difficulty in installation and difficulty in maintenance, and in particular, when the maintenance of the filtration device is poor, there is a risk of malfunction due to the blockage of the filtration layer.

아울러, 종래의 장치형 수처리 시스템은 저류지에 고농도의 초기우수 및 합류식 하수 월류수가 이미 유입된 후 여과장치를 이용하여 여과처리하고 있어 방대한 양의 여과처리로 인해 처리효율이 상당히 낮다는 문제점이 있다.In addition, the conventional apparatus-type water treatment system has a problem that the treatment efficiency is considerably low due to the vast amount of filtration treatment since the high concentration of the initial good and the combined sewage overflow water is already introduced into the reservoir, and then filtered using a filtration device.

상기 식생·저류형 수처리 시스템은 수초를 이용한 수질정화와 오염물의 자연침전분해 등 자연의 자정능력을 이용하는 방식으로, 이에 따라 자연여건 및 계절적 영향을 크게 받으므로, 안정적 처리효율의 유지에 어려움이 발생하는 문제점이 있다.The vegetation / reservoir type water treatment system utilizes natural self-cleaning ability such as water purification using water plants and natural sedimentation of contaminants. Therefore, it is difficult to maintain stable treatment efficiency because it is greatly affected by natural conditions and seasonal effects. There is a problem.

또한, 장치형 수처리 시스템에 비해 처리효율이 낮을 뿐만 아니라 저류지 바닥에 침전된 오염물질이 부패하거나, 상기 저류지 내 영양염류 과다유입으로 조류발생과 고사로 썩는 문제가 발생하고 있으며, 이로 인해 토양오염 및 악취발생 등 주변환경에 악영향을 미치는 폐단이 있다.In addition, the treatment efficiency is lower than that of the device type water treatment system, and contaminants deposited on the bottom of the reservoir are decayed, or due to excessive inflow of nutrients in the reservoir, problems of rotting due to algae generation and death are caused. There are some disadvantages that adversely affect the surrounding environment such as odor occurrence.

나아가, 장치형 수처리 시스템에 비하여 저류시 부지를 과다하게 필요로 하고 있어 비경제적이며, 유지관리 측면에도 상당한 어려움이 발생하고 있다.In addition, compared to the device type water treatment system, the storage site requires an excessive amount of land, which is uneconomical and causes considerable difficulties in terms of maintenance.

따라서, 본 발명은 종래와 같이 장치형과 식생·저류형을 개별 이용하여 초기우수 및 합류식 하수 월류수를 처리한 후 저류지 등에 방류하는데 따른 문제를 해결하기 위한 것이다.Accordingly, the present invention is to solve the problem of discharged to the reservoir after treating the initial excellent and combined sewage overflow water by using the device type and vegetation, storage type separately as in the prior art.

본 발명의 목적은, 장치형과 식생·저류형의 기능을 상호 보완하여 친환경적으로 처리수를 여과처리할 수 있도록 한 수처리 시스템을 제공하는 데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a water treatment system that makes it possible to filter the treated water in an environmentally friendly manner by complementing the functions of the device type and the vegetation and storage type.

도 4는 본 발명의 설치상태를 평면도로 보인 것으로, 유입맨홀, 여과시설물 및 식생저류부가 서로 연계되어 방류수역 및 인근 지면에 매립된 것을 보이고 있다.4 is a plan view showing the installation of the present invention, showing that the inlet manhole, the filtering facility and the vegetation reservoir are buried in the discharge water and the adjacent ground.

즉, 본 발명은 장치형과 식생·저류형의 기능을 상호 보완하여 친환경적으로 처리수를 여과처리한 후 이를 방류수역(1)에 방류할 수 있도록 유입맨홀(10), 스크린장치(30), 여과장치(31) 및 식생저류부(40)를 포함하는 것을 그 기술적 구성상의 기본 특징으로 한다.That is, the present invention complements the functions of the device type and the vegetation and storage type to filter the treated water in an environmentally friendly manner and then discharge it into the discharge water (1), the inlet manhole (10), the screen device (30), Including the filtration device 31 and the vegetation reservoir 40 is a basic feature of the technical configuration.

여기서, 상기 방류수역(1)은 저류지(貯溜池), 자연하천 및 인근해역을 포함하는 포괄적 의미로 해석되어야 한다, 또한 처리수는 초기우수(First Flush) 및 합류식 하수 월류수(Combined Sewer Overfiows)를 포함한 포괄적 의미로 해석되어야 한다.Here, the discharge water (1) is to be interpreted in a comprehensive sense including the reservoir, natural rivers and nearby waters, and the treated water is defined as the First Flush and Combined Sewer Overfiows. It should be interpreted in a comprehensive sense.

상기 유입맨홀(10)은 방류수역(1)에 유입되는 처리수를 포집하고, 수두(水頭) 차를 이용한 자연배제방식으로 상기 처리수에 포함된 나무토막이나 비닐 및 도로·노상의 각종 오염물을 걸러내게 된다.The inflow manhole 10 collects the treated water flowing into the discharge water 1, and removes various contaminants of wood chips, vinyl, and roads and roads contained in the treated water by a natural exclusion method using a water head difference. Filtered out.

이를 위한 실시 예로 상기 유입맨홀(10)은 도 1 내지 2에서 보인 것과 같이 처리수가 유입되는 유입구(11)가 형성되고, 처리수에 포함된 오염물을 걸러내기 위한 스크린망(12)이 내부에 구비되며, 이 스크린망(12)을 통해 오염물이 배제된 처리수를 배수하기 위한 배수구(13)가 하부에 형성된 것을 보이고 있다.In this embodiment, the inlet manhole 10 has an inlet 11 through which treated water is introduced, as shown in FIGS. 1 and 2, and a screen net 12 for filtering contaminants contained in the treated water is provided therein. Through the screen net 12, it is shown that the drain hole 13 for draining the treated water from which the contaminants are excluded.

이때, 상기 유입맨홀(10)은 수두(水頭) 차를 이용한 자연배제방식으로 처리수에서 오염물을 걸러내는 관계로, 방류수역(1)의 가장자리에 해당하는 언덕에 매 설되거나, 상기 방류수역(1)과 가까운 인근 하수방류지점에 매립하게 된다.At this time, the inflow manhole 10 is a natural exclusion method using the head difference (water) difference, so as to filter the contaminants from the treated water, buried in the hill corresponding to the edge of the discharge water (1), or the discharge water ( It will be buried in the nearby sewage discharge branch near 1).

즉, 수두 차에 의한 오염물의 자연배제가 가능하기 위해서는 유입맨홀(10)에 형성된 배수구(13)의 높이(h)가 방류수역(1)의 수면(w)보다 상부에 위치해야 하므로, 이에 해당하는 지면에 상기 유입맨홀(10)이 매설되는 것이다.That is, in order to enable natural removal of contaminants by the head difference, the height h of the drain 13 formed in the inlet manhole 10 should be located above the water surface w of the discharge water zone 1. The inlet manhole 10 is buried in the ground.

따라서, 상기 유입맨홀(10)에 형성된 유입구(11)를 통해 유입된 처리수는 수두 차에 의해 오염물이 스크린망(12)에 걸러진 후 배수구(13)를 통해 여과시설물(20)로 공급된다.Therefore, the treated water introduced through the inlet 11 formed in the inlet manhole 10 is filtered to the filtering facility 20 through the drain hole 13 after the contaminants are filtered out of the screen net 12 by the head difference.

본 발명에 포함되는 여과시설물(20)은 방류수역(1) 내 처리수의 여과처리를 위한 여과공간(21)을 독립적으로 형성하게 된다. 이를 위한 실시 예로 상기 여과시설물(20)은 도 1 또는 3에서 보인 것과 같이, 바닥(22), 이를 둘러싼 차단벽(23) 및 상판(24)으로 구성된 것을 보이고 있으며, 상기 바닥(22)의 둘레를 차단벽(23)으로 두르고, 그 위에 상판(24)을 형성하여 통수 단면이 최대한 형성된 일종의 인공필터층을 형성하게 된다.The filtration facility 20 included in the present invention is to form an filtration space 21 for filtration of the treated water in the discharge water (1) independently. As shown in FIG. 1 or 3, the filtration facility 20 has a bottom 22, a blocking wall 23 and a top plate 24 surrounding the bottom 22. Is enclosed by the barrier wall 23, and the upper plate 24 is formed thereon to form a kind of artificial filter layer having a maximum number of cross sections.

이러한 여과시설물(20)에는 유입맨홀(10)과 연결된 우수관(14)을 결합할 수 있도록 입구(25)를 형성하되, 이 입구(25)는 차단벽(23)의 하부에 형성된 것을 보이고 있다.The inlet 25 is formed in the filtering facility 20 so as to couple the rain pipe 14 connected to the inlet manhole 10, and the inlet 25 is formed below the barrier wall 23.

또한, 상기 여과시설물(20)에는 조대협잡물 및 미세협잡물이 여과된 처리수를 최종 방류하기 위한 출구(26)를 형성하되, 이 출구(26)는 방류수역(1)의 수면(w)보다는 높고 배수구(13)의 높이(h)보다는 낮도록 차단벽(23)의 상부에 형성하되, 더욱 바람직한 실시 예로써 360°방향으로 형성된다.In addition, the filtration facility 20 is formed with an outlet 26 for the final discharge of the treated coarse and fine contaminant filtered water, the outlet 26 is higher than the water surface (w) of the discharge water (1) It is formed in the upper portion of the blocking wall 23 to be lower than the height h of the drain 13, in a more preferred embodiment is formed in a 360 ° direction.

나아가, 상기 차단벽(23)에는 보조필터층(23a)을 형성하여 스크린장치(30) 및 여과장치(31)를 거쳐 여과처리된 처리수를 최종 여과하여 출구(26)를 통해 방류토록 하게 된다.Further, an auxiliary filter layer 23a is formed on the blocking wall 23 to finally filter the treated water filtered through the screen device 30 and the filtration device 31 and discharged through the outlet 26.

따라서, 이와 같은 여과시설물(20)에 의해 방류수역(1) 내에 별도로 독립된 여과공간(21)이 형성됨에 따라 오염물이 자연배제된 처리수를 공급받아 이를 여과한 후 방류수역(1)에 방류하게 되며, 이에 따라 친환경적으로 방류수역(1)의 수질을 유지관리할 수 있게 된다.Therefore, as the separate filtering space 21 is formed in the discharge water 1 by the filtration facility 20, the pollutants are supplied with treated water, which is naturally excreted, and then filtered and discharged into the discharge water 1. Accordingly, it is possible to maintain the water quality of the discharge water (1) environmentally friendly.

여기서, 상기 여과시설물(20)은 출구(26)를 통해 처리수가 역류하는 것을 방지할 수 있도록 단락용 웨어(Weir)를 포함하게 된다. 즉, 상기 단락용 웨어(27)는 도 1에서 보인 것과 같이, 여과시설물(20)을 둘러 형성하되, 처리수가 최종 배수되는 단부를 출구(26)보다 높게 배치하여 상기 출구(26)를 통해 배수되는 처리수를 식생저류부(40)에 배수하고, 반대로 처리수의 역류는 방지토록 하게 된다.Here, the filtration facility 20 includes a short weir to prevent the backflow of the treated water through the outlet 26. That is, the short weir 27 is formed around the filtration facility 20, as shown in Figure 1, the end of the treated water is disposed higher than the outlet 26 to drain through the outlet 26 The treated water is drained to the vegetation reservoir 40, and conversely, the reverse flow of the treated water is prevented.

본 발명에 포함되는 스크린장치(30)는 처리수에 포함된 5㎜를 초과하는 조대협잡물을 여과처리할 수 있도록 여과시설물(20)에 의해 형성된 여과공간(21)에 설치된다.The screen device 30 included in the present invention is installed in the filtration space 21 formed by the filtering facility 20 so as to filter coarse contaminants exceeding 5 mm contained in the treated water.

이를 위한 실시 예로 상기 여과공간(21)에 원통형의 스크린장치(30)가 설치되고, 이 원통형의 스크린장치(30)의 하부에 우수관(14)이 연결된 것을 보이고 있다.For example, the cylindrical screen device 30 is installed in the filtration space 21, and the rain pipe 14 is connected to the lower portion of the cylindrical screen device 30.

즉, 상기 원통형 스크린장치(30)는 유속저하를 통해 처리수 내 조대협잡물을 여과처리하기 위한 것으로, 우수관(14)을 통해 공급된 처리수는 원통형 스크린장 치(30)의 하부에서 상부방향으로 상승하게 된다.That is, the cylindrical screen device 30 is to filter the coarse contaminants in the treated water through the flow rate decrease, and the treated water supplied through the rain pipe 14 is directed upward from the bottom of the cylindrical screen device 30. Will rise.

이 과정에서 처리수의 유속은 서서히 저하되어 조대협잡물은 원통형 스크린장치(30)에 걸려 여과처리되고, 이러한 조대협잡물이 여과된 처리수는 상기 원통형 스크린장치(30)를 통과하여 여과장치(31)로 공급된다.In this process, the flow rate of the treated water is gradually lowered so that the coarse coarse matter is filtered through the cylindrical screen device 30, the treated water filtered through the coarse coarse matter is passed through the cylindrical screen device 30 to filter the device (31) Is supplied.

본 발명에 포함되는 여과장치(31)는 도 3에서 보인 것과 같이, 내장된 필터를 이용하여 스크린장치(30)를 통과한 처리수 내 미세협잡물을 여과처리하게 되며 이를 위한 실시 예로 담체(擔體)와 여재(濾材)를 망 형태의 커튼스크린(31a)에 내장하여 스크린장치(30)의 외부에 배치한 것을 실시 예로 보이고 있다.As shown in FIG. 3, the filtration device 31 included in the present invention filters the fine contaminants in the treated water passing through the screen device 30 using the built-in filter. ) And the filter medium are arranged in the mesh curtain screen 31a and disposed outside the screen device 30.

즉, 상기 여과장치(31)는 유속이 느려지는 스크린장치(30)의 바깥 가장자리에 설치되어 처리수에 포함되어 있는 미세협잡물을 여과하게 된다.That is, the filtration device 31 is installed on the outer edge of the screen device 30, the flow rate is slow to filter the fine contaminants contained in the treated water.

이러한 여과장치(31)의 더욱 바람직한 실시 예로는 스크린장치(30)의 둘레에 커튼스크린(31a)을 방사형으로 다단 설치하여 처리수에 포함되어 있는 미세협잡물을 순차 여과하는 것이며, 배치순서는 상기 스크린장치(30)와 가까운 중심부에는 조대담체와 여재가 내장된 커튼스크린(31a)을 배치하고, 유속이 감속되는 바깥 쪽에 미세담체와 여재가 내장된 커튼스크린(31a)을 배치하는 것이다.A more preferred embodiment of such a filtration device 31 is to install the curtain screen 31a radially in multiple stages around the screen device 30 to sequentially filter the fine contaminants contained in the treated water, and the arrangement order is the screen. In the center close to the device 30 is arranged the curtain screen 31a with the coarse carrier and the media, and the curtain screen 31a with the microcarrier and the media is disposed on the outside where the flow velocity is reduced.

따라서, 우수관(14)을 통해 여과공간(21)으로 공급된 처리수는 스크린장치(30)와 여과장치(31)를 순차적으로 통과하면서 조대협잡물과 미세협잡물이 여과처리된 후 여과시설물(20)의 가장자리 통수 단면을 거쳐 상기 여과시설물(20)의 상부에 형성된 입구(25) 또는 강우시 단락용 웨어(27)를 통해 방류된다.Accordingly, the treated water supplied to the filtration space 21 through the rain pipe 14 passes through the screen device 30 and the filtration device 31 sequentially, after which coarse and fine contaminants are filtered. It is discharged through the inlet 25 formed in the upper portion of the filtration facility 20 or the short-circuit weir 27 during the rainfall.
