Description

초기우수처리를 위한 비점오염물질 저감장치{NON-POINT CONTAMINANT REDUCING DEVICE FOR TREATMENT OF FIRST RAIN WATER}Non-point pollutant reduction device for initial rainwater treatment {NON-POINT CONTAMINANT REDUCING DEVICE FOR TREATMENT OF FIRST RAIN WATER}

본 발명은 초기우수에 포함된 유기영양염류, 중금속, 오일류, 각종 협잡물 등의 비점오염물질을 정화시키고, 우수량에 관계없이 유입된 우수를 원활히 배수시킬 수 있는 초기우수처리를 위한 비점오염물질 저감장치에 관한 것이다.The present invention purifies non-point pollutants such as organic nutrients, heavy metals, oils, and various contaminants included in the initial rainwater, and reduces nonpoint pollutants for initial rainwater treatment that can smoothly drain the rainwater that has flowed in regardless of the amount of rain. It relates to the device.

일반적으로 오염물질은 점오염물질과 비점오염물질로 구분할 수 있는데, 점오염물질은 생활하수, 산업폐수 및 축산폐수 등과 같이 배출지점이 명확한 곳으로부터 배출되며, 이러한 점오염물질은 대부분 정화장치나 폐수처리시설을 설치하여 오염물질을 효율적으로 정화시킬 수 있다. In general, pollutants can be classified into point pollutants and nonpoint pollutants.Point pollutants are discharged from places with clear discharge points, such as household sewage, industrial wastewater, and livestock wastewater, and most of these point pollutants are purifiers or wastewater. By installing treatment facilities, pollutants can be efficiently purified.

반면 비점오염물질은 농경지, 목초지, 산림지, 건축현장, 광산, 쓰레기 매립장, 도로 및 산업현장 등과 같이 배출지점이 불명확하고 광범위한 곳으로부터 배출되며, 수집이 어렵고 배출량의 변화가 심하여 처리시설의 설계 및 유지관리가 어려운 문제점이 있다.On the other hand, non-point pollutants are discharged from unclear and wide areas such as agricultural land, grassland, forest land, construction sites, mines, waste landfills, roads and industrial sites, and are difficult to collect and change in emissions, so design and maintain treatment facilities. There is a problem that is difficult to manage.

비점오염물질이 지표면에 잔존해 있는 경우에는 강우시 지표면을 흐르는 우수에 섞이게 되는데, 이로 인해 비가 내리고 일정 시간이 경과한 이후의 우수에 비해 초기우수에는 많은 비점오염물질이 포함되어 있다.When non-point pollutants remain on the surface, they are mixed with rainwater flowing through the surface during rainfall.As a result, there are many non-point pollutants in the initial rainfall compared to the rain after a certain period of time after rain.

이러한 비점오염물질이 초기 우수와 함께 하천, 내만, 호수 등의 공공수역이나 지하수로 흘러들어가는 경우에는 수질을 오염시킬 뿐만 아니라 생태계를 파괴하는 주된 원인이 된다.When these non-point pollutants flow into public waters or groundwater such as rivers, inner bays, and lakes along with the initial rain, they not only pollute the water quality but also become the main cause of destroying the ecosystem.

이에 따라 수질오염을 방지하고 생태계 보호를 위한 비점오염원 관리의 중요성이 더욱 증대되고 있으며, 도로나 교량 등을 건설시에 노면의 배수를 위해 정화장치를 필수적으로 설치하도록 시설 기준 상에 명시하고 있다.Accordingly, the importance of non-point source management for preventing water pollution and protecting the ecosystem is increasing, and it is specified in the facility standards to install a purification device for drainage of the road surface when constructing roads or bridges.

종래에는 한국등록특허공보 제10-0958326호와 같이 초기우수에 포함된 비점오염물질을 제거하기 위해 제1저장소, 식생처리부, 침투처리부 및 제2저장소로 구성된 침투 및 식생을 이용한 초기우수처리장치가 제안되었다. Conventionally, as in Korean Registered Patent Publication No. 10-0958326, in order to remove non-point pollutants included in the initial rainwater, an initial rainwater treatment device using infiltration and vegetation consisting of a first reservoir, a vegetation treatment section, a penetration treatment section, and a second reservoir is Was proposed.

그러나 상기한 초기우수처리장치는 제1저장소로 유입된 초기우수가 식생처리부로 이동되기 전에 제1저장소 내에 구비된 자갈층 및 바닥에 구비된 복수개의 홀을 통해 유출됨에 따라 비점오염물질이 제대로 여과되지 못하는 문제점이 있었다.However, in the above-described initial rainwater treatment device, nonpoint pollutants were not properly filtered as the initial rainwater flowing into the first reservoir flows out through a plurality of holes provided in the gravel layer and bottom provided in the first reservoir before it is moved to the vegetation treatment section. There was a problem that could not be done.

또한 식생처리부 역시도 제1저장소에서 제1유출로를 통해 이동하는 우수를 여과하도록 된 것임에 따라, 제1유출로를 통해 우수가 유입되는 측과 제2저장소로 우수가 배출되는 측의 여과량이 서로 달라지게 되는데, 이로 인하여 식생처리부에 유입된 우수가 균일하게 배출되지 못하게 배수효율이 저하되는 원인이 되며, 이는 결국 다량의 우수가 일시에 유입될 경우 초기우수에 포함된 비점오염물질의 처리효율이 저하되는 문제로 이어졌다.In addition, as the vegetation treatment unit is also designed to filter the rainwater moving from the first reservoir through the first outlet passage, the amount of filtration on the side where rainwater flows through the first outlet passage and the side where rainwater is discharged to the second reservoir This causes the drainage efficiency to be lowered so that the rainwater flowing into the vegetation treatment unit cannot be uniformly discharged. This is, in the end, the treatment efficiency of non-point pollutants contained in the initial rainwater when a large amount of rainwater is introduced at once. It led to a deteriorating problem.

이에 본 출원인은 한국공개특허공보 제10-2016-0148950호와 같이, 다량의 우수가 일시에 공급되는 경우에도 초기우수에 포함된 비점오염물질을 효율적으로 여과시킴은 물론 원활하게 우수를 배수시키기 위하여, 집수부에 유입된 우수를 다수개의 식생처리부와 침투처리부로 나누어 공급받아 여과시키고, 비점오염물질이 여과된 우수가 우수처리부를 통해 재차 여과되면서 하방으로 배수되면, 우수저장부 내에 유입된 우수가 충분한 시간 동안 머무르며 우수처리블록의 하부로 배출될 수 있는 초기우수 처리장치를 제안한 바 있다.Accordingly, the applicant, as in Korean Patent Laid-Open Publication No. 10-2016-0148950, in order to efficiently filter the non-point pollutants contained in the initial rainwater even when a large amount of rainwater is supplied at one time, as well as to smoothly drain rainwater. , Rainwater flowing into the water collecting unit is divided into a plurality of vegetation treatment units and penetration treatment units and filtered. When the rainwater from which non-point pollutants have been filtered is filtered again through the rainwater treatment unit and is drained downward, the rainwater flowing into the stormwater storage unit is An initial rainwater treatment device that stays for a sufficient time and can be discharged to the bottom of the rainwater treatment block has been proposed.

하지만 우수저장부에 유입된 우수는 비점오염물질이 제거된 것이지만, 미세한 이물질이 포함된 상태로 유입되기 때문에, 일정 시간을 머무르는 동안 우수저장부의 바닥면에는 침전물이 퇴적된다.However, the rainwater flowing into the stormwater storage unit is that non-point pollutants have been removed, but since it is introduced in a state containing fine foreign substances, sediments are deposited on the bottom surface of the stormwater storage unit during a certain period of time.

이에 본 출원인은 우수저장부 내에 퇴적된 침전물을 폭기시켜 부유시킨 후 그 부유된 침전물을 흡입 및 배출시키도록 구성하였으나, 이미 퇴적되어 고형화된 침전물까지 부유시키기는 어려웠으며, 이로 인해 고형화된 침전물을 제거하기 위한 해체 및 재설치 작업이 수시로 이루어져야 함에 따라 유지보수에 소요되는 비용이 증대될 수 밖에 없는 문제가 있었다.Therefore, the applicant of the present invention was configured to aerate the sediment deposited in the storm water storage and then inhale and discharge the suspended sediment, but it was difficult to float even the sediment that had already been deposited and solidified, thereby removing the solidified sediment. As the dismantling and re-installation work must be performed frequently, there is a problem that the cost required for maintenance is inevitably increased.

본 발명의 일실시예에 따른 초기우수처리를 위한 비점오염물질 저감장치는 도 1 내지 3에 도시한 바와 같이 크게 침전조(10), 여과조(20), 유량분배셀(30), 제1여과처리부(40), 제2여과처리부(50), 월류처리수로(60)를 포함하여 구성된 것을 특징으로 한다.The apparatus for reducing non-point pollutants for initial rainwater treatment according to an embodiment of the present invention is largely a settling tank 10, a filtration tank 20, a flow distribution cell 30, and a first filtration treatment unit as shown in FIGS. (40), characterized in that it is configured to include a second filtration treatment unit (50), and an overflow treatment channel (60).

상기의 침전조(10)는 강우시 노면으로부터 유입된 우수가 집수되도록 형성된 것으로, 일 측벽면과 상부면 중 적어도 하나의 곳을 통해 우수가 유입되도록 형성되며, 상면을 통해 우수가 유입되도록 한 경우에는 부피가 큰 이물질이 함께 유입되는 것을 방지하기 위한 그레이팅부재(11)가 분해 결합 가능하게 설치되는 것이 바람직하다.The sedimentation tank 10 is formed to collect rainwater introduced from the road surface during rainfall, and is formed so that rainwater flows through at least one of one sidewall and upper surface, and when rainwater flows through the upper surface, It is preferable that a grating member 11 for preventing bulky foreign substances from flowing together is installed to be disassembled and coupled.

이러한 침전조(10)의 일측에는 집수량이 설정된 높이에 도달하게 된 경우, 그 설정된 높이를 초과하여 집수되는 우수가 침전조(10)의 외부로 배출되도록 하는 우수이동관(15)이 설치된다.On one side of the sedimentation tank 10, when the water collection amount reaches a set height, a rainwater transfer pipe 15 is installed so that rainwater collected in excess of the set height is discharged to the outside of the sedimentation tank 10.

상기의 여과조(20)는 침전조(10)의 일측에 우수이동관(15)으로부터 배출된 우수를 공급받도록 설치된 것으로, 이러한 여과조(20)의 하면에는 우수에 포함된 비점오염물질이 여과 처리되어 지하에 배출되도록 다수개의 배수홀(21)이 형성된다.The filtration tank 20 is installed to receive the rainwater discharged from the rainwater transfer pipe 15 on one side of the sedimentation tank 10, and the non-point pollutants contained in the rainwater are filtered and treated underground. A plurality of drainage holes 21 are formed to be discharged.

상기의 유량분배셀(30)은 여과조(20)의 내부 상측에 설치되어 우수이동관(15)에서 배출된 우수를 공급받아 하방으로 배수하도록 형성된 것이다.The flow distribution cell 30 is installed on the upper side of the filter tank 20 to receive the rainwater discharged from the rainwater transfer pipe 15 and drain it downward.

이러한 유량분배셀(30)은 자갈, 흙, 식물 등이 포함된 식생층을 이루는 식생처리부(31)와, 조경석, 자갈, 숯, 금속망 등이 포함된 여재층을 이루는 침투처리부(32)가 각각 복수개 구비된 것이다.The flow distribution cell 30 includes a vegetation treatment unit 31 constituting a vegetation layer containing gravel, soil, plants, etc., and a penetration treatment unit 32 constituting a filter material layer including landscaping stone, gravel, charcoal, metal mesh, etc. Each is equipped with a plurality.

이때 식생처리부(31)와 침투처리부(32)는 첨부한 도면에 도시한 바와 같이 내부를 복수개의 공간으로 구획하도록 설치된 구획벽(33)에 의해 식생층과 여재층이 수용되는 공간이 구분되도록 할 수 있으며, 이와는 달리 상부가 개구되고 내부에 수용공간이 마련된 수용체(미도시)를 다수개 구비해 식생층이 수용된 수용체는 식생처리부(31)로 사용하고 여재층이 수용된 수용체는 침투처리부(32)로 사용할 수도 있는 것이다.At this time, the vegetation treatment unit 31 and the infiltration treatment unit 32 are arranged to divide the space in which the vegetation layer and the filter media layer are accommodated by a partition wall 33 installed to divide the interior into a plurality of spaces, as shown in the accompanying drawings. Unlike this, a plurality of receptors (not shown) with an open top and an accommodation space are provided, so that the receptors containing the vegetation layer are used as the vegetation treatment unit 31, and the receptors containing the filter media layer are the penetration treatment units 32 It can also be used as.

여기서 식생처리부(31)는 우수이동관(15)을 통해 공급된 우수가 식생층을 거치며 우수에 포함된 비점오염물질이 여과되도록 하는 것이고, 침투처리부(32)는 강우량의 증가로 인해 우수이동관(15)을 통해 공급된 우수가 식생처리부(31) 만으로처리되지 못하고 월류하는 경우 그 식생처리부(31)로부터 월류한 우수를 공급받아 분산되어 배수되도록 하는 것이다.Here, the vegetation treatment unit 31 is to allow the rainwater supplied through the rainwater transfer pipe 15 to pass through the vegetation layer and filter non-point pollutants contained in the rainwater, and the penetration treatment unit 32 is the rainwater transfer pipe 15 due to an increase in rainfall. ), when the rainwater supplied through the vegetation treatment unit 31 is not treated and overflows, the rainwater that has overflowed from the vegetation treatment unit 31 is supplied and dispersed and drained.

상기의 구획벽(33) 또는 수용체에는 식생처리부(31)와 침투처리부(32) 사이가 서로 연통되게 관통시킨 연통홀(34)을 복수개 형성시켜, 식생처리부(31)에 유입되는 우수의 배수효율을 증대시키면서도, 침투처리부(32)에 유입된 우수가 인접한 다른 식생처리부(31)에 유입되어 비점오염물질이 여과 처리될 수 있도록 하는 것이 바람직하다.A plurality of communication holes 34 through which the vegetation treatment part 31 and the penetration treatment part 32 are communicated with each other are formed in the partition wall 33 or the receptor, so that excellent drainage efficiency flowing into the vegetation treatment part 31 While increasing, it is preferable that rainwater flowing into the permeation treatment unit 32 flows into the adjacent vegetation treatment unit 31 so that non-point pollutants can be filtered.

상기의 제1여과처리부(40)는 유량분배셀(30)의 하부에 설치되어 식생처리부(31)와 침투처리부(32)를 거쳐 하방으로 배출된 우수를 공급받고, 우수에 포함된 비점오염물질을 여과시키도록 형성된 제1여과재(41)가 채워지며, 그 제1여과재(41)에 의해 여과 처리된 제1여과수가 하방으로 배수되도록 형성된 것이다.The first filtration treatment unit 40 is installed under the flow distribution cell 30 to receive rainwater discharged downward through the vegetation treatment unit 31 and the penetration treatment unit 32, and non-point pollutants included in the rainwater. The first filter material 41 formed to filter the is filled, and the first filter water filtered by the first filter material 41 is formed to be drained downward.

상기의 제2여과처리부(50)는 하부면이 여과조(20)의 바닥면에 놓여 지지된 상태로 제1여과처리부(40)의 하부에 제1여과수를 공급받도록 설치되고, 제1여과수를 여과시키도록 형성된 제2여과재(51)가 채워지며, 그 제2여과재(51)에 의해 여과 처리된 제2여과수가 하방으로 배수되어 여과조(20) 하부의 배수홀(21)을 통해 배출되도록 형성된 것이다.The second filtration treatment unit 50 is installed to receive the first filtrate under the first filtration treatment unit 40 while the lower surface is supported by being placed on the bottom surface of the filtration tank 20, and filters the first filtrate. The second filter medium 51 formed to be filtered is filled, and the second filtered water filtered by the second filter material 51 is drained downward and is discharged through the drain hole 21 under the filter tank 20. .

이때 제2여과재(51)의 크기는 제1여과재(41) 보다 큰 크기로 형성된 것이 바람직한데, 이는 이미 여과조(20)의 상측에 유입된 우수가 식생처리부(31)와 제1여과처리부(40)를 거치는 동안 우수에 포함된 비점오염물질이 충분히 제거되기 때문에, 미처 제거되지 못한 비점오염물질이 제2여과재(51)를 거치면서 마저 제거되도록 함과 동시에 배수의 효율을 증대시키기 위함이다.At this time, the size of the second filter material 51 is preferably formed to be larger than the first filter material 41, which is the rainwater that has already flowed into the upper side of the filter tank 20, the vegetation treatment unit 31 and the first filter treatment unit 40 ), since the non-point pollutants contained in the rainwater are sufficiently removed while passing through), the non-point pollutants that have not yet been removed are removed while passing through the second filter material 51, and at the same time, the efficiency of drainage is increased.

상기의 월류처리수로(60)는 제2여과처리부(50)의 양측에 설치되고, 배수홀(21)을 통해 배수되지 못한 제2여과수가 월류되어 유입되는 월류수유입구(61)가 형성되며, 그 월류수유입구(61)를 통해 유입된 월류수가 여과조(20)의 일측으로 배출되어 하수 처리되도록 하기 위한 월류수배출구(62)가 구비된다.The overflow treatment water passage 60 is installed on both sides of the second filter treatment unit 50, and overflow water inlets 61 through which the second filtered water that has not been drained through the drain hole 21 overflows and flows into, are formed, A overflow water outlet 62 for discharging the overflow water introduced through the overflow water inlet 61 to one side of the filtering tank 20 to be treated for sewage is provided.

여기서 월류처리수로(60)는 여과조(20)의 길이방향에 해당하는 측벽부와 대응되는 길이로 형성시키고, 월류수유입구(61)는 월류수처리수로(60)가 설치되는 길이방향을 따라 제2여과처리부(50)와 마주하는 측벽부 상측에 형성시켜, 제2여과처리부(50)에서 배수되지 못하고 채워지는 제2처리수가 원활하게 월류되어 유입될 수 있도록 하는 것이 바람직하다. Here, the overflow treatment water channel 60 is formed to have a length corresponding to the side wall portion corresponding to the longitudinal direction of the filtration tank 20, and the overflow water inlet 61 is formed along the longitudinal direction in which the overflow treatment water channel 60 is installed. It is preferable that the second treated water which cannot be drained from the second filter treatment part 50 and is filled without being drained from the second filter treatment part 50 is smoothly overflowed and introduced therein by forming it on the upper side of the side wall part facing the second filter treatment part 50.

이러한 월류처리수로(60)는 월류수유입구(61)에 월류되어 유입된 제2처리수가 월류수배출구(62)를 통해 신속하게 배수될 수 있도록 하기 위해서, 월류수배출구(62) 측이 하방에 위치하도록 경사지게 설치하거나, 또는 월류처리수로(60)의 바닥면을 월류수배출구(62) 측으로 기울어지게 형성하는 것이 바람직하다.In order to allow the second treated water overflowed to the overflow water inlet 61 to be quickly drained through the overflow water discharge port 62, the overflow treatment water channel 60 is positioned at the bottom of the overflow water discharge port 62. It is preferable to install it in an inclined manner, or to form the bottom surface of the overflow treatment waterway 60 to be inclined toward the overflow water outlet 62.

이때 월류처리수로(60)는 여과조(20)의 중앙부 바닥면에 접촉되게 설치되거나 또는 제2여과처리부(50)에 채워지는 제2여과재(51)를 사이에 두고 여과조(20)의 내측 벽면과 바닥면에 접촉된 채로 지지되게 설치될 수 있다.At this time, the overflow treatment water channel 60 is installed to be in contact with the bottom surface of the central portion of the filtration tank 20, or the inner wall surface of the filtration tank 20 with the second filter material 51 filled in the second filtration treatment unit 50 interposed therebetween. It can be installed to be supported while in contact with the and the bottom surface.

상기의 월류수유입구(61)는 첨부한 도면과 같이 측벽면에 설정된 높이로 형성될 수 있으나, 이와는 달리 월류처리수로(60)의 상부면에 배수홀(21)을 통해 배수되지 못한 제2여과수가 월류되어 유입될 수 있도록 형성될 수 있는 것이다.The overflow water inlet 61 may be formed at a height set on the side wall as shown in the accompanying drawings, but unlike this, the second filtered water that cannot be drained through the drain hole 21 on the upper surface of the overflow treatment waterway 60 It can be formed so that it can overflow and flow in.

또한 월류수배출구(62)를 통해 배출된 월류수는 지하로 배출 처리되는 것이 아니라 하수관으로 배출 처리되는 것인 만큼, 월류수배출구(62)의 끝단부를 하수관(미도시)과 연결되게 설치하여, 월류수배출구(62)를 통해 배출된 월류수가 곧바로 하수 처리될 수 있도록 하는 것이 바람직하다.In addition, as the overflow water discharged through the overflow water discharge port 62 is not discharged underground but is discharged to a sewage pipe, the end of the overflow water discharge port 62 is installed to be connected to a sewage pipe (not shown), and the overflow water discharge port ( 62), it is desirable to allow sewage treatment to be treated immediately.

상기와 같은 구성으로 이루어진 초기우수처리를 위한 비점오염물질 저감장치에 대한 작용효과를 살펴보면 다음과 같다.Looking at the effect of the non-point pollutant reduction device for the initial excellent treatment consisting of the above configuration is as follows.

강우가 시작되면 노면으로부터 유입된 우수는 도로 또는 교량의 측구에 설치된 수로를 따라 이동하여 침전조(10)에 집수된다.When rainfall begins, rainwater flowing from the road surface moves along the waterway installed at the side of the road or bridge, and is collected in the sedimentation tank 10.

침전조(10)에 우수의 집수량이 증가하여 우수이동관(15)에 이르는 높이로 채워지면 우수이동관(15)이 설치된 높이를 초과하여 집수되는 우수는 우수이동관(15)을 이동하여 여과조(20)의 상측으로 배출된다.When the amount of rainwater collected in the sedimentation tank (10) increases and is filled to the height of the rainwater transfer pipe (15), the rainwater collected beyond the height of the rainwater transfer pipe (15) is moved to the filtering tank (20). Is discharged to the upper side of.

여과조(20)의 상측으로 배출된 우수는 유량분배셀(30)에 구비된 식생처리부(31)에 공급되고, 식생처리부(31)에 공급된 우수는 식생층을 거치며 여과 처리되어 하방으로 배수된다.Rainwater discharged to the upper side of the filtration tank 20 is supplied to the vegetation treatment unit 31 provided in the flow distribution cell 30, and the rainwater supplied to the vegetation treatment unit 31 is filtered through the vegetation layer and drained downward. .

이때 식생처리부(31)에서 처리할 수 있는 양을 초과하여 유입된 우수는 식생처리부(31)를 월류하여 침투처리부(32)에 공급되며, 침투처리부(32)에 공급된 우수는 여재층을 거치며 고루 분산된 상태로 하방으로 배수된다.At this time, rainwater introduced in excess of the amount that can be treated by the vegetation treatment unit 31 is supplied to the permeation treatment unit 32 by overflowing the vegetation treatment unit 31, and the rainwater supplied to the penetration treatment unit 32 passes through the filter media layer. It is evenly distributed and drained downwards.

유량분배셀(30)에서 식생처리부(31)만을 통해 배출되거나 또는 식생처리부(31)와 침투처리부(32)에서 함께 배출된 우수는 유량분배셀(30)의 하부에 위치한 제1여과처리부(40)에 공급된다.The rainwater discharged from the flow distribution cell 30 only through the vegetation treatment unit 31 or both from the vegetation treatment unit 31 and the infiltration treatment unit 32 is a first filter treatment unit 40 located under the flow distribution cell 30. ).

제1여과처리부(40)에 공급된 우수는 제1여과재(41)를 거치면서 비점오염물질이 제거되고, 제1여과재(41) 사이를 지나면서 분산되어 배수되며, 제1여과재(41)에 의해 여과 처리되어 배수된 제1여과수는 제1여과처리부(40)의 하부에 위치한 제2여과처리부(50)에 공급된다.Rainwater supplied to the first filter treatment unit 40 is removed from non-point pollutants while passing through the first filter material 41, is dispersed and drained while passing through the first filter material 41, The first filtered water that has been filtered and drained by the filter is supplied to the second filtering unit 50 located below the first filtering unit 40.

제2여과처리부(50)에 공급되는 우수는 제2여과재(51)를 거치면서 비점오염물질이 제거되고, 제2여과재(51) 사이를 지나면서 분산되어 배수되며, 제2여과재(51)에 의해 여과 처리되어 배수된 제2여과수는 여과조(20)의 하부면에 형성된 배수홀(21)을 통해 지하에 배출된다.Rainwater supplied to the second filter material 50 is removed from non-point pollutants while passing through the second filter material 51, is dispersed and drained while passing through the second filter material 51, and is discharged to the second filter material 51. The second filtrate water filtered and drained by the filter tank 20 is discharged to the basement through a drain hole 21 formed in the lower surface of the filter tank 20.

이처럼 비점오염물질이 포함된 초기우수가 공급되면, 여과조(20)에 구비된 식생처리부(31), 제1여과재(41) 및 제2여과재(51)를 순차적으로 거치며 단계적으로 여과되어 처리됨으로써, 초기우수에 포함된 비점오염물질을 안전하게 처리하여 배출시킬 수 있다.When the initial excellent water containing non-point pollutants is supplied as described above, the vegetation treatment unit 31, the first filter material 41, and the second filter material 51 provided in the filter tank 20 are sequentially passed through, and are filtered and processed in stages, Non-point pollutants contained in the initial rainwater can be safely treated and discharged.

이때 제2여과처리부(50)에서 배수홀(21)을 통해 제2여과수가 배수되는 양에 비해 제1여과처리부(40)에서 제1여과수가 공급되는 양이 많은 경우에는, 여과조(20)의 바닥면에서부터 차오른 제2여과수가 여과조(20)의 하부에 위치한 제2여과처리부(50)에 채워지게 된다.At this time, when the amount of the first filtered water supplied from the first filtering unit 40 is larger than the amount of the second filtered water discharged from the second filtering unit 50 through the drain hole 21, the filter tank 20 The second filtered water, which has risen from the bottom surface, is filled in the second filtering unit 50 located below the filtering tank 20.

이러한 경우에는, 도 4와 같이 제2여과처리부(50)에서 배수홀(21)을 통해 배수되지 못하고 제2여과처리부(50)에 채워지는 제2여과수가 월류수유입구(61)에 이르는 높이로 채워지게 되는데, 제2여과처리부(50)에 월류수유입구(61)를 초과하는 높이로 채워진 제2여과수는 월류수유입구(61)를 통해 월류처리수로(60) 내에 월류하여 유입된다.In this case, as shown in FIG. 4, the second filtration water cannot be drained through the drainage hole 21 from the second filtration treatment unit 50, and the second filtration water filled in the second filtration treatment unit 50 is filled to a height reaching the overflow inlet 61. The second filtrate filled with a height exceeding the overflow water inlet 61 in the second filtration treatment unit 50 overflows and flows into the overflow treatment waterway 60 through the overflow water inlet 61.

이를 통해 일시에 다량의 우수가 유입되는 경우에는 제2차여과처리부(20)에서 여과 처리된 제2처리수가 월류처리수로(60)를 통해 신속하고 원활하게 배수됨으로써, 강우특성에 영향을 받지 않고 안정적인 투수성을 확보할 수 있는 이점이 있다.Through this, when a large amount of rainwater flows in at a time, the second treated water filtered by the second secondary filtration treatment unit 20 is quickly and smoothly drained through the overflow treatment waterway 60, so that it is not affected by rainfall characteristics. There is an advantage of securing a stable water permeability without.

게다가 상기의 월류처리수로(60)는 여과조(20) 내에 설치되는 것임에 따라, 다량으로 유입된 우수를 처리하기 위하여 별도의 설치공간을 마련할 필요가 없고, 여과조(20)의 부피를 증대시킬 필요가 없으므로, 시설물 시공에 소요되는 작업시간을 현저히 단축시킬 수 있는 이점이 있다.In addition, since the overflow treatment water channel 60 is installed in the filtration tank 20, there is no need to provide a separate installation space to treat rainwater that has flowed in a large amount, and the volume of the filtration tank 20 is increased. Since there is no need to do so, there is an advantage of remarkably shortening the working time required for facility construction.

이후 월류처리수로(60) 내에 유입된 월류수는 월류수배출구(62)를 통해 배출되어 하수 처리되는데, 이는 월류수배출구(62)를 통해 배출되는 월류수가 지하에 배출되지 않도록 함으로써, 지하에 다량의 우수가 빠른 시간 내에 침투되어 지반이 약화되는 것을 방지하기 위함이다.After that, the overflow water flowing into the overflow treatment waterway 60 is discharged through the overflow water outlet 62 to be treated for sewage, which prevents the overflow water discharged through the overflow water discharge port 62 from being discharged to the basement. This is to prevent the ground from being weakened by infiltrating within a short time.

여기서 상기의 유량분배셀(30), 제1여과처리부(40), 제2여과처리부(50) 및 월류처리수로(60)는 각각이 하나의 묶음 단위로 이루어져 그 묶음 단위로 여과조(20) 내에 설치 및 분리할 수 있는 단위체로 이루어진 것일 수 있다.Here, the flow distribution cell 30, the first filtration treatment unit 40, the second filtration treatment unit 50, and the overflow treatment water channel 60 are each composed of one bundle unit, and the filtration tank 20 It may be made of a unit that can be installed and separated within.

이때 단위체로 이루어진 각 구성 중에서 유량분배셀(30)에 구비된 식생처리부(31)와 침투처리부(32), 제1여과처리부(40)에 채워지는 제1여과재(41), 제2여과처리부(50)에 채워지는 제2여과재(51)는 배수를 위한 통공이 다수개 형성된 틀체 또는 그물 형태의 망체 내에 수용시켜, 배수 효율이 저하되는 것을 방지하면서도 묶음 단위로 이루어진 각 단위체를 이용해 쉽게 설치 및 분리할 수 있도록 하는 것이 바람직하다.At this time, among the components consisting of a unit, the vegetation treatment unit 31 and the infiltration treatment unit 32 provided in the flow distribution cell 30, the first filter material 41 and the second filter treatment unit to be filled in the first filter treatment unit 40 ( The second filter material 51 filled in 50) is accommodated in a frame body or a net-shaped mesh body having a plurality of through-holes for drainage, preventing the drainage efficiency from deteriorating, but easily installed and separated using each unit consisting of a bundle unit. It is desirable to be able to do it.

이처럼 초기우수에 포함된 비점오염물질을 여과하기 위하여 복수개의 여과층을 이루도록 설치되는 각각의 구성이 단위체로 이루어지는 경우에는, 여과조(20) 내에 신속하게 설치할 수 있음은 물론이고, 오랜 기간 사용하여 여과 효율이 저하되는 시점에서는 단위체로 이루어진 각각의 구성을 여과조(20) 내에서 쉽게 꺼내어 분리시킨 후 새로운 구성품으로 교체하여 설치가 가능하다.In this way, in the case where each of the components installed to form a plurality of filtration layers to filter the non-point pollutants contained in the initial rainwater is composed of a unit, it can be quickly installed in the filtration tank 20, as well as filtration after a long period of use. When the efficiency decreases, each component composed of a unit can be easily removed from the filter tank 20, separated, and replaced with a new component for installation.

이에 따라, 시공 현장에서 신속한 시공이 가능하여 작업의 편의성을 현저히 증대시키고, 분리와 교체시공이 용이하여 관리 및 유지보수의 편의성을 현저히 증대시킬 수 있는 이점이 있다.Accordingly, there is an advantage of remarkably increasing the convenience of work by enabling rapid construction at the construction site, and of remarkably increasing the convenience of management and maintenance by easy separation and replacement construction.

한편, 상기의 월류처리수로(60) 내에는 월류수를 배수 처리하는 과정에서 월류수 내에 포함된 이물질이 침전되어 퇴적됨에 따라, 월류수의 배수 처리가 원활하지 못하게 되는 경우가 발생한다.On the other hand, in the process of draining the overflow water in the overflow treatment waterway 60, foreign substances contained in the overflow water are precipitated and deposited, so that the drainage treatment of the overflow water may not be smoothly performed.

이러한 문제를 해결하기 위해서 본 발명의 일실시예에 따른 초기우수처리를 위한 비점오염물질 저감장치는, 침전조(10)에 집수된 우수를 월류처리수로(60)에 공급하여 세척하는데 사용할 수 있도록 하기 위해서, 우수공급펌프(70)와 세척수흡입관(75) 및 세척수배출관(76)의 구성을 더 포함하여 구성될 수 있다.In order to solve this problem, the device for reducing non-point pollutants for initial rainwater treatment according to an embodiment of the present invention supplies rainwater collected in the sedimentation tank 10 to the overflow treatment waterway 60 so that it can be used for washing. In order to do so, it may be configured to further include a configuration of the rainwater supply pump 70, the washing water intake pipe 75 and the washing water discharge pipe 76.

상기의 우수공급펌프(70)는 흡입부(71)를 통해 강제로 흡입하여 배출부(72)로 배출시킬 수 있도록 형성된 것이고, 세척수흡입관(75)은 침전조(10)에 집수된 우수가 우수공급펌프(70)에 의해 흡입부(71)에 공급될 수 있도록 침전조(10)와 흡입부(71)가 연결되게 설치된 것이며, 세척수배출관(76)은 우수공급펌프(70)에서 강제로 흡입하여 배출부(72)로 배출되는 우수가 월류처리수로(60)에 공급될 수 있도록 배출부(72)와 월류처리수로(60)가 연결되게 설치된 것이다.The rainwater supply pump 70 is formed to be forcibly sucked through the suction unit 71 and discharged to the discharge unit 72, and the washing water suction pipe 75 supplies the rainwater collected in the sedimentation tank 10 The settling tank 10 and the suction part 71 are connected to each other so that they can be supplied to the suction part 71 by the pump 70, and the washing water discharge pipe 76 is forcibly sucked and discharged from the rainwater supply pump 70. The discharge unit 72 and the overflow treatment water channel 60 are installed to be connected so that the rainwater discharged to the unit 72 can be supplied to the overflow treatment water channel 60.

이를 통해 도 5와 같이 다량의 우수가 유입되어 월류처리수로(60)에 유입된 월류수를 처리하고 난 이후에 우수공급펌프(70)를 구동시키면, 침전조(10) 내에 집수된 우수가 세척수흡입관(75) → 흡입부(71) → 배출부(72) → 세척수배출관(76)을 거쳐 월류처리수로(60) 내에 강제로 공급되며, 월류처리수로(60) 내에 강제로 공급된 우수를 이용해 월류처리수로(60) 내부를 세척할 수 있다.Through this, when a large amount of rainwater flows in as shown in FIG. 5 and the stormwater supply pump 70 is operated after treating the overflow water flowing into the overflow treatment waterway 60, the rainwater collected in the sedimentation tank 10 is washed water suction pipe. (75) → Suction unit (71) → Discharge unit (72) → It is forcibly supplied into the overflow treatment waterway 60 through the washing water discharge pipe 76, and rainwater forcibly supplied into the overflow treatment waterway 60 It can be used to clean the inside of the overflow treatment waterway (60).

이러한 세척 과정에서 월류처리수로(60)의 바닥면에 침전된 이물질은 우수공급펌프(70)를 통해 공급된 우수와 함께 월류수배출구(62)를 통해 배출되어 하수처리하면 된다.In this washing process, the foreign matter deposited on the bottom surface of the overflow treatment waterway 60 is discharged through the overflow water outlet 62 together with the rainwater supplied through the stormwater supply pump 70 to treat sewage.

이처럼, 침전조(10) 내에 채워진 우수를 이용해 월류처리수로(60) 내부를 세척하는 용도로 활용함으로써, 월류처리수로(60)를 세척하기 위한 세척수를 별도로 구비해야 하는 번거로움을 해소할 수 있으면서도, 항시 안정적인 배수 처리 상태를 유지시킬 수 있고, 월류처리수로(60)의 유지관리 주기를 늘릴 수 있어, 관리 및 유지보수의 편의성을 증대시킬 수 있는 효과가 있는 것이다.In this way, by using the rainwater filled in the sedimentation tank 10 to clean the inside of the overflow treatment waterway 60, it is possible to eliminate the hassle of having to separately provide washing water for cleaning the overflow treatment waterway 60. While still, it is possible to maintain a stable drainage treatment state at all times, and it is possible to increase the maintenance cycle of the overflow treatment waterway 60, thereby increasing the convenience of management and maintenance.
