In describing the present embodiment, the same names are used for the same components, and further description thereof will be omitted.

도 1은 본 발명에 따른 멤브레인을 이용한 오폐수 및 비점오염 여과장치를 나타내는 처리계통도이다.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a processing diagram showing a wastewater and non-point pollution filtration apparatus using a membrane according to the present invention.

본 발명의 멤브레인을 이용한 오폐수 및 비점오염 여과장치는 오수처리시설의 후단에 설치하는 지상노출형으로서, 도 1에 도시된 바와 같이 전처리조(100), 여과막조(200) 및 활성탄 여과조(300)를 포함하여 구성된다.1, the pretreatment tank 100, the filtration membrane tank 200, and the activated carbon filtration tank 300 are connected to each other, .

전처리조(100)와 여과막조(200)는 하나의 하우징 내에 구획된 형태로 연속 설치되고, 전처리조(100)는 여과 순서에 따라 1차 전처리조(110)와 2차 전처리조(120)로 구획된다.The pretreatment tank 100 and the filtration tank 200 are continuously provided in a divided form in one housing and the pretreatment tank 100 is connected to the first pretreatment tank 110 and the second pretreatment tank 120 .

여기서, 여과막조(200)와 전처리조(100)에는 에어리프트(Air Lift)(210,111)가 설치된다.Air lifts 210 and 111 are installed in the filtration membrane tank 200 and the pretreatment tank 100.

상기 여과막조(200)에 설치된 에어리프트(210)는 여과막조 내의 처리 후 발생되는 슬러지를 1차 전처리조(110)로 인발(반송), 재처리시켜 조내 슬러지의 일정농도 유지가 가능하도록 한다.The air lift 210 installed in the filtration membrane tank 200 allows the sludge generated after the treatment in the filtration membrane tank to be pulled out and reprocessed in the first pre-treatment tank 110 to maintain a constant concentration of sludge in the tank.

상기 2차 전처리조(120)에 설치된 에어리프트(도면에 미도시)는 2차 전처리조 내의 처리 후 발생되는 슬러지를 1차 전처리조(110)로 반송시킨다.An air lift (not shown) provided in the secondary pretreatment tank 120 conveys sludge generated after the treatment in the secondary pretreatment tank to the primary pretreatment tank 110.

상기 1차 전처리조(110)에 설치된 에어리프트(111)는 1차 전처리조 내의 처리 후 발생되는 슬러지를 오수처리시설의 유량조(저류조)(50)로 이송한다.The air lift 111 installed in the first pre-treatment tank 110 transfers the sludge generated after the treatment in the first pre-treatment tank to the flow tank (storage tank) 50 of the wastewater treatment facility.

상기 에어리프트(Ar Lift)는 압축공기를 양액(揚液)관의 하부에 보내면 액에 공기가 혼합되어 관내의 액이 올려져 상단에서 불출됨에 따라 액이 퍼 올려지는 것으로, 기계적인 운동부분이 없이 지하수나 부식성 액체를 수송하는데 많이 사용되는 특수 펌프의 일종이다.The air lift (Ar Lift) sends compressed air to the lower part of the liquid solution pipe. When the liquid is mixed with air, the liquid in the pipe is raised and discharged from the upper part, and the liquid is pumped up. It is a kind of special pump which is used for transporting groundwater or corrosive liquids without.

상기 전처리조(100)의 1차 전처리조(110)는 유분과 협잡물을 제거하기 위해 자갈, 활성탄, 필요에 따른 스펀지 여과망 등을 이용하여 여과시키고, 2차 전처리조(120)는 미세유분을 제거하기 위해 부직포필터를 사용한다.The first pre-treatment tank 110 of the pretreatment tank 100 is filtered using gravel, activated carbon, and a sponge filter net as needed to remove oils and contaminants, and the second pretreatment tank 120 removes fine oil fractions A nonwoven filter is used.

또한, 상기 1차 전처리조(110)의 후단이나 2차 전처리조(120)의 전단 중 어느 한 곳에는 미세 슬러지를 제거하기 위해 활성탄, 와운드필터를 추가로 이용할 수 있다.Activated carbon and a flood filter may be additionally used to remove fine sludge at either the rear end of the first pretreatment tank 110 or the front end of the second pretreatment tank 120.

이렇게 1차 전처리조(110)와 2차 전처리조(120)를 거쳐 협잡물, 침강성 부유물질, 유분 등이 순차적으로 제거되면서도 지상노출형이기 때문에 전체적인 교체작업 없이 계속해서 사용할 수 있게 된다.Since the impurities, precipitated suspended solids, oil and the like are sequentially removed through the first pretreatment tank 110 and the second pretreatment tank 120, they can be continuously used without the entire replacement operation since they are exposed to the ground.

이러한 연속적인 처리과정이 오페수의 흐름에 따라 1차 전처리조(110), 2차 전처리조(120), 여과막조(200)를 통해 원활하게 이루어지도록 1차 전처리조(110), 2차 전처리조(120)에는 월류(T)관(112,122)이 각각 설치된다.In order to smoothly carry out the continuous process through the first pre-treatment tank 110, the second pre-treatment tank 120 and the filtration tank 200 according to the flow of the number of the oepets, a first pre-treatment tank 110, Troughs 112 and 122 are installed in the tank 120, respectively.

그리고, 상기 1차 전처리조(110), 2차 전처리조(120) 하단에 밸브(113,123)를 두고 일정량 이상의 유분 및 협잡물, 인발 오니를 정기적으로 오수처리시설 내 유량조(저류조)(50)로 반송처리한다. 이때 용량에 따라 솔레노이드 밸브 설치 후 자동화시키는 것이 바람직하다.The valves 113 and 123 are disposed at the lower ends of the first pre-treatment tank 110 and the second pre-treatment tank 120 to regularly supply a predetermined amount or more of oil and contaminants and withdrawal sludge to the flow tank (storage tank) 50 in the sewage treatment facility And carries out a return process. At this time, it is preferable to automate the solenoid valve depending on the capacity.

여기서, 상기 여과막조(200) 하단에 밸브(220)를 두고 일정량 이상의 유분 및 협잡물, 인발 오니를 정기적으로 오수처리시설 내 유량조(저류조)(50)로 반송처리하도록 구성할 수 있음은 물론이다.It goes without saying that a valve 220 may be disposed at the lower end of the filtration membrane tank 200 to return a predetermined amount or more of oil, contaminants, and drawing sludge to the flow tank (storage tank) 50 in the sewage treatment facility .

이와 같이 전처리조(100)와 여과막조(200)를 지상노출형으로 함께 설치하여 오수처리시설 최종처리수의 오염부하량에 따른 충격범위를 최소화하고 다량의 유분이 포함되어도 유분만 별도 제거가 용이해질 수 있다.The pretreatment tank 100 and the filtration tank 200 are installed in a ground-exposed manner to minimize the impact range according to the pollutant load of the final treated water of the wastewater treatment facility. Even if a large amount of oil is contained, .

여과막조(200)의 멤브레인 필터(230)는 중공사막 또는 평막이 사용될 수 있으나, 도면에서는 일 실시예로 중공사막이 사용되는 것으로 기재하였다.As the membrane filter 230 of the filtration membrane tank 200, a hollow fiber membrane or a flat membrane may be used, but in the drawings, it is described that a hollow fiber membrane is used as an embodiment.

상기 멤브레인 필터(230)는 직렬연결이 가능하고 수량에 따라 처리용량이 증대될 수 있으며 여러 개의 멤브레인 필터(230) 사이사이에는 활성탄이 충진될 수 있다.The membrane filter 230 can be connected in series and the treatment capacity can be increased according to the number of the membrane filters 230. Activated carbon can be filled between the membrane filters 230.

활성탄 여과조(300)는 상기 여과막조(200) 후의 처리수에 대하여 활성탄 여과를 거쳐 재처리하여 악취 및 색소를 제거한다.The activated carbon filtration tank 300 is subjected to activated carbon filtration to treat the treated water after the filter membrane tank 200 to remove odors and coloring matters.

상기 전처리조(100)로 유입되는 라인 및 여과막조(200)로부터 활성탄 여과조(300)로 배출되는 라인에는 각각 유입수를 육안으로 확인하기 위한 투명유리관(150,250)이 설치되는 것이 바람직하다.The lines flowing into the pretreatment tank 100 and the lines discharged from the filtration membrane tank 200 to the activated carbon filtration tank 300 are preferably provided with transparent glass tubes 150 and 250 for visually confirming influent water.

또한, 상기 1차 전처리조(110), 2차 전처리조(120) 및 여과막조(200)의 상부에는 점검구(도면에 미도시)를 두고 처리상태 및 여과막의 상태를 한눈에 확인가능하도록 구성하는 것이 바람직하다.In addition, an inspection port (not shown in the figure) is provided above the first pre-treatment tank 110, the second pre-treatment tank 120, and the filtration membrane tank 200 so that the state of the treatment membrane and the state of the filtration membrane can be checked at a glance .

상기와 같이 기존의 오수처리시설은 땅에 묻고 처리가 되는지 안되는지 잘 알 수 없는 상태에서 분뇨만 청소하였고, 침지식 분리 여과막을 설치한 오수처리시설도 땅에 묻힌 상태로 가동되어 여과막을 꺼내기 전까지는 그 상태를 알 수가 없었지만, 본 발명은 지상노출형으로 운영 상태를 손쉽게 관찰할 수 있다.As described above, the existing sewage treatment facility is cleaned only in the state where it is not known whether it is buried in the ground and treated or not, and the sewage treatment facility provided with the submerged separation filtration membrane is also operated in a state where it is buried in the ground. Although the state can not be known, the present invention can easily observe the operation state with the ground exposure type.

특히 오수처리시설은 사람의 수작업이 최소화되어도 정상가동이 되어야 하며 방류수 수질 또는 수질기준 안에 들어야 하는데, 본 발명은 전처리 설비 등의 전체 교체 없이 운영가능하고 점검구를 통해 처리상태를 한눈에 살펴보면서 처리수의 상태가 방류수질 기준에 적합하도록 재처리할 수 있다.Particularly, the sewage treatment facility should be in normal operation even if the manual work of the person is minimized, and should be within the discharged water quality or water quality standard. The present invention can be operated without replacing the entire pretreatment facilities, Can be reprocessed to meet the discharge water quality standards.

결과적으로 땅속에 묻는 형태를 벗어나 옥외에 설치하여 운영상태를 손쉽게 관찰하고 기존의 처리장치의 문제점이었던 교체시기를 없앰으로써 청소주기에 발생하는 오폐수의 비정상운영이 사라져 항상 정상운영이 가능해지는 것이다.As a result, it is installed outdoors outside the form buried in the ground to easily observe the operating condition and eliminate the abnormal period of the wastewater generated in the cleaning cycle by eliminating the replacement time which is a problem of the conventional processing apparatus, and the normal operation can be always performed.

이와 같이 본 발명에 따른 바람직한 실시예를 살펴보았으며, 앞서 설명된 실시예 이외에도 본 발명이 그 취지나 범주에서 벗어남이 없이 다른 특정 형태로 구체화될 수 있다는 사실은 해당 기술분야에 있어 통상의 지식을 가진 자에게는 자명한 것이다.It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is self-evident to those who have.

그러므로, 상술된 실시예는 제한적인 것이 아니라 예시적인 것으로 여겨져야 하며, 이에 따라 본 발명은 상술한 설명에 한정되지 않고 첨부된 청구항의 범주 및 그 동등 범위 내에서 변경될 수 있다.Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
